AN8 leads AN4 and G538 through Picton with a late running 2122 empty containerized garbage train from Crisps Creek. Typically worked by two AN Class locomotives, the G Class had been added earlier that morning when the train failed north of Goulburn.

The Great Blue Herons have returned to the West End of Vancouver and will soon be establishing nests in the Stanley Park rookery at the base of my street. This view is out my apartment window, looking towards English Bay and the freighters anchored there--there's also a Horseshoe Bay-Nanimo ferry that can be seen against Bowen Island on the right horizon.

 

Much of Vancouver's shipping is bulk cargo (wood chips, fertilizer, grain, petrolium products, sugar, coal, sulpher, etc.) rather than containerized shipping. As the terminals are fewer and the loading process longer, bulk freighters wait their turn while anchored in English Bay. You can tell by how high they are sitting in the water (how much of the red color is showing) that most of these ships are empty.

In December 1961, the Hamburg-Südamerikanische Dampfschifffahrts-Gesellschaft Eggert & Amsinck launched the brand-new general cargo ship cap San Diego. The vessel was built by Deutsche Werft AG right in Hamburg-Finkenwerder.

 

During its first voyage in 1962. Cap San Diego sailed to Montreal, Baltimore, New York, Recife, Rio de Janeiro, Buenos Aires, Santos, Antwerp, Rotterdam and Bremen before returning to Hamburg, each such round trip takes about 60 days. However, just a few years after its launch, marine bulk cargo transportation, or more specifically, break-bulk cargo transportation, was already rapid moving to the more efficient containerization, and general cargo ships like Cap San Diego were becoming obsolete rapidly.

 

By 1986, the ship was reaching the end of her useful life and scheduled to be broken up and scrapped. At that point, The Free and Hanseatic City of Hamburg decided to buy the Hamburg-built ship and restored her to a floating museum that we see today.

London Docklands is the riverfront and former docks in London. It is located in inner east and southeast London, in the boroughs of Southwark, Tower Hamlets, Lewisham, Newham and Greenwich. The docks were formerly part of the Port of London, at one time the world's largest port. After the docks closed, the area had become derelict and poverty-ridden by the 1980s. The Docklands' regeneration began later that decade; it has been redeveloped principally for commercial and residential use. The name "London Docklands" was used for the first time in a government report on redevelopment plans in 1971 and has since been almost universally adopted. The redevelopment created wealth, but also led to some conflict between the new and old communities in the area.

 

Establishment

In Roman and medieval times, ships arriving in the River Thames tended to dock at small quays in the present-day City of London or Southwark, an area known as the Pool of London. However, these gave no protection against the elements, were vulnerable to thieves and suffered from a lack of space at the quayside. The Howland Great Dock in Rotherhithe (built in 1696, and later to form the core of the Surrey Commercial Docks) was designed to address these problems, providing a large, secure and sheltered anchorage with room for 120 large vessels. It was a major commercial success, and provided for two phases of expansion during the Georgian and Victorian eras.

 

The first of the Georgian docks was the West India (opened in 1802), followed by the London (1805), the East India (also 1805), the Surrey (1807), the Regent's Canal Dock (1820), St Katharine (1828) and the West India South (1829). The Victorian docks were mostly further east, comprising the Royal Victoria (1855), Millwall (1868) and Royal Albert (1880). The King George V Dock (1921) was a late addition.

 

Development

Three principal kinds of docks existed. Wet docks were where ships were laid up at anchor and loaded or unloaded. Dry docks, which were far smaller, took individual ships for repairing. Ships were built at dockyards along the riverside. In addition, the river was lined with innumerable warehouses, piers, jetties and dolphins (mooring points). The various docks tended to specialise in different forms of produce. The Surrey Docks concentrated on timber, for instance; Millwall took grain; St Katharine took wool, sugar and rubber; and so on.

 

The docks required an army of workers, chiefly lightermen (who carried loads between ships and quays aboard small barges called lighters) and quayside workers, who dealt with the goods once they were ashore. Some of the workers were highly skilled: the lightermen had their own livery company or guild, while the deal porters (workers who carried timber) were famous for their acrobatic skills. Most were unskilled and worked as casual labourers. They assembled at certain points, such as pubs, each morning, where they were selected more or less at random by foremen. For these workers, it was effectively a lottery whether they would get work on any particular day. This arrangement continued until as late as 1965, although it was somewhat regularised after the creation of the National Dock Labour Scheme in 1947.

 

The main dockland areas were originally low-lying marshes, mostly unsuitable for agriculture and lightly populated. With the establishment of the docks, the dock workers formed a number of tight-knit local communities with their own distinctive cultures and slang. Due to poor communications with other parts of London, they tended to develop in some isolation. Road access to the Isle of Dogs, for example, was only via two swing bridges. Local sentiment there was so strong that Ted Johns, a local community campaigner, and his supporters, in protest at the lack of social provision from the state, unilaterally declared independence for the area, set up a so-called "Island Council" with Johns himself as its elected leader, and blocked off the two access roads.

 

20th century

The docks were originally built and managed by a number of competing private companies. From 1909, they were managed by the Port of London Authority (PLA) which amalgamated the companies in a bid to make the docks more efficient and improve labour relations. The PLA constructed the last of the docks, the King George V, in 1921, as well as greatly expanding the Tilbury docks.

 

German bombing during the Second World War caused massive damage to the docks, with 380,000 tons of timber destroyed in the Surrey Docks in a single night. Nonetheless, following post-war rebuilding they experienced a resurgence of prosperity in the 1950s. The end came suddenly, between approximately 1960 and 1970, when the shipping industry adopted the newly invented container system of cargo transportation. London's docks were unable to accommodate the much larger vessels needed by containerization, and the shipping industry moved to deep-water ports such as Tilbury and Felixstowe. Between 1960 and 1980, all of London's docks were closed, leaving around eight square miles (21 km2) of derelict land in East London.

 

Redevelopment

Efforts to redevelop the docks began almost as soon as they were closed, although it took a decade for most plans to move beyond the drawing board and another decade for redevelopment to take full effect. The situation was greatly complicated by the large number of landowners involved: the PLA, the Greater London Council (GLC), the British Gas Corporation, five borough councils, British Rail and the Central Electricity Generating Board.

 

To address this problem, in 1981 the Secretary of State for the Environment, Michael Heseltine, formed the London Docklands Development Corporation (LDDC) to redevelop the area. This was a statutory body appointed and funded by central government (a quango), with wide powers to acquire and dispose of land in the Docklands. It also served as the development planning authority for the area.

 

Another important government intervention was the designation in 1982 of an enterprise zone, an area in which businesses were exempt from property taxes and had other incentives, including simplified planning and capital allowances. This made investing in the Docklands a significantly more attractive proposition and was instrumental in starting a property boom in the area.

 

The LDDC was controversial; it was accused of favouring elitist luxury developments rather than affordable housing, and it was unpopular with the local communities, who felt that their needs were not being addressed. Nonetheless, the LDDC was central to a remarkable transformation in the area, although how far it was in control of events is debatable. It was wound up in 1998 when control of the Docklands area was handed back to the respective local authorities.

 

The massive development programme managed by the LDDC during the 1980s and 1990s saw a huge area of the Docklands converted into a mixture of residential, commercial and light industrial space. The clearest symbol of the whole effort was the ambitious Canary Wharf project that constructed Britain's tallest building at the time and established a second business district (CBD) in London. However, there is no evidence that the LDDC foresaw this scale of development; nearby Heron Quays had already been developed as low-density offices when Canary Wharf was proposed, and similar development was already underway on Canary Wharf itself, Limehouse Studios being the most famous occupant.

 

Canary Wharf was far from trouble-free; the property slump of the early 1990s halted further development for several years. Developers found themselves, for a time, saddled with property that they were unable to sell or let.

 

Transport

The Docklands historically had poor transport connections. This was addressed by the LDDC with the construction of the Docklands Light Railway (DLR), which connected the Docklands with the city. According to Transport for London, the owner of the project, it was a remarkably inexpensive development, costing only £77 million in its first phase, as it relied on reusing disused railway infrastructure and derelict land for much of its length. The LDDC originally requested a full London Underground line, but the Government refused to fund it.

 

The LDDC also built the Limehouse Link tunnel, a cut and cover road tunnel linking the Isle of Dogs to The Highway (the A1203 road) at a cost of over £150 million per kilometre, one of the most expensive stretches of road ever built.

 

The LDDC also contributed to the development of London City Airport (IATA airport code LCY), opened in October 1987 on the spine of the Royal Docks.

 

The London Underground's Jubilee line was extended eastwards in 1999; it now serves Rotherhithe/Surrey Quays at Canada Water station, the Isle of Dogs at Canary Wharf tube station, Greenwich at North Greenwich tube station and the nearby Royal Docks at Canning Town station. The DLR was extended in 1994 to serve much of the Royal Docks area when the Beckton branch was opened. The Isle of Dogs branch was extended further south, and in 1999 it began serving Greenwich town centre—including the Cutty Sark museum—Deptford and finally Lewisham. In 2005, a new branch of the DLR opened from Canning Town to serve what used to be the eastern terminus of the North London Line, including a station at London City Airport. It was then further extended to Woolwich Arsenal in 2009.

 

Future developments

Further development projects are being proposed and put into practice within the London Dockland area, such as:

 

Extensions of the DLR, possibly to Dagenham.

Further development of Canada Water.

Redevelopment of Blackwall Basin and Wood Wharf, east of Canary Wharf.

New skyscrapers to be built at Canary Wharf, including the Riverside South towers, the Heron Quays West double-skyscraper development and the North Quay project, consisting of three towers.

In the early 21st century, redevelopment is spreading into the more suburban parts of east and southeast London, and into the parts of the counties of Kent and Essex that abut the Thames Estuary. See Thames Gateway and Lower Lea Valley for further information on this trend.

 

History

The numbers of several London Buses routes are prefixed D for Docklands; all run on the north bank of the River Thames as part of the London bus network, and act as feeder buses to the DLR. The D network was developed in the early stages of Docklands redevelopment; it was originally much larger, but as transport rapidly improved across east London, the need for the D routes reduced. Today only four remain, running primarily in Tower Hamlets and briefly into Newham and Hackney. Stagecoach London operate routes D6, D7 and D8, and Blue Triangle operate route D3.

 

21st century

The population of the Docklands has more than doubled during the last 30 years, and the area has become a major business centre. Canary Wharf has emerged as one of Europe's biggest clusters of skyscrapers and a major extension to the financial services district of the City of London.

 

Although most of the old wharfs and warehouses have been demolished, some have been restored and converted into flats. Many of the docks themselves have survived and are now used as marinas or watersports centres; a major exception is the Surrey Commercial Docks, which are now largely filled in. Although large ships can—and occasionally still do—visit the old docks, all of the commercial traffic has moved downriver further east.

 

The revival of the Docklands has had major effects in other run-down surrounding areas. Greenwich and Deptford are undergoing large-scale redevelopment, chiefly as a result of the improved transport links making them more attractive to commuters.

 

The Docklands' redevelopment has, however, had some less beneficial aspects. The massive property boom and consequent rise in house prices has led to friction between the new arrivals and the old Docklands communities, who have complained of being squeezed out. It has also made for some of the most striking disparities to be seen anywhere in Britain: luxury executive flats constructed alongside run-down public housing estates.

 

The Docklands' status as a symbol of Margaret Thatcher's Britain has also made it a target for terrorists. After a failed attempt to bomb Canary Wharf in 1992, a large IRA bomb exploded at South Quay on 9 February 1996. Two people died in the explosion, forty people were injured and an estimated £150 million of damage was caused. This bombing ended an IRA ceasefire. James McArdle was sentenced to 25 years of jail time but released in 2000 under the terms of the Good Friday Agreement and royal prerogative of mercy officially signed by Queen Elizabeth II.

 

In a further sign of regeneration in the area, the Docklands now has its own symphony orchestra, Docklands Sinfonia; which was formed in January 2009 and is based at St Anne's Limehouse.

 

Economy

The offices of The Independent group of publications were at one time situated in the Docklands. In 2008, Independent News & Media announced that The Independent would be moving its offices to Northcliffe House in Kensington.

 

London's Docklands has become one of the world's leading global internet hubs since the opening in 1990 of the carrier-neutral Telehouse campus, which hosts the vast majority of LINX's internet peering traffic, occupying over 73,000 square metres. In August 2016, Telehouse Europe opened the $177 million North Two data centre of 24,000 square metres that became the only UK data centre to own a 132 kV on-campus grid substation that is directly connected to the National Grid, reducing transmission losses and improving power density and service continuity.

 

The history of London, the capital city of England and the United Kingdom, extends over 2000 years. In that time, it has become one of the world's most significant financial and cultural capital cities. It has withstood plague, devastating fire, civil war, aerial bombardment, terrorist attacks, and riots.

 

The City of London is the historic core of the Greater London metropolis, and is today its primary financial district, it represents only a small part of the wider metropolis.

 

Foundations and prehistory

Some recent discoveries indicate probable very early settlements near the Thames in the London area. In 1993, the remains of a Bronze Age bridge were found on the Thames's south foreshore, upstream of Vauxhall Bridge.[1] This bridge either crossed the Thames or went to a now lost island in the river. Dendrology dated the timbers to between 1750 BC and 1285 BC. In 2001, a further dig found that the timbers were driven vertically into the ground on the south bank of the Thames west of Vauxhall Bridge.

 

In 2010, the foundations of a large timber structure, dated to between 4800 BC and 4500 BC were found, again on the foreshore south of Vauxhall Bridge. The function of the mesolithic structure is not known. All these structures are on the south bank at a natural crossing point where the River Effra flows into the Thames.

 

Archaeologist Leslie Wallace notes, "Because no LPRIA [Late pre-Roman Iron Age] settlements or significant domestic refuse have been found in London, despite extensive archaeological excavation, arguments for a purely Roman foundation of London are now common and uncontroversial."

 

Early history

Roman London (47–410 AD)

Londinium was established as a civilian town by the Romans about four years after the invasion of 43 AD. London, like Rome, was founded on the point of the river where it was narrow enough to bridge and the strategic location of the city provided easy access to much of Europe. Early Roman London occupied a relatively small area, roughly equivalent to the size of Hyde Park. In around 60 AD, it was destroyed by the Iceni led by their queen Boudica. The city was quickly rebuilt as a planned Roman town and recovered after perhaps 10 years; the city grew rapidly over the following decades.

 

Although some sources claim that during the 2nd century Londinium replaced Colchester as the capital of Roman Britain (Britannia) there is no surviving evidence to prove it was ever the capital of Roman Britain. Its population was around 60,000 inhabitants. It boasted major public buildings, including the largest basilica north of the Alps, temples, bath houses, an amphitheatre and a large fort for the city garrison. Political instability and recession from the 3rd century onwards led to a slow decline.

 

At some time between 180 AD and 225 AD, the Romans built the defensive London Wall around the landward side of the city. The wall was about 3 kilometres (1.9 mi) long, 6 metres (20 ft) high, and 2.5 metres (8.2 ft) thick. The wall would survive for another 1,600 years and define the City of London's perimeters for centuries to come. The perimeters of the present City are roughly defined by the line of the ancient wall.

 

Londinium was an ethnically diverse city with inhabitants from across the Roman Empire, including natives of Britannia, continental Europe, the Middle East, and North Africa.[9]

 

In the late 3rd century, Londinium was raided on several occasions by Saxon pirates. This led, from around 255 onwards, to the construction of an additional riverside wall. Six of the traditional seven city gates of London are of Roman origin, namely: Ludgate, Newgate, Aldersgate, Cripplegate, Bishopsgate and Aldgate (Moorgate is the exception, being of medieval origin).

 

By the 5th century, the Roman Empire was in rapid decline and in 410 AD, the Roman occupation of Britannia came to an end. Following this, the Roman city also went into rapid decline and by the end of the 5th century was practically abandoned.

 

Anglo-Saxon London (5th century – 1066)

Until recently it was believed that Anglo-Saxon settlement initially avoided the area immediately around Londinium. However, the discovery in 2008 of an Anglo-Saxon cemetery at Covent Garden indicates that the incomers had begun to settle there at least as early as the 6th century and possibly in the 5th. The main focus of this settlement was outside the Roman walls, clustering a short distance to the west along what is now the Strand, between the Aldwych and Trafalgar Square. It was known as Lundenwic, the -wic suffix here denoting a trading settlement. Recent excavations have also highlighted the population density and relatively sophisticated urban organisation of this earlier Anglo-Saxon London, which was laid out on a grid pattern and grew to house a likely population of 10–12,000.

 

Early Anglo-Saxon London belonged to a people known as the Middle Saxons, from whom the name of the county of Middlesex is derived, but who probably also occupied the approximate area of modern Hertfordshire and Surrey. However, by the early 7th century the London area had been incorporated into the kingdom of the East Saxons. In 604 King Saeberht of Essex converted to Christianity and London received Mellitus, its first post-Roman bishop.

 

At this time Essex was under the overlordship of King Æthelberht of Kent, and it was under Æthelberht's patronage that Mellitus founded the first St. Paul's Cathedral, traditionally said to be on the site of an old Roman Temple of Diana (although Christopher Wren found no evidence of this). It would have only been a modest church at first and may well have been destroyed after he was expelled from the city by Saeberht's pagan successors.

 

The permanent establishment of Christianity in the East Saxon kingdom took place in the reign of King Sigeberht II in the 650s. During the 8th century, the kingdom of Mercia extended its dominance over south-eastern England, initially through overlordship which at times developed into outright annexation. London seems to have come under direct Mercian control in the 730s.

 

Viking attacks dominated most of the 9th century, becoming increasingly common from around 830 onwards. London was sacked in 842 and again in 851. The Danish "Great Heathen Army", which had rampaged across England since 865, wintered in London in 871. The city remained in Danish hands until 886, when it was captured by the forces of King Alfred the Great of Wessex and reincorporated into Mercia, then governed under Alfred's sovereignty by his son-in-law Ealdorman Æthelred.

 

Around this time the focus of settlement moved within the old Roman walls for the sake of defence, and the city became known as Lundenburh. The Roman walls were repaired and the defensive ditch re-cut, while the bridge was probably rebuilt at this time. A second fortified Borough was established on the south bank at Southwark, the Suthringa Geworc (defensive work of the men of Surrey). The old settlement of Lundenwic became known as the ealdwic or "old settlement", a name which survives today as Aldwich.

 

From this point, the City of London began to develop its own unique local government. Following Æthelred's death in 911 it was transferred to Wessex, preceding the absorption of the rest of Mercia in 918. Although it faced competition for political pre-eminence in the united Kingdom of England from the traditional West Saxon centre of Winchester, London's size and commercial wealth brought it a steadily increasing importance as a focus of governmental activity. King Athelstan held many meetings of the witan in London and issued laws from there, while King Æthelred the Unready issued the Laws of London there in 978.

 

Following the resumption of Viking attacks in the reign of Æthelred, London was unsuccessfully attacked in 994 by an army under King Sweyn Forkbeard of Denmark. As English resistance to the sustained and escalating Danish onslaught finally collapsed in 1013, London repulsed an attack by the Danes and was the last place to hold out while the rest of the country submitted to Sweyn, but by the end of the year it too capitulated and Æthelred fled abroad. Sweyn died just five weeks after having been proclaimed king and Æthelred was restored to the throne, but Sweyn's son Cnut returned to the attack in 1015.

 

After Æthelred's death at London in 1016 his son Edmund Ironside was proclaimed king there by the witangemot and left to gather forces in Wessex. London was then subjected to a systematic siege by Cnut but was relieved by King Edmund's army; when Edmund again left to recruit reinforcements in Wessex the Danes resumed the siege but were again unsuccessful. However, following his defeat at the Battle of Assandun Edmund ceded to Cnut all of England north of the Thames, including London, and his death a few weeks later left Cnut in control of the whole country.

 

A Norse saga tells of a battle when King Æthelred returned to attack Danish-occupied London. According to the saga, the Danes lined London Bridge and showered the attackers with spears. Undaunted, the attackers pulled the roofs off nearby houses and held them over their heads in the boats. Thus protected, they were able to get close enough to the bridge to attach ropes to the piers and pull the bridge down, thus ending the Viking occupation of London. This story presumably relates to Æthelred's return to power after Sweyn's death in 1014, but there is no strong evidence of any such struggle for control of London on that occasion.

 

Following the extinction of Cnut's dynasty in 1042 English rule was restored under Edward the Confessor. He was responsible for the foundation of Westminster Abbey and spent much of his time at Westminster, which from this time steadily supplanted the City itself as the centre of government. Edward's death at Westminster in 1066 without a clear heir led to a succession dispute and the Norman conquest of England. Earl Harold Godwinson was elected king by the witangemot and crowned in Westminster Abbey but was defeated and killed by William the Bastard, Duke of Normandy at the Battle of Hastings. The surviving members of the witan met in London and elected King Edward's young nephew Edgar the Ætheling as king.

 

The Normans advanced to the south bank of the Thames opposite London, where they defeated an English attack and burned Southwark but were unable to storm the bridge. They moved upstream and crossed the river at Wallingford before advancing on London from the north-west. The resolve of the English leadership to resist collapsed and the chief citizens of London went out together with the leading members of the Church and aristocracy to submit to William at Berkhamstead, although according to some accounts there was a subsequent violent clash when the Normans reached the city. Having occupied London, William was crowned king in Westminster Abbey.

 

Norman and Medieval London (1066 – late 15th century)

The new Norman regime established new fortresses within the city to dominate the native population. By far the most important of these was the Tower of London at the eastern end of the city, where the initial timber fortification was rapidly replaced by the construction of the first stone castle in England. The smaller forts of Baynard's Castle and Montfichet's Castle were also established along the waterfront. King William also granted a charter in 1067 confirming the city's existing rights, privileges and laws. London was a centre of England's nascent Jewish population, the first of whom arrived in about 1070. Its growing self-government was consolidated by the election rights granted by King John in 1199 and 1215.

 

On 17 October 1091 a tornado rated T8 on the TORRO scale (equivalent to an F4 on the Fujita scale) hit London; it directly struck the church of St. Mary-le-Bow; four rafters 7.9 meters long (26 feet) were said to have been buried so deep into the ground that only 1.2 meters (4 feet) was visible. Other churches in the area were destroyed as well; it was reported to have also destroyed over 600 houses (although most of them were primarily wood) and hit the London Bridge, after the tornado the bridge was rebuilt in stone. The tornado caused 2 deaths and an unknown number of injuries; this tornado is mentioned in chronicles by Florence of Worcester and William of Malmesbury, the latter of the two describing it as "a great spectacle for those watching from afar, but a terrifying experience for those standing near".

 

In 1097, William Rufus, the son of William the Conqueror, began the construction of 'Westminster Hall', which became the focus of the Palace of Westminster.

 

In 1176, construction began of the most famous incarnation of London Bridge (completed in 1209), which was built on the site of several earlier timber bridges. This bridge would last for 600 years, and remained the only bridge across the River Thames until 1739.

 

Violence against Jews took place in 1190, after it was rumoured that the new King had ordered their massacre after they had presented themselves at his coronation.

 

In 1216, during the First Barons' War London was occupied by Prince Louis of France, who had been called in by the baronial rebels against King John and was acclaimed as King of England in St Paul's Cathedral. However, following John's death in 1217 Louis's supporters reverted to their Plantagenet allegiance, rallying round John's son Henry III, and Louis was forced to withdraw from England.

 

In 1224, after an accusation of ritual murder, the Jewish community was subjected to a steep punitive levy. Then in 1232, Henry III confiscated the principal synagogue of the London Jewish community because he claimed their chanting was audible in a neighboring church. In 1264, during the Second Barons' War, Simon de Montfort's rebels occupied London and killed 500 Jews while attempting to seize records of debts.

 

London's Jewish community was forced to leave England by the expulsion by Edward I in 1290. They left for France, Holland and further afield; their property was seized, and many suffered robbery and murder as they departed.

 

Over the following centuries, London would shake off the heavy French cultural and linguistic influence which had been there since the times of the Norman conquest. The city would figure heavily in the development of Early Modern English.

 

During the Peasants' Revolt of 1381, London was invaded by rebels led by Wat Tyler. A group of peasants stormed the Tower of London and executed the Lord Chancellor, Archbishop Simon Sudbury, and the Lord Treasurer. The peasants looted the city and set fire to numerous buildings. Tyler was stabbed to death by the Lord Mayor William Walworth in a confrontation at Smithfield and the revolt collapsed.

 

Trade increased steadily during the Middle Ages, and London grew heavily as a result. In 1100, London's population was somewhat more than 15,000. By 1300, it had grown to roughly 80,000. London lost at least half of its population during the Black Death in the mid-14th century, but its economic and political importance stimulated a quick recovery despite further epidemics. Trade in London was organised into various guilds, which effectively controlled the city, and elected the Lord Mayor of the City of London.

 

Medieval London was made up of narrow and twisting streets, and most of the buildings were made from combustible materials such as timber and straw, which made fire a constant threat, while sanitation in cities was of low-quality.

 

Modern history

Tudor London (1485–1604)

In 1475, the Hanseatic League set up its main English trading base (kontor) in London, called Stalhof or Steelyard. It existed until 1853, when the Hanseatic cities of Lübeck, Bremen and Hamburg sold the property to South Eastern Railway. Woollen cloth was shipped undyed and undressed from 14th/15th century London to the nearby shores of the Low Countries, where it was considered indispensable.

 

During the Reformation, London was the principal early centre of Protestantism in England. Its close commercial connections with the Protestant heartlands in northern continental Europe, large foreign mercantile communities, disproportionately large number of literate inhabitants and role as the centre of the English print trade all contributed to the spread of the new ideas of religious reform. Before the Reformation, more than half of the area of London was the property of monasteries, nunneries and other religious houses.

 

Henry VIII's "Dissolution of the Monasteries" had a profound effect on the city as nearly all of this property changed hands. The process started in the mid-1530s, and by 1538 most of the larger monastic houses had been abolished. Holy Trinity Aldgate went to Lord Audley, and the Marquess of Winchester built himself a house in part of its precincts. The Charterhouse went to Lord North, Blackfriars to Lord Cobham, the leper hospital of St Giles to Lord Dudley, while the king took for himself the leper hospital of St James, which was rebuilt as St James's Palace.

 

The period saw London rapidly rising in importance among Europe's commercial centres. Trade expanded beyond Western Europe to Russia, the Levant, and the Americas. This was the period of mercantilism and monopoly trading companies such as the Muscovy Company (1555) and the British East India Company (1600) were established in London by royal charter. The latter, which ultimately came to rule India, was one of the key institutions in London, and in Britain as a whole, for two and a half centuries. Immigrants arrived in London not just from all over England and Wales, but from abroad as well, for example Huguenots from France; the population rose from an estimated 50,000 in 1530 to about 225,000 in 1605. The growth of the population and wealth of London was fuelled by a vast expansion in the use of coastal shipping.

 

The late 16th and early 17th century saw the great flourishing of drama in London whose preeminent figure was William Shakespeare. During the mostly calm later years of Elizabeth's reign, some of her courtiers and some of the wealthier citizens of London built themselves country residences in Middlesex, Essex and Surrey. This was an early stirring of the villa movement, the taste for residences which were neither of the city nor on an agricultural estate, but at the time of Elizabeth's death in 1603, London was still relatively compact.

 

Xenophobia was rampant in London, and increased after the 1580s. Many immigrants became disillusioned by routine threats of violence and molestation, attempts at expulsion of foreigners, and the great difficulty in acquiring English citizenship. Dutch cities proved more hospitable, and many left London permanently. Foreigners are estimated to have made up 4,000 of the 100,000 residents of London by 1600, many being Dutch and German workers and traders.

 

Stuart London (1603–1714)

Paul's Cathedral had lost its spire by this time. The two theatres on the foreground (Southwark) side of the Thames are The Bear Garden and The Globe. The large church in the foreground is St Mary Overie, now Southwark Cathedral.

London's expansion beyond the boundaries of the City was decisively established in the 17th century. In the opening years of that century the immediate environs of the City, with the principal exception of the aristocratic residences in the direction of Westminster, were still considered not conducive to health. Immediately to the north was Moorfields, which had recently been drained and laid out in walks, but it was frequented by beggars and travellers, who crossed it in order to get into London. Adjoining Moorfields were Finsbury Fields, a favourite practising ground for the archers, Mile End, then a common on the Great Eastern Road and famous as a rendezvous for the troops.

 

The preparations for King James I becoming king were interrupted by a severe plague epidemic, which may have killed over thirty thousand people. The Lord Mayor's Show, which had been discontinued for some years, was revived by order of the king in 1609. The dissolved monastery of the Charterhouse, which had been bought and sold by the courtiers several times, was purchased by Thomas Sutton for £13,000. The new hospital, chapel, and schoolhouse were begun in 1611. Charterhouse School was to be one of the principal public schools in London until it moved to Surrey in the Victorian era, and the site is still used as a medical school.

 

The general meeting-place of Londoners in the day-time was the nave of Old St. Paul's Cathedral. Merchants conducted business in the aisles, and used the font as a counter upon which to make their payments; lawyers received clients at their particular pillars; and the unemployed looked for work. St Paul's Churchyard was the centre of the book trade and Fleet Street was a centre of public entertainment. Under James I the theatre, which established itself so firmly in the latter years of Elizabeth, grew further in popularity. The performances at the public theatres were complemented by elaborate masques at the royal court and at the inns of court.

 

Charles I acceded to the throne in 1625. During his reign, aristocrats began to inhabit the West End in large numbers. In addition to those who had specific business at court, increasing numbers of country landowners and their families lived in London for part of the year simply for the social life. This was the beginning of the "London season". Lincoln's Inn Fields was built about 1629. The piazza of Covent Garden, designed by England's first classically trained architect Inigo Jones followed in about 1632. The neighbouring streets were built shortly afterwards, and the names of Henrietta, Charles, James, King and York Streets were given after members of the royal family.

 

In January 1642 five members of parliament whom the King wished to arrest were granted refuge in the City. In August of the same year the King raised his banner at Nottingham, and during the English Civil War London took the side of the parliament. Initially the king had the upper hand in military terms and in November he won the Battle of Brentford a few miles to the west of London. The City organised a new makeshift army and Charles hesitated and retreated.

 

Subsequently, an extensive system of fortifications was built to protect London from a renewed attack by the Royalists. This comprised a strong earthen rampart, enhanced with bastions and redoubts. It was well beyond the City walls and encompassed the whole urban area, including Westminster and Southwark. London was not seriously threatened by the royalists again, and the financial resources of the City made an important contribution to the parliamentarians' victory in the war.

 

The unsanitary and overcrowded City of London has suffered from the numerous outbreaks of the plague many times over the centuries, but in Britain it is the last major outbreak which is remembered as the "Great Plague" It occurred in 1665 and 1666 and killed around 60,000 people, which was one fifth of the population. Samuel Pepys chronicled the epidemic in his diary. On 4 September 1665 he wrote "I have stayed in the city till above 7400 died in one week, and of them about 6000 of the plague, and little noise heard day or night but tolling of bells."

 

Great Fire of London (1666)

The Great Plague was immediately followed by another catastrophe, albeit one which helped to put an end to the plague. On the Sunday, 2 September 1666 the Great Fire of London broke out at one o'clock in the morning at a bakery in Pudding Lane in the southern part of the City. Fanned by an eastern wind the fire spread, and efforts to arrest it by pulling down houses to make firebreaks were disorganised to begin with. On Tuesday night the wind fell somewhat, and on Wednesday the fire slackened. On Thursday it was extinguished, but on the evening of that day the flames again burst forth at the Temple. Some houses were at once blown up by gunpowder, and thus the fire was finally mastered. The Monument was built to commemorate the fire: for over a century and a half it bore an inscription attributing the conflagration to a "popish frenzy".

 

The fire destroyed about 60% of the City, including Old St Paul's Cathedral, 87 parish churches, 44 livery company halls and the Royal Exchange. However, the number of lives lost was surprisingly small; it is believed to have been 16 at most. Within a few days of the fire, three plans were presented to the king for the rebuilding of the city, by Christopher Wren, John Evelyn and Robert Hooke.

 

Wren proposed to build main thoroughfares north and south, and east and west, to insulate all the churches in conspicuous positions, to form the most public places into large piazzas, to unite the halls of the 12 chief livery companies into one regular square annexed to the Guildhall, and to make a fine quay on the bank of the river from Blackfriars to the Tower of London. Wren wished to build the new streets straight and in three standard widths of thirty, sixty and ninety feet. Evelyn's plan differed from Wren's chiefly in proposing a street from the church of St Dunstan's in the East to the St Paul's, and in having no quay or terrace along the river. These plans were not implemented, and the rebuilt city generally followed the streetplan of the old one, and most of it has survived into the 21st century.

 

Nonetheless, the new City was different from the old one. Many aristocratic residents never returned, preferring to take new houses in the West End, where fashionable new districts such as St. James's were built close to the main royal residence, which was Whitehall Palace until it was destroyed by fire in the 1690s, and thereafter St. James's Palace. The rural lane of Piccadilly sprouted courtiers mansions such as Burlington House. Thus the separation between the middle class mercantile City of London, and the aristocratic world of the court in Westminster became complete.

 

In the City itself there was a move from wooden buildings to stone and brick construction to reduce the risk of fire. Parliament's Rebuilding of London Act 1666 stated "building with brick [is] not only more comely and durable, but also more safe against future perils of fire". From then on only doorcases, window-frames and shop fronts were allowed to be made of wood.

 

Christopher Wren's plan for a new model London came to nothing, but he was appointed to rebuild the ruined parish churches and to replace St Paul's Cathedral. His domed baroque cathedral was the primary symbol of London for at least a century and a half. As city surveyor, Robert Hooke oversaw the reconstruction of the City's houses. The East End, that is the area immediately to the east of the city walls, also became heavily populated in the decades after the Great Fire. London's docks began to extend downstream, attracting many working people who worked on the docks themselves and in the processing and distributive trades. These people lived in Whitechapel, Wapping, Stepney and Limehouse, generally in slum conditions.

 

In the winter of 1683–1684, a frost fair was held on the Thames. The frost, which began about seven weeks before Christmas and continued for six weeks after, was the greatest on record. The Revocation of the Edict of Nantes in 1685 led to a large migration of Huguenots to London. They established a silk industry at Spitalfields.

 

At this time the Bank of England was founded, and the British East India Company was expanding its influence. Lloyd's of London also began to operate in the late 17th century. In 1700, London handled 80% of England's imports, 69% of its exports and 86% of its re-exports. Many of the goods were luxuries from the Americas and Asia such as silk, sugar, tea and tobacco. The last figure emphasises London's role as an entrepot: while it had many craftsmen in the 17th century, and would later acquire some large factories, its economic prominence was never based primarily on industry. Instead it was a great trading and redistribution centre. Goods were brought to London by England's increasingly dominant merchant navy, not only to satisfy domestic demand, but also for re-export throughout Europe and beyond.

 

William III, a Dutchman, cared little for London, the smoke of which gave him asthma, and after the first fire at Whitehall Palace (1691) he purchased Nottingham House and transformed it into Kensington Palace. Kensington was then an insignificant village, but the arrival of the court soon caused it to grow in importance. The palace was rarely favoured by future monarchs, but its construction was another step in the expansion of the bounds of London. During the same reign Greenwich Hospital, then well outside the boundary of London, but now comfortably inside it, was begun; it was the naval complement to the Chelsea Hospital for former soldiers, which had been founded in 1681. During the reign of Queen Anne an act was passed authorising the building of 50 new churches to serve the greatly increased population living outside the boundaries of the City of London.

 

A view of London from the east in 1751

The 18th century was a period of rapid growth for London, reflecting an increasing national population, the early stirrings of the Industrial Revolution, and London's role at the centre of the evolving British Empire.

 

In 1707, an Act of Union was passed merging the Scottish and the English Parliaments, thus establishing the Kingdom of Great Britain. A year later, in 1708 Christopher Wren's masterpiece, St Paul's Cathedral was completed on his birthday. However, the first service had been held on 2nd of December 1697; more than 10 years earlier. This Cathedral replaced the original St. Paul's which had been completely destroyed in the Great Fire of London. This building is considered one of the finest in Britain and a fine example of Baroque architecture.

 

Many tradesmen from different countries came to London to trade goods and merchandise. Also, more immigrants moved to London making the population greater. More people also moved to London for work and for business making London an altogether bigger and busier city. Britain's victory in the Seven Years' War increased the country's international standing and opened large new markets to British trade, further boosting London's prosperity.

 

During the Georgian period London spread beyond its traditional limits at an accelerating pace. This is shown in a series of detailed maps, particularly John Rocque's 1741–45 map (see below) and his 1746 Map of London. New districts such as Mayfair were built for the rich in the West End, new bridges over the Thames encouraged an acceleration of development in South London and in the East End, the Port of London expanded downstream from the City. During this period was also the uprising of the American colonies.

 

In 1780, the Tower of London held its only American prisoner, former President of the Continental Congress, Henry Laurens. In 1779, he was the Congress's representative of Holland, and got the country's support for the Revolution. On his return voyage back to America, the Royal Navy captured him and charged him with treason after finding evidence of a reason of war between Great Britain and the Netherlands. He was released from the Tower on 21 December 1781 in exchange for General Lord Cornwallis.

 

In 1762, George III acquired Buckingham Palace (then called Buckingham House) from the Duke of Buckingham. It was enlarged over the next 75 years by architects such as John Nash.

 

A phenomenon of the era was the coffeehouse, which became a popular place to debate ideas. Growing literacy and the development of the printing press meant that news became widely available. Fleet Street became the centre of the embryonic national press during the century.

 

18th-century London was dogged by crime. The Bow Street Runners were established in 1750 as a professional police force. Penalties for crime were harsh, with the death penalty being applied for fairly minor crimes. Public hangings were common in London, and were popular public events.

 

In 1780, London was rocked by the Gordon Riots, an uprising by Protestants against Roman Catholic emancipation led by Lord George Gordon. Severe damage was caused to Catholic churches and homes, and 285 rioters were killed.

 

Up until 1750, London Bridge was the only crossing over the Thames, but in that year Westminster Bridge was opened and, for the first time in history, London Bridge, in a sense, had a rival. In 1798, Frankfurt banker Nathan Mayer Rothschild arrived in London and set up a banking house in the city, with a large sum of money given to him by his father, Amschel Mayer Rothschild. The Rothschilds also had banks in Paris and Vienna. The bank financed numerous large-scale projects, especially regarding railways around the world and the Suez Canal.

 

The 18th century saw the breakaway of the American colonies and many other unfortunate events in London, but also great change and Enlightenment. This all led into the beginning of modern times, the 19th century.

 

19th century

During the 19th century, London was transformed into the world's largest city and capital of the British Empire. Its population expanded from 1 million in 1800 to 6.7 million a century later. During this period, London became a global political, financial, and trading capital. In this position, it was largely unrivalled until the latter part of the century, when Paris and New York began to threaten its dominance.

 

While the city grew wealthy as Britain's holdings expanded, 19th-century London was also a city of poverty, where millions lived in overcrowded and unsanitary slums. Life for the poor was immortalised by Charles Dickens in such novels as Oliver Twist.

 

In 1829, the then Home Secretary (and future prime minister) Robert Peel established the Metropolitan Police as a police force covering the entire urban area. The force gained the nickname of "bobbies" or "peelers" named after Robert Peel.

 

19th-century London was transformed by the coming of the railways. A new network of metropolitan railways allowed for the development of suburbs in neighbouring counties from which middle-class and wealthy people could commute to the centre. While this spurred the massive outward growth of the city, the growth of greater London also exacerbated the class divide, as the wealthier classes emigrated to the suburbs, leaving the poor to inhabit the inner city areas.

 

The first railway to be built in London was a line from London Bridge to Greenwich, which opened in 1836. This was soon followed by the opening of great rail termini which eventually linked London to every corner of Great Britain, including Euston station (1837), Paddington station (1838), Fenchurch Street station (1841), Waterloo station (1848), King's Cross station (1850), and St Pancras station (1863). From 1863, the first lines of the London Underground were constructed.

 

The urbanised area continued to grow rapidly, spreading into Islington, Paddington, Belgravia, Holborn, Finsbury, Shoreditch, Southwark and Lambeth. Towards the middle of the century, London's antiquated local government system, consisting of ancient parishes and vestries, struggled to cope with the rapid growth in population. In 1855, the Metropolitan Board of Works (MBW) was created to provide London with adequate infrastructure to cope with its growth. One of its first tasks was addressing London's sanitation problems. At the time, raw sewage was pumped straight into the River Thames. This culminated in The Great Stink of 1858.

 

Parliament finally gave consent for the MBW to construct a large system of sewers. The engineer put in charge of building the new system was Joseph Bazalgette. In what was one of the largest civil engineering projects of the 19th century, he oversaw construction of over 2100 km of tunnels and pipes under London to take away sewage and provide clean drinking water. When the London sewerage system was completed, the death toll in London dropped dramatically, and epidemics of cholera and other diseases were curtailed. Bazalgette's system is still in use today.

 

One of the most famous events of 19th-century London was the Great Exhibition of 1851. Held at The Crystal Palace, the fair attracted 6 million visitors from across the world and displayed Britain at the height of its Imperial dominance.

 

As the capital of a massive empire, London became a magnet for immigrants from the colonies and poorer parts of Europe. A large Irish population settled in the city during the Victorian period, with many of the newcomers refugees from the Great Famine (1845–1849). At one point, Catholic Irish made up about 20% of London's population; they typically lived in overcrowded slums. London also became home to a sizable Jewish community, which was notable for its entrepreneurship in the clothing trade and merchandising.

 

In 1888, the new County of London was established, administered by the London County Council. This was the first elected London-wide administrative body, replacing the earlier Metropolitan Board of Works, which had been made up of appointees. The County of London covered broadly what was then the full extent of the London conurbation, although the conurbation later outgrew the boundaries of the county. In 1900, the county was sub-divided into 28 metropolitan boroughs, which formed a more local tier of administration than the county council.

 

Many famous buildings and landmarks of London were constructed during the 19th century including:

Trafalgar Square

Big Ben and the Houses of Parliament

The Royal Albert Hall

The Victoria and Albert Museum

Tower Bridge

20th century

 

1900 to 1939

London entered the 20th century at the height of its influence as the capital of one of the largest empires in history, but the new century was to bring many challenges.

 

London's population continued to grow rapidly in the early decades of the century, and public transport was greatly expanded. A large tram network was constructed by the London County Council, through the LCC Tramways; the first motorbus service began in the 1900s. Improvements to London's overground and underground rail network, including large scale electrification were progressively carried out.

 

During World War I, London experienced its first bombing raids carried out by German zeppelin airships; these killed around 700 people and caused great terror, but were merely a foretaste of what was to come. The city of London would experience many more terrors as a result of both World Wars. The largest explosion in London occurred during World War I: the Silvertown explosion, when a munitions factory containing 50 tons of TNT exploded, killing 73 and injuring 400.

 

The period between the two World Wars saw London's geographical extent growing more quickly than ever before or since. A preference for lower density suburban housing, typically semi-detached, by Londoners seeking a more "rural" lifestyle, superseded Londoners' old predilection for terraced houses. This was facilitated not only by a continuing expansion of the rail network, including trams and the Underground, but also by slowly widening car ownership. London's suburbs expanded outside the boundaries of the County of London, into the neighbouring counties of Essex, Hertfordshire, Kent, Middlesex and Surrey.

 

Like the rest of the country, London suffered severe unemployment during the Great Depression of the 1930s. In the East End during the 1930s, politically extreme parties of both right and left flourished. The Communist Party of Great Britain and the British Union of Fascists both gained serious support. Clashes between right and left culminated in the Battle of Cable Street in 1936. The population of London reached an all-time peak of 8.6 million in 1939.

 

Large numbers of Jewish immigrants fleeing from Nazi Germany settled in London during the 1930s, mostly in the East End.

 

Labour Party politician Herbert Morrison was a dominant figure in local government in the 1920s and 1930s. He became mayor of Hackney and a member of the London County Council in 1922, and for a while was Minister of Transport in Ramsay MacDonald's cabinet. When Labour gained power in London in 1934, Morrison unified the bus, tram and trolleybus services with the Underground, by the creation of the London Passenger Transport Board (known as London Transport) in 1933., He led the effort to finance and build the new Waterloo Bridge. He designed the Metropolitan Green Belt around the suburbs and worked to clear slums, build schools, and reform public assistance.

 

In World War II

During World War II, London, as many other British cities, suffered severe damage, being bombed extensively by the Luftwaffe as a part of The Blitz. Prior to the bombing, hundreds of thousands of children in London were evacuated to the countryside to avoid the bombing. Civilians took shelter from the air raids in underground stations.

 

The heaviest bombing took place during The Blitz between 7 September 1940 and 10 May 1941. During this period, London was subjected to 71 separate raids receiving over 18,000 tonnes of high explosive. One raid in December 1940, which became known as the Second Great Fire of London, saw a firestorm engulf much of the City of London and destroy many historic buildings. St Paul's Cathedral, however, remained unscathed; a photograph showing the cathedral shrouded in smoke became a famous image of the war.

 

Having failed to defeat Britain, Hitler turned his attention to the Eastern front and regular bombing raids ceased. They began again, but on a smaller scale with the "Little Blitz" in early 1944. Towards the end of the war, during 1944/45 London again came under heavy attack by pilotless V-1 flying bombs and V-2 rockets, which were fired from Nazi occupied Europe. These attacks only came to an end when their launch sites were captured by advancing Allied forces.

 

London suffered severe damage and heavy casualties, the worst hit part being the Docklands area. By the war's end, just under 30,000 Londoners had been killed by the bombing, and over 50,000 seriously injured, tens of thousands of buildings were destroyed, and hundreds of thousands of people were made homeless.

 

1945–2000

Three years after the war, the 1948 Summer Olympics were held at the original Wembley Stadium, at a time when the city had barely recovered from the war. London's rebuilding was slow to begin. However, in 1951 the Festival of Britain was held, which marked an increasing mood of optimism and forward looking.

 

In the immediate postwar years housing was a major issue in London, due to the large amount of housing which had been destroyed in the war. The authorities decided upon high-rise blocks of flats as the answer to housing shortages. During the 1950s and 1960s the skyline of London altered dramatically as tower blocks were erected, although these later proved unpopular. In a bid to reduce the number of people living in overcrowded housing, a policy was introduced of encouraging people to move into newly built new towns surrounding London. Living standards also rose, with real earnings rising by approximately 70.% in the 20 years after the end of the war.

 

Through the 19th and in the early half of the 20th century, Londoners used coal for heating their homes, which produced large amounts of smoke. In combination with climatic conditions this often caused a characteristic smog, and London became known for its typical "London Fog", also known as "Pea Soupers". London was sometimes referred to as "The Smoke" because of this. In 1952, this culminated in the disastrous Great Smog of 1952 which lasted for five days and killed over 4,000 people. In response to this, the Clean Air Act 1956 was passed, mandating the creating of "smokeless zones" where the use of "smokeless" fuels was required (this was at a time when most households still used open fires); the Act was effective.

 

Starting in the mid-1960s, and partly as a result of the success of such UK musicians as the Beatles and The Rolling Stones, London became a centre for the worldwide youth culture, exemplified by the Swinging London subculture which made Carnaby Street a household name of youth fashion around the world. London's role as a trendsetter for youth fashion continued strongly in the 1980s during the new wave and punk eras and into the mid-1990s with the emergence of the Britpop era.

 

From the 1950s onwards London experienced an increase in immigration, largely from Commonwealth countries such as Jamaica, India, Bangladesh and Pakistan. However, the integration of the new immigrants was not always easy. Racial tensions emerged in events such as the Brixton Riots in the early 1980s.

 

From the beginning of "The Troubles" in Northern Ireland in the early 1970s until the mid-1990s, London was subjected to repeated terrorist attacks by the Provisional IRA.

 

The outward expansion of London was slowed by the war, and the introduction of the Metropolitan Green Belt. Due to this outward expansion, in 1965 the old County of London (which by now only covered part of the London conurbation) and the London County Council were abolished, and the much larger area of Greater London was established with a new Greater London Council (GLC) to administer it, along with 32 new London boroughs.

 

Greater London's population declined steadily in the decades after World War II, from an estimated peak of 8.6 million in 1939 to around 6.8 million in the 1980s. However, it then began to increase again in the late 1980s, encouraged by strong economic performance and an increasingly positive image.

 

London's traditional status as a major port declined dramatically in the post-war decades as the old Docklands could not accommodate large modern container ships. The principal ports for London moved downstream to the ports of Felixstowe and Tilbury. The docklands area had become largely derelict by the 1980s, but was redeveloped into flats and offices from the mid-1980s onwards. The Thames Barrier was completed in the 1980s to protect London against tidal surges from the North Sea.

 

In the early 1980s political disputes between the GLC run by Ken Livingstone and the Conservative government of Margaret Thatcher led to the GLC's abolition in 1986, with most of its powers relegated to the London boroughs. This left London as the only large metropolis in the world without a central administration.

 

In 2000, London-wide government was restored, with the creation of the Greater London Authority (GLA) by Tony Blair's government, covering the same area of Greater London. The new authority had similar powers to the old GLC, but was made up of a directly elected Mayor and a London Assembly. The first election took place on 4 May, with Ken Livingstone comfortably regaining his previous post, becoming first elected mayor of London. London was recognised as one of the nine regions of England. In global perspective, it was emerging as a World city widely compared to New York and Tokyo.

 

21st century

Around the start of the 21st century, London hosted the much derided Millennium Dome at Greenwich, to mark the new century.[50] Other Millennium projects were more successful. One was the largest observation wheel in the world, the "Millennium Wheel", or the London Eye, which was erected as a temporary structure, but soon became a fixture, and draws four million visitors a year. The National Lottery also released a flood of funds for major enhancements to existing attractions, for example the roofing of the Great Court at the British Museum.

 

The London Plan, published by the Mayor of London in 2004, estimated that the population would reach 8.1 million by 2016, and continue to rise thereafter. This was reflected in a move towards denser, more urban styles of building, including a greatly increased number of tall buildings, and proposals for major enhancements to the public transport network. However, funding for projects such as Crossrail remained a struggle.

 

On 6 July 2005 London won the right to host the 2012 Olympics and Paralympics making it the first city to host the modern games three times. However, celebrations were cut short the following day when the city was rocked by a series of terrorist attacks. More than 50 were killed and 750 injured in three bombings on London Underground trains and a fourth on a double decker bus near King's Cross.

 

London was the starting point for countrywide riots which occurred in August 2011, when thousands of people rioted in several city boroughs and in towns across England. They were the biggest riots in modern English history. In 2011, the population grew over 8 million people for the first time in decades. White British formed less than half of the population for the first time.

 

In the public there was ambivalence leading-up to the 2012 Summer Olympics in the city,[58] though public sentiment changed strongly in their favour following a successful opening ceremony and when the anticipated organisational and transport problems never occurred.

 

Boris Johnson, later Prime Minister of the United Kingdom and Leader of the Conservative Party, served as mayor of London from 1 May 2008 until 5 May 2016, being elected in 2008 and reelected in 2012.

 

In the 2016 United Kingdom European Union membership referendum, London was the only region in England, where Remain won the highest share of the vote. The voter turnout was the highest in London since the 1950 general election. However, Britain’s exit from the European Union (EU) in early 2021 (Brexit) only marginally weakened London’s position as an international financial center (IFC).

 

In May 2021, Sadiq Khan, the first Muslim mayor of a major Western capital city, won a second term as London's mayor.

 

In 2022, the Elizabeth line railway opened, connecting Heathrow and Reading to Shenfield and Abbey Wood through a tunnel in the city between Paddington and Liverpool Street, revolutionising east-west travel in London.

 

On 6 May 2023, the coronation of Charles III and his wife, Camilla, as king and queen of the United Kingdom and the other Commonwealth realms, took place at Westminster Abbey, London.

You have probably heard the ongoing urban legend that George Lucas got his idea for the Star Wars AT-AT Walkers from the Port of Oakland Shipping Container Cranes while flying into Oakland International Airport.

 

The taller cranes, are able to reach 141 feet above the dock at the International Port of Oakland. They have the height to load and unload ships with capacity up to 14,000 20-foot containers. Those are the biggest vessels calling in the U.S.

The four cranes each weigh 1,380 tons.

The Port's cranes can lift as much as 65 tons of containerized cargo.

The bamboos (Bambusoideae) are a subfamily of flowering perennial evergreen plants in the grass family Poaceae.

 

Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.

 

Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 88.9 Centimeters within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.

 

The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.

 

SYSTEMATICS AND TAXONOMY

The bamboos have long been considered the most primitive grasses, mostly because of the presence of bracteate, indeterminate inflorescences, "pseudospikelets", and flowers with three lodicules, six stamens, and three stigmas. Following more recent molecular phylogenetic research, many tribes and genera of grasses formerly included in Bambusoideae are now classified in other subfamilies, e.g. the Anomochlooideae, the Puelioideae, and the Ehrhartoideae. The subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae (bluegrasses and relatives).

 

The bamboos contains three clades classified as tribes, and these strongly correspond with geographic divisions, representing the New World herbaceous species (Olyreae), tropical woody bamboos (Bambuseae) and temperate woody bamboos (Arundinarieae). The woody bamboos do not form a monophyletic group; instead, the tropical woody and herbaceous bamboos are sister to the temperate woody bamboos. Altogether, there are more than 1,400 species in 115 genera.

DISTRIBUTION

Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. They occur across East Asia, from 50°N latitude in Sakhalin through to Northern Australia, and west to India and the Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the mid-Atlantic states south to Argentina and Chile, reaching their southernmost point at 47°S latitude. Continental Europe is not known to have any native species of bamboo.

 

Recently, some attempts have been made to grow bamboo on a commercial basis in the Great Lakes region of east-central Africa, especially in Rwanda. In the United States, several companies are growing, harvesting, and distributing species such as Phyllostachys nigra (Henon) and Phyllostachys edulis (Moso).

 

ECOLOGY

Bamboo is one of the fastest-growing plants on Earth, with reported growth rates of 250 cm in 24 hours. However, the growth rate is dependent on local soil and climatic conditions, as well as species, and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of 3–10 centimetre per day during the growing period. Primarily growing in regions of warmer climates during the late Cretaceous period, vast fields existed in what is now Asia. Some of the largest timber bamboo can grow over 30 m tall, and be as large as 15–20 cm in diameter. However, the size range for mature bamboo is species dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4.6–12 metres, depending on species. Anji County of China, known as the "Town of Bamboo", provides the optimal climate and soil conditions to grow, harvest, and process some of the most valued bamboo poles available worldwide.

 

Unlike all trees, individual bamboo stems, or culms, emerge from the ground at their full diameter and grow to their full height in a single growing season of three to four months. During these several months, each new shoot grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens. During the third year, the culm hardens further. The shoot is now considered a fully mature culm. Over the next 2–5 years (depending on species), fungus begins to form on the outside of the culm, which eventually penetrates and overcomes the culm. Around 5–8 years later (species and climate dependent), the fungal growths cause the culm to collapse and decay. This brief life means culms are ready for harvest and suitable for use in construction within about three to seven years. Individual bamboo culms do not get any taller or larger in diameter in subsequent years than they do in their first year, and they do not replace any growth lost from pruning or natural breakage. Bamboos have a wide range of hardiness depending on species and locale. Small or young specimens of an individual species will produce small culms initially. As the clump and its rhizome system mature, taller and larger culms will be produced each year until the plant approaches its particular species limits of height and diameter.

 

Many tropical bamboo species will die at or near freezing temperatures, while some of the hardier or so-called temperate bamboos can survive temperatures as low as −29 °C. Some of the hardiest bamboo species can be grown in places as cold as USDA Plant Hardiness Zones 5–6, although they typically will defoliate and may even lose all above-ground growth, yet the rhizomes will survive and send up shoots again the next spring. In milder climates, such as USDA Zone 8 and above, some hardy bamboo may remain fully leafed out year-round.

 

MASS FLOWERING

Most bamboo species flower infrequently. In fact, many bamboos only flower at intervals as long as 65 or 120 years. These taxa exhibit mass flowering (or gregarious flowering), with all plants in a particular cohort flowering over a several-year period. Any plant derived through clonal propagation from this cohort will also flower regardless of whether it has been planted in a different location. The longest mass flowering interval known is 130 years, and it is for the species Phyllostachys bambusoides (Sieb. & Zucc.). In this species, all plants of the same stock flower at the same time, regardless of differences in geographic locations or climatic conditions, and then the bamboo dies. The lack of environmental impact on the time of flowering indicates the presence of some sort of "alarm clock" in each cell of the plant which signals the diversion of all energy to flower production and the cessation of vegetative growth. This mechanism, as well as the evolutionary cause behind it, is still largely a mystery.

 

One hypothesis to explain the evolution of this semelparous mass flowering is the predator satiation hypothesis which argues that by fruiting at the same time, a population increases the survival rate of their seeds by flooding the area with fruit, so, even if predators eat their fill, seeds will still be left over. By having a flowering cycle longer than the lifespan of the rodent predators, bamboos can regulate animal populations by causing starvation during the period between flowering events. Thus the death of the adult clone is due to resource exhaustion, as it would be more effective for parent plants to devote all resources to creating a large seed crop than to hold back energy for their own regeneration.

 

Another, the fire cycle hypothesis, argues that periodic flowering followed by death of the adult plants has evolved as a mechanism to create disturbance in the habitat, thus providing the seedlings with a gap in which to grow. This argues that the dead culms create a large fuel load, and also a large target for lightning strikes, increasing the likelihood of wildfire. Because bamboos can be aggressive as early successional plants, the seedlings would be able to outstrip other plants and take over the space left by their parents.

 

However, both have been disputed for different reasons. The predator satiation hypothesis does not explain why the flowering cycle is 10 times longer than the lifespan of the local rodents, something not predicted. The bamboo fire cycle hypothesis is considered by a few scientists to be unreasonable; they argue[20] that fires only result from humans and there is no natural fire in India. This notion is considered wrong based on distribution of lightning strike data during the dry season throughout India. However, another argument against this is the lack of precedent for any living organism to harness something as unpredictable as lightning strikes to increase its chance of survival as part of natural evolutionary progress.

 

More recently, a mathematical explanation for the extreme length of the flowering cycles has been offered, involving both the stabilizing selection implied by the predator satiation hypothesis and others, and the fact that plants that flower at longer intervals tend to release more seeds. The hypothesis claims that bamboo flowering intervals grew by integer multiplication. A mutant bamboo plant flowering at a non-integer multiple of its population's flowering interval would release its seeds alone, and would not enjoy the benefits of collective flowering (such as protection from predators). On the other hand, a mutant bamboo plant flowering at an integer multiple of its population's flowering interval would release its seeds only during collective flowering events, and would release more seeds than the average plant in the population. It could therefore take over the population, establishing a flowering interval that is an integer multiple of the previous flowering interval. The hypothesis predicts that observed bamboo flowering intervals should factorize into small prime numbers.

 

The mass fruiting also has direct economic and ecological consequences, however. The huge increase in available fruit in the forests often causes a boom in rodent populations, leading to increases in disease and famine in nearby human populations. For example, devastating consequences occur when the Melocanna bambusoides population flowers and fruits once every 30–35 years around the Bay of Bengal. The death of the bamboo plants following their fruiting means the local people lose their building material, and the large increase in bamboo fruit leads to a rapid increase in rodent populations. As the number of rodents increases, they consume all available food, including grain fields and stored food, sometimes leading to famine. These rats can also carry dangerous diseases, such as typhus, typhoid, and bubonic plague, which can reach epidemic proportions as the rodents increase in number. The relationship between rat populations and bamboo flowering was examined in a 2009 Nova documentary "Rat Attack".

 

In any case, flowering produces masses of seeds, typically suspended from the ends of the branches. These seeds will give rise to a new generation of plants that may be identical in appearance to those that preceded the flowering, or they may produce new cultivars with different characteristics, such as the presence or absence of striping or other changes in coloration of the culms.

 

Several bamboo species are never known to set seed even when sporadically flowering has been reported. Bambusa vulgaris, Bambusa balcooa and Dendrocalamus stocksii are common examples of such bamboo.

 

AS ANIMAL DIET

Soft bamboo shoots, stems, and leaves are the major food source of the giant panda of China, the red panda of Nepal and the bamboo lemurs of Madagascar. Rats will eat the fruits as described above. Mountain gorillas of Africa also feed on bamboo, and have been documented consuming bamboo sap which was fermented and alcoholic; chimpanzees and elephants of the region also eat the stalks.

 

The larvae of the bamboo borer (the moth Omphisa fuscidentalis) of Laos, Myanmar, Thailand and Yunnan Province, China, feeds off the pulp of live bamboo. In turn, these caterpillars are considered a local delicacy.

 

CULTIVATION

COMMERCIAL TIMBER

Timber is harvested from both cultivated and wild stands, and some of the larger bamboos, particularly species in the genus Phyllostachys, are known as "timber bamboos".

 

HARVESTING

Bamboo used for construction purposes must be harvested when the culms reach their greatest strength and when sugar levels in the sap are at their lowest, as high sugar content increases the ease and rate of pest infestation.

 

Harvesting of bamboo is typically undertaken according to the following cycles:

 

1) Life cycle of the culm: As each individual culm goes through a 5– to 7-year life cycle, culms are ideally allowed to reach this level of maturity prior to full capacity harvesting. The clearing out or thinning of culms, particularly older decaying culms, helps to ensure adequate light and resources for new growth. Well-maintained clumps may have a productivity three to four times that of an unharvested wild clump. Consistent with the life cycle described above, bamboo is harvested from two to three years through to five to seven years, depending on the species.

 

2) Annual cycle: As all growth of new bamboo occurs during the wet season, disturbing the clump during this phase will potentially damage the upcoming crop. Also during this high rainfall period, sap levels are at their highest, and then diminish towards the dry season. Picking immediately prior to the wet/growth season may also damage new shoots. Hence, harvesting is best a few months prior to the start of the wet season.

 

3) Daily cycle: During the height of the day, photosynthesis is at its peak, producing the highest levels of sugar in sap, making this the least ideal time of day to harvest. Many traditional practitioners believe the best time to harvest is at dawn or dusk on a waning moon.

 

LEACHING

Leaching is the removal of sap after harvest. In many areas of the world, the sap levels in harvested bamboo are reduced either through leaching or postharvest photosynthesis.

 

EXEMPLES OF THIS PRACTICE INCLUDE:

Cut bamboo is raised clear of the ground and leaned against the rest of the clump for one to two weeks until leaves turn yellow to allow full consumption of sugars by the plant.

A similar method is undertaken, but with the base of the culm standing in fresh water, either in a large drum or stream to leach out sap.

Cut culms are immersed in a running stream and weighted down for three to four weeks.

Water is pumped through the freshly cut culms, forcing out the sap (this method is often used in conjunction with the injection of some form of treatment).

 

In the process of water leaching, the bamboo is dried slowly and evenly in the shade to avoid cracking in the outer skin of the bamboo, thereby reducing opportunities for pest infestation.

 

Durability of bamboo in construction is directly related to how well it is handled from the moment of planting through harvesting, transportation, storage, design, construction and maintenance. Bamboo harvested at the correct time of year and then exposed to ground contact or rain, will break down just as quickly as incorrectly harvested material.

 

ORNAMENTAL BAMBOOS

The two general patterns for the growth of bamboo are "clumping" (sympodial) and "running" (monopodial). Clumping bamboo species tend to spread slowly, as the growth pattern of the rhizomes is to simply expand the root mass gradually, similar to ornamental grasses. "Running" bamboos, on the other hand, need to be controlled during cultivation because of their potential for aggressive behavior. They spread mainly through their roots and/or rhizomes, which can spread widely underground and send up new culms to break through the surface. Running bamboo species are highly variable in their tendency to spread; this is related to both the species and the soil and climate conditions. Some can send out runners of several metres a year, while others can stay in the same general area for long periods. If neglected, over time they can cause problems by moving into adjacent areas.

 

Bamboos seldom and unpredictably flower, and the frequency of flowering varies greatly from species to species. Once flowering takes place, a plant will decline and often die entirely. Although there are always a few species of bamboo in flower at any given time, collectors desiring to grow specific bamboo typically obtain their plants as divisions of already-growing plants, rather than waiting for seeds to be produced.

 

Regular observations will indicate major growth directions and locations. Once the rhizomes are cut, they are typically removed; however, rhizomes take a number of months to mature, and an immature, severed rhizome will usually cease growing if left in-ground. If any bamboo shoots come up outside of the bamboo area afterwards, their presence indicates the precise location of the removed rhizome. The fibrous roots that radiate from the rhizomes do not produce more bamboo.

 

Bamboo growth is also controlled by surrounding the plant or grove with a physical barrier. Typically, concrete and specially rolled HDPE plastic are the materials used to create the barrier, which is placed in a 60– to 90-cm-deep ditch around the planting, and angled out at the top to direct the rhizomes to the surface. (This is only possible if the barrier is installed in a straight line.) If the containment area is small, this method can be detrimental to ornamental bamboo, as the bamboo within can become rootbound and start to display the signs of any unhealthy containerized plant. In addition, rhizomes can escape over the top, or beneath the barrier if it is not deep enough. Strong rhizomes and tools can penetrate plastic barriers, so care must be taken. In small areas, regular maintenance may be the best method for controlling the running bamboos. Barriers and edging are unnecessary for clump-forming bamboos, although these may eventually need to have portions removed if they become too large.

 

The ornamental plant sold in containers and marketed as "lucky bamboo" is actually an entirely unrelated plant, Dracaena sanderiana. It is a resilient member of the lily family that grows in the dark, tropical rainforests of Southeast Asia and Africa. Lucky bamboo has long been associated with the Eastern practice of feng shui and images of the plant widely available on the Web are often used to depict bamboo. On a similar note, Japanese knotweed is also sometimes mistaken for a bamboo, but it grows wild and is considered an invasive species. Phyllostachys species of bamboo are also considered invasive and illegal to sell or propagate in some areas of the US.

 

USES

CULINARY

Although the shoots (new culms that come out of the ground) of bamboo contain a toxin taxiphyllin (a cyanogenic glycoside) that produces cyanide in the gut, proper processing renders them edible. They are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh and canned versions. The golden bamboo lemur ingests many times the quantity of the taxiphyllin-containing bamboo that would kill a human.

 

The bamboo shoot in its fermented state forms an important ingredient in cuisines across the Himalayas. In Assam, India, for example, it is called khorisa. In Nepal, a delicacy popular across ethnic boundaries consists of bamboo shoots fermented with turmeric and oil, and cooked with potatoes into a dish that usually accompanies rice (alu tama (आलु तामा) in Nepali).

 

In Indonesia, they are sliced thin and then boiled with santan (thick coconut milk) and spices to make a dish called gulai rebung. Other recipes using bamboo shoots are sayur lodeh (mixed vegetables in coconut milk) and lun pia (sometimes written lumpia: fried wrapped bamboo shoots with vegetables). The shoots of some species contain toxins that need to be leached or boiled out before they can be eaten safely.

 

Pickled bamboo, used as a condiment, may also be made from the pith of the young shoots.

 

The sap of young stalks tapped during the rainy season may be fermented to make ulanzi (a sweet wine) or simply made into a soft drink. Bamboo leaves are also used as wrappers for steamed dumplings which usually contains glutinous rice and other ingredients.

 

Pickled bamboo shoots (Nepali:तामा tama) are cooked with black-eyed beans as a delicacy food in Nepal. Many Nepalese restaurant around the world serve this dish as aloo bodi tama. Fresh bamboo shoots are sliced and pickled with mustard seeds and turmeric and kept in glass jar in direct sunlight for the best taste. It is used alongside many dried beans in cooking during winter months. Baby shoots (Nepali: tusa) of a very different variety of bamboo (Nepali: निगालो Nigalo) native to Nepal is cooked as a curry in Hilly regions.

 

In Sambalpur, India, the tender shoots are grated into juliennes and fermented to prepare kardi. The name is derived from the Sanskrit word for bamboo shoot, karira. This fermented bamboo shoot is used in various culinary preparations, notably amil, a sour vegetable soup. It is also made into pancakes using rice flour as a binding agent. The shoots that have turned a little fibrous are fermented, dried, and ground to sand-sized particles to prepare a garnish known as hendua. It is also cooked with tender pumpkin leaves to make sag green leaves.

 

In Konkani cuisine, the tender shoots (kirlu) are grated and cooked with crushed jackfruit seeds to prepare 'kirla sukke'.

 

The empty hollow in the stalks of larger bamboo is often used to cook food in many Asian cultures. Soups are boiled and rice is cooked in the hollows of fresh stalks of bamboo directly over a flame. Similarly, steamed tea is sometimes rammed into bamboo hollows to produce compressed forms of Pu-erh tea. Cooking food in bamboo is said to give the food a subtle but distinctive taste.

 

In addition, bamboo is frequently used for cooking utensils within many cultures, and is used in the manufacture of chopsticks. In modern times, some see bamboo tools as an ecofriendly alternative to other manufactured utensils.

 

MEDICINE

Bamboo is used in Chinese medicine for treating infections and healing. In northern Indian state of Assam, the fermented bamboo paste known as khorisa is known locally as a folk remedy for the treatment of impotence, infertility, and menstrual pains.

 

CONSTRUCTION

Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.

 

In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.

 

Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong. In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support. In Japanese architecture, bamboo is used primarily as a supplemental and/or decorative element in buildings such as fencing, fountains, grates and gutters, largely due to the ready abundance of quality timber.

 

Various structural shapes may be made by training the bamboo to assume them as it grows. Squared sections of bamboo are created by compressing the growing stalk within a square form. Arches may similarly be created by forcing the bamboo's growth into the desired form, costing much less than it would to obtain the same shape with regular wood timber. More traditional forming methods, such as the application of heat and pressure, may also be used to curve or flatten the cut stalks.

 

Bamboo can be cut and laminated into sheets and planks. This process involves cutting stalks into thin strips, planing them flat, and boiling and drying the strips; they are then glued, pressed and finished. Long used in China and Japan, entrepreneurs started developing and selling laminated bamboo flooring in the West during the mid-1990s; products made from bamboo laminate, including flooring, cabinetry, furniture and even decorations, are currently surging in popularity, transitioning from the boutique market to mainstream providers such as Home Depot. The bamboo goods industry (which also includes small goods, fabric, etc.) is expected to be worth $25 billion by 2012. The quality of bamboo laminate varies among manufacturers and varies according to the maturity of the plant from which it was harvested (six years being considered the optimum); the sturdiest products fulfill their claims of being up to three times harder than oak hardwood while others may be softer than standard hardwood.

 

Bamboo intended for use in construction should be treated to resist insects and rot. The most common solution for this purpose is a mixture of borax and boric acid. Another process involves boiling cut bamboo to remove the starches that attract insects.

 

Bamboo has been used as reinforcement for concrete in those areas where it is plentiful, though dispute exists over its effectiveness in the various studies done on the subject. Bamboo does have the necessary strength to fulfil this function, but untreated bamboo will swell with water absorbed from the concrete, causing it to crack. Several procedures must be followed to overcome this shortcoming.

 

Several institutes, businesses, and universities are researching the use of bamboo as an ecological construction material. In the United States and France, it is possible to get houses made entirely of bamboo,[citation needed] which are earthquake- and cyclone-resistant and internationally certified. In Bali, Indonesia, an international K-12 school, the Green School, is constructed entirely of bamboo, for its beauty and advantages as a sustainable resource. There are three ISO standards for bamboo as a construction material.

 

In parts of India, bamboo is used for drying clothes indoors, both as a rod high up near the ceiling to hang clothes on, and as a stick wielded with acquired expert skill to hoist, spread, and to take down the clothes when dry. It is also commonly used to make ladders, which apart from their normal function, are also used for carrying bodies in funerals. In Maharashtra, the bamboo groves and forests are called Veluvana, the name velu for bamboo is most likely from Sanskrit, while vana means forest.

 

Furthermore, bamboo is also used to create flagpoles for saffron-coloured, Hindu religious flags, which can be seen fluttering across India, especially in Bihar and Uttar Pradesh, as well as in Guyana and Suriname in South America.

 

Bamboo was used for the structural members of the India pavilion at Expo 2010 in Shanghai. The pavilion is the world’s largest bamboo dome, about 34 m in diameter, with bamboo beams/members overlaid with a ferro-concrete slab, waterproofing, copper plate, solar PV panels, a small windmill, and live plants. A total of 30 km of bamboo was used. The dome is supported on 18-m-long steel piles and a series of steel ring beams. The bamboo was treated with borax and boric acid as a fire retardant and insecticide and bent in the required shape. The bamboo sections were joined with reinforcement bars and concrete mortar to achieve the necessary lengths.

 

TEXTILES

Since the fibers of bamboo are very short (less than 3 mm), they are not usually transformed into yarn by a natural process. The usual process by which textiles labeled as being made of bamboo are produced uses only rayon made from the fibers with heavy employment of chemicals. To accomplish this, the fibers are broken down with chemicals and extruded through mechanical spinnerets; the chemicals include lye, carbon disulfide and strong acids. Retailers have sold both end products as "bamboo fabric" to cash in on bamboo's current ecofriendly cachet; however, the Canadian Competition Bureau and the US Federal Trade Commission, as of mid-2009, are cracking down on the practice of labeling bamboo rayon as natural bamboo fabric. Under the guidelines of both agencies, these products must be labeled as rayon with the optional qualifier "from bamboo".

 

AS A WRITING SURFACE

Bamboo was in widespread use in early China as a medium for written documents. The earliest surviving examples of such documents, written in ink on string-bound bundles of bamboo strips (or "slips"), date from the fifth century BC during the Warring States period. However, references in earlier texts surviving on other media make it clear that some precursor of these Warring States period bamboo slips was in use as early as the late Shang period (from about 1250 BC).

 

Bamboo or wooden strips were the standard writing material during the Han dynasty, and excavated examples have been found in abundance. Subsequently, paper began to displace bamboo and wooden strips from mainstream uses, and by the fourth century AD, bamboo slips had been largely abandoned as a medium for writing in China. Several paper industries are surviving on bamboo forests. Ballarpur (Chandrapur, Maharstra) paper mills use bamboo for paper production.

 

Bamboo fiber has been used to make paper in China since early times. A high-quality, handmade paper is still produced in small quantities. Coarse bamboo paper is still used to make spirit money in many Chinese communities.

 

Bamboo pulps are mainly produced in China, Myanmar, Thailand and India, and are used in printing and writing papers. The most common bamboo species used for paper are Dendrocalamus asper and Bamboo bluemanea. It is also possible to make dissolving pulp from bamboo. The average fiber length is similar to hardwoods, but the properties of bamboo pulp are closer to softwood pulps due to it having a very broad fiber length distribution. With the help of molecular tools, it is now possible to distinguish the superior fiber-yielding species/varieties even at juvenile stages of their growth, which can help in unadulterated merchandise production.[

 

WEAPONS

Bamboo has often been used to construct weapons and is still incorporated in several Asian martial arts.

 

A bamboo staff, sometimes with one end sharpened, is used in the Tamil martial art of silambam, a word derived from a term meaning "hill bamboo".

Staves used in the Indian martial art of gatka are commonly made from bamboo, a material favoured for its light weight.

A bamboo sword called a shinai is used in the Japanese martial art of kendo.

Bamboo is used for crafting the bows, called yumi, and arrows used in the Japanese martial art kyudo.

Bamboo is sometimes used to craft the limbs of the longbow and recurve bow used in traditional archery, and to make superior weapons for bowhunting and target archery.

The first gunpowder-based weapons, such as the fire lance, were made of bamboo.

Bamboo was apparently used in East and South Asia as a means of torture.

 

OTHER USES

Bamboo has traditionally been used to make a wide range of everyday utensils, particularly in Japan, where archaeological excavations have uncovered bamboo baskets dating to the Late Jomon period (2000–1000 BC).

 

Bamboo has a long history of use in Asian furniture. Chinese bamboo furniture is a distinct style based on a millennia-long tradition.

 

Several manufacturers offer bamboo bicycles, surfboards, snowboards, and skateboards.

 

Due to its flexibility, bamboo is also used to make fishing rods. The split cane rod is especially prized for fly fishing. Bamboo has been traditionally used in Malaysia as a firecracker called a meriam buluh or bamboo cannon. Four-foot-long sections of bamboo are cut, and a mixture of water and calcium carbide are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang. Bamboo can be used in water desalination. A bamboo filter is used to remove the salt from seawater.

 

Food is cooked in East Timor in bamboo in fire. This is called Tukir.

 

Many minority groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, 6–7 metres long, laid together side by side to a width of about 1 metre. Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water. Bamboo is also used to make eating utensils such as chop sticks, trays, and tea scoops.

 

The Song Dynasty (960–1279 AD) Chinese scientist and polymath Shen Kuo (1031–1095) used the evidence of underground petrified bamboo found in the dry northern climate of Yan'an, Shanbei region, Shaanxi province to support his geological theory of gradual climate change.

 

SYMBOLISM AND CULTURE

Bamboo's long life makes it a Chinese symbol of uprightness, while in India it is a symbol of friendship. The rarity of its blossoming has led to the flowers' being regarded as a sign of impending famine. This may be due to rats feeding upon the profusion of flowers, then multiplying and destroying a large part of the local food supply. The most recent flowering began in May 2006 (see Mautam). Bamboo is said to bloom in this manner only about every 50 years (see 28–60 year examples in FAO: 'gregarious' species table).

 

In Chinese culture, the bamboo, plum blossom, orchid, and chrysanthemum (often known as méi lán zhú jú 梅兰竹菊) are collectively referred to as the Four Gentlemen. These four plants also represent the four seasons and, in Confucian ideology, four aspects of the junzi ("prince" or "noble one"). The pine (sōng 松), the bamboo (zhú 竹), and the plum blossom (méi 梅) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends of Winter" (岁寒三友 suìhán sānyǒu) in Chinese culture. The "Three Friends of Winter" is traditionally used as a system of ranking in Japan, for example in sushi sets or accommodations at a traditional ryokan. Pine (matsu 松) is of the first rank, bamboo (také 竹) is of second rank, and plum (ume 梅) is of the third.

 

The Bozo ethnic group of West Africa take their name from the Bambara phrase bo-so, which means "bamboo house". Bamboo is also the national plant of St. Lucia.

 

BAMBOO, NOBLE AND USEFUL

Bamboo, one of the "Four Gentlemen" (bamboo, orchid, plum blossom and chrysanthemum), plays such an important role in traditional Chinese culture that it is even regarded as a behavior model of the gentleman. As bamboo has features such as uprightness, tenacity, and hollow heart, people endow bamboo with integrity, elegance, and plainness, though it is not physically strong. Countless poems praising bamboo written by ancient Chinese poets are actually metaphorically about people who exhibited these characteristics. According to laws, an ancient poet, Bai Juyi (772–846), thought that to be a gentleman, a man does not need to be physically strong, but he must be mentally strong, upright, and perseverant. Just as a bamboo is hollow-hearted, he should open his heart to accept anything of benefit and never have arrogance or prejudice. Bamboo is not only a symbol of a gentleman, but also plays an important role in Buddhism, which was introduced into China in the first century. As canons of Buddhism forbids cruelty to animals, flesh and egg were not allowed in the diet. The tender bamboo shoot (sǔn筍 in Chinese) thus became a nutritious alternative. Preparation methods developed over thousands of years have come to incorporated into Asian cuisines, especially for monks. A Buddhist monk, Zan Ning, wrote a manual of the bamboo shoot called "Sǔn Pǔ筍譜" offering descriptions and recipes for many kinds of bamboo shoots. Bamboo shoot has always been a traditional dish on the Chinese dinner table, especially in southern China. In ancient times, those who could afford a big house with a yard would plant bamboo in their garden.

 

In Japan, a bamboo forest sometimes surrounds a Shinto shrine as part of a sacred barrier against evil. Many Buddhist temples also have bamboo groves.

 

Bamboo plays an important part of the culture of Vietnam. Bamboo symbolizes the spirit of Vovinam (a Vietnamese martial arts): cương nhu phối triển (coordination between hard and soft (martial arts)). Bamboo also symbolizes the Vietnamese hometown and Vietnamese soul: the gentlemanlike, straightforwardness, hard working, optimism, unity, and adaptability. A Vietnamese proverb says, "When the bamboo is old, the bamboo sprouts appear", the meaning being Vietnam will never be annihilated; if the previous generation dies, the children take their place. Therefore, the Vietnam nation and Vietnamese value will be maintained and developed eternally. Traditional Vietnamese villages are surrounded by thick bamboo hedges (lũy tre).

 

IN MYTHOLOGY

Several Asian cultures, including that of the Andaman Islands, believe humanity emerged from a bamboo stem.

 

In Philippine mythology, one of the more famous creation accounts tells of the first man, Malakás ("Strong"), and the first woman, Maganda ("Beautiful"), each emerged from one half of a split bamboo stem on an island formed after the battle between Sky and Ocean. In Malaysia, a similar story includes a man who dreams of a beautiful woman while sleeping under a bamboo plant; he wakes up and breaks the bamboo stem, discovering the woman inside. The Japanese folktale "Tale of the Bamboo Cutter" (Taketori Monogatari) tells of a princess from the Moon emerging from a shining bamboo section. Hawaiian bamboo ('ohe) is a kinolau or body form of the Polynesian creator god Kāne.

 

A bamboo cane is also the weapon of Vietnamese legendary hero, Saint Giong, who had grown up immediately and magically since the age of three because of his wish to liberate his land from Ân invaders. An ancient Vietnamese legend (The Hundred-knot Bamboo Tree) tells of a poor, young farmer who fell in love with his landlord's beautiful daughter. The farmer asked the landlord for his daughter's hand in marriage, but the proud landlord would not allow her to be bound in marriage to a poor farmer. The landlord decided to foil the marriage with an impossible deal; the farmer must bring him a "bamboo tree of 100 nodes". But Gautama Buddha (Bụt) appeared to the farmer and told him that such a tree could be made from 100 nodes from several different trees. Bụt gave to him four magic words to attach the many nodes of bamboo: Khắc nhập, khắc xuất, which means "joined together immediately, fell apart immediately". The triumphant farmer returned to the landlord and demanded his daughter. Curious to see such a long bamboo, the landlord was magically joined to the bamboo when he touched it, as the young farmer said the first two magic words. The story ends with the happy marriage of the farmer and the landlord's daughter after the landlord agreed to the marriage and asked to be separated from the bamboo.

 

In a Chinese legend, the Emperor Yao gave two of his daughters to the future Emperor Shun as a test for his potential to rule. Shun passed the test of being able to run his household with the two emperor's daughters as wives, and thus Yao made Shun his successor, bypassing his unworthy son. Later, Shun drowned in the Xiang River. The tears his two bereaved wives let fall upon the bamboos growing there explains the origin of spotted bamboo. The two women later became goddesses.

O Porto de Suape é um porto brasileiro localizado no estado de Pernambuco, entre os municípios de Ipojuca e Cabo de Santo Agostinho, na Região Metropolitana do Recife. Seu projeto foi baseado na integração porto-indústria a exemplo de países como França e Japão.

A construção do porto de Suape foi prevista para operarar produtos combustíveis e cereais a granel, substituindo o Porto do Recife. Em 7 de novembro de 1978, uma lei estadual criou a empresa Suape Complexo Industrial Portuário para administrar o desenvolvimento das obras, hoje o porto é um dos maiores do Brasil; administrado pelo Governo de Pernambuco.

Sua área de influência abrange todo o estado de Pernambuco e parte dos estados de Alagoas e da Paraíba. O porto tem acesso rodoviário pela PE-060 e pela AL-101, na divisa de Pernambuco e Alagoas. É considerado o mais tecnologicamente avançado do Brasil.

Suape opera navios nos 365 dias do ano, sem restrições de horário de marés. Para auxiliar as operações de acostagem dos navios, o Porto dispõe de um sistema de monitoração de atracação de navios a laser, que possibilita um controle efetivo e seguro, oferecendo ao prático condições técnicas nos padrões dos portos mais importantes do mundo.

O Porto já movimenta mais de 5 milhões de toneladas de carga por ano, destacando-se, entre elas, os granéis líquidos (derivados de petróleo, produtos químicos, álcoois, óleos vegetais etc), com mais de 80% da movimentação, e a carga conteinerizada. O Porto pode atender a navios de até 170.000 tpb e calado operacional de 14,50 m. Com 27 km² de retroporto, seus portos externo e interno oferecem as condições necessárias para atendimento de navios de grande porte.

A movimentação portuária cresce em ritmo acelerado e consolida Suape como um porto concentrador e distribuidor de cargas. Em 2011, a movimentação de cargas ultrapassou os 11 milhões de toneladas e a de contêineres foi maior que 400 mil TEUs, o que representa um crescimento de 25% e 33%, respectivamente, em relação ao ano anterior.

A sua concepção de porto-indústria oferece condições ideais para a instalação de empreendimentos nos mais diversos segmentos. Suape conta com uma infraestrutura terrestre própria, em permanente desenvolvimento e modernização, com ferrovias e rodovias. O porto interno, recentemente, ganhou novos berços e, além disso, o Complexo ainda conta com fornecimento de gás natural, energia elétrica, água bruta e água tratada. Situado na Região Metropolitana do Recife, possui área de 13.500 hectares, distribuída em zonas Portuária, Industrial, Administrativa e Serviços, de Preservação Ecológica e de Preservação Cultural.

Já são mais de 100 empresas em operação, responsáveis por mais de 25 mil empregos diretos, e outras 50 em implantação. Entre elas, indústrias de produtos químicos, metal-mecânica, naval e logística, que vão fortalecer os polos de geração de energia, granéis líquidos e gases, alimentos e energia eólica, além de abrir espaços em outros segmentos como metal-mecânico, grãos e logística.

The bamboos (Bambusoideae) are a subfamily of flowering perennial evergreen plants in the grass family Poaceae.

 

Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.

 

Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 88.9 Centimeters within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.

 

The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.

 

SYSTEMATICS AND TAXONOMY

The bamboos have long been considered the most primitive grasses, mostly because of the presence of bracteate, indeterminate inflorescences, "pseudospikelets", and flowers with three lodicules, six stamens, and three stigmas. Following more recent molecular phylogenetic research, many tribes and genera of grasses formerly included in Bambusoideae are now classified in other subfamilies, e.g. the Anomochlooideae, the Puelioideae, and the Ehrhartoideae. The subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae (bluegrasses and relatives).

 

The bamboos contains three clades classified as tribes, and these strongly correspond with geographic divisions, representing the New World herbaceous species (Olyreae), tropical woody bamboos (Bambuseae) and temperate woody bamboos (Arundinarieae). The woody bamboos do not form a monophyletic group; instead, the tropical woody and herbaceous bamboos are sister to the temperate woody bamboos. Altogether, there are more than 1,400 species in 115 genera.

 

Tribe Olyreae (herbaceous bamboos)

Tribe Bambuseae (tropical woody bamboos)

Tribe Arundinarieae (temperate woody bamboos)

 

DISTRIBUTION

Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. They occur across East Asia, from 50°N latitude in Sakhalin through to Northern Australia, and west to India and the Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the mid-Atlantic states south to Argentina and Chile, reaching their southernmost point at 47°S latitude. Continental Europe is not known to have any native species of bamboo.

 

Recently, some attempts have been made to grow bamboo on a commercial basis in the Great Lakes region of east-central Africa, especially in Rwanda. In the United States, several companies are growing, harvesting, and distributing species such as Phyllostachys nigra (Henon) and Phyllostachys edulis (Moso).

 

ECOLOGY

Bamboo is one of the fastest-growing plants on Earth, with reported growth rates of 250 cm in 24 hours. However, the growth rate is dependent on local soil and climatic conditions, as well as species, and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of 3–10 centimetre per day during the growing period. Primarily growing in regions of warmer climates during the late Cretaceous period, vast fields existed in what is now Asia. Some of the largest timber bamboo can grow over 30 m tall, and be as large as 15–20 cm in diameter. However, the size range for mature bamboo is species dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4.6–12 metres, depending on species. Anji County of China, known as the "Town of Bamboo", provides the optimal climate and soil conditions to grow, harvest, and process some of the most valued bamboo poles available worldwide.

 

Unlike all trees, individual bamboo stems, or culms, emerge from the ground at their full diameter and grow to their full height in a single growing season of three to four months. During these several months, each new shoot grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens. During the third year, the culm hardens further. The shoot is now considered a fully mature culm. Over the next 2–5 years (depending on species), fungus begins to form on the outside of the culm, which eventually penetrates and overcomes the culm. Around 5–8 years later (species and climate dependent), the fungal growths cause the culm to collapse and decay. This brief life means culms are ready for harvest and suitable for use in construction within about three to seven years. Individual bamboo culms do not get any taller or larger in diameter in subsequent years than they do in their first year, and they do not replace any growth lost from pruning or natural breakage. Bamboos have a wide range of hardiness depending on species and locale. Small or young specimens of an individual species will produce small culms initially. As the clump and its rhizome system mature, taller and larger culms will be produced each year until the plant approaches its particular species limits of height and diameter.

 

Many tropical bamboo species will die at or near freezing temperatures, while some of the hardier or so-called temperate bamboos can survive temperatures as low as −29 °C. Some of the hardiest bamboo species can be grown in places as cold as USDA Plant Hardiness Zones 5–6, although they typically will defoliate and may even lose all above-ground growth, yet the rhizomes will survive and send up shoots again the next spring. In milder climates, such as USDA Zone 8 and above, some hardy bamboo may remain fully leafed out year-round.

 

MASS FLOWERING

Most bamboo species flower infrequently. In fact, many bamboos only flower at intervals as long as 65 or 120 years. These taxa exhibit mass flowering (or gregarious flowering), with all plants in a particular cohort flowering over a several-year period. Any plant derived through clonal propagation from this cohort will also flower regardless of whether it has been planted in a different location. The longest mass flowering interval known is 130 years, and it is for the species Phyllostachys bambusoides (Sieb. & Zucc.). In this species, all plants of the same stock flower at the same time, regardless of differences in geographic locations or climatic conditions, and then the bamboo dies. The lack of environmental impact on the time of flowering indicates the presence of some sort of "alarm clock" in each cell of the plant which signals the diversion of all energy to flower production and the cessation of vegetative growth. This mechanism, as well as the evolutionary cause behind it, is still largely a mystery.

 

One hypothesis to explain the evolution of this semelparous mass flowering is the predator satiation hypothesis which argues that by fruiting at the same time, a population increases the survival rate of their seeds by flooding the area with fruit, so, even if predators eat their fill, seeds will still be left over. By having a flowering cycle longer than the lifespan of the rodent predators, bamboos can regulate animal populations by causing starvation during the period between flowering events. Thus the death of the adult clone is due to resource exhaustion, as it would be more effective for parent plants to devote all resources to creating a large seed crop than to hold back energy for their own regeneration.

 

Another, the fire cycle hypothesis, argues that periodic flowering followed by death of the adult plants has evolved as a mechanism to create disturbance in the habitat, thus providing the seedlings with a gap in which to grow. This argues that the dead culms create a large fuel load, and also a large target for lightning strikes, increasing the likelihood of wildfire. Because bamboos can be aggressive as early successional plants, the seedlings would be able to outstrip other plants and take over the space left by their parents.

 

However, both have been disputed for different reasons. The predator satiation hypothesis does not explain why the flowering cycle is 10 times longer than the lifespan of the local rodents, something not predicted. The bamboo fire cycle hypothesis is considered by a few scientists to be unreasonable; they argue[20] that fires only result from humans and there is no natural fire in India. This notion is considered wrong based on distribution of lightning strike data during the dry season throughout India. However, another argument against this is the lack of precedent for any living organism to harness something as unpredictable as lightning strikes to increase its chance of survival as part of natural evolutionary progress.

 

More recently, a mathematical explanation for the extreme length of the flowering cycles has been offered, involving both the stabilizing selection implied by the predator satiation hypothesis and others, and the fact that plants that flower at longer intervals tend to release more seeds. The hypothesis claims that bamboo flowering intervals grew by integer multiplication. A mutant bamboo plant flowering at a non-integer multiple of its population's flowering interval would release its seeds alone, and would not enjoy the benefits of collective flowering (such as protection from predators). On the other hand, a mutant bamboo plant flowering at an integer multiple of its population's flowering interval would release its seeds only during collective flowering events, and would release more seeds than the average plant in the population. It could therefore take over the population, establishing a flowering interval that is an integer multiple of the previous flowering interval. The hypothesis predicts that observed bamboo flowering intervals should factorize into small prime numbers.

 

The mass fruiting also has direct economic and ecological consequences, however. The huge increase in available fruit in the forests often causes a boom in rodent populations, leading to increases in disease and famine in nearby human populations. For example, devastating consequences occur when the Melocanna bambusoides population flowers and fruits once every 30–35 years around the Bay of Bengal. The death of the bamboo plants following their fruiting means the local people lose their building material, and the large increase in bamboo fruit leads to a rapid increase in rodent populations. As the number of rodents increases, they consume all available food, including grain fields and stored food, sometimes leading to famine. These rats can also carry dangerous diseases, such as typhus, typhoid, and bubonic plague, which can reach epidemic proportions as the rodents increase in number. The relationship between rat populations and bamboo flowering was examined in a 2009 Nova documentary "Rat Attack".

 

In any case, flowering produces masses of seeds, typically suspended from the ends of the branches. These seeds will give rise to a new generation of plants that may be identical in appearance to those that preceded the flowering, or they may produce new cultivars with different characteristics, such as the presence or absence of striping or other changes in coloration of the culms.

 

Several bamboo species are never known to set seed even when sporadically flowering has been reported. Bambusa vulgaris, Bambusa balcooa and Dendrocalamus stocksii are common examples of such bamboo.

 

AS ANIMAL DIET

Soft bamboo shoots, stems, and leaves are the major food source of the giant panda of China, the red panda of Nepal and the bamboo lemurs of Madagascar. Rats will eat the fruits as described above. Mountain gorillas of Africa also feed on bamboo, and have been documented consuming bamboo sap which was fermented and alcoholic; chimpanzees and elephants of the region also eat the stalks.

 

The larvae of the bamboo borer (the moth Omphisa fuscidentalis) of Laos, Myanmar, Thailand and Yunnan Province, China, feeds off the pulp of live bamboo. In turn, these caterpillars are considered a local delicacy.

 

CULTIVATION

COMMERCIAL TIMBER

Timber is harvested from both cultivated and wild stands, and some of the larger bamboos, particularly species in the genus Phyllostachys, are known as "timber bamboos".

 

HARVESTING

Bamboo used for construction purposes must be harvested when the culms reach their greatest strength and when sugar levels in the sap are at their lowest, as high sugar content increases the ease and rate of pest infestation.

 

Harvesting of bamboo is typically undertaken according to the following cycles:

 

1) Life cycle of the culm: As each individual culm goes through a 5– to 7-year life cycle, culms are ideally allowed to reach this level of maturity prior to full capacity harvesting. The clearing out or thinning of culms, particularly older decaying culms, helps to ensure adequate light and resources for new growth. Well-maintained clumps may have a productivity three to four times that of an unharvested wild clump. Consistent with the life cycle described above, bamboo is harvested from two to three years through to five to seven years, depending on the species.

 

2) Annual cycle: As all growth of new bamboo occurs during the wet season, disturbing the clump during this phase will potentially damage the upcoming crop. Also during this high rainfall period, sap levels are at their highest, and then diminish towards the dry season. Picking immediately prior to the wet/growth season may also damage new shoots. Hence, harvesting is best a few months prior to the start of the wet season.

 

3) Daily cycle: During the height of the day, photosynthesis is at its peak, producing the highest levels of sugar in sap, making this the least ideal time of day to harvest. Many traditional practitioners believe the best time to harvest is at dawn or dusk on a waning moon.

 

LEACHING

Leaching is the removal of sap after harvest. In many areas of the world, the sap levels in harvested bamboo are reduced either through leaching or postharvest photosynthesis.

 

EXEMPLES OF THIS PRACTICE INCLUDE:

Cut bamboo is raised clear of the ground and leaned against the rest of the clump for one to two weeks until leaves turn yellow to allow full consumption of sugars by the plant.

A similar method is undertaken, but with the base of the culm standing in fresh water, either in a large drum or stream to leach out sap.

Cut culms are immersed in a running stream and weighted down for three to four weeks.

Water is pumped through the freshly cut culms, forcing out the sap (this method is often used in conjunction with the injection of some form of treatment).

 

In the process of water leaching, the bamboo is dried slowly and evenly in the shade to avoid cracking in the outer skin of the bamboo, thereby reducing opportunities for pest infestation.

 

Durability of bamboo in construction is directly related to how well it is handled from the moment of planting through harvesting, transportation, storage, design, construction and maintenance. Bamboo harvested at the correct time of year and then exposed to ground contact or rain, will break down just as quickly as incorrectly harvested material.

 

ORNAMENTAL BAMBOOS

The two general patterns for the growth of bamboo are "clumping" (sympodial) and "running" (monopodial). Clumping bamboo species tend to spread slowly, as the growth pattern of the rhizomes is to simply expand the root mass gradually, similar to ornamental grasses. "Running" bamboos, on the other hand, need to be controlled during cultivation because of their potential for aggressive behavior. They spread mainly through their roots and/or rhizomes, which can spread widely underground and send up new culms to break through the surface. Running bamboo species are highly variable in their tendency to spread; this is related to both the species and the soil and climate conditions. Some can send out runners of several metres a year, while others can stay in the same general area for long periods. If neglected, over time they can cause problems by moving into adjacent areas.

 

Bamboos seldom and unpredictably flower, and the frequency of flowering varies greatly from species to species. Once flowering takes place, a plant will decline and often die entirely. Although there are always a few species of bamboo in flower at any given time, collectors desiring to grow specific bamboo typically obtain their plants as divisions of already-growing plants, rather than waiting for seeds to be produced.

 

Regular observations will indicate major growth directions and locations. Once the rhizomes are cut, they are typically removed; however, rhizomes take a number of months to mature, and an immature, severed rhizome will usually cease growing if left in-ground. If any bamboo shoots come up outside of the bamboo area afterwards, their presence indicates the precise location of the removed rhizome. The fibrous roots that radiate from the rhizomes do not produce more bamboo.

 

Bamboo growth is also controlled by surrounding the plant or grove with a physical barrier. Typically, concrete and specially rolled HDPE plastic are the materials used to create the barrier, which is placed in a 60– to 90-cm-deep ditch around the planting, and angled out at the top to direct the rhizomes to the surface. (This is only possible if the barrier is installed in a straight line.) If the containment area is small, this method can be detrimental to ornamental bamboo, as the bamboo within can become rootbound and start to display the signs of any unhealthy containerized plant. In addition, rhizomes can escape over the top, or beneath the barrier if it is not deep enough. Strong rhizomes and tools can penetrate plastic barriers, so care must be taken. In small areas, regular maintenance may be the best method for controlling the running bamboos. Barriers and edging are unnecessary for clump-forming bamboos, although these may eventually need to have portions removed if they become too large.

 

The ornamental plant sold in containers and marketed as "lucky bamboo" is actually an entirely unrelated plant, Dracaena sanderiana. It is a resilient member of the lily family that grows in the dark, tropical rainforests of Southeast Asia and Africa. Lucky bamboo has long been associated with the Eastern practice of feng shui and images of the plant widely available on the Web are often used to depict bamboo. On a similar note, Japanese knotweed is also sometimes mistaken for a bamboo, but it grows wild and is considered an invasive species. Phyllostachys species of bamboo are also considered invasive and illegal to sell or propagate in some areas of the US.

 

USES

CULINARY

Although the shoots (new culms that come out of the ground) of bamboo contain a toxin taxiphyllin (a cyanogenic glycoside) that produces cyanide in the gut, proper processing renders them edible. They are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh and canned versions. The golden bamboo lemur ingests many times the quantity of the taxiphyllin-containing bamboo that would kill a human.

 

The bamboo shoot in its fermented state forms an important ingredient in cuisines across the Himalayas. In Assam, India, for example, it is called khorisa. In Nepal, a delicacy popular across ethnic boundaries consists of bamboo shoots fermented with turmeric and oil, and cooked with potatoes into a dish that usually accompanies rice (alu tama (आलु तामा) in Nepali).

 

In Indonesia, they are sliced thin and then boiled with santan (thick coconut milk) and spices to make a dish called gulai rebung. Other recipes using bamboo shoots are sayur lodeh (mixed vegetables in coconut milk) and lun pia (sometimes written lumpia: fried wrapped bamboo shoots with vegetables). The shoots of some species contain toxins that need to be leached or boiled out before they can be eaten safely.

 

Pickled bamboo, used as a condiment, may also be made from the pith of the young shoots.

 

The sap of young stalks tapped during the rainy season may be fermented to make ulanzi (a sweet wine) or simply made into a soft drink. Bamboo leaves are also used as wrappers for steamed dumplings which usually contains glutinous rice and other ingredients.

 

Pickled bamboo shoots (Nepali:तामा tama) are cooked with black-eyed beans as a delicacy food in Nepal. Many Nepalese restaurant around the world serve this dish as aloo bodi tama. Fresh bamboo shoots are sliced and pickled with mustard seeds and turmeric and kept in glass jar in direct sunlight for the best taste. It is used alongside many dried beans in cooking during winter months. Baby shoots (Nepali: tusa) of a very different variety of bamboo (Nepali: निगालो Nigalo) native to Nepal is cooked as a curry in Hilly regions.

 

In Sambalpur, India, the tender shoots are grated into juliennes and fermented to prepare kardi. The name is derived from the Sanskrit word for bamboo shoot, karira. This fermented bamboo shoot is used in various culinary preparations, notably amil, a sour vegetable soup. It is also made into pancakes using rice flour as a binding agent. The shoots that have turned a little fibrous are fermented, dried, and ground to sand-sized particles to prepare a garnish known as hendua. It is also cooked with tender pumpkin leaves to make sag green leaves.

 

In Konkani cuisine, the tender shoots (kirlu) are grated and cooked with crushed jackfruit seeds to prepare 'kirla sukke'.

 

The empty hollow in the stalks of larger bamboo is often used to cook food in many Asian cultures. Soups are boiled and rice is cooked in the hollows of fresh stalks of bamboo directly over a flame. Similarly, steamed tea is sometimes rammed into bamboo hollows to produce compressed forms of Pu-erh tea. Cooking food in bamboo is said to give the food a subtle but distinctive taste.

 

In addition, bamboo is frequently used for cooking utensils within many cultures, and is used in the manufacture of chopsticks. In modern times, some see bamboo tools as an ecofriendly alternative to other manufactured utensils.

 

MEDICINE

Bamboo is used in Chinese medicine for treating infections and healing. In northern Indian state of Assam, the fermented bamboo paste known as khorisa is known locally as a folk remedy for the treatment of impotence, infertility, and menstrual pains.

 

CONSTRUCTION

Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.

 

In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.

 

Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong. In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support. In Japanese architecture, bamboo is used primarily as a supplemental and/or decorative element in buildings such as fencing, fountains, grates and gutters, largely due to the ready abundance of quality timber.

 

Various structural shapes may be made by training the bamboo to assume them as it grows. Squared sections of bamboo are created by compressing the growing stalk within a square form. Arches may similarly be created by forcing the bamboo's growth into the desired form, costing much less than it would to obtain the same shape with regular wood timber. More traditional forming methods, such as the application of heat and pressure, may also be used to curve or flatten the cut stalks.

 

Bamboo can be cut and laminated into sheets and planks. This process involves cutting stalks into thin strips, planing them flat, and boiling and drying the strips; they are then glued, pressed and finished. Long used in China and Japan, entrepreneurs started developing and selling laminated bamboo flooring in the West during the mid-1990s; products made from bamboo laminate, including flooring, cabinetry, furniture and even decorations, are currently surging in popularity, transitioning from the boutique market to mainstream providers such as Home Depot. The bamboo goods industry (which also includes small goods, fabric, etc.) is expected to be worth $25 billion by 2012. The quality of bamboo laminate varies among manufacturers and varies according to the maturity of the plant from which it was harvested (six years being considered the optimum); the sturdiest products fulfill their claims of being up to three times harder than oak hardwood while others may be softer than standard hardwood.

 

Bamboo intended for use in construction should be treated to resist insects and rot. The most common solution for this purpose is a mixture of borax and boric acid. Another process involves boiling cut bamboo to remove the starches that attract insects.

 

Bamboo has been used as reinforcement for concrete in those areas where it is plentiful, though dispute exists over its effectiveness in the various studies done on the subject. Bamboo does have the necessary strength to fulfil this function, but untreated bamboo will swell with water absorbed from the concrete, causing it to crack. Several procedures must be followed to overcome this shortcoming.

 

Several institutes, businesses, and universities are researching the use of bamboo as an ecological construction material. In the United States and France, it is possible to get houses made entirely of bamboo,[citation needed] which are earthquake- and cyclone-resistant and internationally certified. In Bali, Indonesia, an international K-12 school, the Green School, is constructed entirely of bamboo, for its beauty and advantages as a sustainable resource. There are three ISO standards for bamboo as a construction material.

 

In parts of India, bamboo is used for drying clothes indoors, both as a rod high up near the ceiling to hang clothes on, and as a stick wielded with acquired expert skill to hoist, spread, and to take down the clothes when dry. It is also commonly used to make ladders, which apart from their normal function, are also used for carrying bodies in funerals. In Maharashtra, the bamboo groves and forests are called Veluvana, the name velu for bamboo is most likely from Sanskrit, while vana means forest.

 

Furthermore, bamboo is also used to create flagpoles for saffron-coloured, Hindu religious flags, which can be seen fluttering across India, especially in Bihar and Uttar Pradesh, as well as in Guyana and Suriname in South America.

 

Bamboo was used for the structural members of the India pavilion at Expo 2010 in Shanghai. The pavilion is the world’s largest bamboo dome, about 34 m in diameter, with bamboo beams/members overlaid with a ferro-concrete slab, waterproofing, copper plate, solar PV panels, a small windmill, and live plants. A total of 30 km of bamboo was used. The dome is supported on 18-m-long steel piles and a series of steel ring beams. The bamboo was treated with borax and boric acid as a fire retardant and insecticide and bent in the required shape. The bamboo sections were joined with reinforcement bars and concrete mortar to achieve the necessary lengths.

 

TEXTILES

Since the fibers of bamboo are very short (less than 3 mm), they are not usually transformed into yarn by a natural process. The usual process by which textiles labeled as being made of bamboo are produced uses only rayon made from the fibers with heavy employment of chemicals. To accomplish this, the fibers are broken down with chemicals and extruded through mechanical spinnerets; the chemicals include lye, carbon disulfide and strong acids. Retailers have sold both end products as "bamboo fabric" to cash in on bamboo's current ecofriendly cachet; however, the Canadian Competition Bureau and the US Federal Trade Commission, as of mid-2009, are cracking down on the practice of labeling bamboo rayon as natural bamboo fabric. Under the guidelines of both agencies, these products must be labeled as rayon with the optional qualifier "from bamboo".

Bamboo was in widespread use in early China as a medium for written documents. The earliest surviving examples of such documents, written in ink on string-bound bundles of bamboo strips (or "slips"), date from the fifth century BC during the Warring States period. However, references in earlier texts surviving on other media make it clear that some precursor of these Warring States period bamboo slips was in use as early as the late Shang period (from about 1250 BC).

 

Bamboo or wooden strips were the standard writing material during the Han dynasty, and excavated examples have been found in abundance. Subsequently, paper began to displace bamboo and wooden strips from mainstream uses, and by the fourth century AD, bamboo slips had been largely abandoned as a medium for writing in China. Several paper industries are surviving on bamboo forests. Ballarpur (Chandrapur, Maharstra) paper mills use bamboo for paper production.

 

Bamboo fiber has been used to make paper in China since early times. A high-quality, handmade paper is still produced in small quantities. Coarse bamboo paper is still used to make spirit money in many Chinese communities.

 

Bamboo pulps are mainly produced in China, Myanmar, Thailand and India, and are used in printing and writing papers. The most common bamboo species used for paper are Dendrocalamus asper and Bamboo bluemanea. It is also possible to make dissolving pulp from bamboo. The average fiber length is similar to hardwoods, but the properties of bamboo pulp are closer to softwood pulps due to it having a very broad fiber length distribution. With the help of molecular tools, it is now possible to distinguish the superior fiber-yielding species/varieties even at juvenile stages of their growth, which can help in unadulterated merchandise production.[

 

WEAPONS

Bamboo has often been used to construct weapons and is still incorporated in several Asian martial arts.

 

A bamboo staff, sometimes with one end sharpened, is used in the Tamil martial art of silambam, a word derived from a term meaning "hill bamboo".

Staves used in the Indian martial art of gatka are commonly made from bamboo, a material favoured for its light weight.

A bamboo sword called a shinai is used in the Japanese martial art of kendo.

Bamboo is used for crafting the bows, called yumi, and arrows used in the Japanese martial art kyudo.

Bamboo is sometimes used to craft the limbs of the longbow and recurve bow used in traditional archery, and to make superior weapons for bowhunting and target archery.

The first gunpowder-based weapons, such as the fire lance, were made of bamboo.

Bamboo was apparently used in East and South Asia as a means of torture.

 

OTHER USES

Bamboo has traditionally been used to make a wide range of everyday utensils, particularly in Japan, where archaeological excavations have uncovered bamboo baskets dating to the Late Jomon period (2000–1000 BC).

 

Bamboo has a long history of use in Asian furniture. Chinese bamboo furniture is a distinct style based on a millennia-long tradition.

 

Several manufacturers offer bamboo bicycles, surfboards, snowboards, and skateboards.

 

Due to its flexibility, bamboo is also used to make fishing rods. The split cane rod is especially prized for fly fishing. Bamboo has been traditionally used in Malaysia as a firecracker called a meriam buluh or bamboo cannon. Four-foot-long sections of bamboo are cut, and a mixture of water and calcium carbide are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang. Bamboo can be used in water desalination. A bamboo filter is used to remove the salt from seawater.

 

Food is cooked in East Timor in bamboo in fire. This is called Tukir.

 

Many minority groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, 6–7 metres long, laid together side by side to a width of about 1 metre. Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water. Bamboo is also used to make eating utensils such as chop sticks, trays, and tea scoops.

 

The Song Dynasty (960–1279 AD) Chinese scientist and polymath Shen Kuo (1031–1095) used the evidence of underground petrified bamboo found in the dry northern climate of Yan'an, Shanbei region, Shaanxi province to support his geological theory of gradual climate change.

 

SYMBOLISM AND CULTURE

Bamboo's long life makes it a Chinese symbol of uprightness, while in India it is a symbol of friendship. The rarity of its blossoming has led to the flowers' being regarded as a sign of impending famine. This may be due to rats feeding upon the profusion of flowers, then multiplying and destroying a large part of the local food supply. The most recent flowering began in May 2006 (see Mautam). Bamboo is said to bloom in this manner only about every 50 years (see 28–60 year examples in FAO: 'gregarious' species table).

 

In Chinese culture, the bamboo, plum blossom, orchid, and chrysanthemum (often known as méi lán zhú jú 梅兰竹菊) are collectively referred to as the Four Gentlemen. These four plants also represent the four seasons and, in Confucian ideology, four aspects of the junzi ("prince" or "noble one"). The pine (sōng 松), the bamboo (zhú 竹), and the plum blossom (méi 梅) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends of Winter" (岁寒三友 suìhán sānyǒu) in Chinese culture. The "Three Friends of Winter" is traditionally used as a system of ranking in Japan, for example in sushi sets or accommodations at a traditional ryokan. Pine (matsu 松) is of the first rank, bamboo (také 竹) is of second rank, and plum (ume 梅) is of the third.

 

The Bozo ethnic group of West Africa take their name from the Bambara phrase bo-so, which means "bamboo house". Bamboo is also the national plant of St. Lucia.

 

BAMBOO, NOBLE AND USEFUL

Bamboo, one of the "Four Gentlemen" (bamboo, orchid, plum blossom and chrysanthemum), plays such an important role in traditional Chinese culture that it is even regarded as a behavior model of the gentleman. As bamboo has features such as uprightness, tenacity, and hollow heart, people endow bamboo with integrity, elegance, and plainness, though it is not physically strong. Countless poems praising bamboo written by ancient Chinese poets are actually metaphorically about people who exhibited these characteristics. According to laws, an ancient poet, Bai Juyi (772–846), thought that to be a gentleman, a man does not need to be physically strong, but he must be mentally strong, upright, and perseverant. Just as a bamboo is hollow-hearted, he should open his heart to accept anything of benefit and never have arrogance or prejudice. Bamboo is not only a symbol of a gentleman, but also plays an important role in Buddhism, which was introduced into China in the first century. As canons of Buddhism forbids cruelty to animals, flesh and egg were not allowed in the diet. The tender bamboo shoot (sǔn筍 in Chinese) thus became a nutritious alternative. Preparation methods developed over thousands of years have come to incorporated into Asian cuisines, especially for monks. A Buddhist monk, Zan Ning, wrote a manual of the bamboo shoot called "Sǔn Pǔ筍譜" offering descriptions and recipes for many kinds of bamboo shoots. Bamboo shoot has always been a traditional dish on the Chinese dinner table, especially in southern China. In ancient times, those who could afford a big house with a yard would plant bamboo in their garden.

 

In Japan, a bamboo forest sometimes surrounds a Shinto shrine as part of a sacred barrier against evil. Many Buddhist temples also have bamboo groves.

 

Bamboo plays an important part of the culture of Vietnam. Bamboo symbolizes the spirit of Vovinam (a Vietnamese martial arts): cương nhu phối triển (coordination between hard and soft (martial arts)). Bamboo also symbolizes the Vietnamese hometown and Vietnamese soul: the gentlemanlike, straightforwardness, hard working, optimism, unity, and adaptability. A Vietnamese proverb says, "When the bamboo is old, the bamboo sprouts appear", the meaning being Vietnam will never be annihilated; if the previous generation dies, the children take their place. Therefore, the Vietnam nation and Vietnamese value will be maintained and developed eternally. Traditional Vietnamese villages are surrounded by thick bamboo hedges (lũy tre).

 

IN MYTHOLOGY

Several Asian cultures, including that of the Andaman Islands, believe humanity emerged from a bamboo stem.

 

In Philippine mythology, one of the more famous creation accounts tells of the first man, Malakás ("Strong"), and the first woman, Maganda ("Beautiful"), each emerged from one half of a split bamboo stem on an island formed after the battle between Sky and Ocean. In Malaysia, a similar story includes a man who dreams of a beautiful woman while sleeping under a bamboo plant; he wakes up and breaks the bamboo stem, discovering the woman inside. The Japanese folktale "Tale of the Bamboo Cutter" (Taketori Monogatari) tells of a princess from the Moon emerging from a shining bamboo section. Hawaiian bamboo ('ohe) is a kinolau or body form of the Polynesian creator god Kāne.

 

A bamboo cane is also the weapon of Vietnamese legendary hero, Saint Giong, who had grown up immediately and magically since the age of three because of his wish to liberate his land from Ân invaders. An ancient Vietnamese legend (The Hundred-knot Bamboo Tree) tells of a poor, young farmer who fell in love with his landlord's beautiful daughter. The farmer asked the landlord for his daughter's hand in marriage, but the proud landlord would not allow her to be bound in marriage to a poor farmer. The landlord decided to foil the marriage with an impossible deal; the farmer must bring him a "bamboo tree of 100 nodes". But Gautama Buddha (Bụt) appeared to the farmer and told him that such a tree could be made from 100 nodes from several different trees. Bụt gave to him four magic words to attach the many nodes of bamboo: Khắc nhập, khắc xuất, which means "joined together immediately, fell apart immediately". The triumphant farmer returned to the landlord and demanded his daughter. Curious to see such a long bamboo, the landlord was magically joined to the bamboo when he touched it, as the young farmer said the first two magic words. The story ends with the happy marriage of the farmer and the landlord's daughter after the landlord agreed to the marriage and asked to be separated from the bamboo.

 

In a Chinese legend, the Emperor Yao gave two of his daughters to the future Emperor Shun as a test for his potential to rule. Shun passed the test of being able to run his household with the two emperor's daughters as wives, and thus Yao made Shun his successor, bypassing his unworthy son. Later, Shun drowned in the Xiang River. The tears his two bereaved wives let fall upon the bamboos growing there explains the origin of spotted bamboo. The two women later became goddesses.

Construction

 

General W. F. Hase was launched under a Maritime Commission (MARCOM) contract, MC hull No. 662, 15 December 1943 by Permanente Metals Corporation, Yard No. 3, Richmond, California; sponsored by Mrs. John E. Wood, Jr.; acquired by the Navy and simultaneously placed in a ferry commission 22 April 1944, during transfer for conversion to a transport by Kaiser Co., Inc., Vancouver, Washington; and placed in full commission at Portland, Oregon, 6 June 1944, Commander W. W. Keller in command.[3]

Service history

 

After shakedown out of San Pedro, General W. F. Hase departed San Francisco 15 July 1944, with 3,000 troops and $29 million in military currency. After touching at Pearl Harbor, she debarked the fighting men at Eniwetok, returning to San Francisco 26 August, with 2,100 soldiers. Between 20 September and 1 November, the transport steamed out of Seattle, carrying more than 2,000 troops to Pearl Harbor and 2,800 thence to Manus, Admiralty Islands, before returning to San Francisco with 2,500 veterans of the New Guinea campaign on board. Continuing to support the westward drive of naval forces in the Western Pacific, between 23 November and 20 April 1945, she made two round trips out of San Francisco, shuttling troops to New Guinea and the Philippines and bringing home veterans from New Caledonia and Manus.[3]

 

During the next 12 months General W. F. Hase made six round-trip voyages, including two circumnavigations of the earth, while deploying troops to and from the United States. Departing San Pedro 9 May, she carried 2,600 troops to Melbourne, Australia, where she arrived 27 May. After steaming to Fremantle, Australia, she reached Calcutta, India, 14 June, and embarked 2,500 homebound soldiers. She then sailed for the United States via Ceylon and the Suez Canal and arrived Norfolk 20 July. She departed Norfolk 5 August for the Mediterranean; and as part of the "Magic Carpet" fleet, she embarked more than 3,000 troops at Marseilles, France, before returning to New York 27 August. Operating out of New York between 1 September and 27 December, she sailed twice to Calcutta and back with more than 6,000 troops. On 11 January 1946, she again departed New York for Calcutta; and, after embarking 2,900 troops 8 February, she steamed via Manila to the West Coast, arriving San Francisco 8 March. Between 1 and 15 April, she carried 1,000 occupation troops to Yokohama, Japan; and on her final "Magic Carpet" voyage she returned 2,800 veterans to Seattle 28 April.[3]

Decommissioning - transfer to US Army

 

General W. F. Hase steamed to San Francisco 3 to 4 May, decommissioned there 6 June, and, simultaneously, was returned to War Shipping Administration (WSA) for use as a transport by the Army Transportation Service (ATS).[3]

Transfer to Military Sea Transportation Service

 

She was reacquired by the Navy 1 March 1950, and assigned to duty with Military Sea Transportation Service (MSTS)). Manned by a civilian crew, she operated out of San Francisco, carrying more than 75,000 troops and their combat cargo to the Far East in support of the Korean War. Between 1950 and 1953 she made 19 round-trip voyages to Japan and Korea, and she returned to San Francisco from her final Far East deployment 29 August 1953. Towed to San Diego in June 1954, she was placed out of service in reserve in July, and remained inactive until returned to the Maritime Administration (MARAD) 8 January 1960, when she was berthed in the National Defense Reserve Fleet at Suisun Bay, California.[3]

Merchant service

 

Title was transferred to Hudson Waterways Corporation, 16 July 1968, under the MARAD Exchange program for SS Zephyrhills ex-Seven Pines,[4] and she was delivered to Hudson Waterways Corp. on 30 July 1968. The ship was converted to a container ship by the Maryland Shipbuilding and Drydock Company in 1969 and renamed SS Transidaho, USCG ON 515622, IMO 6904856, in November. Upon completion she began hauling containerized cargo for Seatrain Lines. On 14 October 1974 the ship was sold to the Puerto Rico Maritime Shipping Authority and she was renamed SS Carolina on 1 March 1975. She was resold to the Point Vigilance Corp. on 10 July 1981 and renamed SS Point Manatee. She was sold for scrapping on 15 October 1984 to Goldwiles Texas Inc. and was broken up in Taiwan in 1985.[5]

Awards

 

General W. F. Hase received eight battle stars for Korean war service.[3]

Container ships (sometimes spelled containerships) are cargo ships that carry all of their load in truck-size intermodal containers, in a technique called containerization. They are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo.

 

Container ship capacity is measured in twenty-foot equivalent units (TEU). Typical loads are a mix of 20-foot and 40-foot (2-TEU) ISO-standard containers, with the latter predominant.

 

Today, about 90% of non-bulk cargo worldwide is transported by container, and modern container ships can carry over 19,000 TEU (e.g., MSC Zoe). Container ships now rival crude oil tankers and bulk carriers as the largest commercial vessels on the ocean.

 

HISTORY

There are two main types of dry cargo: bulk cargo and break bulk cargo. Bulk cargoes, like grain or coal, are transported unpackaged in the hull of the ship, generally in large volume. Break-bulk cargoes, on the other hand, are transported in packages, and are generally manufactured goods. Before the advent of containerization in the 1950s, break-bulk items were loaded, lashed, unlashed and unloaded from the ship one piece at a time. However, by grouping cargo into containers, 28 to 85 m3 of cargo, or up to about 29,000 kg, is moved at once and each container is secured to the ship once in a standardized way. Containerization has increased the efficiency of moving traditional break-bulk cargoes significantly, reducing shipping time by 84% and costs by 35%. In 2001, more than 90% of world trade in non-bulk goods was transported in ISO containers. In 2009, almost one quarter of the world's dry cargo was shipped by container, an estimated 125 million TEU or 1.19 billion metric tons worth of cargo.

 

The first ships designed to carrying standardized load units were use in the late 18th century in England . In 1766 James Brindley designed the box boat “Starvationer” with 10 wooden containers, to transport coal from Worsley Delph to Manchester by Bridgewater Canal. Before the Second World War first container ships were used to carrying baggages of the luxury passenger train from London to Paris, Golden Arrow/Fleche d'Or, in 1926 by Southern Railway. These containers were loaded in London or Paris and carried to ports, Dover or Calais, on flat cars in the UK and “CIWL Pullman Golden Arrow Fourgon of CIWL” in France.

 

The earliest container ships after Second Word War were converted tankers, built up from surplus T2 tankers after World War II. In 1951, the first purpose-built container vessels began operating in Denmark, and between Seattle and Alaska. The first commercially successful container ship was the Ideal X, a T2 tanker, owned by Malcom McLean, which carried 58 metal containers between Newark, New Jersey and Houston, Texas on its first voyage. In 1955, McLean built his company, McLean Trucking into one of United States' biggest freighter fleets. In 1955, he purchased the small Pan Atlantic Steamship Company from Waterman Steamship and adapted its ships to carry cargo in large uniform metal containers. On April 26, 1956, the first of these rebuilt container vessels, the Ideal X, left the Port Newark in New Jersey and a new revolution in modern shipping resulted.

 

Container vessels eliminate the individual hatches, holds and dividers of the traditional general cargo vessels. The hull of a typical container ship is a huge warehouse divided into cells by vertical guide rails. These cells are designed to hold cargo in pre-packed units – containers. Shipping containers are usually made of steel, but other materials like aluminum, fiberglass or plywood are also used. They are designed to be entirely transferred to and from smaller coastal carriers, trains, trucks and/or semi-trailers (and so are carried by different modes of transport during one voyage, thus giving the name intermodal transport) There are several types of containers and they are categorized according to their size and functions.

 

Today, about 90% of non-bulk cargo worldwide is transported by container, and modern container ships can carry up to 16,020 twenty-foot equivalent units (TEU) (CMA CGM Marco Polo). As a class, container ships now rival crude oil tankers and bulk carriers as the largest commercial vessels on the ocean.

 

Although containerization caused a revolution in the world of shipping, its introduction did not have an easy passage. Ports, railway (railroad in the US) companies, and shippers were concerned about the huge costs of developing the ports and railway infrastructure needed to handle container ships, and for the movement of containers on land by rail and road. Trade unions were concerned about massive job loss among port and dock workers at ports, as containers were sure to eliminate several manual jobs of cargo handling at ports. It took ten years of legal battles before container ships would be pressed into international service. In 1966, a container liner service from the USA to the Dutch city of Rotterdam commenced. Containerization changed not only the face of shipping, but it also revolutionized world trade as well. A container ship can be loaded and unloaded in a few hours compared to days in a traditional cargo vessel. This, besides cutting labor costs, has reduced shipping times between ports to a great extent; for example, it takes a few weeks instead of months for a consignment to be delivered from India to Europe and vice versa. It has also resulted in less breakage due to less handling; also, there is less danger of cargo shifting during a voyage. As containers are sealed and only opened at the destination, pilferage and theft levels have been greatly reduced.

 

Containerization has lowered shipping expense and decreased shipping time, and this has in turn helped the growth of international trade. Cargo that once arrived in cartons, crates, bales, barrels or bags now comes in factory sealed containers, with no indication to the human eye of their contents, except for a product code that machines can scan and computers trace. This system of tracking has been so exact that a two-week voyage can be timed for arrival with an accuracy of under fifteen minutes. It has resulted in such revolutions as on time guaranteed delivery and just in time manufacturing. Raw materials arrive from factories in sealed containers less than an hour before they are required in manufacture, resulting in reduced inventory expense.

 

The aforementioned reduction in ship operating costs accrue to companies owning or operating container ships. But for others connected with trade, such as ports, railways, road transporters and trade (exporters and importers), the operating costs have risen exponentially. Several elements of costs that were borne in the past by ship operators are now borne by trade, as standard terms of carriage of goods by sea have now been drastically revised by container-shipping lines. Despite saving in operating costs, shipping freight have not fallen significantly because freight is globally fixed sector-wise by shipping cartels.

 

In short, containers have helped to optimize the operation of ships, while the additional burden of ancillary costs that has been transferred from ships onto other (i.e. onshore) entities is normally ignored in public perception.

 

Exporters load merchandise in boxes that are provided by the shipping companies. They are then delivered to the docks by road, rail or a combination of both for loading on to container ships. Prior to containerization, huge gangs of men would spend hours fitting various items of cargo into different holds. Today, cranes, installed either on the pier or on the ship, are used to place containers on board the ship. When the hull has been fully loaded, additional containers are stacked on the deck.

 

Today's largest container ships measure almost 400 metres in length. They carry loads equal to the cargo-carrying capacity of sixteen to seventeen pre-WWII freighter ships.

 

ARCHITECTURE

There are several key points in the design of modern container ships. The hull, similar to bulk carriers and general cargo ships, is built around a strong keel. Into this frame is set one or more below-deck cargo holds, numerous tanks, and the engine room. The holds are topped by hatch covers, onto which more containers can be stacked. Many container ships have cargo cranes installed on them, and some have specialized systems for securing containers on board.

 

The hull of a modern cargo ship is a complex arrangement of steel plates and strengthening beams. The hull is built around the keel. Resembling ribs, and fastened at right-angles to the keel are the ship's frames. The ship's main deck, the metal platework that covers the top of the hull framework, is supported by beams that are attached to the tops of the frames and run the full breadth of the ship. The beams not only support the deck, but along with the deck, frames, and transverse bulkheads, strengthen and reinforce the shell. Another feature of recent hulls is a set of double-bottom tanks, which provide a second watertight shell that runs most of the length of a ship. The double-bottoms generally hold liquids such as fuel oil, ballast water or fresh water.

 

A ship's engine room houses its main engines and auxiliary machinery such as the fresh water and sewage systems, electrical generators, fire pumps, and air conditioners. In most new ships, the engine room is located in the aft portion of the ship.

 

SIZE CATEGORIES

Container ships are distinguished into 7 major size categories: small feeder, feeder, feedermax, panamax, post-panamax, new panamax and ultra-large. As of December 2012, there are 161 container ships in the VLCS class (Very Large Container Ships, more than 10,000 TEU), and 51 ports in the world can accommodate them.

 

The size of a panamax vessel is limited by the Panama canal's lock chambers, which can accommodate ships with a beam of up to 32.31 m, a length overall of up to 294.13 m, and a draft of up to 12.04 m. The "post panamax" category has historically been used to describe ships with a moulded breadth over 32.31 m, however the Panama Canal expansion project is causing some changes in terminology. The "new panamax" category is based on the maximum vessel-size that will be able to transit a new third set of locks. The new locks are being built to accommodate a container ship with a length overall of 366 metres, a maximum width of 49 metres, and tropical fresh-water draft of 15.2 metres. Such a vessel would be wide enough to carry 19 rows of containers, have a total capacity of approximately 12,000 TEU and be comparable in size to a capesize bulk carrier or a suezmax tanker.

 

Container ships under 3,000 TEU are generally called feeders. Feeders are small ships that typically operate between smaller container ports. Some feeders collect their cargo from small ports, drop it off at large ports for transshipment on larger ships, and distribute containers from the large port to smaller regional ports. This size of vessel is the most likely to carry cargo cranes on board.

 

CARGO CRANES

A major characteristic of a container ship is whether it has cranes installed for handling its cargo. Those that have cargo cranes are called geared and those that don't are called ungeared or gearless. The earliest purpose-built container ships in the 1970s were all gearless. Since then, the percentage of geared newbuilds has fluctuated widely, but has been decreasing overall, with only 7.5% of the container ship capacity in 2009 being equipped with cranes.

 

While geared container ships are more flexible in that they can visit ports that are not equipped with pierside container cranes, they suffer from several drawbacks. To begin with, geared ships will cost more to purchase than a gearless ship. Geared ships also incur greater recurring expenses, such as maintenance and fuel costs. The United Nations Council on Trade and Development characterizes geared ships as a "niche market only appropriate for those ports where low cargo volumes do not justify investment in port cranes or where the public sector does not have the financial resources for such investment."

 

Instead of the rotary cranes, some geared ships have gantry cranes installed. These cranes, specialized for container work, are able to roll forward and aft on rails. In addition to the additional capital expense and maintenance costs, these cranes generally load and discharge containers much more slowly than their shoreside counterparts.

 

The introduction and improvement of shoreside cranes have been a key to the success of the container ship. The first crane that was specifically designed for container work was built in California's Port of Alameda in 1959. By the 1980s, shoreside gantry cranes were capable of moving containers on a 3-minute-cycle, or up to 400 tons per hour. In March 2010, at Port Klang in Malaysia, a new world record was set when 734 container moves were made in a single hour. The record was achieved using 9 cranes to simultaneously load and unload the MV CSCL Pusan, a ship with a capacity of 9,600 TEU.

 

Vessels in the 1,500–2,499 TEU range are the most likely size class to have cranes, with more than 60% of this category being geared ships. Slightly less than a third of the very smallest ships (from 100–499 TEU) are geared, and almost no ships with a capacity of over 4,000 TEU are geared.

Cargo holds

 

Efficiency has always been key in the design of container ships. While containers may be carried on conventional break-bulk ships, cargo holds for dedicated container ships are specially constructed to speed loading and unloading, and to efficiently keep containers secure while at sea. A key aspect of container ship specialization is the design of the hatches, the openings from the main deck to the cargo holds. The hatch openings stretch the entire breadth of the cargo holds, and are surrounded by a raised steel structure known as the hatch coaming. On top of the hatch coamings are the hatch covers. Until the 1950s, hatches were typically secured with wooden boards and tarpaulins held down with battens. Today, some hatch covers can be solid metal plates that are lifted on and off the ship by cranes, while others are articulated mechanisms that are opened and closed using powerful hydraulic rams.

 

Another key component of dedicated container-ship design is the use of cell guides. Cell guides are strong vertical structures constructed of metal installed into a ship's cargo holds. These structures guide containers into well-defined rows during the loading process and provide some support for containers against the ship's rolling at sea. So fundamental to container ship design are cell guides that organizations such as the United Nations Conference on Trade and Development use their presence to distinguish dedicated container ships from general break-bulk cargo ships.

 

A system of three dimensions is used in cargo plans to describe the position of a container aboard the ship. The first coordinate is the row, which starts at the front of the ship and increases aft. The second coordinate is tier, with the first tier at the bottom of the cargo holds, the second tier on top of that, and so forth. The third coordinate is the slot. Slots on the starboard side are given odd numbers and those on the port side are given even numbers. The slots nearest the centerline are given low numbers, and the numbers increase for slots further from the centerline.

 

Container ships only take 20 foot, 40 foot, and 45 foot containers. 45 footers only fit above deck. 40 foot containers are the primary container size, making up about 90% of all container shipping and since container shipping moves 90% of the world's freight, over 80% of the world's freight moves via 40 foot containers.

 

LASHING SYSTEMS

Numerous systems are used to secure containers aboard ships, depending on factors such as the type of ship, the type of container, and the location of the container. Stowage inside the holds of fully cellular (FC) ships is simplest, typically using simple metal forms called container guides, locating cones, and anti-rack spacers to lock the containers together. Above-decks, without the extra support of the cell guides, more complicated equipment is used. Three types of systems are currently in wide use: lashing systems, locking systems, and buttress systems. Lashing systems secure containers to the ship using devices made from wire rope, rigid rods, or chains and devices to tension the lashings, such as turnbuckles. The effectiveness of lashings is increased by securing containers to each other, either by simple metal forms (such as stacking cones) or more complicated devices such as twist-lock stackers. A typical twist-lock is inserted into the casting hole of one container and rotated to hold it in place, then another container is lowered on top of it. The two containers are locked together by twisting the device's handle. A typical twist-lock is constructed of forged steel and ductile iron and has a shear strength of 48 metric tons.

 

The buttress system, used on some large container ships, uses a system of large towers attached to the ship at both ends of each cargo hold. As the ship is loaded, a rigid, removable stacking frame is added, structurally securing each tier of containers together.

 

BRIDGE

Containerships have typically had a single bridge and accommodation unit towards the rear, but to reconcile demand for larger container capacity with SOLAS visibility requirements, several new designs have been developed. As of 2015, some large containerships are being developed with the bridge further forward, separate from the exhaust stack. Some smaller containerships working in European ports and rivers have liftable wheelhouses, which can be lowered to pass under low bridges. HHI has developed the Skybench movable bridge to allow more capacity on large containerships.

 

FLEET CHARACTERISTICS

As of 2010, container ships made up 13.3% of the world's fleet in terms of deadweight tonnage. The world's total of container ship deadweight tonnage has increased from 11 million DWT in 1980 to 169.0 million DWT in 2010. The combined deadweight tonnage of container ships and general cargo ships, which also often carry containers, represents 21.8% of the world's fleet.

 

As of 2009, the average age of container ships worldwide was 10.6 years, making them the youngest general vessel type, followed by bulk carriers at 16.6 years, oil tankers at 17 years, general cargo ships at 24.6 years, and others at 25.3 years.

 

Most of the world's carrying capacity in fully cellular container ships is in the liner service, where ships trade on scheduled routes. As of January 2010, the top 20 liner companies controlled 67.5% of the world's fully cellular container capacity, with 2,673 vessels of an average capacity of 3,774 TEU. The remaining fully 6,862 fully cellular ships have an average capacity of 709 TEU each.

 

The vast majority of the capacity of fully cellular container ships used in the liner trade is owned by German shipowners, with approximately 75% owned by Hamburg brokers. It is a common practice for the large container lines to supplement their own ships with chartered-in ships, for example in 2009, 48.9% of the tonnage of the top 20 liner companies was chartered-in in this manner.

 

FLAG STATES

International law requires that every merchant ship be registered in a country, called its flag state. A ship's flag state exercises regulatory control over the vessel and is required to inspect it regularly, certify the ship's equipment and crew, and issue safety and pollution prevention documents. As of 2006, the United States Bureau of Transportation Statistics count 2,837 container ships of 10,000 long tons deadweight (DWT) or greater worldwide. Panama was the world's largest flag state for container ships, with 541 of the vessels in its registry. Seven other flag states had more than 100 registered container ships: Liberia (415), Germany (248), Singapore (177), Cyprus (139), the Marshall Islands (118) and the United Kingdom (104). The Panamanian, Liberian, and Marshallese flags are open registries and considered by the International Transport Workers' Federation to be flags of convenience. By way of comparison, traditional maritime nations such as the United States and Japan only had 75 and 11 registered container ships, respectively.

 

VESSEL PURCHASES

In recent years, oversupply of container ship capacity has caused prices for new and used ships to fall. From 2008 to 2009, new container ship prices dropped by 19–33%, while prices for 10-year-old container ships dropped by 47–69%. In March 2010, the average price for a geared 500-ton container ship was $10 million, while gearless ships of 6,500 and 12,000 TEU averaged prices of $74 million and $105 million respectively. At the same time, secondhand prices for 10-year-old geared container ships of 500-, 2,500-, and 3,500-TEU capacity averaged prices of $4 million, $15 million, and $18 million respectively.

 

In 2009, 11,669,000 gross tons of newly built container ships were delivered. Over 85% of this new capacity was built in the Republic of Korea, China, and Japan, with Korea accounting for over 57% of the world's total alone. New container ships accounted for 15% of the total new tonnage that year, behind bulk carriers at 28.9% and oil tankers at 22.6%.

 

SCRAPPING

Most ships are removed from the fleet through a process known as scrapping. Scrapping is rare for ships under 18 years old and common for those over 40 years in age. Ship-owners and buyers negotiate scrap prices based on factors such as the ship's empty weight (called light ton displacement or LTD) and prices in the scrap metal market. Scrapping rates are volatile, the price per light ton displacement has swung from a high of $650 per LTD in mid-2008 to $200 per LTD in early 2009, before building to $400 per LTD in March 2010. As of 2009, over 96% of the world's scrapping activity takes place in China, India, Bangladesh, and Pakistan.

 

The global economic downturn of 2008–2009 resulted in more ships than usual being sold for scrap. In 2009, 364,300 TEU worth of container ship capacity was scrapped, up from 99,900 TEU in 2008. Container ships accounted for 22.6% of the total gross tonnage of ships scrapped that year. Despite the surge, the capacity removed from the fleet only accounted for 3% of the world's containership capacity. The average age of container ships scrapped in 2009 was 27.0 years.

 

LARGEST SHIPS

Economies of scale have dictated an upward trend in sizes of container ships in order to reduce expense. However, there are certain limitations to the size of container ships. Primarily, these are the availability of sufficiently large main engines and the availability of a sufficient number of ports and terminals prepared and equipped to handle ultra-large container ships. Furthermore, the permissible maximum ship dimensions in some of the world's main waterways could present an upper limit in terms of vessel growth. This primarily concerns the Suez Canal and the Singapore Strait.

 

In 2008 the South Korean shipbuilder STX announced plans to construct a container ship capable of carrying 22,000 TEU, and with a proposed length of 450 metres and a beam of 60 metres. If constructed, the container ship would become the largest seagoing vessel in the world.

 

Since even very large container ships are vessels with relatively low draft compared to large tankers and bulk carriers, there is still considerable room for vessel growth. Compared to today's largest container ships, Maersk Line's 15,200 TEU Emma Mærsk-type series, a 20,000 TEU container ship would only be moderately larger in terms of exterior dimensions. According to a 2011 estimate, an ultra-large container ship of 20,250 TEU would measure 440m x 59m, compared to 397.71 × 56.40m for the Emma Mærsk class. It would have an estimated deadweight of circa 220,000 tons. While such a vessel might be near the upper limit for a Suez Canal passage, the so-called Malaccamax concept (for Straits of Malacca) does not apply for container ships, since the Malacca and Singapore Straits' draft limit of about 21 metres is still above that of any conceivable container ship design. In 2011, Maersk announced plans to build a new "Triple E" family of containerships with a capacity of 18,000TEU, with an emphasis on lower fuel consumption.In the present market situation, main engines will not be as much of a limiting factor for vessel growth either. The steadily rising expense of fuel oil has prompted most container lines to adapt a slower, more economical voyage speed of about 21 knots, compared to earlier top speeds of 25 or more knots. Subsequently, new-built container ships can be fitted with a smaller main engine. Engine types fitted to today's ships of 14,000 TEU are thus sufficiently large to propel future vessels of 20,000 TEU or more. Maersk Line, the world's largest container shipping line, nevertheless opted for twin engines (two smaller engines working two separate propellers), when ordering a series of ten 18,000 TEU vessels from Daewoo Shipbuilding in February 2011. The ships will be delivered between 2013 and 2014.

 

FREIGHT MARKET

The act of hiring a ship to carry cargo is called chartering. Outside special bulk cargo markets, ships are hired by three types of charter agreements: the voyage charter, the time charter, and the bareboat charter. In a voyage charter, the charterer rents the vessel from the loading port to the discharge port. In a time charter, the vessel is hired for a set period of time, to perform voyages as the charterer directs. In a bareboat charter, the charterer acts as the ship's operator and manager, taking on responsibilities such as providing the crew and maintaining the vessel. The completed chartering contract is known as a charter party.

 

The United Nations Conference on Trade and Development, or UNCTAD, in its 2010 Review of Maritime Trade tracks two aspects of container shipping prices. The first is a chartering price, specifically the price to time-charter a 1 TEU slot for a 14 metric ton cargo on a container ship. The other is the freight rate, or comprehensive daily cost to deliver one-TEU worth of cargo on a given route. As a result of the late-2000s recession, both indicators showed sharp drops during 2008–2009, and have shown signs of stabilization since 2010.

 

UNCTAD uses the Hamburg Shipbrokers’ Association (formally the Vereinigung Hamburger Schiffsmakler und Schiffsagenten e. V. or VHSS for short) as its main industry source for container ship freight prices. The VHSS maintains a few indices of container ship charter prices. The oldest, which dates back to 1998, is called the Hamburg Index. This index considers time-charters on fully cellular containerships controlled by Hamburg brokers. It is limited to charters of 3 months or more, and presented as the average daily cost in U.S. dollars for a one-TEU slot with a weight of 14 metric tons. The Hamburg Index data is divided into ten categories based primarily on vessel carrying capacity. Two additional categories exist for small vessels of under 500 TEU that carry their own cargo cranes. In 2007, VHSS started another index, the New ConTex which tracks similar data obtained from an international group of shipbrokers.

 

The Hamburg Index shows some clear trends in recent chartering markets. First, rates were generally increasing from 2000 to 2005. From 2005 to 2008, rates slowly decreased, and in mid-2008 began a "dramatic decline" of approximately 75%, which lasted until rates stabilized in April 2009. Rates have ranged from $2.70 to $35.40 in this period, with prices generally lower on larger ships. The most resilient sized vessel in this time period were those from 200–300 TEU, a fact that the United Nations Council on Trade and Development attributes to lack of competition in this sector. Overall, in 2010, these rates rebounded somewhat, but remained at approximately half of their 2008 values. As of 2011, the index shows signs of recovery for container shipping, and combined with increases in global capacity, indicates a positive outlook for the sector in the near future.

 

UNCTAD also tracks container freight rates. Freight rates are expressed as the total price in U.S. dollars for a shipper to transport one TEU worth of cargo along a given route. Data is given for the three main container liner routes: U.S.-Asia, U.S.-Europe, and Europe-Asia. Prices are typically different between the two legs of a voyage, for example the Asia-U.S. rates have been significantly higher than the return U.S.-Asia rates in recent years. Generally, from the fourth quarter of 2008 through the third quarter of 2009, both the volume of container cargo and freight rates have dropped sharply. In 2009, the freight rates on the U.S.–Europe route were sturdiest, while the Asia-U.S. route fell the most.

 

Liner companies responded to their overcapacity in several ways. For example, in early 2009, some container lines dropped their freight rates to zero on the Asia-Europe route, charging shippers only a surcharge to cover operating costs. They decreased their overcapacity by lowering the ships' speed (a strategy called "slow steaming") and by laying up ships. Slow steaming increased the length of the Europe-Asia routes to a record high of over 40 days. Another strategy used by some companies was to manipulate the market by publishing notices of rate increases in the press, and when "a notice had been issued by one carrier, other carriers followed suit."

 

The Trans-Siberian Railroad (TSR) has recently become a more viable alternative to container ships on the Asia-Europe route. This railroad can typically deliver containers in 1/3 to 1/2 of the time of a sea voyage, and in late 2009 announced a 20% reduction in its container shipping rates.[91] With its 2009 rate schedule, the TSR will transport a forty-foot container to Poland from Yokohama for $2,820, or from Pusan for $2,154.

 

SHIPPING INDUSTRY ALLIANCES

In an effort to control costs and maximize capacity utilization on ever larger ships, vessel sharing agreements, co-operative agreements and slot-exchanges and have become a growing feature of the maritime container shipping industry. As of March 2015, 16 of the world’s largest container shipping lines had consolidated their routes and services accounting for 95 percent of container cargo volumes moving in the dominant east-west trade routes.

 

Carriers remain operationally independent, forbidden by antitrust regulators in multiple jurisdictions from colluding on freight rates or capacity.

 

CONTAINER PORTS

Container traffic through a port is often tracked in terms of twenty foot equivalent units or TEU of throughput. As of 2009, the Port of Singapore was the world's busiest container port, with 25,866,000 TEU handled.[93] That year, six of the busiest ten container ports were in the People's Republic of China, with Shanghai in 2nd place, Port of Hong Kong in 3rd, Shenzhen 4th, Guangzhou 6th, Ningbo 8th, and Qingdao 9th. Rounding out the top ten ports were Busan in South Korea at number 5, Dubai in the United Arab Emirates at number 7, and Rotterdam in the Netherlands in the 10th position with 9,743,290 TEU served. In total, the busiest twenty container ports handled 220,905,805 TEU in 2009, almost half of the world's total estimated container traffic that year of 465,597,537 TEU.

 

SAFETY ISSUES

In March 2007, a London-based container ship capsized in Antwerp, Belgium while loading.

 

Maneuvers in coastal waters and ports managed in the wheel house may be dangerous, as evidenced by a container ship hitting the San Francisco – Oakland Bay Bridge on November 7, 2007.

 

It has been estimated that container ships lose between 2,000 and 10,000 containers at sea each year, costing $370 million per year. Most go overboard on the open sea during storms but there are some examples of whole ships being lost with their cargo. When containers are dropped, they immediately become an environmental threat – termed "marine debris". Once in the ocean, they fill with water and sink if the contents cannot hold air. Rough waters smash the container, sinking it quickly.

 

The threat of piracy can cost a container shipping company as much as $100 million per year due to longer routes and higher speed, particularly near East Africa.

 

WIKIPEDIA

Introduced and expanded through the 1920s and 1930s, the forklift truck revolutionised freight handling. Development of hydraulic and electric power, along with use of standard sized pallets in the late 1930s, increased efficiency and reduced manpower in the warehouse. Containerization, as we know it today, was not well developed or widely applied until after World War II, when it dramatically reduced cost of transport,

Image from a vintage asbestos abatement industry publication showing workers posing inside an apparent asbestos abatement work area while demonstrating cleaning activities. Abatement workers are depicted with disposable coveralls, supplied-air full-face respirators, and a portable air monitoring device (worker in background).

 

This advertising photo attempts to portray some basic aspects of asbestos abatement, but might have missed a few details for realism in this obvious staged set-up, such as the apparent absence of negative air pressurization acting on the polyethylene-sheet wall and floor barriers. Along this line, the placement of the negative air machine (NAM) itself appears to show its intake opening directly against the enclosure wall, hindering its ability to draw airflow (doubtful if it was actually activated); NAM intake should be directed toward the main portion of the work area. Additionally, there doesn't even seem to be an electrical cord leading to the NAM.

 

Further, there seems to be a distinct absence of a wetting-agent and associated applicator (no water, hose, or reservoir container); everything appears to be "dry". One of the main factors in proper asbestos abatement dust control technique is assuring materials are "adequately wet", which can greatly reduce the potential for dust particles to become airborne, typically achieved by wetting materials and work area surfaces before, during and after ACM removal. Even the worker wiping the enclosure wall should be using a wet towel or damp rag, but where is the bucket of cleaning solution? Plus, such wiping activity is usually reserved for the "final cleaning" stage, well after bulk ACM debris has been removed and containerized.

 

In addition to this, the assumed "asbestos" debris on the floor should've been "promptly" containerized as it was removed, not allowed to accumulate where it could be further disturbed by trampling it, haphazardly dragging hoses and equipment over it, etc., likely causing asbestos fibers to become airborne and further contaminate surfaces. Loose bulk debris also compounds cleaning efforts by unnecessarily spending more time and resources to decontaminate exposed equipment and supplies from excessive debris build-up. Further, the workers themselves in this image appear to have managed keeping their coveralls and gloves perfectly spotless, an amazing feat inside an "active" asbestos abatement work area during bulk removal.

 

Not to mention, the fact that the personal air monitoring device is attached to the worker performing the least riskiest job function -in this example - relative to airborne asbestos fiber exposure - wiping walls; whereas the other workers are pictured vacuuming and shoveling apparent bulk friable insulation material. Air monitoring results would probably not be fully representative of job tasks with the potential highest exposure risk.

 

A couple of other points: larger areas of accumulated bulk debris such as this are often cleaned using shovels and not necessarily utilizing vacuums, since the excessive bulk material reduces the service-life of the vucuum's costly HEPA-filter much quicker, tends to clog more frequently, and would also fill the vacuum canister or bag quite often, requiring frequent emptying or bag replacement. HEPA-vacuuming is typically employed for residual materials on surfaces, following substantial removal and cleanup of bulk debris.

 

Although perhaps a smidgeon of credit is due, since there doesn't appear to be evidence of a broom or brush inside the work area (at least not on camera). Dry-sweeping asbestos material is strictly prohibited. But, some asbestos abatement workers might have another opinion about that.

 

Also, the kneeling worker holding open the black waste bag does not appear to have an adequate fit "inside" his full-face respirator. The internal seal around his nose and mouth looks breached, consequently not providing the full level of protection these types of respirators are designed for.

 

Ah, but who's looking anyway?

The pictures were about the misbehavior of the people in this birth and consequences of the deeds when they enter the next birth.It was put in to pictures in a way kind of calling to one to refrain from bad deeds.Students were awarded of the Eight fold path way revealed by Loard Bhudhdha and the statues of the temple was very helpful to depict.After taking the lunch of the day one @ the same temple we left for Dambulla Rock temple.

 

Dambulla Rock temple is more impotent to Art Students coz of its wall paintings.Dambulla temple is one of the masters peace of Buddhist Rock cravings and the watershed technologies used by the ancient people.All the students climbed up to the caves and worshiped there.there after We left for Anuradhapura where our day one accommodations were readied.The Night meal was cooked by the accompanied parents with the help of teachers and Senior Girls.Senior Boys were divided in to groups and assigned duties Accordingly.The parents woke up early morning with teachers and again prepared breakfast and lunch all together.We server break fast and containerized the Lunch.We left the technical College of Anuradhapura At about 7.30am And reached to the Isurumuniya Raja Maha Viharaya by 10 minutes traveling.

 

Isurumuniya is another impotent place for Sinhala Buddhist.there is a 6th Century Gupta style carving. The woman, seated on the man's lap, lifts a warning finger, probably as a manifestation of her coyness; but the man carries on regardless."

The figures may represent The Great King Dutugemunu's son Saliya and the law caste (Sadol Kula) maiden Asokamala whom he loved. It's known that he gave up the throne for her.

 

After the Isurumuniya we left for 'mirisaweliya' next to it.Mirisawetiya was built by the great King Dutugamunu who reigned during the time (161-137 BC) and united Sri Lanka under a single flag.

 

It is believed that King Dutugamunu had a sceptre that contained a scared relic of the Buddha. While going to the tank “Tissawewa”, for a water festival, the King has planted the scepter in a certain place. When he came back, it is said that his men could not remove the scepter from the place.

 

Witnessing the miracle, the King decided to build a dagaba enclosing the scepter. Thus was the creation of Mirisawetiya.

 

The significance of the scepter is the fact that this was the king's "victory scepter" for his battles with Elara, and by building the Dagaba around it shows the tremendous dedication that the King had for Buddhism and his spirituality.Mirisawetiya was the first dagaba built by the great king Dutugamunu.

 

After that we left for Ruwanweli Saya.The Ruwanwelisaya is a stupa in Sri Lanka, considered a marvel for its architectural qualities and sacred to many Buddhists all over the world. It was built by King Dutugemunu, who became lord of all Sri Lanka after a war in which the Chola King Elara, were defeated. It is also known as Mahathupa, Swarnamali Chaitya and Rathnamali Dagaba.

 

The stupa is also one of the Solosmasthana (the 16 places of veneration) and the Atamasthana (the 8 places of veneration in the ancient sacred city of Anuradhapura). The stupa is one of the world's tallest monuments, standing at 300 ft (92 m) and with a circumference of 950 ft (292 m).

 

Then we left for Jaya Shi Maha Bodhiya.The 'Bo' ( 'Bodhi') tree or Pipal (ficus religiosa) was planted as a cutting brought from India by by emperor Ashoka's daughter, the Princess Sangamitta, at some point after 236 BC. Guardians have kept uninterrupted watch over the tree ever since. There are other Bo trees around the Sir Maha Bodhi which stands on the highest terrace. In April a large number of pilgrims arrive to make offering during the Snana Pooja, and to bathe the tree with milk. Every 12th year the ceremony is particularly auspicious.

After the Sri Maha Bhodiya we vent to worship Thuparamaya.Thera Mahinda him self had introduce Theravada Buddhism and also chetiya worship to Sri Lanka. At his request King Devanampiyatissa built Thuparamaya in which was enshrined the collarbone of the Buddha and is considered as the first dagaba built in Sri Lanka, after the introduction of Buddhism. This is considered the earliest monument of chronicled Sri Lanka. The name Thuparamaya comes from "stupa" and "aramaya" which is a residential complex for monks.

 

This chetiya was built in the shape of a heap of paddy. This dagaba was destroyed from time to time. During the reign of King Agbo II it was completely destroyed and the King restored it. What we have today is the construction of the dagaba, done in 1862 AD. As it is today, after several renovations, in the course of the centuries, the monument has a diameter of 59 ft (18 m), at the base. The dome is 11 feet 4 inches (3.45 m) in height from the ground, 164½ ft (50.1 m) in diameter. The compound is paved with granite and there are 2 rows of stone pillars round the dagaba. During the early period vatadage was built round the dagaba.

 

After that we went to see Sandakadapahana.The Best of the Moon Stones we have in Sri Lanka is the one which is at the entrance to the palace of King Mahasen. According to Dr. Senarath Paranawithana, there is a deep philosophy underlying these carvings found in this Moon Stone.

 

We can clearly see the Hindu influence on the Moon Stones of Polonnaruwa . In the Moonstones of Anuradhapura , among the animals carved out was an ox. Hindus consider the oxen as sacred. Hence we do not see the ox in the Moon Stones of Polonnaruwa.

Then we moved to see the Samadhi Statue.Samadhi statue is a statue situated at Mahamevuna Park in Anuradhapura, Sri Lanka. It is said that this is one of the best pieces of sculpture. The statue is 8 feet in height and made of granite and the Dhyana mudra is symbolished - The posture of meditation in which Buddha sits in the cross - legged position with upturned palms, placed one over the other on the lap.

 

Then we visited"kuttam Pokuna".One of the best specimen of bathing tanks or pools in ancient Sri Lanka is the pair of pools known as "Kuttam Pokuna" (Twin Ponds/Pools). The said pair of pools were built by the Sinhalese in the ancient kingdom of Anuradhapura. These are considered one of the significant achievements in the field of hydrological engineering and outstanding architectural and artistic creations of the ancient Sinhalese.

A garden was landscaped which separates the two ponds which in length is 18 1/2 ft. The larger pool of the two is 132ft by 51 ft, while the smaller pool is 91ft by 51 ft. The depths of the two pools is 14ft and 18ft for the smaller pool and the larger pool respectively.

The faces of the pools were cut granite slabs which includes the bottom and the sides of the pool. A wall was also built around the pool which encloses the compound. Flights of steps are seen on both ends of the pool decorated with punkalas, or pots of abundance and scroll design. Embankments were constructed to enable monks to bathe using pots or other utensils. Water to the pools were transferred through underground ducts and filtered before flowing to the pool and in a similar fashion the water was emptied.

 

Dr. Senerath Paranavithana was actively involved in the restoration of the ponds, in which small figures of fish, a conch, a crab and a dancing woman were found in the bottom.

With kuttampokuna we left the Ancient city Anuradhapura.Students wanted to have there Lunch on a Tank Dam.So we had our day two lunch on the dam of Nuwara wewa,Anuradhapura.But before lunch we did not forget to feel the breeze and the cold of the water.

By 2 pm day two we finished the Anuradhapura Visiting and left for Sigiriya.Student were curious and active.They took just 1hour to climb up to the Sigiya.Sigiriya (Lion's rock) is an ancient rock fortress and palace ruin situated in the central Matale District of Sri Lanka, surrounded by the remains of an extensive network of gardens, reservoirs, and other structures. A popular tourist destination, Sigiriya is also renowned for its ancient paintings (frescos), which are reminiscent of the Ajanta Caves of India. The Sigiriya was built during the reign of King Kassapa I (AD 477 – 495), and it is one of the seven World Heritage Sites of Sri Lanka.

Sigiriya may have been inhabited through prehistoric times. It was used as a rock-shelter mountain monastery from about the 5th century BC, with caves prepared and donated by devotees to the Buddhist Sangha. The garden and palace were built by King Kasyapa. Following King Kasyapa's death, it was again a monastery complex up to about the 14th century, after which it was abandoned. The ruins were discovered in 1907 by British explorer John Still. The Sigiri inscriptions were deciphered by the archaeologist Senarath Paranavithana in his renowned two-volume work, published by Oxford, Sigiri Graffiti. He also wrote the popular book "Story of Sigiriya".

 

The Mahavamsa, the ancient historical record of Sri Lanka, describes King Kasyapa as the son of King Dhatusena. Kasyapa murdered his father by walling him alive and then usurping the throne which rightfully belonged to his brother Mogallana, Dhatusena's son by the true queen. Mogallana fled to India to escape being assassinated by Kasyapa but vowed revenge. In India he raised an army with the intention of returning and retaking the throne of Sri Lanka which he considered was rightfully his. Knowing the inevitable return of Mogallana, Kasyapa is said to have built his palace on the summit of Sigiriya as a fortress and pleasure palace. Mogallana finally arrived and declared war. During the battle Kasyapa's armies abandoned him and he committed suicide by falling on his sword. Chronicles and lore say that the battle-elephant on which Kasyapa was mounted changed course to take a strategic advantage, but the army misinterpreted the movement as the King having opted to retreat, prompting the army to abandon the king altogether. Moggallana returned the capital to Anuradapura, converting Sigiriya into a monastery complex.

 

Alternative stories have the primary builder of Sigiriya as King Dhatusena, with Kasyapa finishing the work in honour of his father. Still other stories have Kasyapa as a playboy king, with Sigiriya a pleasure palace. Even Kasyapa's eventual fate is mutable. In some versions he is assassinated by poison administered by a concubine. In others he cuts his own throat when isolated in his final battle. Still further interpretations have the site as the work of a Buddhist community, with no military function at all.

 

We did not miss the beauty of sigiriya and to have some pictures of it.After the Sigiriya we Finished day two.Our day two Accommodation was ready @ Royal college Polonnaruwa.it was a nice experience coz all the students should experience a bath in a canal.most of them this was the first time to bath in a canal.

 

In early morning after taking the breakfast and the contained lunch we left to see polonnaruwa,the late kingdom of Sri Lanka.First fo all we went to see the statue of King Parakramabhahu facing the Parakrama Samudraya.it was another master peace of rock carvings.

then we traveled on the Dam of Parakrama Samudraya,the leargest tank of the polonnaruwa,and captured some occasions.We could visit the museum in frat of the Parakrama Samudraya.

After that we left for Dimbulagala.But we saw the Mahaweli river at Manampitiya and the newly built bridge.So we stopped there for the day three lunch.Students got the first chance to have a bath in the Mahaweli River.The water was cald and so clean even the dry season in the polonnaruwa area.it was so hot but still the water of Mahaweli river gave the full satisfaction of having a birth.with in 40 Minutes we finished the bathing and started to have our lunch.Students were very happy to have their lunch on a river bank.Dimbulagala is Another impotent Rock in polonnaruwa.After the lunch we left for Dimbulagala temple and visited the temple.After that we left for Mahiyanganaya.Our aim is to visit the ancient people in Sri lanka and to talk to them.We reached to the Dambana with the dawn an could talk to some Ancient people there.A gang of people there entertained us with some beautiful Veddas dance and songs.

 

After Dambana we went to our day three resting place.We stayed in a resthall at Mahiyanganaya.Like the two previous days cooking and containing food for the day was happened and we went to see mahiyangana Dagoba.Mahiyanganaya is one of a place where the lord Buddha has visited.We could capture the beauty of the dagoba to our lenses.

 

After that we went to see Soraborawewa.Another master piece of Tank technology by Ancient Sri lanken People.At sorabora wewa we went on a cane trip on the river and we found one capable oarsman with us on board.He too joined with other oarsman and took us around the Soraborawewa.

Then we left for Kandy.The road to Kandy to Mahiyanganaya was under construction but our two drivers took us to Kandy by 4.30pm.then we went to see Sri Dalandamaligawa.But on the way we impotent guests there.

 

According to Sri Lankan legends, when the Buddha died, his body was cremated in a sandalwood pyre at Kusinara in India and his left canine tooth was retrieved from the funeral pyre by Arahat Khema. Khema then gave it to King Brahmadatte for veneration. It became a royal possession in Brahmadatte's country and was kept in the city of Dantapuri (present day Puri in Orissa).

 

A belief grew that whoever possessed the Sacred Tooth Relic had a divine right to rule that land. Wars were fought to take possession of the relic. 800 years after the Buddha's death, in the 4th century CE, the tooth came into the possession of King Guhaseeva of Kalinga, which roughly corresponds to the present day state of Orissa.

 

Kalinga had become a Buddhist and begun to worship the Sacred Tooth relic. This caused discontent among some of the citizens, who went to King Paandu and said that King Guhaseeva had stopped believing in god and that he had started to worship a tooth.

 

King Paandu decided to destroy the relic, and ordered to it brought to the city. It is said that, as the tooth arrived at the city, a miracle occurred, and King Paandu converted to Buddhism.

 

When King Ksheeradara heard, he went with his army to attack Paandu in the city of Palalus. The invaders were defeated before reaching the city, and King Ksheeradara died.

 

A prince from the city of Udeni who had become a Buddhist came to worship the sacred tooth. King Guhaseeva was pleased with him, and let him marry his daughter. The prince was known as Dantha and the princess as Hemamala.

 

When they heard that King Ksheeradara had died in the war, his sons raised a large army to attack King Guhaseeva and destroy the relic. They entered the city, but King Guhaseeva secretly sent Dantha and Hemamala out of the city, with the relic.

According to legend, Hemamali hid the relic in her hair ornament and the royal couple disguised themselves as Brahmins in order to avoid discovery. They set sail from Tamralipti, a port at the mouth of the river Ganges, and landed in Sri Lanka at the port of Lankapattana (now Ilankeiturei).

It is said that Sri Lanka was chosen as the new home for the tooth relic because the Lord Buddha had declared that his religion would be safe in Sri Lanka for 2,500 years.[citation needed]

 

At the time of Dantha's and Hemamali's arrival on the island, King Kirti Sri Megavanna or Kithsirimevan ruled Sri Lanka. The King was overjoyed when he heard the news and warmly welcomed the royal couple and received the Sacred Tooth Relic with great veneration. He built a beautiful palace within the Royal Palace Complex itself and enshrined the Relic in it. Thereafter, he ordered that an annual perahera be held in honour of the Sacred Relic.

 

As time went on, as the land was threatened with foreign invasions, the seat of the kingdom was moved from Anuradhapura to Polonnaruwa, then to Dambadeniya and other cities. Upon each change of capital, a new palace was built to enshrine the Relic. Finally, it was brought to Kandy where it is at present, in the Sri Dalada Maligawa temple.

 

The Sacred Tooth Relic came to be regarded as a symbolic representation of the living Buddha and it is on this basis that there grew up a series of offerings, rituals, and ceremonies. These are conducted under the supervision of the two Mahanayake Theros of Malwatte, Asgiriya Chapters, and Diyawadana Nilame of the Maligawa. These have a hierarchy of officials and temple functionaries to perform the services and rituals.

 

Finally we visited the Peradeniya botonical guarden.Royal Botanical Garden, Peradeniya is located in close proximity to the city of Kandy in the Central Province of Sri Lanka. It is renowned for the collection the variety of Orchids,and has more than 300 varieties of Orchids, spices, medicinal plants and palms trees attach it is the National Herbarium. Total land mass of the botanical garden is 147 acres, 460 Meters above sea level with a 200 day annual rain fall, it is managed by the Division of National Botanic Gardens of the Department of Agriculture.

Finally we finished our Annual Excursion with lot of Joy and Knowledge,Experiences and lot more.We would like to thank the Two Rivers who took us all around this Island and parents,Teachers who helped to make this event a success.

The bamboos (Bambusoideae) are a subfamily of flowering perennial evergreen plants in the grass family Poaceae.

 

Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.

 

Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 88.9 Centimeters within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.

 

The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.

 

SYSTEMATICS AND TAXONOMY

The bamboos have long been considered the most primitive grasses, mostly because of the presence of bracteate, indeterminate inflorescences, "pseudospikelets", and flowers with three lodicules, six stamens, and three stigmas. Following more recent molecular phylogenetic research, many tribes and genera of grasses formerly included in Bambusoideae are now classified in other subfamilies, e.g. the Anomochlooideae, the Puelioideae, and the Ehrhartoideae. The subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae (bluegrasses and relatives).

 

The bamboos contains three clades classified as tribes, and these strongly correspond with geographic divisions, representing the New World herbaceous species (Olyreae), tropical woody bamboos (Bambuseae) and temperate woody bamboos (Arundinarieae). The woody bamboos do not form a monophyletic group; instead, the tropical woody and herbaceous bamboos are sister to the temperate woody bamboos. Altogether, there are more than 1,400 species in 115 genera.

 

Tribe Olyreae (herbaceous bamboos)

Tribe Bambuseae (tropical woody bamboos)

Tribe Arundinarieae (temperate woody bamboos)

 

DISTRIBUTION

Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. They occur across East Asia, from 50°N latitude in Sakhalin through to Northern Australia, and west to India and the Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the mid-Atlantic states south to Argentina and Chile, reaching their southernmost point at 47°S latitude. Continental Europe is not known to have any native species of bamboo.

 

Recently, some attempts have been made to grow bamboo on a commercial basis in the Great Lakes region of east-central Africa, especially in Rwanda. In the United States, several companies are growing, harvesting, and distributing species such as Phyllostachys nigra (Henon) and Phyllostachys edulis (Moso).

 

ECOLOGY

Bamboo is one of the fastest-growing plants on Earth, with reported growth rates of 250 cm in 24 hours. However, the growth rate is dependent on local soil and climatic conditions, as well as species, and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of 3–10 centimetre per day during the growing period. Primarily growing in regions of warmer climates during the late Cretaceous period, vast fields existed in what is now Asia. Some of the largest timber bamboo can grow over 30 m tall, and be as large as 15–20 cm in diameter. However, the size range for mature bamboo is species dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4.6–12 metres, depending on species. Anji County of China, known as the "Town of Bamboo", provides the optimal climate and soil conditions to grow, harvest, and process some of the most valued bamboo poles available worldwide.

 

Unlike all trees, individual bamboo stems, or culms, emerge from the ground at their full diameter and grow to their full height in a single growing season of three to four months. During these several months, each new shoot grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens. During the third year, the culm hardens further. The shoot is now considered a fully mature culm. Over the next 2–5 years (depending on species), fungus begins to form on the outside of the culm, which eventually penetrates and overcomes the culm. Around 5–8 years later (species and climate dependent), the fungal growths cause the culm to collapse and decay. This brief life means culms are ready for harvest and suitable for use in construction within about three to seven years. Individual bamboo culms do not get any taller or larger in diameter in subsequent years than they do in their first year, and they do not replace any growth lost from pruning or natural breakage. Bamboos have a wide range of hardiness depending on species and locale. Small or young specimens of an individual species will produce small culms initially. As the clump and its rhizome system mature, taller and larger culms will be produced each year until the plant approaches its particular species limits of height and diameter.

 

Many tropical bamboo species will die at or near freezing temperatures, while some of the hardier or so-called temperate bamboos can survive temperatures as low as −29 °C. Some of the hardiest bamboo species can be grown in places as cold as USDA Plant Hardiness Zones 5–6, although they typically will defoliate and may even lose all above-ground growth, yet the rhizomes will survive and send up shoots again the next spring. In milder climates, such as USDA Zone 8 and above, some hardy bamboo may remain fully leafed out year-round.

 

MASS FLOWERING

Most bamboo species flower infrequently. In fact, many bamboos only flower at intervals as long as 65 or 120 years. These taxa exhibit mass flowering (or gregarious flowering), with all plants in a particular cohort flowering over a several-year period. Any plant derived through clonal propagation from this cohort will also flower regardless of whether it has been planted in a different location. The longest mass flowering interval known is 130 years, and it is for the species Phyllostachys bambusoides (Sieb. & Zucc.). In this species, all plants of the same stock flower at the same time, regardless of differences in geographic locations or climatic conditions, and then the bamboo dies. The lack of environmental impact on the time of flowering indicates the presence of some sort of "alarm clock" in each cell of the plant which signals the diversion of all energy to flower production and the cessation of vegetative growth. This mechanism, as well as the evolutionary cause behind it, is still largely a mystery.

 

One hypothesis to explain the evolution of this semelparous mass flowering is the predator satiation hypothesis which argues that by fruiting at the same time, a population increases the survival rate of their seeds by flooding the area with fruit, so, even if predators eat their fill, seeds will still be left over. By having a flowering cycle longer than the lifespan of the rodent predators, bamboos can regulate animal populations by causing starvation during the period between flowering events. Thus the death of the adult clone is due to resource exhaustion, as it would be more effective for parent plants to devote all resources to creating a large seed crop than to hold back energy for their own regeneration.

 

Another, the fire cycle hypothesis, argues that periodic flowering followed by death of the adult plants has evolved as a mechanism to create disturbance in the habitat, thus providing the seedlings with a gap in which to grow. This argues that the dead culms create a large fuel load, and also a large target for lightning strikes, increasing the likelihood of wildfire. Because bamboos can be aggressive as early successional plants, the seedlings would be able to outstrip other plants and take over the space left by their parents.

 

However, both have been disputed for different reasons. The predator satiation hypothesis does not explain why the flowering cycle is 10 times longer than the lifespan of the local rodents, something not predicted. The bamboo fire cycle hypothesis is considered by a few scientists to be unreasonable; they argue[20] that fires only result from humans and there is no natural fire in India. This notion is considered wrong based on distribution of lightning strike data during the dry season throughout India. However, another argument against this is the lack of precedent for any living organism to harness something as unpredictable as lightning strikes to increase its chance of survival as part of natural evolutionary progress.

 

More recently, a mathematical explanation for the extreme length of the flowering cycles has been offered, involving both the stabilizing selection implied by the predator satiation hypothesis and others, and the fact that plants that flower at longer intervals tend to release more seeds. The hypothesis claims that bamboo flowering intervals grew by integer multiplication. A mutant bamboo plant flowering at a non-integer multiple of its population's flowering interval would release its seeds alone, and would not enjoy the benefits of collective flowering (such as protection from predators). On the other hand, a mutant bamboo plant flowering at an integer multiple of its population's flowering interval would release its seeds only during collective flowering events, and would release more seeds than the average plant in the population. It could therefore take over the population, establishing a flowering interval that is an integer multiple of the previous flowering interval. The hypothesis predicts that observed bamboo flowering intervals should factorize into small prime numbers.

 

The mass fruiting also has direct economic and ecological consequences, however. The huge increase in available fruit in the forests often causes a boom in rodent populations, leading to increases in disease and famine in nearby human populations. For example, devastating consequences occur when the Melocanna bambusoides population flowers and fruits once every 30–35 years around the Bay of Bengal. The death of the bamboo plants following their fruiting means the local people lose their building material, and the large increase in bamboo fruit leads to a rapid increase in rodent populations. As the number of rodents increases, they consume all available food, including grain fields and stored food, sometimes leading to famine. These rats can also carry dangerous diseases, such as typhus, typhoid, and bubonic plague, which can reach epidemic proportions as the rodents increase in number. The relationship between rat populations and bamboo flowering was examined in a 2009 Nova documentary "Rat Attack".

 

In any case, flowering produces masses of seeds, typically suspended from the ends of the branches. These seeds will give rise to a new generation of plants that may be identical in appearance to those that preceded the flowering, or they may produce new cultivars with different characteristics, such as the presence or absence of striping or other changes in coloration of the culms.

 

Several bamboo species are never known to set seed even when sporadically flowering has been reported. Bambusa vulgaris, Bambusa balcooa and Dendrocalamus stocksii are common examples of such bamboo.

 

AS ANIMAL DIET

Soft bamboo shoots, stems, and leaves are the major food source of the giant panda of China, the red panda of Nepal and the bamboo lemurs of Madagascar. Rats will eat the fruits as described above. Mountain gorillas of Africa also feed on bamboo, and have been documented consuming bamboo sap which was fermented and alcoholic; chimpanzees and elephants of the region also eat the stalks.

 

The larvae of the bamboo borer (the moth Omphisa fuscidentalis) of Laos, Myanmar, Thailand and Yunnan Province, China, feeds off the pulp of live bamboo. In turn, these caterpillars are considered a local delicacy.

 

CULTIVATION

COMMERCIAL TIMBER

Timber is harvested from both cultivated and wild stands, and some of the larger bamboos, particularly species in the genus Phyllostachys, are known as "timber bamboos".

 

HARVESTING

Bamboo used for construction purposes must be harvested when the culms reach their greatest strength and when sugar levels in the sap are at their lowest, as high sugar content increases the ease and rate of pest infestation.

 

Harvesting of bamboo is typically undertaken according to the following cycles:

 

1) Life cycle of the culm: As each individual culm goes through a 5– to 7-year life cycle, culms are ideally allowed to reach this level of maturity prior to full capacity harvesting. The clearing out or thinning of culms, particularly older decaying culms, helps to ensure adequate light and resources for new growth. Well-maintained clumps may have a productivity three to four times that of an unharvested wild clump. Consistent with the life cycle described above, bamboo is harvested from two to three years through to five to seven years, depending on the species.

 

2) Annual cycle: As all growth of new bamboo occurs during the wet season, disturbing the clump during this phase will potentially damage the upcoming crop. Also during this high rainfall period, sap levels are at their highest, and then diminish towards the dry season. Picking immediately prior to the wet/growth season may also damage new shoots. Hence, harvesting is best a few months prior to the start of the wet season.

 

3) Daily cycle: During the height of the day, photosynthesis is at its peak, producing the highest levels of sugar in sap, making this the least ideal time of day to harvest. Many traditional practitioners believe the best time to harvest is at dawn or dusk on a waning moon.

 

LEACHING

Leaching is the removal of sap after harvest. In many areas of the world, the sap levels in harvested bamboo are reduced either through leaching or postharvest photosynthesis.

 

EXEMPLES OF THIS PRACTICE INCLUDE:

Cut bamboo is raised clear of the ground and leaned against the rest of the clump for one to two weeks until leaves turn yellow to allow full consumption of sugars by the plant.

A similar method is undertaken, but with the base of the culm standing in fresh water, either in a large drum or stream to leach out sap.

Cut culms are immersed in a running stream and weighted down for three to four weeks.

Water is pumped through the freshly cut culms, forcing out the sap (this method is often used in conjunction with the injection of some form of treatment).

 

In the process of water leaching, the bamboo is dried slowly and evenly in the shade to avoid cracking in the outer skin of the bamboo, thereby reducing opportunities for pest infestation.

 

Durability of bamboo in construction is directly related to how well it is handled from the moment of planting through harvesting, transportation, storage, design, construction and maintenance. Bamboo harvested at the correct time of year and then exposed to ground contact or rain, will break down just as quickly as incorrectly harvested material.

 

ORNAMENTAL BAMBOOS

The two general patterns for the growth of bamboo are "clumping" (sympodial) and "running" (monopodial). Clumping bamboo species tend to spread slowly, as the growth pattern of the rhizomes is to simply expand the root mass gradually, similar to ornamental grasses. "Running" bamboos, on the other hand, need to be controlled during cultivation because of their potential for aggressive behavior. They spread mainly through their roots and/or rhizomes, which can spread widely underground and send up new culms to break through the surface. Running bamboo species are highly variable in their tendency to spread; this is related to both the species and the soil and climate conditions. Some can send out runners of several metres a year, while others can stay in the same general area for long periods. If neglected, over time they can cause problems by moving into adjacent areas.

 

Bamboos seldom and unpredictably flower, and the frequency of flowering varies greatly from species to species. Once flowering takes place, a plant will decline and often die entirely. Although there are always a few species of bamboo in flower at any given time, collectors desiring to grow specific bamboo typically obtain their plants as divisions of already-growing plants, rather than waiting for seeds to be produced.

 

Regular observations will indicate major growth directions and locations. Once the rhizomes are cut, they are typically removed; however, rhizomes take a number of months to mature, and an immature, severed rhizome will usually cease growing if left in-ground. If any bamboo shoots come up outside of the bamboo area afterwards, their presence indicates the precise location of the removed rhizome. The fibrous roots that radiate from the rhizomes do not produce more bamboo.

 

Bamboo growth is also controlled by surrounding the plant or grove with a physical barrier. Typically, concrete and specially rolled HDPE plastic are the materials used to create the barrier, which is placed in a 60– to 90-cm-deep ditch around the planting, and angled out at the top to direct the rhizomes to the surface. (This is only possible if the barrier is installed in a straight line.) If the containment area is small, this method can be detrimental to ornamental bamboo, as the bamboo within can become rootbound and start to display the signs of any unhealthy containerized plant. In addition, rhizomes can escape over the top, or beneath the barrier if it is not deep enough. Strong rhizomes and tools can penetrate plastic barriers, so care must be taken. In small areas, regular maintenance may be the best method for controlling the running bamboos. Barriers and edging are unnecessary for clump-forming bamboos, although these may eventually need to have portions removed if they become too large.

 

The ornamental plant sold in containers and marketed as "lucky bamboo" is actually an entirely unrelated plant, Dracaena sanderiana. It is a resilient member of the lily family that grows in the dark, tropical rainforests of Southeast Asia and Africa. Lucky bamboo has long been associated with the Eastern practice of feng shui and images of the plant widely available on the Web are often used to depict bamboo. On a similar note, Japanese knotweed is also sometimes mistaken for a bamboo, but it grows wild and is considered an invasive species. Phyllostachys species of bamboo are also considered invasive and illegal to sell or propagate in some areas of the US.

 

USES

CULINARY

Although the shoots (new culms that come out of the ground) of bamboo contain a toxin taxiphyllin (a cyanogenic glycoside) that produces cyanide in the gut, proper processing renders them edible. They are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh and canned versions. The golden bamboo lemur ingests many times the quantity of the taxiphyllin-containing bamboo that would kill a human.

 

The bamboo shoot in its fermented state forms an important ingredient in cuisines across the Himalayas. In Assam, India, for example, it is called khorisa. In Nepal, a delicacy popular across ethnic boundaries consists of bamboo shoots fermented with turmeric and oil, and cooked with potatoes into a dish that usually accompanies rice (alu tama (आलु तामा) in Nepali).

 

In Indonesia, they are sliced thin and then boiled with santan (thick coconut milk) and spices to make a dish called gulai rebung. Other recipes using bamboo shoots are sayur lodeh (mixed vegetables in coconut milk) and lun pia (sometimes written lumpia: fried wrapped bamboo shoots with vegetables). The shoots of some species contain toxins that need to be leached or boiled out before they can be eaten safely.

 

Pickled bamboo, used as a condiment, may also be made from the pith of the young shoots.

 

The sap of young stalks tapped during the rainy season may be fermented to make ulanzi (a sweet wine) or simply made into a soft drink. Bamboo leaves are also used as wrappers for steamed dumplings which usually contains glutinous rice and other ingredients.

 

Pickled bamboo shoots (Nepali:तामा tama) are cooked with black-eyed beans as a delicacy food in Nepal. Many Nepalese restaurant around the world serve this dish as aloo bodi tama. Fresh bamboo shoots are sliced and pickled with mustard seeds and turmeric and kept in glass jar in direct sunlight for the best taste. It is used alongside many dried beans in cooking during winter months. Baby shoots (Nepali: tusa) of a very different variety of bamboo (Nepali: निगालो Nigalo) native to Nepal is cooked as a curry in Hilly regions.

 

In Sambalpur, India, the tender shoots are grated into juliennes and fermented to prepare kardi. The name is derived from the Sanskrit word for bamboo shoot, karira. This fermented bamboo shoot is used in various culinary preparations, notably amil, a sour vegetable soup. It is also made into pancakes using rice flour as a binding agent. The shoots that have turned a little fibrous are fermented, dried, and ground to sand-sized particles to prepare a garnish known as hendua. It is also cooked with tender pumpkin leaves to make sag green leaves.

 

In Konkani cuisine, the tender shoots (kirlu) are grated and cooked with crushed jackfruit seeds to prepare 'kirla sukke'.

 

The empty hollow in the stalks of larger bamboo is often used to cook food in many Asian cultures. Soups are boiled and rice is cooked in the hollows of fresh stalks of bamboo directly over a flame. Similarly, steamed tea is sometimes rammed into bamboo hollows to produce compressed forms of Pu-erh tea. Cooking food in bamboo is said to give the food a subtle but distinctive taste.

 

In addition, bamboo is frequently used for cooking utensils within many cultures, and is used in the manufacture of chopsticks. In modern times, some see bamboo tools as an ecofriendly alternative to other manufactured utensils.

 

MEDICINE

Bamboo is used in Chinese medicine for treating infections and healing. In northern Indian state of Assam, the fermented bamboo paste known as khorisa is known locally as a folk remedy for the treatment of impotence, infertility, and menstrual pains.

 

CONSTRUCTION

Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.

 

In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.

 

Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong. In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support. In Japanese architecture, bamboo is used primarily as a supplemental and/or decorative element in buildings such as fencing, fountains, grates and gutters, largely due to the ready abundance of quality timber.

 

Various structural shapes may be made by training the bamboo to assume them as it grows. Squared sections of bamboo are created by compressing the growing stalk within a square form. Arches may similarly be created by forcing the bamboo's growth into the desired form, costing much less than it would to obtain the same shape with regular wood timber. More traditional forming methods, such as the application of heat and pressure, may also be used to curve or flatten the cut stalks.

 

Bamboo can be cut and laminated into sheets and planks. This process involves cutting stalks into thin strips, planing them flat, and boiling and drying the strips; they are then glued, pressed and finished. Long used in China and Japan, entrepreneurs started developing and selling laminated bamboo flooring in the West during the mid-1990s; products made from bamboo laminate, including flooring, cabinetry, furniture and even decorations, are currently surging in popularity, transitioning from the boutique market to mainstream providers such as Home Depot. The bamboo goods industry (which also includes small goods, fabric, etc.) is expected to be worth $25 billion by 2012. The quality of bamboo laminate varies among manufacturers and varies according to the maturity of the plant from which it was harvested (six years being considered the optimum); the sturdiest products fulfill their claims of being up to three times harder than oak hardwood while others may be softer than standard hardwood.

 

Bamboo intended for use in construction should be treated to resist insects and rot. The most common solution for this purpose is a mixture of borax and boric acid. Another process involves boiling cut bamboo to remove the starches that attract insects.

 

Bamboo has been used as reinforcement for concrete in those areas where it is plentiful, though dispute exists over its effectiveness in the various studies done on the subject. Bamboo does have the necessary strength to fulfil this function, but untreated bamboo will swell with water absorbed from the concrete, causing it to crack. Several procedures must be followed to overcome this shortcoming.

 

Several institutes, businesses, and universities are researching the use of bamboo as an ecological construction material. In the United States and France, it is possible to get houses made entirely of bamboo,[citation needed] which are earthquake- and cyclone-resistant and internationally certified. In Bali, Indonesia, an international K-12 school, the Green School, is constructed entirely of bamboo, for its beauty and advantages as a sustainable resource. There are three ISO standards for bamboo as a construction material.

 

In parts of India, bamboo is used for drying clothes indoors, both as a rod high up near the ceiling to hang clothes on, and as a stick wielded with acquired expert skill to hoist, spread, and to take down the clothes when dry. It is also commonly used to make ladders, which apart from their normal function, are also used for carrying bodies in funerals. In Maharashtra, the bamboo groves and forests are called Veluvana, the name velu for bamboo is most likely from Sanskrit, while vana means forest.

 

Furthermore, bamboo is also used to create flagpoles for saffron-coloured, Hindu religious flags, which can be seen fluttering across India, especially in Bihar and Uttar Pradesh, as well as in Guyana and Suriname in South America.

 

Bamboo was used for the structural members of the India pavilion at Expo 2010 in Shanghai. The pavilion is the world’s largest bamboo dome, about 34 m in diameter, with bamboo beams/members overlaid with a ferro-concrete slab, waterproofing, copper plate, solar PV panels, a small windmill, and live plants. A total of 30 km of bamboo was used. The dome is supported on 18-m-long steel piles and a series of steel ring beams. The bamboo was treated with borax and boric acid as a fire retardant and insecticide and bent in the required shape. The bamboo sections were joined with reinforcement bars and concrete mortar to achieve the necessary lengths.

 

TEXTILES

Since the fibers of bamboo are very short (less than 3 mm), they are not usually transformed into yarn by a natural process. The usual process by which textiles labeled as being made of bamboo are produced uses only rayon made from the fibers with heavy employment of chemicals. To accomplish this, the fibers are broken down with chemicals and extruded through mechanical spinnerets; the chemicals include lye, carbon disulfide and strong acids. Retailers have sold both end products as "bamboo fabric" to cash in on bamboo's current ecofriendly cachet; however, the Canadian Competition Bureau and the US Federal Trade Commission, as of mid-2009, are cracking down on the practice of labeling bamboo rayon as natural bamboo fabric. Under the guidelines of both agencies, these products must be labeled as rayon with the optional qualifier "from bamboo".

 

AS A WRITING SURFACE

Bamboo was in widespread use in early China as a medium for written documents. The earliest surviving examples of such documents, written in ink on string-bound bundles of bamboo strips (or "slips"), date from the fifth century BC during the Warring States period. However, references in earlier texts surviving on other media make it clear that some precursor of these Warring States period bamboo slips was in use as early as the late Shang period (from about 1250 BC).

 

Bamboo or wooden strips were the standard writing material during the Han dynasty, and excavated examples have been found in abundance. Subsequently, paper began to displace bamboo and wooden strips from mainstream uses, and by the fourth century AD, bamboo slips had been largely abandoned as a medium for writing in China. Several paper industries are surviving on bamboo forests. Ballarpur (Chandrapur, Maharstra) paper mills use bamboo for paper production.

 

Bamboo fiber has been used to make paper in China since early times. A high-quality, handmade paper is still produced in small quantities. Coarse bamboo paper is still used to make spirit money in many Chinese communities.

 

Bamboo pulps are mainly produced in China, Myanmar, Thailand and India, and are used in printing and writing papers. The most common bamboo species used for paper are Dendrocalamus asper and Bamboo bluemanea. It is also possible to make dissolving pulp from bamboo. The average fiber length is similar to hardwoods, but the properties of bamboo pulp are closer to softwood pulps due to it having a very broad fiber length distribution. With the help of molecular tools, it is now possible to distinguish the superior fiber-yielding species/varieties even at juvenile stages of their growth, which can help in unadulterated merchandise production.[

 

WEAPONS

Bamboo has often been used to construct weapons and is still incorporated in several Asian martial arts.

 

A bamboo staff, sometimes with one end sharpened, is used in the Tamil martial art of silambam, a word derived from a term meaning "hill bamboo".

Staves used in the Indian martial art of gatka are commonly made from bamboo, a material favoured for its light weight.

A bamboo sword called a shinai is used in the Japanese martial art of kendo.

Bamboo is used for crafting the bows, called yumi, and arrows used in the Japanese martial art kyudo.

Bamboo is sometimes used to craft the limbs of the longbow and recurve bow used in traditional archery, and to make superior weapons for bowhunting and target archery.

The first gunpowder-based weapons, such as the fire lance, were made of bamboo.

Bamboo was apparently used in East and South Asia as a means of torture.

 

OTHER USES

Bamboo has traditionally been used to make a wide range of everyday utensils, particularly in Japan, where archaeological excavations have uncovered bamboo baskets dating to the Late Jomon period (2000–1000 BC).

 

Bamboo has a long history of use in Asian furniture. Chinese bamboo furniture is a distinct style based on a millennia-long tradition.

 

Several manufacturers offer bamboo bicycles, surfboards, snowboards, and skateboards.

 

Due to its flexibility, bamboo is also used to make fishing rods. The split cane rod is especially prized for fly fishing. Bamboo has been traditionally used in Malaysia as a firecracker called a meriam buluh or bamboo cannon. Four-foot-long sections of bamboo are cut, and a mixture of water and calcium carbide are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang. Bamboo can be used in water desalination. A bamboo filter is used to remove the salt from seawater.

 

Food is cooked in East Timor in bamboo in fire. This is called Tukir.

 

Many minority groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, 6–7 metres long, laid together side by side to a width of about 1 metre. Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water. Bamboo is also used to make eating utensils such as chop sticks, trays, and tea scoops.

 

The Song Dynasty (960–1279 AD) Chinese scientist and polymath Shen Kuo (1031–1095) used the evidence of underground petrified bamboo found in the dry northern climate of Yan'an, Shanbei region, Shaanxi province to support his geological theory of gradual climate change.

 

SYMBOLISM AND CULTURE

Bamboo's long life makes it a Chinese symbol of uprightness, while in India it is a symbol of friendship. The rarity of its blossoming has led to the flowers' being regarded as a sign of impending famine. This may be due to rats feeding upon the profusion of flowers, then multiplying and destroying a large part of the local food supply. The most recent flowering began in May 2006 (see Mautam). Bamboo is said to bloom in this manner only about every 50 years (see 28–60 year examples in FAO: 'gregarious' species table).

 

In Chinese culture, the bamboo, plum blossom, orchid, and chrysanthemum (often known as méi lán zhú jú 梅兰竹菊) are collectively referred to as the Four Gentlemen. These four plants also represent the four seasons and, in Confucian ideology, four aspects of the junzi ("prince" or "noble one"). The pine (sōng 松), the bamboo (zhú 竹), and the plum blossom (méi 梅) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends of Winter" (岁寒三友 suìhán sānyǒu) in Chinese culture. The "Three Friends of Winter" is traditionally used as a system of ranking in Japan, for example in sushi sets or accommodations at a traditional ryokan. Pine (matsu 松) is of the first rank, bamboo (také 竹) is of second rank, and plum (ume 梅) is of the third.

 

The Bozo ethnic group of West Africa take their name from the Bambara phrase bo-so, which means "bamboo house". Bamboo is also the national plant of St. Lucia.

 

BAMBOO, NOBLE AND USEFUL

Bamboo, one of the "Four Gentlemen" (bamboo, orchid, plum blossom and chrysanthemum), plays such an important role in traditional Chinese culture that it is even regarded as a behavior model of the gentleman. As bamboo has features such as uprightness, tenacity, and hollow heart, people endow bamboo with integrity, elegance, and plainness, though it is not physically strong. Countless poems praising bamboo written by ancient Chinese poets are actually metaphorically about people who exhibited these characteristics. According to laws, an ancient poet, Bai Juyi (772–846), thought that to be a gentleman, a man does not need to be physically strong, but he must be mentally strong, upright, and perseverant. Just as a bamboo is hollow-hearted, he should open his heart to accept anything of benefit and never have arrogance or prejudice. Bamboo is not only a symbol of a gentleman, but also plays an important role in Buddhism, which was introduced into China in the first century. As canons of Buddhism forbids cruelty to animals, flesh and egg were not allowed in the diet. The tender bamboo shoot (sǔn筍 in Chinese) thus became a nutritious alternative. Preparation methods developed over thousands of years have come to incorporated into Asian cuisines, especially for monks. A Buddhist monk, Zan Ning, wrote a manual of the bamboo shoot called "Sǔn Pǔ筍譜" offering descriptions and recipes for many kinds of bamboo shoots. Bamboo shoot has always been a traditional dish on the Chinese dinner table, especially in southern China. In ancient times, those who could afford a big house with a yard would plant bamboo in their garden.

 

In Japan, a bamboo forest sometimes surrounds a Shinto shrine as part of a sacred barrier against evil. Many Buddhist temples also have bamboo groves.

 

Bamboo plays an important part of the culture of Vietnam. Bamboo symbolizes the spirit of Vovinam (a Vietnamese martial arts): cương nhu phối triển (coordination between hard and soft (martial arts)). Bamboo also symbolizes the Vietnamese hometown and Vietnamese soul: the gentlemanlike, straightforwardness, hard working, optimism, unity, and adaptability. A Vietnamese proverb says, "When the bamboo is old, the bamboo sprouts appear", the meaning being Vietnam will never be annihilated; if the previous generation dies, the children take their place. Therefore, the Vietnam nation and Vietnamese value will be maintained and developed eternally. Traditional Vietnamese villages are surrounded by thick bamboo hedges (lũy tre).

 

IN MYTHOLOGY

Several Asian cultures, including that of the Andaman Islands, believe humanity emerged from a bamboo stem.

 

In Philippine mythology, one of the more famous creation accounts tells of the first man, Malakás ("Strong"), and the first woman, Maganda ("Beautiful"), each emerged from one half of a split bamboo stem on an island formed after the battle between Sky and Ocean. In Malaysia, a similar story includes a man who dreams of a beautiful woman while sleeping under a bamboo plant; he wakes up and breaks the bamboo stem, discovering the woman inside. The Japanese folktale "Tale of the Bamboo Cutter" (Taketori Monogatari) tells of a princess from the Moon emerging from a shining bamboo section. Hawaiian bamboo ('ohe) is a kinolau or body form of the Polynesian creator god Kāne.

 

A bamboo cane is also the weapon of Vietnamese legendary hero, Saint Giong, who had grown up immediately and magically since the age of three because of his wish to liberate his land from Ân invaders. An ancient Vietnamese legend (The Hundred-knot Bamboo Tree) tells of a poor, young farmer who fell in love with his landlord's beautiful daughter. The farmer asked the landlord for his daughter's hand in marriage, but the proud landlord would not allow her to be bound in marriage to a poor farmer. The landlord decided to foil the marriage with an impossible deal; the farmer must bring him a "bamboo tree of 100 nodes". But Gautama Buddha (Bụt) appeared to the farmer and told him that such a tree could be made from 100 nodes from several different trees. Bụt gave to him four magic words to attach the many nodes of bamboo: Khắc nhập, khắc xuất, which means "joined together immediately, fell apart immediately". The triumphant farmer returned to the landlord and demanded his daughter. Curious to see such a long bamboo, the landlord was magically joined to the bamboo when he touched it, as the young farmer said the first two magic words. The story ends with the happy marriage of the farmer and the landlord's daughter after the landlord agreed to the marriage and asked to be separated from the bamboo.

 

In a Chinese legend, the Emperor Yao gave two of his daughters to the future Emperor Shun as a test for his potential to rule. Shun passed the test of being able to run his household with the two emperor's daughters as wives, and thus Yao made Shun his successor, bypassing his unworthy son. Later, Shun drowned in the Xiang River. The tears his two bereaved wives let fall upon the bamboos growing there explains the origin of spotted bamboo. The two women later became goddesses.

The DQ class locomotives are a class of mainline diesel-electric locomotives in New Zealand and Tasmania, Australia.

Originally Queensland Rail 1460 and 1502 class, they were purchased by New Zealand Rail Limited in 1995 to be rebuilt, as a cheaper alternative to buying new locomotives.

They arrived in New Zealand as the QR classes 1460 and 1502, most of which were then rebuilt by Hutt Workshops into the DQ class. During rebuilding their cabs were modified with the addition of two large windows, short hood lowered, a computerised control system installed, upgrading of the engines, fitting of dynamic brakes and the addition of noise insulation. The QR locomotives that were not rebuilt received only minimal alteration before being used as trailing locomotives. All were painted in Tranz Rail's corporate livery of light blue and yellow before being put into service.

They are not favoured however by their crews due to complaints of rough riding and excessive cab noise.

They are also considered unreliable by senior management (DQ units in Tasmania have a high rate of generator failure), so they are now mainly used for short-haul runs, such as on the final leg of coal trains from the West Coast between Christchurch and the port of Lyttelton and on the Ohai Branch Line to and from Invercargill, hauling containerized coal trains. They are also used as bankers to help trains up the steep grade out of Picton.

As of 2011, there were only three DQ locomotives in service (all in the South Island); the remaining QR units that were not rebuilt have been sold after lengthy periods of storage at the Hutt Workshops. DQ 6347 suffered damage when toppled onto its side after derailing on entry to the Picton yard in late 2009, after which it was sent to Hutt Workshops for repair. It remained out-of service with little work undertaken on it for months but was eventually repaired and returned to service in October 2011. DQ 6376 is currently out of service after it was derailed when the freight train it was part of struck a slip south of Kaikoura in June 2011. In both cases the DQ was operating as the trailing locomotive (in multiple with another) and unoccupied at the time of derailment.

In 1998 Tranz Rail began to export locomotives to Tasmania for use on TasRail, then part-owned by Tranz Rail. In total, twelve DQ were exported, along with three unrebuilt QR class. On 2 September 1998 the first two locomotives in the planned replacement of Tasmania’s mainly English Electric locomotive fleet arrived in Tasmania from New Zealand. The first GM-powered locomotives in Tasmania were originally two ex-Queensland Railways 1502 class purchased by Tranz Rail for use in New Zealand in 1996. All DQ class locomotives were rebuilt and modified at Tranz Rail’s Hutt workshops at Wellington, before being shipped to Tasmania.

Most recent report on this locomotive is that it is operated by a cement company to work at a site near the Nacala Corridor in Mozambique as RRL22-02.

The bamboos (Bambusoideae) are a subfamily of flowering perennial evergreen plants in the grass family Poaceae.

 

Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering.

 

Bamboos are some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow 88.9 Centimeters within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.

 

The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.

 

SYSTEMATICS AND TAXONOMY

The bamboos have long been considered the most primitive grasses, mostly because of the presence of bracteate, indeterminate inflorescences, "pseudospikelets", and flowers with three lodicules, six stamens, and three stigmas. Following more recent molecular phylogenetic research, many tribes and genera of grasses formerly included in Bambusoideae are now classified in other subfamilies, e.g. the Anomochlooideae, the Puelioideae, and the Ehrhartoideae. The subfamily in its current sense belongs to the BOP clade of grasses, where it is sister to the Pooideae (bluegrasses and relatives).

 

The bamboos contains three clades classified as tribes, and these strongly correspond with geographic divisions, representing the New World herbaceous species (Olyreae), tropical woody bamboos (Bambuseae) and temperate woody bamboos (Arundinarieae). The woody bamboos do not form a monophyletic group; instead, the tropical woody and herbaceous bamboos are sister to the temperate woody bamboos. Altogether, there are more than 1,400 species in 115 genera.

 

Tribe Olyreae (herbaceous bamboos)

Tribe Bambuseae (tropical woody bamboos)

Tribe Arundinarieae (temperate woody bamboos)

 

DISTRIBUTION

Bamboo species are found in diverse climates, from cold mountains to hot tropical regions. They occur across East Asia, from 50°N latitude in Sakhalin through to Northern Australia, and west to India and the Himalayas. They also occur in sub-Saharan Africa, and in the Americas from the mid-Atlantic states south to Argentina and Chile, reaching their southernmost point at 47°S latitude. Continental Europe is not known to have any native species of bamboo.

 

Recently, some attempts have been made to grow bamboo on a commercial basis in the Great Lakes region of east-central Africa, especially in Rwanda. In the United States, several companies are growing, harvesting, and distributing species such as Phyllostachys nigra (Henon) and Phyllostachys edulis (Moso).

 

ECOLOGY

Bamboo is one of the fastest-growing plants on Earth, with reported growth rates of 250 cm in 24 hours. However, the growth rate is dependent on local soil and climatic conditions, as well as species, and a more typical growth rate for many commonly cultivated bamboos in temperate climates is in the range of 3–10 centimetre per day during the growing period. Primarily growing in regions of warmer climates during the late Cretaceous period, vast fields existed in what is now Asia. Some of the largest timber bamboo can grow over 30 m tall, and be as large as 15–20 cm in diameter. However, the size range for mature bamboo is species dependent, with the smallest bamboos reaching only several inches high at maturity. A typical height range that would cover many of the common bamboos grown in the United States is 4.6–12 metres, depending on species. Anji County of China, known as the "Town of Bamboo", provides the optimal climate and soil conditions to grow, harvest, and process some of the most valued bamboo poles available worldwide.

 

Unlike all trees, individual bamboo stems, or culms, emerge from the ground at their full diameter and grow to their full height in a single growing season of three to four months. During these several months, each new shoot grows vertically into a culm with no branching out until the majority of the mature height is reached. Then, the branches extend from the nodes and leafing out occurs. In the next year, the pulpy wall of each culm slowly hardens. During the third year, the culm hardens further. The shoot is now considered a fully mature culm. Over the next 2–5 years (depending on species), fungus begins to form on the outside of the culm, which eventually penetrates and overcomes the culm. Around 5–8 years later (species and climate dependent), the fungal growths cause the culm to collapse and decay. This brief life means culms are ready for harvest and suitable for use in construction within about three to seven years. Individual bamboo culms do not get any taller or larger in diameter in subsequent years than they do in their first year, and they do not replace any growth lost from pruning or natural breakage. Bamboos have a wide range of hardiness depending on species and locale. Small or young specimens of an individual species will produce small culms initially. As the clump and its rhizome system mature, taller and larger culms will be produced each year until the plant approaches its particular species limits of height and diameter.

 

Many tropical bamboo species will die at or near freezing temperatures, while some of the hardier or so-called temperate bamboos can survive temperatures as low as −29 °C. Some of the hardiest bamboo species can be grown in places as cold as USDA Plant Hardiness Zones 5–6, although they typically will defoliate and may even lose all above-ground growth, yet the rhizomes will survive and send up shoots again the next spring. In milder climates, such as USDA Zone 8 and above, some hardy bamboo may remain fully leafed out year-round.

 

MASS FLOWERING

Most bamboo species flower infrequently. In fact, many bamboos only flower at intervals as long as 65 or 120 years. These taxa exhibit mass flowering (or gregarious flowering), with all plants in a particular cohort flowering over a several-year period. Any plant derived through clonal propagation from this cohort will also flower regardless of whether it has been planted in a different location. The longest mass flowering interval known is 130 years, and it is for the species Phyllostachys bambusoides (Sieb. & Zucc.). In this species, all plants of the same stock flower at the same time, regardless of differences in geographic locations or climatic conditions, and then the bamboo dies. The lack of environmental impact on the time of flowering indicates the presence of some sort of "alarm clock" in each cell of the plant which signals the diversion of all energy to flower production and the cessation of vegetative growth. This mechanism, as well as the evolutionary cause behind it, is still largely a mystery.

 

One hypothesis to explain the evolution of this semelparous mass flowering is the predator satiation hypothesis which argues that by fruiting at the same time, a population increases the survival rate of their seeds by flooding the area with fruit, so, even if predators eat their fill, seeds will still be left over. By having a flowering cycle longer than the lifespan of the rodent predators, bamboos can regulate animal populations by causing starvation during the period between flowering events. Thus the death of the adult clone is due to resource exhaustion, as it would be more effective for parent plants to devote all resources to creating a large seed crop than to hold back energy for their own regeneration.

 

Another, the fire cycle hypothesis, argues that periodic flowering followed by death of the adult plants has evolved as a mechanism to create disturbance in the habitat, thus providing the seedlings with a gap in which to grow. This argues that the dead culms create a large fuel load, and also a large target for lightning strikes, increasing the likelihood of wildfire. Because bamboos can be aggressive as early successional plants, the seedlings would be able to outstrip other plants and take over the space left by their parents.

 

However, both have been disputed for different reasons. The predator satiation hypothesis does not explain why the flowering cycle is 10 times longer than the lifespan of the local rodents, something not predicted. The bamboo fire cycle hypothesis is considered by a few scientists to be unreasonable; they argue[20] that fires only result from humans and there is no natural fire in India. This notion is considered wrong based on distribution of lightning strike data during the dry season throughout India. However, another argument against this is the lack of precedent for any living organism to harness something as unpredictable as lightning strikes to increase its chance of survival as part of natural evolutionary progress.

 

More recently, a mathematical explanation for the extreme length of the flowering cycles has been offered, involving both the stabilizing selection implied by the predator satiation hypothesis and others, and the fact that plants that flower at longer intervals tend to release more seeds. The hypothesis claims that bamboo flowering intervals grew by integer multiplication. A mutant bamboo plant flowering at a non-integer multiple of its population's flowering interval would release its seeds alone, and would not enjoy the benefits of collective flowering (such as protection from predators). On the other hand, a mutant bamboo plant flowering at an integer multiple of its population's flowering interval would release its seeds only during collective flowering events, and would release more seeds than the average plant in the population. It could therefore take over the population, establishing a flowering interval that is an integer multiple of the previous flowering interval. The hypothesis predicts that observed bamboo flowering intervals should factorize into small prime numbers.

 

The mass fruiting also has direct economic and ecological consequences, however. The huge increase in available fruit in the forests often causes a boom in rodent populations, leading to increases in disease and famine in nearby human populations. For example, devastating consequences occur when the Melocanna bambusoides population flowers and fruits once every 30–35 years around the Bay of Bengal. The death of the bamboo plants following their fruiting means the local people lose their building material, and the large increase in bamboo fruit leads to a rapid increase in rodent populations. As the number of rodents increases, they consume all available food, including grain fields and stored food, sometimes leading to famine. These rats can also carry dangerous diseases, such as typhus, typhoid, and bubonic plague, which can reach epidemic proportions as the rodents increase in number. The relationship between rat populations and bamboo flowering was examined in a 2009 Nova documentary "Rat Attack".

 

In any case, flowering produces masses of seeds, typically suspended from the ends of the branches. These seeds will give rise to a new generation of plants that may be identical in appearance to those that preceded the flowering, or they may produce new cultivars with different characteristics, such as the presence or absence of striping or other changes in coloration of the culms.

 

Several bamboo species are never known to set seed even when sporadically flowering has been reported. Bambusa vulgaris, Bambusa balcooa and Dendrocalamus stocksii are common examples of such bamboo.

 

AS ANIMAL DIET

Soft bamboo shoots, stems, and leaves are the major food source of the giant panda of China, the red panda of Nepal and the bamboo lemurs of Madagascar. Rats will eat the fruits as described above. Mountain gorillas of Africa also feed on bamboo, and have been documented consuming bamboo sap which was fermented and alcoholic; chimpanzees and elephants of the region also eat the stalks.

 

The larvae of the bamboo borer (the moth Omphisa fuscidentalis) of Laos, Myanmar, Thailand and Yunnan Province, China, feeds off the pulp of live bamboo. In turn, these caterpillars are considered a local delicacy.

 

CULTIVATION

COMMERCIAL TIMBER

Timber is harvested from both cultivated and wild stands, and some of the larger bamboos, particularly species in the genus Phyllostachys, are known as "timber bamboos".

 

HARVESTING

Bamboo used for construction purposes must be harvested when the culms reach their greatest strength and when sugar levels in the sap are at their lowest, as high sugar content increases the ease and rate of pest infestation.

 

Harvesting of bamboo is typically undertaken according to the following cycles:

 

1) Life cycle of the culm: As each individual culm goes through a 5– to 7-year life cycle, culms are ideally allowed to reach this level of maturity prior to full capacity harvesting. The clearing out or thinning of culms, particularly older decaying culms, helps to ensure adequate light and resources for new growth. Well-maintained clumps may have a productivity three to four times that of an unharvested wild clump. Consistent with the life cycle described above, bamboo is harvested from two to three years through to five to seven years, depending on the species.

 

2) Annual cycle: As all growth of new bamboo occurs during the wet season, disturbing the clump during this phase will potentially damage the upcoming crop. Also during this high rainfall period, sap levels are at their highest, and then diminish towards the dry season. Picking immediately prior to the wet/growth season may also damage new shoots. Hence, harvesting is best a few months prior to the start of the wet season.

 

3) Daily cycle: During the height of the day, photosynthesis is at its peak, producing the highest levels of sugar in sap, making this the least ideal time of day to harvest. Many traditional practitioners believe the best time to harvest is at dawn or dusk on a waning moon.

 

LEACHING

Leaching is the removal of sap after harvest. In many areas of the world, the sap levels in harvested bamboo are reduced either through leaching or postharvest photosynthesis.

 

EXEMPLES OF THIS PRACTICE INCLUDE:

Cut bamboo is raised clear of the ground and leaned against the rest of the clump for one to two weeks until leaves turn yellow to allow full consumption of sugars by the plant.

A similar method is undertaken, but with the base of the culm standing in fresh water, either in a large drum or stream to leach out sap.

Cut culms are immersed in a running stream and weighted down for three to four weeks.

Water is pumped through the freshly cut culms, forcing out the sap (this method is often used in conjunction with the injection of some form of treatment).

 

In the process of water leaching, the bamboo is dried slowly and evenly in the shade to avoid cracking in the outer skin of the bamboo, thereby reducing opportunities for pest infestation.

 

Durability of bamboo in construction is directly related to how well it is handled from the moment of planting through harvesting, transportation, storage, design, construction and maintenance. Bamboo harvested at the correct time of year and then exposed to ground contact or rain, will break down just as quickly as incorrectly harvested material.

 

ORNAMENTAL BAMBOOS

The two general patterns for the growth of bamboo are "clumping" (sympodial) and "running" (monopodial). Clumping bamboo species tend to spread slowly, as the growth pattern of the rhizomes is to simply expand the root mass gradually, similar to ornamental grasses. "Running" bamboos, on the other hand, need to be controlled during cultivation because of their potential for aggressive behavior. They spread mainly through their roots and/or rhizomes, which can spread widely underground and send up new culms to break through the surface. Running bamboo species are highly variable in their tendency to spread; this is related to both the species and the soil and climate conditions. Some can send out runners of several metres a year, while others can stay in the same general area for long periods. If neglected, over time they can cause problems by moving into adjacent areas.

 

Bamboos seldom and unpredictably flower, and the frequency of flowering varies greatly from species to species. Once flowering takes place, a plant will decline and often die entirely. Although there are always a few species of bamboo in flower at any given time, collectors desiring to grow specific bamboo typically obtain their plants as divisions of already-growing plants, rather than waiting for seeds to be produced.

 

Regular observations will indicate major growth directions and locations. Once the rhizomes are cut, they are typically removed; however, rhizomes take a number of months to mature, and an immature, severed rhizome will usually cease growing if left in-ground. If any bamboo shoots come up outside of the bamboo area afterwards, their presence indicates the precise location of the removed rhizome. The fibrous roots that radiate from the rhizomes do not produce more bamboo.

 

Bamboo growth is also controlled by surrounding the plant or grove with a physical barrier. Typically, concrete and specially rolled HDPE plastic are the materials used to create the barrier, which is placed in a 60– to 90-cm-deep ditch around the planting, and angled out at the top to direct the rhizomes to the surface. (This is only possible if the barrier is installed in a straight line.) If the containment area is small, this method can be detrimental to ornamental bamboo, as the bamboo within can become rootbound and start to display the signs of any unhealthy containerized plant. In addition, rhizomes can escape over the top, or beneath the barrier if it is not deep enough. Strong rhizomes and tools can penetrate plastic barriers, so care must be taken. In small areas, regular maintenance may be the best method for controlling the running bamboos. Barriers and edging are unnecessary for clump-forming bamboos, although these may eventually need to have portions removed if they become too large.

 

The ornamental plant sold in containers and marketed as "lucky bamboo" is actually an entirely unrelated plant, Dracaena sanderiana. It is a resilient member of the lily family that grows in the dark, tropical rainforests of Southeast Asia and Africa. Lucky bamboo has long been associated with the Eastern practice of feng shui and images of the plant widely available on the Web are often used to depict bamboo. On a similar note, Japanese knotweed is also sometimes mistaken for a bamboo, but it grows wild and is considered an invasive species. Phyllostachys species of bamboo are also considered invasive and illegal to sell or propagate in some areas of the US.

 

USES

CULINARY

Although the shoots (new culms that come out of the ground) of bamboo contain a toxin taxiphyllin (a cyanogenic glycoside) that produces cyanide in the gut, proper processing renders them edible. They are used in numerous Asian dishes and broths, and are available in supermarkets in various sliced forms, in both fresh and canned versions. The golden bamboo lemur ingests many times the quantity of the taxiphyllin-containing bamboo that would kill a human.

 

The bamboo shoot in its fermented state forms an important ingredient in cuisines across the Himalayas. In Assam, India, for example, it is called khorisa. In Nepal, a delicacy popular across ethnic boundaries consists of bamboo shoots fermented with turmeric and oil, and cooked with potatoes into a dish that usually accompanies rice (alu tama (आलु तामा) in Nepali).

 

In Indonesia, they are sliced thin and then boiled with santan (thick coconut milk) and spices to make a dish called gulai rebung. Other recipes using bamboo shoots are sayur lodeh (mixed vegetables in coconut milk) and lun pia (sometimes written lumpia: fried wrapped bamboo shoots with vegetables). The shoots of some species contain toxins that need to be leached or boiled out before they can be eaten safely.

 

Pickled bamboo, used as a condiment, may also be made from the pith of the young shoots.

 

The sap of young stalks tapped during the rainy season may be fermented to make ulanzi (a sweet wine) or simply made into a soft drink. Bamboo leaves are also used as wrappers for steamed dumplings which usually contains glutinous rice and other ingredients.

 

Pickled bamboo shoots (Nepali:तामा tama) are cooked with black-eyed beans as a delicacy food in Nepal. Many Nepalese restaurant around the world serve this dish as aloo bodi tama. Fresh bamboo shoots are sliced and pickled with mustard seeds and turmeric and kept in glass jar in direct sunlight for the best taste. It is used alongside many dried beans in cooking during winter months. Baby shoots (Nepali: tusa) of a very different variety of bamboo (Nepali: निगालो Nigalo) native to Nepal is cooked as a curry in Hilly regions.

 

In Sambalpur, India, the tender shoots are grated into juliennes and fermented to prepare kardi. The name is derived from the Sanskrit word for bamboo shoot, karira. This fermented bamboo shoot is used in various culinary preparations, notably amil, a sour vegetable soup. It is also made into pancakes using rice flour as a binding agent. The shoots that have turned a little fibrous are fermented, dried, and ground to sand-sized particles to prepare a garnish known as hendua. It is also cooked with tender pumpkin leaves to make sag green leaves.

 

In Konkani cuisine, the tender shoots (kirlu) are grated and cooked with crushed jackfruit seeds to prepare 'kirla sukke'.

 

The empty hollow in the stalks of larger bamboo is often used to cook food in many Asian cultures. Soups are boiled and rice is cooked in the hollows of fresh stalks of bamboo directly over a flame. Similarly, steamed tea is sometimes rammed into bamboo hollows to produce compressed forms of Pu-erh tea. Cooking food in bamboo is said to give the food a subtle but distinctive taste.

 

In addition, bamboo is frequently used for cooking utensils within many cultures, and is used in the manufacture of chopsticks. In modern times, some see bamboo tools as an ecofriendly alternative to other manufactured utensils.

 

MEDICINE

Bamboo is used in Chinese medicine for treating infections and healing. In northern Indian state of Assam, the fermented bamboo paste known as khorisa is known locally as a folk remedy for the treatment of impotence, infertility, and menstrual pains.

 

CONSTRUCTION

Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.

 

In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.

 

Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong. In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support. In Japanese architecture, bamboo is used primarily as a supplemental and/or decorative element in buildings such as fencing, fountains, grates and gutters, largely due to the ready abundance of quality timber.

 

Various structural shapes may be made by training the bamboo to assume them as it grows. Squared sections of bamboo are created by compressing the growing stalk within a square form. Arches may similarly be created by forcing the bamboo's growth into the desired form, costing much less than it would to obtain the same shape with regular wood timber. More traditional forming methods, such as the application of heat and pressure, may also be used to curve or flatten the cut stalks.

 

Bamboo can be cut and laminated into sheets and planks. This process involves cutting stalks into thin strips, planing them flat, and boiling and drying the strips; they are then glued, pressed and finished. Long used in China and Japan, entrepreneurs started developing and selling laminated bamboo flooring in the West during the mid-1990s; products made from bamboo laminate, including flooring, cabinetry, furniture and even decorations, are currently surging in popularity, transitioning from the boutique market to mainstream providers such as Home Depot. The bamboo goods industry (which also includes small goods, fabric, etc.) is expected to be worth $25 billion by 2012. The quality of bamboo laminate varies among manufacturers and varies according to the maturity of the plant from which it was harvested (six years being considered the optimum); the sturdiest products fulfill their claims of being up to three times harder than oak hardwood while others may be softer than standard hardwood.

 

Bamboo intended for use in construction should be treated to resist insects and rot. The most common solution for this purpose is a mixture of borax and boric acid. Another process involves boiling cut bamboo to remove the starches that attract insects.

 

Bamboo has been used as reinforcement for concrete in those areas where it is plentiful, though dispute exists over its effectiveness in the various studies done on the subject. Bamboo does have the necessary strength to fulfil this function, but untreated bamboo will swell with water absorbed from the concrete, causing it to crack. Several procedures must be followed to overcome this shortcoming.

 

Several institutes, businesses, and universities are researching the use of bamboo as an ecological construction material. In the United States and France, it is possible to get houses made entirely of bamboo,[citation needed] which are earthquake- and cyclone-resistant and internationally certified. In Bali, Indonesia, an international K-12 school, the Green School, is constructed entirely of bamboo, for its beauty and advantages as a sustainable resource. There are three ISO standards for bamboo as a construction material.

 

In parts of India, bamboo is used for drying clothes indoors, both as a rod high up near the ceiling to hang clothes on, and as a stick wielded with acquired expert skill to hoist, spread, and to take down the clothes when dry. It is also commonly used to make ladders, which apart from their normal function, are also used for carrying bodies in funerals. In Maharashtra, the bamboo groves and forests are called Veluvana, the name velu for bamboo is most likely from Sanskrit, while vana means forest.

 

Furthermore, bamboo is also used to create flagpoles for saffron-coloured, Hindu religious flags, which can be seen fluttering across India, especially in Bihar and Uttar Pradesh, as well as in Guyana and Suriname in South America.

 

Bamboo was used for the structural members of the India pavilion at Expo 2010 in Shanghai. The pavilion is the world’s largest bamboo dome, about 34 m in diameter, with bamboo beams/members overlaid with a ferro-concrete slab, waterproofing, copper plate, solar PV panels, a small windmill, and live plants. A total of 30 km of bamboo was used. The dome is supported on 18-m-long steel piles and a series of steel ring beams. The bamboo was treated with borax and boric acid as a fire retardant and insecticide and bent in the required shape. The bamboo sections were joined with reinforcement bars and concrete mortar to achieve the necessary lengths.

 

TEXTILES

Since the fibers of bamboo are very short (less than 3 mm), they are not usually transformed into yarn by a natural process. The usual process by which textiles labeled as being made of bamboo are produced uses only rayon made from the fibers with heavy employment of chemicals. To accomplish this, the fibers are broken down with chemicals and extruded through mechanical spinnerets; the chemicals include lye, carbon disulfide and strong acids. Retailers have sold both end products as "bamboo fabric" to cash in on bamboo's current ecofriendly cachet; however, the Canadian Competition Bureau and the US Federal Trade Commission, as of mid-2009, are cracking down on the practice of labeling bamboo rayon as natural bamboo fabric. Under the guidelines of both agencies, these products must be labeled as rayon with the optional qualifier "from bamboo".

 

AS A WRITING SURFACE

Bamboo was in widespread use in early China as a medium for written documents. The earliest surviving examples of such documents, written in ink on string-bound bundles of bamboo strips (or "slips"), date from the fifth century BC during the Warring States period. However, references in earlier texts surviving on other media make it clear that some precursor of these Warring States period bamboo slips was in use as early as the late Shang period (from about 1250 BC).

 

Bamboo or wooden strips were the standard writing material during the Han dynasty, and excavated examples have been found in abundance. Subsequently, paper began to displace bamboo and wooden strips from mainstream uses, and by the fourth century AD, bamboo slips had been largely abandoned as a medium for writing in China. Several paper industries are surviving on bamboo forests. Ballarpur (Chandrapur, Maharstra) paper mills use bamboo for paper production.

 

Bamboo fiber has been used to make paper in China since early times. A high-quality, handmade paper is still produced in small quantities. Coarse bamboo paper is still used to make spirit money in many Chinese communities.

 

Bamboo pulps are mainly produced in China, Myanmar, Thailand and India, and are used in printing and writing papers. The most common bamboo species used for paper are Dendrocalamus asper and Bamboo bluemanea. It is also possible to make dissolving pulp from bamboo. The average fiber length is similar to hardwoods, but the properties of bamboo pulp are closer to softwood pulps due to it having a very broad fiber length distribution. With the help of molecular tools, it is now possible to distinguish the superior fiber-yielding species/varieties even at juvenile stages of their growth, which can help in unadulterated merchandise production.[

 

WEAPONS

Bamboo has often been used to construct weapons and is still incorporated in several Asian martial arts.

 

A bamboo staff, sometimes with one end sharpened, is used in the Tamil martial art of silambam, a word derived from a term meaning "hill bamboo".

Staves used in the Indian martial art of gatka are commonly made from bamboo, a material favoured for its light weight.

A bamboo sword called a shinai is used in the Japanese martial art of kendo.

Bamboo is used for crafting the bows, called yumi, and arrows used in the Japanese martial art kyudo.

Bamboo is sometimes used to craft the limbs of the longbow and recurve bow used in traditional archery, and to make superior weapons for bowhunting and target archery.

The first gunpowder-based weapons, such as the fire lance, were made of bamboo.

Bamboo was apparently used in East and South Asia as a means of torture.

 

OTHER USES

Bamboo has traditionally been used to make a wide range of everyday utensils, particularly in Japan, where archaeological excavations have uncovered bamboo baskets dating to the Late Jomon period (2000–1000 BC).

 

Bamboo has a long history of use in Asian furniture. Chinese bamboo furniture is a distinct style based on a millennia-long tradition.

 

Several manufacturers offer bamboo bicycles, surfboards, snowboards, and skateboards.

 

Due to its flexibility, bamboo is also used to make fishing rods. The split cane rod is especially prized for fly fishing. Bamboo has been traditionally used in Malaysia as a firecracker called a meriam buluh or bamboo cannon. Four-foot-long sections of bamboo are cut, and a mixture of water and calcium carbide are introduced. The resulting acetylene gas is ignited with a stick, producing a loud bang. Bamboo can be used in water desalination. A bamboo filter is used to remove the salt from seawater.

 

Food is cooked in East Timor in bamboo in fire. This is called Tukir.

 

Many minority groups in remote areas that have water access in Asia use bamboo that is 3–5 years old to make rafts. They use 8 to 12 poles, 6–7 metres long, laid together side by side to a width of about 1 metre. Once the poles are lined up together, they cut a hole crosswise through the poles at each end and use a small bamboo pole pushed through that hole like a screw to hold all the long bamboo poles together. Floating houses use whole bamboo stalks tied together in a big bunch to support the house floating in the water. Bamboo is also used to make eating utensils such as chop sticks, trays, and tea scoops.

 

The Song Dynasty (960–1279 AD) Chinese scientist and polymath Shen Kuo (1031–1095) used the evidence of underground petrified bamboo found in the dry northern climate of Yan'an, Shanbei region, Shaanxi province to support his geological theory of gradual climate change.

 

SYMBOLISM AND CULTURE

Bamboo's long life makes it a Chinese symbol of uprightness, while in India it is a symbol of friendship. The rarity of its blossoming has led to the flowers' being regarded as a sign of impending famine. This may be due to rats feeding upon the profusion of flowers, then multiplying and destroying a large part of the local food supply. The most recent flowering began in May 2006 (see Mautam). Bamboo is said to bloom in this manner only about every 50 years (see 28–60 year examples in FAO: 'gregarious' species table).

 

In Chinese culture, the bamboo, plum blossom, orchid, and chrysanthemum (often known as méi lán zhú jú 梅兰竹菊) are collectively referred to as the Four Gentlemen. These four plants also represent the four seasons and, in Confucian ideology, four aspects of the junzi ("prince" or "noble one"). The pine (sōng 松), the bamboo (zhú 竹), and the plum blossom (méi 梅) are also admired for their perseverance under harsh conditions, and are together known as the "Three Friends of Winter" (岁寒三友 suìhán sānyǒu) in Chinese culture. The "Three Friends of Winter" is traditionally used as a system of ranking in Japan, for example in sushi sets or accommodations at a traditional ryokan. Pine (matsu 松) is of the first rank, bamboo (také 竹) is of second rank, and plum (ume 梅) is of the third.

 

The Bozo ethnic group of West Africa take their name from the Bambara phrase bo-so, which means "bamboo house". Bamboo is also the national plant of St. Lucia.

 

BAMBOO, NOBLE AND USEFUL

Bamboo, one of the "Four Gentlemen" (bamboo, orchid, plum blossom and chrysanthemum), plays such an important role in traditional Chinese culture that it is even regarded as a behavior model of the gentleman. As bamboo has features such as uprightness, tenacity, and hollow heart, people endow bamboo with integrity, elegance, and plainness, though it is not physically strong. Countless poems praising bamboo written by ancient Chinese poets are actually metaphorically about people who exhibited these characteristics. According to laws, an ancient poet, Bai Juyi (772–846), thought that to be a gentleman, a man does not need to be physically strong, but he must be mentally strong, upright, and perseverant. Just as a bamboo is hollow-hearted, he should open his heart to accept anything of benefit and never have arrogance or prejudice. Bamboo is not only a symbol of a gentleman, but also plays an important role in Buddhism, which was introduced into China in the first century. As canons of Buddhism forbids cruelty to animals, flesh and egg were not allowed in the diet. The tender bamboo shoot (sǔn筍 in Chinese) thus became a nutritious alternative. Preparation methods developed over thousands of years have come to incorporated into Asian cuisines, especially for monks. A Buddhist monk, Zan Ning, wrote a manual of the bamboo shoot called "Sǔn Pǔ筍譜" offering descriptions and recipes for many kinds of bamboo shoots. Bamboo shoot has always been a traditional dish on the Chinese dinner table, especially in southern China. In ancient times, those who could afford a big house with a yard would plant bamboo in their garden.

 

In Japan, a bamboo forest sometimes surrounds a Shinto shrine as part of a sacred barrier against evil. Many Buddhist temples also have bamboo groves.

 

Bamboo plays an important part of the culture of Vietnam. Bamboo symbolizes the spirit of Vovinam (a Vietnamese martial arts): cương nhu phối triển (coordination between hard and soft (martial arts)). Bamboo also symbolizes the Vietnamese hometown and Vietnamese soul: the gentlemanlike, straightforwardness, hard working, optimism, unity, and adaptability. A Vietnamese proverb says, "When the bamboo is old, the bamboo sprouts appear", the meaning being Vietnam will never be annihilated; if the previous generation dies, the children take their place. Therefore, the Vietnam nation and Vietnamese value will be maintained and developed eternally. Traditional Vietnamese villages are surrounded by thick bamboo hedges (lũy tre).

 

IN MYTHOLOGY

Several Asian cultures, including that of the Andaman Islands, believe humanity emerged from a bamboo stem.

 

In Philippine mythology, one of the more famous creation accounts tells of the first man, Malakás ("Strong"), and the first woman, Maganda ("Beautiful"), each emerged from one half of a split bamboo stem on an island formed after the battle between Sky and Ocean. In Malaysia, a similar story includes a man who dreams of a beautiful woman while sleeping under a bamboo plant; he wakes up and breaks the bamboo stem, discovering the woman inside. The Japanese folktale "Tale of the Bamboo Cutter" (Taketori Monogatari) tells of a princess from the Moon emerging from a shining bamboo section. Hawaiian bamboo ('ohe) is a kinolau or body form of the Polynesian creator god Kāne.

 

A bamboo cane is also the weapon of Vietnamese legendary hero, Saint Giong, who had grown up immediately and magically since the age of three because of his wish to liberate his land from Ân invaders. An ancient Vietnamese legend (The Hundred-knot Bamboo Tree) tells of a poor, young farmer who fell in love with his landlord's beautiful daughter. The farmer asked the landlord for his daughter's hand in marriage, but the proud landlord would not allow her to be bound in marriage to a poor farmer. The landlord decided to foil the marriage with an impossible deal; the farmer must bring him a "bamboo tree of 100 nodes". But Gautama Buddha (Bụt) appeared to the farmer and told him that such a tree could be made from 100 nodes from several different trees. Bụt gave to him four magic words to attach the many nodes of bamboo: Khắc nhập, khắc xuất, which means "joined together immediately, fell apart immediately". The triumphant farmer returned to the landlord and demanded his daughter. Curious to see such a long bamboo, the landlord was magically joined to the bamboo when he touched it, as the young farmer said the first two magic words. The story ends with the happy marriage of the farmer and the landlord's daughter after the landlord agreed to the marriage and asked to be separated from the bamboo.

 

In a Chinese legend, the Emperor Yao gave two of his daughters to the future Emperor Shun as a test for his potential to rule. Shun passed the test of being able to run his household with the two emperor's daughters as wives, and thus Yao made Shun his successor, bypassing his unworthy son. Later, Shun drowned in the Xiang River. The tears his two bereaved wives let fall upon the bamboos growing there explains the origin of spotted bamboo. The two women later became goddesses.

In December 1961, the Hamburg-Südamerikanische Dampfschifffahrts-Gesellschaft Eggert & Amsinck launched the brand-new general cargo ship cap San Diego. The vessel was built by Deutsche Werft AG right in Hamburg-Finkenwerder.

 

During its first voyage in 1962. Cap San Diego sailed to Montreal, Baltimore, New York, Recife, Rio de Janeiro, Buenos Aires, Santos, Antwerp, Rotterdam and Bremen before returning to Hamburg, each such round trip takes about 60 days. However, just a few years after its launch, marine bulk cargo transportation, or more specifically, break-bulk cargo transportation, was already rapid moving to the more efficient containerization, and general cargo ships like Cap San Diego were becoming obsolete rapidly.

 

By 1986, the ship was reaching the end of her useful life and scheduled to be broken up and scrapped. At that point, The Free and Hanseatic City of Hamburg decided to buy the Hamburg-built ship and restored her to a floating museum that we see today.

 

JACKSONVILLE, Fla. (Aug. 5, 2019) - Cargo activity through Jacksonville’s seaport positively impacts tens of thousands of jobs and supports nearly $31.1 billion in annual economic output for the region and state, according to a newly released study. The study, citing double-digit growth in the port’s total economic impact over the last five years, was conducted by Martin Associates, a widely recognized maritime research firm.

 

In the Jacksonville area, the study concludes that 26,282 people are employed in port-dependent positions—direct, indirect and induced jobs relying on the port. This figure represents a nearly 8 percent increase over a previous study conducted in 2013. The port’s total economic value of $31.1 billion has also increased 15 percent during this time. In addition, the study finds that 138,500 jobs across the state of Florida are related to cargo moving through Jacksonville’s port.

 

Port-dependent jobs pay an average annual salary of $70,570, well above the state of Florida average salary for all occupations of $46,010.

 

JAXPORT’s Asian container trade is a primary driver of the port’s containerized cargo growth, up 89 percent since 2013. JAXPORT offers competitive transit times to destinations in Asia including China, Japan, South Korea, Vietnam, Thailand and more.

 

The port achieved significant Asian volume increases following the 2017 decision by the JAXPORT Board of Directors to begin construction on the project to deepen the Jacksonville shipping channel to 47 ft. The report finds that this steady volume growth underscores the importance of harbor deepening, which will allow JAXPORT to accommodate more cargo aboard the increasingly larger ships calling Jacksonville. The project is ahead of schedule and expected to be complete in 2023, based on continued funding from all partners.

 

A previous study conducted by Martin Associates in 2014 projected that JAXPORT’s Asian container business would generate 5,675 direct, indirect and induced jobs by the year 2020. The new study finds the actual number of these jobs in 2018 has already reached 5,538, a difference of about 2 percent from the forecast for 2020.

 

The report also finds that every 1,000 vehicles that move through the port supports 1.6 direct local jobs. JAXPORT is the nation’s second largest vehicle-handling port, moving more than 665,000 units last year.

 

“The successes we are experiencing throughout all of our lines of business have a direct and lasting impact on our region and state,” said JAXPORT CEO Eric Green. “The more we continue to invest in this port and grow our reputation as a global gateway into the Southeast U.S., the more jobs we create for our neighbors and the more revenue we put back into our area’s economy.”

 

The study concludes that in 2018, cargo activity at Jacksonville’s seaport generated $2.6 billion in business revenue, including $767.4 million in wages, $634.6 million in business purchases and $247.1 million in state and local taxes.

The Port of Oakland loads and discharges more than 99 percent of the containerized goods moving through Northern California, the nation's fourth largest metropolitan area. Oakland's cargo volume makes it the fourth busiest containerport in the United States, and ranks San Francisco Bay among the three principal Pacific Coast gateways for U.S. containerized cargoes, along with San Pedro Bay in southern California and Puget Sound in the Pacific Northwest. About 58.9 percent of Oakland's trade is with Asia. Europe accounts for 10.3 percent, Australia/New Zealand and South Pacific Islands about 4.7 percent and other foreign economies about 8.8 percent. About 17.3 percent of Oakland's trade is domestic (Hawaii and Guam) and military cargo. California's three major containerports carry approximately 50 percent on the nation's total container cargo volume.

Having slugged up the grades from Sodwalls to Rydal, 8105 continues to blast uphill with an extra 8934 containerized ore train from Blayney to Port Kembla. Compared to the typical trio of locomotives on the full sized train, it was refreshing to hear a single EMD locomotive working hard instead.

After being delayed on the way up due to trackwork and a possesion CFCLAs CM3303 and CM3301 waste no time as they charge 1877 containerized log through Marrangaroo.

Following our visit to the 1896 three-masted barque Rickmer Rickers, we fast-forwarded 65 years to the 1961 general cargo ship Cap San Diego, another ship museum at the port of Hamburg.

 

Even though I'm not an engineer, I've always been fascinated by transportation and logistics, and seeing a cargo ship's engine room, cargo holds, bridge and living quarters was interesting.

In December 1961, the Hamburg-Südamerikanische Dampfschifffahrts-Gesellschaft Eggert & Amsinck launched the brand-new general cargo ship cap San Diego. The vessel was built by Deutsche Werft AG right in Hamburg-Finkenwerder.

 

During its first voyage om 1962. Cap San Diego sailed to Montreal, Baltimore, New York, Recife, Rio de Janeiro, Buenos Aires, Santos, Antwerp, Rotterdam and Bremen before returning to Hamburg, each such round trip takes about 60 days. However, just a few years after its launch, marine bulk cargo transportation, or more specifically, break-bulk cargo transportation, was already rapid moving to the more efficient containerization, and general cargo ships like Cap San Diego were becoming obsolete rapidly.

 

By 1986, the ship was reaching the end of her useful life and scheduled to be broken up and scrapped. At that point, The Free and Hanseatic City of Hamburg decided to buy the Hamburg-built ship and restored her to a floating museum that we see today.

The BNSF Railway (AAR reporting marks BNSF) headquartered in Fort Worth, Texas, is one of the four remaining transcontinental railroads and one of the largest railroad networks in North America. Only the Union Pacific Railroad is larger in size. With globalization, the transcontinental railroads are a key component in the containerization of trade from the Pacific Rim. The BNSF Railway moves more intermodal freight traffic than any other rail system in the world.

 

It was formed December 31, 1996, as the Burlington Northern and Santa Fe Railway when the Atchison, Topeka and Santa Fe Railway was merged into the Burlington Northern Railroad. In 1999 the BNSF Railway and the Canadian National Railway announced their intention to merge and form a new corporation entitled the North American Railways to be headquartered in Montreal, Canada. The United States' Surface Transportation Board (STB) placed a 15-month moratorium on all rail mergers, which ended this merger. On January 24, 2005, the railroad's name was officially changed to BNSF Railway.[1]

 

The BNSF Railway is a wholly owned subsidiary of the Burlington Northern Santa Fe Corporation, the holding company formed by the September 22, 1995 merger of Burlington Northern, Incorporated and the Santa Fe Pacific Corporation. According to corporate press releases, the BNSF Railway is among the top transporters of intermodal freight in North America. It moves more grain than any other American railroad. It also hauls enough coal to generate roughly 10% of the electricity produced in the United States. The company's northern route completes the high-speed link from the western to eastern United States.

 

This was the route of the Great Northern Railway's Silk Extras in the 1920s. They had priority over all other trains, stopping only for refueling and crew changes. These trains transported silk to the east from ships arriving in the Port of Seattle from Japan.

Wish I had kept better notes. This train had a lot of mail on it but I don't know anymore if it was a solid train of mail cars or had passenger cars in it. What I do know is the front has RPO's on it, and I shot the rear on the bridge also, and that was more RPO cars. These days, of course, all the RPO business is gone but solid mail trains do still run in a few places - I know the Swiss run containerized mail trains using special side door containers and the French actually have some TGV high speed trains painted all yellow assigned to handling only mail.

The DQ class locomotives are a class of mainline diesel-electric locomotives in New Zealand and Tasmania, Australia.

Originally Queensland Rail 1460 and 1502 class, they were purchased by New Zealand Rail Limited in 1995 to be rebuilt, as a cheaper alternative to buying new locomotives.

They arrived in New Zealand as the QR classes 1460 and 1502, most of which were then rebuilt by Hutt Workshops into the DQ class. During rebuilding their cabs were modified with the addition of two large windows, short hood lowered, a computerised control system installed, upgrading of the engines, fitting of dynamic brakes and the addition of noise insulation. The QR locomotives that were not rebuilt received only minimal alteration before being used as trailing locomotives. All were painted in Tranz Rail's corporate livery of light blue and yellow before being put into service.

They are not favoured however by their crews due to complaints of rough riding and excessive cab noise.

They are also considered unreliable by senior management (DQ units in Tasmania have a high rate of generator failure), so they are now mainly used for short-haul runs, such as on the final leg of coal trains from the West Coast between Christchurch and the port of Lyttelton and on the Ohai Branch Line to and from Invercargill, hauling containerized coal trains. They are also used as bankers to help trains up the steep grade out of Picton.

As of 2011, only three DQ locomotives are in service (all in the South Island); the remaining QR units that were not rebuilt have been sold after lengthy periods of storage at the Hutt Workshops. DQ 6347 suffered damage when toppled onto its side after derailing on entry to the Picton yard in late 2009, after which it was sent to Hutt Workshops for repair. It remained out-of service with little work undertaken on it for months but was eventually repaired and returned to service in October 2011. DQ 6376 is currently out of service after it was derailed when the freight train it was part of struck a slip south of Kaikoura in June 2011. In both cases the DQ was operating as the trailing locomotive (in multiple with another) and unoccupied at the time of derailment.

In 1998 Tranz Rail began to export locomotives to Tasmania for use on TasRail, then part-owned by Tranz Rail. In total, twelve DQ were exported, along with three unrebuilt QR class. On 2 September 1998 the first two locomotives in the planned replacement of Tasmania’s mainly English Electric locomotive fleet arrived in Tasmania from New Zealand. The first GM-powered locomotives in Tasmania were originally two ex-Queensland Railways 1502 class purchased by Tranz Rail for use in New Zealand in 1996. All DQ class locomotives were rebuilt and modified at Tranz Rail’s Hutt workshops at Wellington, before being shipped to Tasmania.

 

Latest report on this locomotive is that it is operated by a cement company to work at a site near the Nacala Corridor in Mozambique as RRL22-02.

PortMiami, formally the Dante B. Fascell Port of Miami, is a major seaport located in Biscayne Bay in Miami, Florida. It is the largest passenger port in the world, and one of the largest cargo ports in the United States. It is connected to Downtown Miami by Port Boulevard—a causeway over the Intracoastal Waterway—and to the neighboring Watson Island via the PortMiami Tunnel. The port is located on Dodge Island, which is the combination of three historic islands (Dodge, Lummus and Sam's Islands) that have since been combined into one. It is named in honor of 19 term Florida Congressman Dante Fascell.

 

As of 2011, PortMiami accounts for 176,000 jobs and has an annual economic impact in Miami of $18 billion.

 

In the early 1900s, Government Cut was dredged along with a new channel to what now is known as Bicentennial Park in downtown Miami[4]. This new access to the mainland created the Main Channel which greatly improved the shipping access to the new port. From these original dredging spoils which were disposed on the south side of the new Main Channel, new islands were inadvertently created which later became Dodge, Lummus and Sam's Island along with several other smaller islands.

 

As the port grew through the years as a result of the improved shipping access and growth of the South Florida community, it also needed additional lands to expand its operation. As such, on April 5, 1960 the Dade County Board of Commissioners approved Resolution No. 4830, "Joint Resolution Providing for Construction of Modern Seaport Facilities at Dodge Island Site" which on April 6, 1960 the City of Miami approved the same as City Resolution No. 31837 to construct the new Port of Miami. Soon thereafter, work began on constructing the new port on Dodge Island by expanding the island and joining it other islands in the general vicinity. Then upon construction of the new seawalls, transit shed 'A', the administration building and a new vehicle and railroad bridge, the operations were transferred from the mainland port to the new port on Dodge Island. Thereafter through the years, additional fill material from dredging enlarged the islands of Lummus and Sam's along with the filling of the North, South and NOAO slips, creating the new port which is built on a completely man made island.

 

PortMiami boasts the title "cruise capital of the world", and is the busiest cruise/passenger port in the world. It accommodates the operations of such major cruise lines as Carnival, Royal Caribbean and Norwegian Cruise Line. It was home of the largest cruise ships in the world until 2009, when Port Everglades became home to Oasis of the Seas and its sister ship, Allure of the Seas. Currently the following ships are based in Miami: Carnival Vista, Carnival Sensation, Carnival Glory, Carnival Victory, Carnival Splendor, Enchantment of the Seas, Empress of the Seas, Navigator of the Seas, Norwegian Getaway, Norwegian Escape, Norwegian Sky, Disney Magic.

 

In 2018, PortMiami became homeport for five more modern megaliners: Mariner of the Seas, Allure of the Seas, Symphony of the Seas, Carnival Horizon, and Norwegian Bliss.

 

As the "Cargo Gateway of the Americas", the port primarily handles containerized cargo with small amounts of breakbulk, vehicles and industrial equipment. It is the largest container port in the state of Florida and ninth in the United States. As a world-class port, PortMiami is among an elite group of ports in the world which cater to both cruise ships and containerized cargo.

 

PortMiami is an important contributor to the local south Florida and state economies. Over four million cruise passengers pass through the Port, 7.4 million tons of cargo and over 1 million twenty-foot equivalent units (TEU) (FY 2004/2005) of intermodal container traffic move through the seaport per year. This combination of cruise and cargo activities supports approximately 176,000 jobs, and has an economic impact in Miami-Dade County of over $17 billion, $14 billion of which is generated by its cargo operations.

 

The port currently operates eight passenger terminals, six gantry cranes wharves, seven Ro-Ro (Roll-on-Roll-off) docks, four refrigerated yards for containers, break bulk cargo warehouses and nine gantry container handling cranes. In addition, the port tenants operate the cruise and cargo terminals which includes their cargo handling and support equipment.

 

To retain the port's competitive rank as a world-class port, in 1997 the port undertook a redevelopment program of over $250 million which is well underway to accommodate the changing demands of cruise vessel operators, passengers, shippers and carriers. To further resolve accessibility, the PortMiami Tunnel was constructed in 2010 and completed in 2014, providing direct vehicle access from the port to the interstate highway system via State Road 836, thereby bypassing congestion in downtown Miami.

 

As part of the massive PortMiami redevelopment program, new ultramodern cruise terminals, roadways and parking garages have been constructed. Additionally, a new gantry crane dock and container storage yards have been constructed along with the electrification of the gantry crane docks to include the conversion of several cranes has been completed. In addition, the Port acquired two state-of-the-art super post-panamax gantry cranes which are amongst the largest in the world; able to load and unload 22 container (8 foot wide each), or nearly 200 foot, wide mega container ships. This, along with the planned Deep Dredge Project, would make it possible for PortMiami to facilitate even the future largest containerships in the world, the Maersk Triple E Class. The new and restructured roadway system with new lighting, landscaping and signage greets visitors to the 'Cruise Capital of the World and Cargo Gateway of the Americas'. The roadways will change again with the completion of the PortMiami Tunnel. And to enhance cargo port accessibility, the newly constructed Security Gates opened at the end of 2006 to increase the processing rate for container trucks and help eliminate the daily traffic backups.

 

In March 2018, Norwegian Cruise Line Holdings unveiled details on the new NCL-dedicated terminal at PortMiami. The company intends to open it by fall 2019.

 

In July 2018, MSC Cruises announced its plans to build Terminal AAA for its upcoming World-class cruise ships.[

The Manned Orbiting Laboratory (MOL) was part of the United States Air Force (USAF) human spaceflight program in the 1960s. The project was developed from early USAF concepts of crewed space stations as reconnaissance satellites, and was a successor to the canceled Boeing X-20 Dyna-Soar military reconnaissance space plane. MOL evolved into a single-use laboratory, for which crews would be launched on 30-day missions, and return to Earth using a Gemini B spacecraft derived from NASA's Gemini spacecraft.

 

The MOL program was announced to the public on 10 December 1963 as an inhabited platform to demonstrate the utility of putting people in space for military missions; its reconnaissance satellite mission was a secret black project. Seventeen astronauts were selected for the program. The prime contractor for the spacecraft was McDonnell Aircraft; the laboratory was built by the Douglas Aircraft Company. The Gemini B was externally similar to NASA's Gemini spacecraft, although it underwent several modifications, including the addition of a circular hatch through the heat shield, which allowed passage between the spacecraft and the laboratory. Vandenberg Air Force Base Space Launch Complex 6 (SLC 6) was developed to permit launches into polar orbit.

 

As the 1960s progressed, the MOL competed with the Vietnam War for funds, and resultant budget cuts repeatedly caused postponement of the first operational flight. At the same time, automated systems rapidly improved, narrowing the benefits of a crewed space platform over an automated one. A single uncrewed test flight of the Gemini B spacecraft was conducted on 3 November 1966, but the MOL was canceled in June 1969 without any crewed missions being flown.

 

Seven of the astronauts selected for the MOL program transferred to NASA in August 1969 as NASA Astronaut Group 7, all of whom eventually flew in space on the Space Shuttle between 1981 and 1985. The Titan IIIM rocket developed for the MOL never flew, but its UA1207 solid rocket boosters were used on the Titan IV, and the Space Shuttle Solid Rocket Booster was based on materials, processes and designs developed for them. NASA spacesuits were derived from the MOL ones, MOL's waste management system flew in space on Skylab, and NASA Earth Science used other MOL equipment. SLC 6 was refurbished, but plans to have military Space Shuttle launches from there were abandoned in the wake of the January 1986 Space Shuttle Challenger disaster.

  

NASA's Gemini capsule was extensively redesigned for the MOL Manned Orbiting Laboratory program. The resulting Gemini B, although externally similar, was essentially a completely new spacecraft. Gemini B was not designed to fly separately, but rather was launched with the crew aboard attached to the manned orbiting laboratory. After reaching orbit, the crew would shut down the capsules systems and put them into hibernation. They would crawl through an 0.635 m diameter hatch in the heat shield, leading to a tunnel that accessed the MOL itself. After thirty days of operations, the crew would return to the Gemini B, separate from the MOL, and reenter the atmosphere. Gemini B had only 14 hours of free flight time for autonomous operations after separation from the MOL.

 

Several changes were made from the original NASA Gemini, including:

 

-Internal systems were containerized and designed for long term orbital storage

-The cockpit layout was completely redesigned and new instruments were developed

-The cant of the ejection seats were changed in order to make room for the hatch in the heat shield between the crew's shoulders

-Cabin atmosphere was changed to Helium-Oxygen in place of pure oxygen. At launch, the crew breathed pure oxygen in their suits while the cabin was filled with pure helium. During ascent, oxygen from the suits slowly brought the cabin atmosphere up to the helium-oxygen content of the station itself.

-In order to handle higher energy reentries from polar orbit, the heat shield was increased in diameter, so that it actually stuck out a bit from the base of the reentry vehicle.

- The OAMS maneuvering thrusters of the NASA Gemini were deleted; spacecraft orientation in orbit was handled by the forward RCS thrusters.

-The number of solid propellant retrofire motors was increased from four to six. These served double-duty: for deorbit of the Gemini B and as abort rockets for separation of the Gemini from the enormous Titan 3M in case of launch vehicle failure.

 

The prototype Gemini-B, which was launched on a suborbital trajectory, was the refurbished Gemini-2 capsule, making it the first reused spacecraft. It was launched with the MOL-Heatshield Qualification Test on a Titan-3C launch vehicle.
