Abstract:This paper reviews and summarizes the evidence of impacts of major food crops' improvement research in Africa availabe to date. It provides evidence of increased availability of improved varieties of major food crops to African farmers, increased food production in regions where adoption of improved varieties has occurred, and positive returns to research investment, indicating that agricultural research in Africa has had productivity increasing impacts on agriculture. The information available, however, is not uniformly comprehensive across all the major food crops of Africa. Hence, the review covers major cereal food crops, namely, maize, wheat, rice, sorghum and millet, in greater depth than other legume and roots and tuber food crops for which relatively few studies have been conducted. The paper points to a number of important issues, both internal and external to the agricultural research system organization, that need to be addressed if agricultural research is to provide a stimulus for modernizing African agriculture.
