The beans are the main staple food and a major source of protein and calories for the population of Rwanda. Because of the limitation on the available agricultural land, the Government of Rwanda has put a lot of emphasis on the promotion of growing of climbing varieties of beans. It is estimated that between 50,000 to 100,000 hectares in Rwanda are under climbing bean variety.
The production and trade of beans has however not yet been formalised. There is a need to add value to the beans before the farmers sale on the market.
