Themed Gardens Hortulus in Dobrzyca were founded in 1992. Their implementation is still ongoing. Currently available to explore 28 different themed gardens. Total accumulated more than 6000 species and varieties of plants, including species of exotic and unique. Gardens are in an extremely hot climate zone 7b, where the winters are mild and there is much more rainfall than in other parts of the country. Gardens have been repeatedly awarded, including by the Polish Tourist Organisation.
Garden area is more than four hectares. The essence of these gardens is to show the plants in the garden compositions and their use in the various gardens (hence the lack of name tags). Visiting Gardens Hortulus, beyond the obvious contact with nature, provides an aesthetic experience and the spiritual. Therefore, also the gardens are divided by theme. They include classic as well as Japanese, French, Mediterranean, and those related to the environment: garden stone, rock and water. There are also gardens, utility, and herbal or vegetable.

they could go no further it was terribly sad they just had to walk and knew they were mad
but what could they do as nightime came near and the sound of the wind filled them with fear
thought they heard horses & riders come near but was only echoes of memories held dear
the mind plays tricks as they soon would discover as darkness fell they clung to each other
they were only young and were all alone Father had gone as their Mother moaned
we are lost without horses, food and water all is lost and our lives are now shorter
who will save us from this dreadful end please hurry or else its a tale with no end..............!!!
Thank You Bev!

First Aberdeen implement fare revisions from today which see fares for those paying on bus or paper passes increase whilst those who purchase m-tickets will see the price remain or reduce. The company is also pushing contactless payment as an alternative believing that contactless and m-tickets are the key to cutting boarding time and speeding up journeys.

From First website:
BUS CUSTOMERS URGED TO SWITCH TO MOBILE TICKETS FOR BEST VALUE FARES
First Aberdeen has announced that some of its fares will be changing from Sunday 5th August 2018, but tickets bought via the First Bus mTickets app will be frozen or reduced to their 2017 price; offering customers the best value fares. Click here to view full details.
The changes will impact most tickets purchased on-bus and through PayPoint, but the bus operator has worked hard to keep any rises to a minimum and is urging customers to switch to mobile ticketing, for the best value fares available. For example;
The FirstWeek ticket will cost £18 if purchased from the driver, but a reduced price of £15.50 is offered when purchased in advance through the mTickets app.
First Aberdeen is also reducing the price of some of its most popular multi-journey products such as the day, monthly or five single tickets package when purchased via the mTickets app.
The majority of student ticket prices have been frozen on the mTickets app to allow students to plan and budget for their travel during term time.
First Aberdeen reports that sales of tickets via cashless methods, including mTickets and contactless, have more than doubled over the last year, and the local bus operator is now encouraging more customers to switch from cash to cashless payment methods, to help speed up boarding times. It is confident that journey times will improve if the trend of more customers using its mTickets app continues, as research* by First Bus has highlighted that boarding times would be 75 per cent faster, if customers switched from cash to mTicket.
Graeme Macfarlan, Commercial Director at First Aberdeen, said: “We generally need to review our fares each year to ensure we meet the rising costs that we face as a business, but we have worked hard to keep any increases to a minimum with ticket prices last reviewed in April ‘17.
“Travel by First Aberdeen offers great value for money and we continue to offer a lower price for most tickets purchased via the First Bus mTickets app, in comparison to tickets bought from the driver, so that we can encourage people to switch and speed up their boarding time. The exciting new First Bus Unlimited ticket also allows customers to pay a monthly direct debit for unlimited bus travel across their chosen network via the mTickets app; making regular bus travel more convenient than ever before.
“Our Aberdeen operation has seen a significant rise in ‘smart’ payments in recent months, with over 70 per cent of our customers now using a ‘cashless’ method. We are working hard to encourage more customers to convert to using mTickets or contactless, as this will have a further impact on reducing boarding times and will help us in the battle to speed up people’s journeys.”

Virtual Reality implemented in the scale model in front of these ladies, by wearing that pair of goggles, they were able to interact both with the model, and the surrounding space, mapped to satisfy and entertain their curiosity. Pleasant surprise from a pavilion that, besides that, has much to envy to other national exhibitions.
During the depression, money was hard to come by, and most people had to barter (trade) what goods and services they might have to get food and survive. Building materials back then were commonly Wood products, as metals were expensive, and later used in WW-II.
This was a typical shed/building that was built and used in the 40's-50's to store farm tractors and implements to keep them out of the weather and provide a comfortable place to work and do repairs.
Many of these old building have been left to the elements and have or are falling down. This one is still in fairly good condition, and was found along side the highway ;-}}

The office building of the Emerson-Brantingham Manufacturing
This powerhouse of industry employed 5,000 from 1905, when the city’s population was 50,000, including elderly, women and children. The company manufactured carriage, wagons, plows, farm implements, and eventually evolved into J.I. Case Co.
The sprawling manufacturing facility encompassed a 24 building, 175-acre complex was the largest modern agricultural implement machinery facility in the world at the time.
A close neighboring company was lurking in the wings. J.I. Case out of Racine, Wisconsin watched closely as Emerson Brantingham fell further and further behind. Their particularly keen interest was in the plant and facilities and the 28 vital patents that Emerson Brantingham held.
Finally, in November 1928, the Emerson Brantingham Company fell to the hands of J. I. Case. For what it's worth, Emerson Brantingham was one of the last of over 800 implement companies to fall prey to the times.
J. I. Case continued to manufacture agricultural implements at its Rockford works until 1970 when they closed the aging manufacturing facility. Finding no buyers for the sprawling complex, Case donated the site and 1.4 million square feet of buildings to the City of Rockford for use as the City Yards. It was demolished between 2023 and 2024.

After the implementation of gas buses in Runcorn the promised batch of Darlington’s MAN Ecocity’s, which are for use on local Darlington services 2, 11 and 12, started to arrive in March 2013. Here one such of these, NK13CFE is seen here at the vehicles new home depot. With help from The Green Bus Fund Arriva are placing a number of low emission vehicles into use.
These buses for Darlington, totalling 11, are due to enter service later this month, allegedly around two days service can be gained from one of these green (in more ways than one) buses on a full tank of Compress Natural Gas (CNG).
John Greaves (Arriva North East's engineering director) says that these new buses are "all about building customer confidence again" after the problems that resulted from the closure of Bishop Auckland Depot, and Peterlee Depot, where he admits "service did deteriorate a little bit". Tony Griffiths from MAN UK says that the order for these and the 10 buses for Arriva in the North West, was "justification for all the hard work we, and the Gas Bus Alliance, have put in... it’s enormously gratifying to see customers realise the full potential of MAN EcoCity". After all this is the way forward.
A new filling station is to be built at Faverdale which can fuel the buses with high pressure CNG.
My verdict – for what it’s worth – a nice smooth ride, spacious cab, green idea, attractive livery. Nice to see more new buses in the area too.

I got side tracked when I saw this shot in my stash. I know it takes my kind of mind to dream up a title such as this. Sometimes companies leave themselves open for the likes of me. Best be careful with slogans. I was at McIntosh Ag Museum again for my windmill agriculture shot and saw this but the title for this image only came when I opened the file. I had to work to preserve the remaining logo. This machinery is for the ages, the Iron or Dark ages! I should be able to spot some rust on it. I really need to get really close in on this and do a texture detail of the rust. I have a lot of close up gear I seldom use. It had to be iron heavy in order to be able to "bite" into the soil. It looked like a single row plow. Single row implements took some time to finish working a field, one row at a time. Manual labor for sure. Ahh, wheat to damage human guts.
This June found a return to hot temperatures. Wundermaps reported 101 degrees while I was out there. Whew! The direct sun blazed across the scene. I decided that I had needed some shots at McIntosh and went out in the baking sun.
Highway #66 seemed overloaded with early summer travelers to the hills, hoping for heat relief in the Rockies. Only the cow trail of snow remains up on Mount Meeker.

Essay:
Earth's Transformation and the Random Implementation of Alien Technology
The Earth, once a vibrant planet teeming with diverse ecosystems, has undergone a drastic transformation. A severe environmental catastrophe has devastated the planet, leading to the evaporation of life-giving water into the vast expanse of space. The once-blue planet is now dominated by barren deserts, stretching across continents where oceans and forests once thrived. Humanity, on the brink of extinction, has been thrust into a desperate struggle for survival.
The catalyst for this environmental apocalypse was a combination of factors: uncontrolled industrial activity, rampant deforestation, and unchecked pollution. These human activities pushed Earth's climate system past a critical threshold, triggering a cascade of irreversible changes. The polar ice caps melted at unprecedented rates, causing sea levels to rise and then rapidly fall as water vapor escaped the atmosphere. Rainforests, which acted as the planet's lungs, were decimated, and the delicate balance of ecosystems collapsed. The result was a planet unrecognizable from its former self—a desolate wasteland where life struggled to find a foothold.
In this dire scenario, hope arrived in the form of alien technology—an unexpected boon that became humanity's lifeline. The origins of this technology remain shrouded in mystery. Some speculate it was discovered accidentally during deep-space explorations, while others believe it was gifted by a benevolent extraterrestrial civilization. Regardless of its origins, this advanced technology became the cornerstone of Earth's new survival strategy.
The alien technology enabled the creation of isolated oases in the vast desert expanses. These oases, shielded by energy fields and sustained by advanced atmospheric processors, mimic the lost ecosystems of old Earth. They generate and recycle water, maintain breathable air, and support agriculture, allowing small human communities to thrive. The technology also includes sophisticated climate control mechanisms that protect these fertile areas from the harsh desert environment.
The implementation of alien technology was a stroke of luck, a fortuitous discovery in humanity's darkest hour. Scientists and engineers, initially skeptical, soon realized the potential of these alien devices. Through trial and error, they managed to integrate this technology into the remnants of human civilization. This integration was not without its challenges—there were numerous failures and setbacks, but the resilience of the human spirit prevailed.
Life in these technologically sustained oases is a stark contrast to the desolation that surrounds them. Within the protective domes, greenery flourishes, and small bodies of water reflect the sky. Communities have adapted to this new way of living, embracing a lifestyle that is a blend of ancient survival techniques and futuristic technology. Education systems focus on maintaining and understanding the alien technology, ensuring that future generations can continue to benefit from it.
The concept of 'Planet B' has taken on a new meaning. Instead of seeking a new home among the stars, humanity has been forced to redefine its existence on Earth—'Planet B' is Earth reborn, a new chapter after 'Planet A' vanished beneath the waves of environmental disaster. The Earth of today is a testament to human ingenuity and the unforeseen assistance of alien technology. It is a world where the line between science fiction and reality has blurred, and where survival hinges on the harmonious integration of alien and human advancements.
In conclusion, the transformation of Earth and the serendipitous implementation of alien technology have given rise to a new way of life. This new existence is fragile and fraught with challenges, but it is also a beacon of hope. The 'Cradle of the Desert' represents the resilience of life and the enduring quest for survival in the face of insurmountable odds.
Poem:
In deserts wide where oceans slept,
Beneath a sky where sorrow wept,
Alien whispers, silent, deep,
Brought life anew from restless sleep.
Once blue and green, now dust and bone,
Our planet’s heart, a hollow tone,
Yet through the sands, technology,
Revived the hope for you and me.
In domes of light, we plant our dreams,
Where water flows in gentle streams,
Alien hands unseen, yet kind,
Breathe life back to a world confined.
From barren waste to fertile land,
A future forged by chance and hand,
Cradle of the Desert, bright,
Guides us through this endless night.
Haikus:
Alien whispers,
Oases bloom in deserts,
Hope in arid lands.
Earth’s rebirth at hand,
Technology’s gentle touch,
Life in barren sands.

The main environmental issues associated with the implementation of the 5G network come with the manufacturing of the many component parts of the 5G infrastructure. In addition, the proliferation of new devices that will use the 5G network that is tied to the acceleration of demand from consumers for new 5G-dependent devices will have serious environmental consequences. The 5G network will inevitably cause a large increase in energy usage among consumers, which is already one of the main contributors to climate change. Additionally, the manufacturing and maintenance of the new technologies associated with 5G creates waste and uses important resources that have detrimental consequences for the environment. 5G networks use technology that has harmful effects on birds, which in turn has cascading effects through entire ecosystems. And, while 5G developers are seeking to create a network that has fewer environmental impacts than past networks, there is still room for improvement and the consequences of 5G should be considered before it is widely rolled out. 5G stands for the fifth generation of wireless technology. It is the wave of wireless technology surpassing the 4G network that is used now. Previous generations brought the first cell phones (1G), text messaging (2G), online capabilities (3G), and faster speed (4G). The fifth generation aims to increase the speed of data movement, be more responsive, and allow for greater connectivity of devices simultaneously.[2] This means that 5G will allow for nearly instantaneous downloading of data that, with the current network, would take hours. For example, downloading a movie using 5G would take mere seconds. These new improvements will allow for self-driving cars, massive expansion of Internet of Things (IoT) device use, and acceleration of new technological advancements used in everyday activities by a much wider range of people. While 5G is not fully developed, it is expected to consist of at least five new technologies that allow it to perform much more complicated tasks at faster speeds. The new technologies 5G will use are hardware that works with much higher frequencies (millimeter wavelengths), small cells, massive MIMO (multiple input multiple output), beamforming, and full duplex.[3] Working together, these new technologies will expand the potential of many of the devices used today and devices being developed for the future. Millimeter waves are a higher frequency wavelength than the radio wavelength generally used in wireless transmission today.[4] The use of this portion of the spectrum corresponds to higher frequency and shorter wavelengths, in this case in the millimeter range (vs the lower radio frequencies where the wavelengths can be in the meters to hundreds of kilometers). Higher frequency waves allow for more devices to be connected to the same network at the same time, because there is more space available compared to the radio waves that are used today. The use of this portion of the spectrum has much longer wavelengths than of that anticipated for a portion of the 5G implementation. The waves in use now can measure up to tens of centimeters, while the new 5G waves would be no greater than ten millimeters.[5] The millimeter waves will create more transmission space for the ever-expanding number of people and devices crowding the current networks. The millimeter waves will create more space for devices to be used by consumers, which will increase energy usage, subsequently leading to increased global warming. Millimeter waves are very weak in their ability to connect two devices, which is why 5G needs something called “small cells” to give full, uninterrupted coverage. Small cells are essentially miniature cell towers that would be placed 250 meters apart throughout cities and other areas needing coverage.[6] The small cells are necessary as emissions [or signals] at this higher frequency/shorter wavelength have more difficulty passing through solid objects and are even easily intercepted by rain.[7] The small cells could be placed on anything from trees to street lights to the sides of businesses and homes to maximize connection and limit “dead zones” (areas where connections are lost). The next new piece of technology necessary for 5G is massive MIMO, which stands for multiple input multiple output. The MIMO describes the capacity of 5G’s base stations, because those base stations would be able to handle a much higher amount of data at any one moment of time. Currently, 4G base stations have around eight transmitters and four receivers which direct the flow of data between devices.[9] 5G will exceed this capacity with the use of massive MIMO that can handle 22 times more ports. Figure 1 shows how a massive MIMO tower would be able to direct a higher number of connections at once. However, massive MIMO causes signals to be crossed more easily. Crossed signals cause an interruption in the transmission of data from one device to the next due to a clashing of the wavelengths as they travel to their respective destinations. To overcome the cross signals problem, beamforming is needed. To maximize the efficiency of sending data another new technology called beamforming will be used in 5G. For data to be sent to the correct user, a way of directing the wavelengths without interference is necessary. This is done through a technique called beamforming. Beamforming directs where exactly data are being sent by using a variety of antennas to organize signals based on certain characteristics, such as the magnitude of the signal. By directly sending signals to where they need to go, beamforming decreases the chances that a signal is dropped due to the interference of a physical object.
One way that 5G will follow through on its promise of faster data transmission is through sending and receiving data simultaneously. The method that allows for simultaneous input and output of data is called full duplexing. While full duplex capabilities allow for faster transmission of data, there is an issue of signal interference, because of echoes. Full duplexing will cut transmission times in half, because it allows for a response to occur as soon as an input is delivered, eliminating the turnaround time that is seen in transmission today. Because these technologies are new and untested, it is hard to say how they will impact our environment. This raises another issue: there are impacts that can be anticipated and predicted, but there are also unanticipated impacts because much of the new technologies are untested. Nevertheless, it is possible to anticipate some of detrimental environmental consequences of the new technologies and the 5G network, because we know these technologies will increase exposure to harmful radiation, increase mining of rare minerals, increase waste, and increase energy usage. The main 5G environmental concerns have to do with two of the five new components: the millimeter waves and the small cells. The whole aim of the new 5G network is to allow for more devices to be used by the consumer at faster rates than ever before, because of this goal there will certainly be an increase in energy usage globally. Energy usage is one of the main contributors to climate change today and an increase in energy usage would cause climate change to increase drastically as well. 5G will operate on a higher frequency portion of the spectrum to open new space for more devices. The smaller size of the millimeter waves compared to radio frequency waves allows for more data to be shared more quickly and creates a wide bandwidth that can support much larger tasks.[15] While the idea of more space for devices to be used is great for consumers, this will lead to a spike in energy usage for two reasons – the technology itself is energy demanding and will increase demand for more electronic devices. The ability for more devices to be used on the same network creates more incentive for consumers to buy electronics and use them more often. This will have a harmful impact on the environment through increased energy use. Climate change has several underlying contributors; however, energy usage is gaining attention in its severity with regards to perpetuating climate change. Before 5G has even been released, about 2% of the world’s greenhouse gas emissions can be attributed to the ICT industry.[16] While 2% may not seem like a very large portion, it translates to around 860 million tons of greenhouse gas emissions.[17] Greenhouse gas emissions are the main contributors to natural disasters, such as flooding and drought, which are increasing severity and occurrence every year. Currently, roughly 85% of the energy used in the United States can be attributed to fossil fuel consumption.[18] The dwindling availability of fossil fuels and the environmental burden of releasing these fossil fuels into our atmosphere signal an immediate need to shift to other energy sources. Without a shift to other forms of energy production and the addition of technology allowed by the implementation of 5G, the strain on our environment will rise and the damage may never be repaired. With an increase in energy usage through technology and the implementation of 5G, it can be expected that the climate change issues faced today will only increase. The overall contribution of carbon dioxide emissions from the ICT industry has a huge impact on climate change and will continue to have even larger impacts without proper actions. In a European Union report, researchers estimated that in order to keep the increase in global temperature below 2° Celsius a decrease in carbon emissions of around 15-30% is necessary by 2020. Engineers claim that the small cells used to provide the 5G connection will be energy efficient and powered in a sustainable way; however the maintenance and production of these cells is more of an issue. Supporters of the 5G network advocate that the small cells will use solar or wind energy to stay sustainable and green.[20] These devices, labeled “fuel-cell energy servers” will work as clean energy-based generators for the small cells.[21] While implementing base stations that use sustainable energy to function would be a step in the right direction in environmental conservation, it is not the solution to the main issue caused by 5G, which is the impact that the massive amount of new devices in the hands of consumers will have on the amount of energy required to power these devices. The wasteful nature of manufacturing and maintenance of both individual devices and the devices used to deliver 5G connection could become a major contributor of climate change. The promise of 5G technology is to expand the number of devices functioning might be the most troubling aspect of the new technology. Cell phones, computers, and other everyday devices are manufactured in a way that puts stress on the environment. A report by the EPA estimated that in 2010, 25% of the world’s greenhouse gas emissions comes from electricity and heat production making it the largest single source of emissions.[22] The main gas emitted by this sector is carbon dioxide, due to the burning of natural gas, such as coal, to fuel electricity sources.[23] Carbon dioxide is one of the most common greenhouse gases seen in our atmosphere, it traps heat in earth’s atmosphere trying to escape into space, which causes the atmosphere to warm generating climate change. Increased consumption of devices is taking a toll on the environment. As consumers gain access to more technologies the cycle of consumption only expands. As new devices are developed, the older devices are thrown out even if they are still functional. Often, big companies will purposefully change their products in ways that make certain partner devices (such as chargers or earphones) unusable–creating demand for new products. Economic incentives mean that companies will continue these practices in spite of the environmental impacts. One of the main issues with the 5G network and the resulting increase in consumption of technological devices is that the production required for these devices is not sustainable. In the case of making new devices, whether they be new smart-phones or the small cells needed for 5G, the use of nonrenewable metals is required. It is extremely difficult to use metals for manufacturing sustainably, because metals are not a renewable resource. Metals used in the manufacturing of the smart devices frequently used today often cannot be recycled in the same way many household items can be recycled. Because these technologies cannot be recycled, they create tons of waste when they are created and tons of waste when they are thrown away. There are around six billion mobile devices in use today, with this number expected to increase drastically as the global population increases and new devices enter the market. One estimate of the life-time carbon emissions of a single device–not including related accessories and network connection–is that a device produces a total of 45kg of carbon dioxide at a medium level of usage over three years. This amount of emission is comparable to that of driving the average European car for 300km. But, the most environmentally taxing stage of a mobile device life cycle is during the production stage, where around 68% of total carbon emissions is produced, equating to 30kg of carbon dioxide. To put this into perspective, an iPhone X weighs approximately 0.174kg, so in order to produce the actual device, 172 iPhone X’s worth of carbon dioxide is also created. These emissions vary from person to person and between different devices, but it’s possible to estimate the impact one device has on the environment. 5G grants the capacity for more devices to be used, significantly increase the existing carbon footprint of smart devices today. Energy usage for the ever-growing number of devices on the market and in homes is another environmental threat that would be greatly increased by the new capabilities brought by the 5G network. Often, energy forecasts overlook the amount of energy that will be consumed by new technologies, which leads to a skewed understanding of the actual amount of energy expected to be used.[30] One example of this is with IoT devices.[31] IoT is one of the main aspects of 5G people in the technology field are most excited about. 5G will allow for a larger expansion of IoT into the everyday household.[32] While some IoT devices promise lower energy usage abilities, the 50 billion new IoT devices expected to be produced and used by consumers will surpass the energy used by today’s electronics.
The small cells required for the 5G network to properly function causes another issue of waste with the new network. Because of the weak nature of the millimeter waves used in the 5G technology, small cells will need to be placed around 250 meters apart to insure continuous connection. The main issue with these small cells is that the manufacturing and maintenance of these cells will create a lot of waste. The manufacturing of technology takes a large toll on the environment, due to the consumption of non-renewable resources to produce devices, and technology ending up in landfills. Implementing these small cells into large cities where they must be placed at such a high density will have a drastic impact on technology waste. Technology is constantly changing and improving, which is one of the huge reasons it has such high economic value. But, when a technological advancement in small cells happens, the current small cells would have to be replaced. The short lifespan of devices created today makes waste predictable and inevitable. In New York City, where there would have to be at least 3,135,200 small cells, the waste created in just one city when a new advancement in small cells is implemented would have overwhelming consequences on the environment. 5G is just one of many examples of how important it is to look at the consequences of new advancements before their implementation. While it is exciting to see new technology that promises to improve everyday life, the consequences of additional waste and energy usage must be considered to preserve a sustainable environment in the future. There is some evidence that the new devices and technologies associated with 5G will be harmful to delicate ecosystems. The main component of the 5G network that will affect the earth’s ecosystems is the millimeter waves. The millimeter waves that are being used in developing the 5G network have never been used at such scale before. This makes it especially difficult to know how they will impact the environment and certain ecosystems. However, studies have found that there are some harms caused by these new technologies. The millimeter waves, specifically, have been linked to many disturbances in the ecosystems of birds. In a study by the Centre for Environment and Vocational Studies of Punjab University, researchers observed that after exposure to radiation from a cell tower for just 5-30 minutes, the eggs of sparrows were disfigured.[34] The disfiguration of birds exposed for such a short amount of time to these frequencies is significant considering that the new 5G network will have a much higher density of base stations (small cells) throughout areas needing connection. The potential dangers of having so many small cells all over areas where birds live could cause whole populations of birds to have mutations that threaten their population’s survival. Additionally, a study done in Spain showed breeding, nesting, and roosting was negatively affected by microwave radiation emitted by a cell tower. Again, the issue of the increase in the amount of connection conductors in the form of small cells to provide connection with the 5G network is seen to be harmful to species that live around humans. Additionally, Warnke found that cellular devices had a detrimental impact on bees.[36] In this study, beehives exposed for just ten minutes to 900MHz waves fell victim to colony collapse disorder.Colony collapse disorder is when many of the bees living in the hive abandon the hive leaving the queen, the eggs, and a few worker bees. The worker bees exposed to this radiation also had worsened navigational skills, causing them to stop returning to their original hive after about ten days. Bees are an incredibly important part of the earth’s ecosystem. Around one-third of the food produced today is dependent on bees for pollination, making bees are a vital part of the agricultural system. Bees not only provide pollination for the plant-based food we eat, but they are also important to maintaining the food livestock eats. Without bees, a vast majority of the food eaten today would be lost or at the very least highly limited. Climate change has already caused a large decline in the world’s bee population. The impact that the cell towers have on birds and bees is important to understand, because all ecosystems of the earth are interconnected. If one component of an ecosystem is disrupted the whole system will be affected. The disturbances of birds with the cell towers of today would only increase, because with 5G a larger number of small cell radio-tower-like devices would be necessary to ensure high quality connection for users. Having a larger number of high concentrations of these millimeter waves in the form of small cells would cause a wider exposure to bees and birds, and possibly other species that are equally important to our environment.As innovation continues, it is important that big mobile companies around the world consider the impact 5G will have on the environment before pushing to have it widely implemented. The companies pushing for the expansion of 5G may stand to make short term economic gains. While the new network will undoubtedly benefit consumers greatly, looking at 5G’s long-term environmental impacts is also very important so that the risks are clearly understood and articulated. The technology needed to power the new 5G network will inevitably change how mobile devices are used as well as their capabilities. This technological advancement will also change the way technology and the environment interact. The change from using radio waves to using millimeter waves and the new use of small cells in 5G will allow more devices to be used and manufactured, more energy to be used, and have detrimental consequences for important ecosystems. While it is unrealistic to call for 5G to not become the new network norm, companies, governments, and consumers should be proactive and understand the impact that this new technology will have on the environment. 5G developers should carry out Environmental Impact Assessments that fully estimate the impact that the new technology will have on the environment before rushing to widely implement it. Environmental Impact Assessments are intended to assess the impact new technologies have on the environment, while also maximizing potential benefits to the environment. This process mitigates, prevents, and identifies environmental harm, which is imperative to ensuring that the environment is sustainable and sound in the future. Additionally, the method of Life Cycle Assessments (LCA) of devices would also be extremely beneficial for understanding the impact that 5G will inevitably have on the environment. An LCA can be used to assess the impact that devices have on carbon emissions throughout their life span, from the manufacturing of the device to the energy required to power the device and ultimately the waste created when the device is discarded into a landfill or other disposal system. By having full awareness of the impact new technology will have on the environment ways to combat the negative impacts can be developed and implemented effectively.

The train-tablet system is operated to implement a train-spacing system designed to prevent more than one train occupying a single line section between any two tablet-stations at one and the same time. When the line is not occupied ( "Line Closed" ) their operation may permit the admittance of a train from one or other end of the tablet section. This is accomplished by requiring the driver of each train to carry an appropriate tablet, a hard-wood disc familiarly know as the biscuit. The biscuits not in active use are naturally locked up within the tablet instruments. The Tablets are severely rationed, not more than one can be extracted from the relevant cupboard at any one time. Control of the cupboards is remote.
The unlocking of the instrument at the approach end of the section involves complementary action by the tablet porter at the terminal end, the one to which the given train is travelling, the withdrawal of the tablet leaves locked the instrument from which it is taken. It cannot be unlocked again for the obtaining of a successive tablet until the operator at the far station inserts into his own machine the tablet that has been carried along the entire section. It is however possible for a tablet to be replaced into either machine.
en.wikipedia.org/wiki/Aswan_Dam
The Aswan Dam, or more specifically since the 1960s, the Aswan High Dam, is the world's largest embankment dam, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. Its significance largely eclipsed the previous Aswan Low Dam initially completed in 1902 downstream. Based on the success of the Low Dam, then at its maximum utilization, construction of the High Dam became a key objective of the government following the Egyptian Revolution of 1952; with its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the economy and culture of Egypt.
Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during late summer had continued to pass largely unimpeded down the valley from its East African drainage basin. These floods brought high water with natural nutrients and minerals that annually enriched the fertile soil along its floodplain and delta; this predictability had made the Nile valley ideal for farming since ancient times. However, this natural flooding varied, since high-water years could destroy the whole crop, while low-water years could create widespread drought and consequently famine. Both these events had continued to occur periodically. As Egypt's population grew and technology increased, both a desire and the ability developed to completely control the flooding, and thus both protect and support farmland and its economically important cotton crop. With the greatly increased reservoir storage provided by the High Aswan Dam, the floods could be controlled and the water could be stored for later release over multiple years.
The Aswan Dam was designed by the Moscow-based Hydroproject Institute.
The earliest recorded attempt to build a dam near Aswan was in the 11th century, when the Arab polymath and engineer Ibn al-Haytham (known as Alhazen in the West) was summoned to Egypt by the Fatimid Caliph, Al-Hakim bi-Amr Allah, to regulate the flooding of the Nile, a task requiring an early attempt at an Aswan Dam. His field work convinced him of the impracticality of this scheme.
The British began construction of the first dam across the Nile in 1898. Construction lasted until 1902 and the dam was opened on 10 December 1902. The project was designed by Sir William Willcocks and involved several eminent engineers, including Sir Benjamin Baker and Sir John Aird, whose firm, John Aird & Co., was the main contractor.
In 1952, the Greek-Egyptian engineer Adrian Daninos began to develop the plan of the new Aswan Dam. Although the Low Dam was almost overtopped in 1946, the government of King Farouk showed no interest in Daninos's plans. Instead the Nile Valley Plan by the British hydrologist Harold Edwin Hurst was favored, which proposed to store water in Sudan and Ethiopia, where evaporation is much lower. The Egyptian position changed completely after the overthrow of the monarchy, led by the Free Officers Movement including Gamal Abdel Nasser. The Free Officers were convinced that the Nile Waters had to be stored in Egypt for political reasons, and within two months, the plan of Daninos was accepted. Initially, both the United States and the USSR were interested in helping development of the dam. Complications ensued due to their rivalry during the Cold War, as well as growing intra-Arab tensions.
In 1955, Nasser was claiming to be the leader of Arab nationalism, in opposition to the traditional monarchies, especially the Hashemite Kingdom of Iraq following its signing of the 1955 Baghdad Pact. At that time the U.S. feared that communism would spread to the Middle East, and it saw Nasser as a natural leader of an anticommunist procapitalist Arab League. America and the United Kingdom offered to help finance construction of the High Dam, with a loan of $270 million, in return for Nasser's leadership in resolving the Arab-Israeli conflict. While opposed to communism, capitalism, and imperialism, Nasser identified as a tactical neutralist, and sought to work with both the U.S. and the USSR for Egyptian and Arab benefit.[8] After the UN criticized a raid by Israel against Egyptian forces in Gaza in 1955, Nasser realized that he could not portray himself as the leader of pan-Arab nationalism if he could not defend his country militarily against Israel. In addition to his development plans, he looked to quickly modernize his military, and he turned first to the U.S. for aid.
American Secretary of State John Foster Dulles and President Dwight Eisenhower told Nasser that the U.S. would supply him with weapons only if they were used for defensive purposes and if he accepted American military personnel for supervision and training. Nasser did not accept these conditions, and consulted the USSR for support.
Although Dulles believed that Nasser was only bluffing and that the USSR would not aid Nasser, he was wrong: the USSR promised Nasser a quantity of arms in exchange for a deferred payment of Egyptian grain and cotton. On 27 September 1955, Nasser announced an arms deal, with Czechoslovakia acting as a middleman for the Soviet support. Instead of attacking Nasser for turning to the Soviets, Dulles sought to improve relations with him. In December 1955, the US and the UK pledged $56 and $14 million, respectively, toward construction of the High Aswan Dam.
Though the Czech arms deal created an incentive for the US to invest at Aswan, the UK cited the deal as a reason for repealing its promise of dam funds. Dulles was angered more by Nasser's diplomatic recognition of China, which was in direct conflict with Dulles's policy of containment of communism.
Several other factors contributed to the US deciding to withdraw its offer of funding for the dam. Dulles believed that the USSR would not fulfil its commitment of military aid. He was also irritated by Nasser's neutrality and attempts to play both sides of the Cold War. At the time, other Western allies in the Middle East, including Turkey and Iraq, were resentful that Egypt, a persistently neutral country, was being offered so much aid.
In June 1956, the Soviets offered Nasser $1.12 billion at 2% interest for the construction of the dam. On 19 July the U.S. State Department announced that American financial assistance for the High Dam was "not feasible in present circumstances."
On 26 July 1956, with wide Egyptian acclaim, Nasser announced the nationalization of the Suez Canal that included fair compensation for the former owners. Nasser planned on the revenues generated by the canal to help fund construction of the High Dam. When the Suez War broke out, the United Kingdom, France, and Israel seized the canal and the Sinai. But pressure from the U.S. and the USSR at the United Nations and elsewhere forced them to withdraw.
In 1958, the USSR proceeded to provide support for the High Dam project.
In the 1950s, archaeologists began raising concerns that several major historical sites, including the famous temple of Abu Simbel were about to be submerged by waters collected behind the dam. A rescue operation began in 1960 under UNESCO
Despite its size, the Aswan project has not materially hurt the Egyptian balance of payments. The three Soviet credits covered virtually all of the project's foreign exchange requirements, including the cost of technical services, imported power generating and transmission equipment and some imported equipment for land reclamation. Egypt was not seriously burdened by payments on the credits, most of which were extended for 12 years with interest at the very low rate of 2-1/2%. Repayments to the USSR constituted only a small net drain during the first half of the 1960s, and increased export earnings derived from crops grown on newly reclaimed land have largely offset the modest debt service payments in recent years. During 1965–70, these export earnings amounted to an estimated $126 million, compared with debt service payments of $113 million.

The Soviets also provided technicians and heavy machinery. The enormous rock and clay dam was designed by the Soviet Hydroproject Institute along with some Egyptian engineers. 25,000 Egyptian engineers and workers contributed to the construction of the dams.
Originally designed by West German and French engineers in the early 1950s and slated for financing with Western credits, the Aswan High Dam became the USSR's largest and most famous foreign aid project after the United States, the United Kingdom, and the International Bank for Reconstruction and Development (IBRD) withdrew their support in 1956. The first Soviet loan of $100 million to cover construction of coffer dams for diversion of the Nile was extended in 1958. An additional $225 million was extended in 1960 to complete the dam and construct power-generating facilities, and subsequently about $100 million was made available for land reclamation. These credits of some $425 million covered only the foreign exchange costs of the project, including salaries of Soviet engineers who supervised the project and were responsible for the installation and testing of Soviet equipment. Actual construction, which began in 1960, was done by Egyptian companies on contract to the High Dam Authority, and all domestic costs were borne by the Egyptians. Egyptian participation in the venture has raised the construction industry's capacity and reputation significantly.
On the Egyptian side, the project was led by Osman Ahmed Osman's Arab Contractors. The relatively young Osman underbid his only competitor by one-half.
1960: Start of construction on 9 January
1964: First dam construction stage completed, reservoir started filling
1970: The High Dam, as-Sad al-'Aali, completed on 21 July[18]
1976: Reservoir reached capacity.
Specifications
The Aswan High Dam is 3,830 metres (12,570 ft) long, 980 m (3,220 ft) wide at the base, 40 m (130 ft) wide at the crest and 111 m (364 ft)[ tall. It contains 43,000,000 cubic metres (56,000,000 cu yd) of material. At maximum, 11,000 cubic metres per second (390,000 cu ft/s) of water can pass through the dam. There are further emergency spillways for an extra 5,000 cubic metres per second (180,000 cu ft/s), and the Toshka Canal links the reservoir to the Toshka Depression. The reservoir, named Lake Nasser, is 500 km (310 mi) long[20] and 35 km (22 mi) at its widest, with a surface area of 5,250 square kilometres (2,030 sq mi). It holds 132 cubic kilometres (1.73×1011 cu yd) of water.
Due to the absence of appreciable rainfall, Egypt's agriculture depends entirely on irrigation. With irrigation, two crops per year can be produced, except for sugar cane which has a growing period of almost one year.
The high dam at Aswan releases, on average, 55 cubic kilometres (45,000,000 acre⋅ft) water per year, of which some 46 cubic kilometres (37,000,000 acre⋅ft) are diverted into the irrigation canals.
In the Nile valley and delta, almost 336,000 square kilometres (130,000 sq mi) benefit from these waters producing on average 1.8 crops per year. The annual crop consumptive use of water is about 38 cubic kilometres (31,000,000 acre⋅ft). Hence, the overall irrigation efficiency is 38/46 = 0.826 or 83%. This is a relatively high irrigation efficiency. The field irrigation efficiencies are much less, but the losses are reused downstream. This continuous reuse accounts for the high overall efficiency.
The following table shows the distribution of irrigation water over the branch canals taking off from the one main irrigation canal, the Mansuriya Canal near Giza.

The salt concentration of the water in the Aswan reservoir is about 0.25 kilograms per cubic metre (0.42 lb/cu yd), a very low salinity level. At an annual inflow of 55 cubic kilometres (45,000,000 acre⋅ft), the annual salt influx reaches 14 million tons. The average salt concentration of the drainage water evacuated into the sea and the coastal lakes is 2.7 kilograms per cubic metre (4.6 lb/cu yd). At an annual discharge of 10 cubic kilometres (2.4 cu mi) (not counting the 2 kilograms per cubic metre [3.4 lb/cu yd] of salt intrusion from the sea and the lakes, see figure "Water balances"), the annual salt export reaches 27 million ton. In 1995, the output of salt was higher than the influx, and Egypt's agricultural lands were desalinizing. Part of this could be due to the large number of subsurface drainage projects executed in the last decades to control the water table and soil salinity.
Drainage through subsurface drains and drainage channels is essential to prevent a deterioration of crop yields from waterlogging and soil salinization caused by irrigation. By 2003, more than 20,000 square kilometres (7,700 sq mi) have been equipped with a subsurface drainage system and approximately 7.2 square kilometres (2.8 sq mi) of water is drained annually from areas with these systems. The total investment cost in agricultural drainage over 27 years from 1973 to 2002 was about $3.1 billion covering the cost of design, construction, maintenance, research and training. During this period 11 large-scale projects were implemented with financial support from World Bank and other donors.
Effects
The High Dam has resulted in protection from floods and droughts, an increase in agricultural production and employment, electricity production, and improved navigation that also benefits tourism. Conversely, the dam flooded a large area, causing the relocation of over 100,000 people. Many archaeological sites were submerged while others were relocated. The dam is blamed for coastline erosion, soil salinity, and health problems.
The assessment of the costs and benefits of the dam remains controversial decades after its completion. According to one estimate, the annual economic benefit of the High Dam immediately after its completion was LE 255 million, $587 million using the exchange rate in 1970 of $2.30 per LE 1): LE 140 million from agricultural production, LE 100 million from hydroelectric generation, LE 10 million from flood protection, and LE 5 million from improved navigation. At the time of its construction, total cost, including unspecified "subsidiary projects" and the extension of electric power lines, amounted to LE 450 million. Not taking into account the negative environmental and social effects of the dam, its costs are thus estimated to have been recovered within only two years. One observer notes: "The impacts of the Aswan High Dam have been overwhelmingly positive. Although the Dam has contributed to some environmental problems, these have proved to be significantly less severe than was generally expected, or currently believed by many people." Another observer disagreed and he recommended that the dam should be torn down. Tearing it down would cost only a fraction of the funds required for "continually combating the dam's consequential damage" and 500,000 hectares (1,900 sq mi) of fertile land could be reclaimed from the layers of mud on the bed of the drained reservoir. Samuel C. Florman wrote about the dam: "As a structure it is a success. But in its effect on the ecology of the Nile Basin – most of which could have been predicted – it is a failure".
Periodic floods and droughts have affected Egypt since ancient times. The dam mitigated the effects of floods, such as those in 1964, 1973, and 1988. Navigation along the river has been improved, both upstream and downstream of the dam. Sailing along the Nile is a favorite tourism activity, which is mainly done during the winter when the natural flow of the Nile would have been too low to allow navigation of cruise ships.[clarification needed] A new fishing industry has been created around Lake Nasser, though it is struggling due to its distance from any significant markets. The annual production was about 35 000 tons in the mid-1990s. Factories for the fishing industry and packaging have been set up near the Lake.
According to a 1971 CIA declassified report, Although the High Dam has not created ecological problems as serious as some observers have charged, its construction has brought economic losses as well as gains. These losses derive largely from the settling in dam's lake of the rich silt traditionally borne by the Nile. To date (1971), the main impact has been on the fishing industry. Egypt's Mediterranean catch, which once averaged 35,000-40,000 tons annually, has shrunk to 20,000 tons or less, largely because the loss of plankton nourished by the silt has eliminated the sardine population in Egyptian waters. Fishing in high dam's lake may in time at least partly offset the loss of saltwater fish, but only the most optimistic estimates place the eventual catch as high as 15,000-20,000 tons. Lack of continuing silt deposits at the mouth of the river also has contributed to a serious erosion problem. Commercial fertilizer requirements and salination and drainage difficulties, already large in perennially irrigated areas of Lower and Middle Egypt, will be somewhat increased in Upper Egypt by the change to perennial irrigation.
The dams also protected Egypt from the droughts in 1972–73 and 1983–87 that devastated East and West Africa. The High Dam allowed Egypt to reclaim about 2.0 million feddan (840,000 hectares) in the Nile Delta and along the Nile Valley, increasing the country's irrigated area by a third. The increase was brought about both by irrigating what used to be desert and by bringing under cultivation of 385,000 hectares (950,000 acres) that were previously used as flood retention basins. About half a million families were settled on these new lands. In particular the area under rice and sugar cane cultivation increased. In addition, about 1 million feddan (420,000 hectares), mostly in Upper Egypt, were converted from flood irrigation with only one crop per year to perennial irrigation allowing two or more crops per year. On other previously irrigated land, yields increased because water could be made available at critical low-flow periods. For example, wheat yields in Egypt tripled between 1952 and 1991 and better availability of water contributed to this increase. Most of the 32 km3 of freshwater, or almost 40 percent of the average flow of the Nile that were previously lost to the sea every year could be put to beneficial use. While about 10 km3 of the water saved is lost due to evaporation in Lake Nasser, the amount of water available for irrigation still increased by 22 km3. Other estimates put evaporation from Lake Nasser at between 10 and 16 cubic km per year.
Electricity production
The dam powers twelve generators each rated at 175 megawatts (235,000 hp), with a total of 2.1 gigawatts (2,800,000 hp). Power generation began in 1967. When the High Dam first reached peak output it produced around half of Egypt's production of electric power (about 15 percent by 1998), and it gave most Egyptian villages the use of electricity for the first time. The High Dam has also improved the efficiency and the extension of the Old Aswan Hydropower stations by regulating upstream flows.
All High Dam power facilities were completed ahead of schedule. 12 turbines were installed and tested, giving the plant an installed capacity of 2,100 megawatts (MW), or more than twice the national total in 1960. With this capacity, the Aswan plant can produce 10 billion kWh of energy yearly. Two 500-kilovolt trunk lines to Cairo have been completed, and initial transmission problems, stemming mainly from poor insulators, were solved. Also, the damage inflicted on a main transformer station in 1968 by Israeli commandos has been repaired, and the Aswan plant is fully integrated with the power network in Lower Egypt. By 1971 estimation, Power output at Aswan, won't reach much more than half of the plant's theoretical capacity, because of limited water supplies and the differing seasonal water-use patterns for irrigation and power production. Agricultural demand for water in the summer far exceeds the amount needed to meet the comparatively low summer demand for electric power. Heavy summer irrigation use, however, will leave insufficient water under Egyptian control to permit hydroelectric power production at full capacity in the winter. Technical studies indicate that a maximum annual output of 5 billion kWh appears to be all that can be sustained due to fluctuations in Nile flows.
Resettlement and compensations
In Sudan, 50,000 to 70,000 Sudanese Nubians were moved from the old town of Wadi Halfa and its surrounding villages. Some were moved to a newly created settlement on the shore of Lake Nasser called New Wadi Halfa, and some were resettled approximately 700 kilometres (430 mi) south to the semi-arid Butana plain near the town of Khashm el-Girba up the Atbara River. The climate there had a regular rainy season as opposed to their previous desert habitat in which virtually no rain fell. The government developed an irrigation project, called the New Halfa Agricultural Development Scheme to grow cotton, grains, sugar cane and other crops. The Nubians were resettled in twenty five planned villages that included schools, medical facilities, and other services, including piped water and some electrification.
In Egypt, the majority of the 50,000 Nubians were moved three to ten kilometers from the Nile near Edna and Kom Ombo, 45 kilometers (28 mi) downstream from Aswan in what was called "New Nubia". Housing and facilities were built for 47 village units whose relationship to each other approximated that in Old Nubia. Irrigated land was provided to grow mainly sugar cane.
In 2019–20, Egypt started to compensate the Nubians who lost their homes following the dam impoundment.
Archaeological sites
Twenty-two monuments and architectural complexes that were threatened by flooding from Lake Nasser, including the Abu Simbel temples, were preserved by moving them to the shores of the lake under the UNESCO Nubia Campaign. Also moved were Philae, Kalabsha and Amada.
These monuments were granted to countries that helped with the works:
The Debod temple to Madrid
The Temple of Dendur to the Metropolitan Museum of Art of New York
The Temple of Taffeh to the Rijksmuseum van Oudheden of Leiden
The Temple of Ellesyia to the Museo Egizio of Turin
These items were removed to the garden area of the Sudan National Museum of Khartoum:
The temple of Ramses II at Aksha
The temple of Hatshepsut at Buhen
The temple of Khnum at Kumma
The tomb of the Nubian prince Djehuti-hotep at Debeira
The temples of Dedwen and Sesostris III at Semna
The granite columns from the Faras Cathedral
A part of the paintings of the Faras Cathedral; the other part is in the National Museum of Warsaw.
The Temple of Ptah at Gerf Hussein had its free-standing section reconstructed at New Kalabsha, alongside the Temple of Kalabsha, Beit el-Wali, and the Kiosk of Qertassi.
The remaining archaeological sites, including the Buhen fort and the cemetery of Fadrus have been flooded by Lake Nasser.
Loss of sediments
Before the construction of the High Dam, the Nile deposited sediments of various particle size – consisting of fine sand, silt and clay – on fields in Upper Egypt through its annual flood, contributing to soil fertility. However, the nutrient value of the sediment has often been overestimated. 88 percent of the sediment was carried to the sea before the construction of the High Dam. The nutrient value added to the land by the sediment was only 6,000 tons of potash, 7,000 tons of phosphorus pentoxide and 17,000 tons of nitrogen. These amounts are insignificant compared to what is needed to reach the yields achieved today in Egypt's irrigation. Also, the annual spread of sediment due to the Nile floods occurred along the banks of the Nile. Areas far from the river which never received the Nile floods before are now being irrigated.
A more serious issue of trapping of sediment by the dam is that it has increased coastline erosion surrounding the Nile Delta. The coastline erodes an estimated 125–175 m (410–574 ft) per year.
Waterlogging and increase in soil salinity
Before the construction of the High Dam, groundwater levels in the Nile Valley fluctuated 8–9 m (26–30 ft) per year with the water level of the Nile. During summer when evaporation was highest, the groundwater level was too deep to allow salts dissolved in the water to be pulled to the surface through capillary action. With the disappearance of the annual flood and heavy year-round irrigation, groundwater levels remained high with little fluctuation leading to waterlogging. Soil salinity also increased because the distance between the surface and the groundwater table was small enough (1–2 m depending on soil conditions and temperature) to allow water to be pulled up by evaporation so that the relatively small concentrations of salt in the groundwater accumulated on the soil surface over the years. Since most of the farmland did not have proper subsurface drainage to lower the groundwater table, salinization gradually affected crop yields.[31] Drainage through sub-surface drains and drainage channels is essential to prevent a deterioration of crop yields from soil salinization and waterlogging. By 2003, more than 2 million hectares have been equipped with a subsurface drainage system at a cost from 1973 to 2002 of about $3.1 billion.
Health
Contrary to many predictions made prior to the Aswan High Dam construction and publications that followed, that the prevalence of schistosomiasis (bilharzia) would increase, it did not. This assumption did not take into account the extent of perennial irrigation that was already present throughout Egypt decades before the high dam closure. By the 1950s only a small proportion of Upper Egypt had not been converted from basin (low transmission) to perennial (high transmission) irrigation. Expansion of perennial irrigation systems in Egypt did not depend on the high dam. In fact, within 15 years of the high dam closure there was solid evidence that bilharzia was declining in Upper Egypt. S. haematobium has since disappeared altogether. Suggested reasons for this include improvements in irrigation practice. In the Nile Delta, schistosomiasis had been highly endemic, with prevalence in the villages 50% or higher for almost a century before. This was a consequence of the conversion of the Delta to perennial irrigation to grow long staple cotton by the British. This has changed. Large-scale treatment programmes in the 1990s using single-dose oral medication contributed greatly to reducing the prevalence and severity of S. mansoni in the Delta.
Other effects
Sediment deposited in the reservoir is lowering the water storage capacity of Lake Nasser. The reservoir storage capacity is 162 km3, including 31 km3 dead storage at the bottom of the lake below 147 m (482 ft) above sea level, 90 km3 live storage, and 41 km3 of storage for high flood waters above 175 m (574 ft) above sea level. The annual sediment load of the Nile is about 134 million tons. This means that the dead storage volume would be filled up after 300–500 years if the sediment accumulated at the same rate throughout the area of the lake. Obviously sediment accumulates much faster at the upper reaches of the lake, where sedimentation has already affected the live storage zone.
Before the construction of the High Dam, the 50,000 km (31,000 mi) of irrigation and drainage canals in Egypt had to be dredged regularly to remove sediments. After construction of the dam, aquatic weeds grew much faster in the clearer water, helped by fertilizer residues. The total length of the infested waterways was about 27,000 km (17,000 mi) in the mid-1990s. Weeds have been gradually brought under control by manual, mechanical and biological methods.
Mediterranean fishing and brackish water lake fishery declined after the dam was finished because nutrients that flowed down the Nile to the Mediterranean were trapped behind the dam. For example, the sardine catch off the Egyptian coast declined from 18,000 tons in 1962 to a mere 460 tons in 1968, but then gradually recovered to 8,590 tons in 1992. A scientific article in the mid-1990s noted that "the mismatch between low primary productivity and relatively high levels of fish production in the region still presents a puzzle to scientists."
A concern before the construction of the High Dam had been the potential drop in river-bed level downstream of the Dam as the result of erosion caused by the flow of sediment-free water. Estimates by various national and international experts put this drop at between and 2 and 10 meters (6.6 and 32.8 ft). However, the actual drop has been measured at 0.3–0.7 meters (0.98–2.30 ft), much less than expected.[30]
The red-brick construction industry, which consisted of hundreds of factories that used Nile sediment deposits along the river, has also been negatively affected. Deprived of sediment, they started using the older alluvium of otherwise arable land taking out of production up to 120 square kilometers (46 sq mi) annually, with an estimated 1,000 square kilometers (390 sq mi) destroyed by 1984 when the government prohibited, "with only modest success," further excavation. According to one source, bricks are now being made from new techniques which use a sand-clay mixture and it has been argued that the mud-based brick industry would have suffered even if the dam had not been built.
Because of the lower turbidity of the water sunlight penetrates deeper in the Nile water. Because of this and the increased presence of nutrients from fertilizers in the water, more algae grow in the Nile. This in turn increases the costs of drinking water treatment. Apparently few experts had expected that water quality in the Nile would actually decrease because of the High Dam.
Appraisal of the Project
Although it is moot whether the project constitutes the best use of the funds spent, the Aswan Dam project unquestionably is and will continue to be economically beneficial to Egypt. The project has been expensive and it took considerable time to complete, as is usually the case with large hydroelectric developments, But Egypt now has a valuable asset with a long life and low operating costs. Even so, the wisdom of concentrating one-third of domestic saving and most of available foreign aid on a slow growth project is questionable. Since 1960, GNP has grown 50%, but mainly as a result of other investment.
Egyptian authorities were well aware that equivalent gains in output could have been achieved more quickly and more cheaply by other means. A series of low dams, similar to the barrages now contemplated, was suggested by Egyptian engineers as a more economical means of achieving up to 2,000 mW of additional generating capacity, US and WorldBank agricultural experts had long recommended improved drainage, introduction of hybrid seeds, and other such low-cost alternatives to land reclamation as a means of increasing agricultural output, In other areas, most notably the once efficient cotton textile industry, investment was needed to forestall an output decline, Implementation of these and other alternatives has been postponed rather than precluded by the High Dam project.
However, the decision to concentrate Egyptian savings and energies on the Aswan project for a decade was heavily based on non-economic factors. Nasser undoubtedly believed that a project of considerable symbolic appeal was needed to mobilize the population behind the government's economic goals, He also apparently felt that the East and West would be more easily persuaded to bid against each other for a project of this scope.
The Aswan High Dam made an appreciable contribution to Egyptian GNP, however the returns were well below what the planners had anticipated. The principal limiting factors on the High Dam's contribution to Egyptian output are a shortage of land suitable for reclamation, the high cost and long time required to bring reclaimed land to full productivity, and an inadequate water supply to meet power and irrigation goals simultaneously. The last limitation arises in part from the allocation in a 1959 agreement of more water to Sudan than was originally foreseen and in part from differences in the seasonal demand pattern of agriculture and the hydroelectric plant for the water. Irrigation requires very heavy use of water during summer months, while power generation needs peak during the winter. Ecological problems created by the dam, most of which were anticipated, have not seriously harmed the economy, although a few minor industries have been damaged.
The dam is, nonetheless, a viable project. Eventually the contribution to GNP equals as much as 20% of total investment. Moreover, the dam and associated projects provided returns that at least offset the cost of operation, repayment of foreign loans and amortisation of domestic loans.
