Facts and Figures on Upland NERICA
•Africa Rice Center (AfricaRice) scientists in association with their partners were able to successfully cross two species of cultivated rice—Oryza sativa (Asian rice) and O. glaberrima (African rice). This is a formidable scientific challenge because the two species have evolved separately over millennia and are so different that many previous attempts did not lead to reliable variety development. Using conventional and molecular biology techniques, the scientists overcame hybrid sterility—the main problem in crossing the species. This also allowed them to accelerate the breeding process from 5–7 years to 2 years or less. The fruit of this effort was the New Rice for Africa (NERICA), which presents several advantages over traditional varieties.
•NERICA is not just one variety; several hundred family lines have been generated. The development of NERICA varieties for various rice ecologies is a significant international public good.
•NERICA lines had been tested in 31 SSA countries. Farmers were exposed to NERICA varieties through the use of Participatory Varietal Selection (PVS) and Community-Based Seed Systems (CBSS).
•During the period 2000–2006, AfricaRice designated 18 upland NERICA and 60 lowland NERICA-L varieties. More than 1.4 million ha are under upland NERICA production in Africa ((Arouna et al. 2017).
•NERICAs have brought specific benefits to African rice growers, in particular shorter growth duration and tolerance to specific biotic and abiotic stresses, while giving them yield that is generally as good as the high-yield potential O. sativa varieties.
•A study (Arouna et al. 2017) has shown that about 8 million people were lifted out of poverty and 7.2 million people out of food insecurity thanks to the adoption of improved rice varieties, including NERICA, which brought hope to millions of poor small-scale farmers in Africa by reducing poverty and income inequality. The impact of NERICA adoption on poverty reduction has been well documented in Benin and Uganda.
