The impact of agricultural research in Tropical Africa; a study of the collaboration between the international and national research systems

The report is divided into two parts. Part A contains general considerations and sets the framework for the impact assessment. It introduces the problems research is faced with on the African continent and examines the present state of international and national agricultural research activities. Part B presents a detailed impact assessment concentrating on the collaboration between the CGIAR system and the national systems and discusses research impacts on agricultural production. This part relies heavily on information from the nine case studies of countries in tropical Africa: Burkina Faso (I.F. Ouali), Camerron (S.N. Lyonga), Ethiopia (A. Negewo, H. Shawel), Kenya (G. Ruigu), Malawi (K. Billing), Nigeria (D.E. Okoro, J.N. Onuoka), Senegal (D. Sene), Tanzania (B.Ndunguru), Zimbabwe (K. Billing). As will be evident, the country studies show that each country has individual problems of its own, and that generalizations are hazardous. In total, however, these studies offer a fairly comprehensive view of international agricultural research activities in tropical Africa. Considering the many top down reviews of the CGIAR system, these studies should be a useful source of information on future allocative decisions. This is one of the main reasons for the emphasis given to country studies in the overall impact study
