N2Africa is a project that aims to improve nitrogen fixation to benefit smallholder farmers in Africa. It discusses the key achievements, challenges, opportunities, and lessons learned from ACOS Ethiopia's grain legume sourcing and export marketing experiences. Some of the key achievements include developing new legume varieties for export markets in partnership with EIAR, introducing contract farming, and exporting over 170,000 metric tons of various beans and crops. However, challenges include inadequate and low quality supply, a lack of price information, and insect damage reducing quality. Moving forward, opportunities exist in improving collection, sorting, and supplying a range of grains to international markets due to growing global demand and Ethiopia's geographic position.
