The international agricultural research centers; their impact on spending for national agricultural research and extension
Many CGIAR Centers have been in place for a number of years. Important changes, both in the development of CGIAR Centers and in national research and extension programs, have taken place over this period. Two important questions about the impact of the CGIAR Centers are addressed in this paper. The first is whether the existence of the CGIAR Centers has influenced the size and character of national research and extension programs. The second is whether the research in the CGIAR Centers and the national systems has had any impact on crop productivity. The study estimates that the CGIAR Centers have had a positive impact on investment in national research programs in each of the crops for which CGIAR crop research programs exist except cassava. Estimates for livestock and horticultural crop research programs show a significant positive CGIAR impact as well. National extension spending is also stimulated by CGIAR programs. These estimates are based on an econometric specification that takes into account the impact of several economic development aid initiatives in addition to the activities of the CGIAR impacts. The study estimates that CGIAR Center programs have had significant impacts on crop productivity for maize, millets, sorghum, rice, wheat, beans, cassava and potatoes in all the regions studied. National research programs have had a positive impact on crop productivity in most of these crops as well. In addition, national extension programs have been productive in some crops. These estimates are based on crop production data in 25 countries
