“Assessing the Impact of the Green Revolution, 1960^–₄₀2000_24ya”, R. E. Evenson, D. Gollin2003-05-02 (AI, economics)⁠:

We summarize the findings of a recently completed study of the productivity impacts of international crop genetic improvement research in developing countries [ie. the Green Revolution].

Over the period 1960^–₄₀2000_24ya, international agricultural research centers, in collaboration with national research programs, contributed to the development of “modern varieties” for many crops. These varieties have contributed to large increases in crop production.

Productivity gains, however, have been uneven across crops and regions. Consumers generally benefited from declines in food prices. Farmers benefited only where cost reductions exceeded price reductions.
