Growing
In May 1971, 18 countries and organizations, convinced that agricultural science was a powerful tool for combating hunger, joined forces in the CGIAR. Other governments and institutions rallied to the idea and our membership grew rapidly.

Diversifying
Over the years our membership became more diverse. More countries in the developing world joined as well as other development agencies and foundations.
