Assessing the Impact of the Green Revolution, 1960 to 2000
R. E. Evenson* and
D. Gollin
We summarize the findings of a recently completed study of theproductivity impacts of international crop genetic improvementresearch in developing countries. Over the period 1960 to 2000,international agricultural research centers, in collaborationwith national research programs, contributed to the developmentof "modern varieties" for many crops. These varieties have contributedto large increases in crop production. Productivity gains, however,have been uneven across crops and regions. Consumers generallybenefited from declines in food prices. Farmers benefited onlywhere cost reductions exceeded price reductions.
