Abstract
SUMMARY Crop yields experienced significant increases in much of the world over the last 30 years, in large part due to investment in agricultural research, irrigation, and rural infrastructure. However, recent declines in yield growth are major causes of concern for future food security. Especially in Asia and sub-Saharan Africa the future prospects for food production are problematic. Both regions must meet strong growth in food demand–driven mainly by income growth in Asia and by population growth in sub-Saharan Africa. The production challenges in the two regions are fundamentally different: much of Asia is facing post-Green Revolution challenges of how to sustain crop yield growth following widespread adoption of modern varieties while dealing with environmental degradation in some high intensity crop production systems. Sub-Saharan Africa has yet to experience a Green Revolution, and must boost crop yield growth in the face of less favorable agroclimatic environments than in Green Revolution breadba...
