Adoption of Modern Varieties of Food Crops in Sub-Saharan Africa
ISPC, SPIA 2014
In the late 1990s, a global initiative on the impact assessment of crop varietal change estimated that modern varieties (MVs) accounted for about 22% of the growing area of primary food crops across Sub-Saharan Africa (SSA) (Evenson and Gollin, 2003). This baseline has recently been updated, widened, and deepened in the CGIAR’s project Diffusion and Impact of Improved Crop Varieties in Sub-Saharan Africa (DIIVA), supported by the Bill and Melinda Gates Foundation. Seven CGIAR Centers and more than 200 individuals – mainly crop improvement scientists in national programs – participated in the DIIVA project, which was directed and coordinated by the Standing Panel on Impact Assessment (SPIA) of the CGIAR and administrated through Bioversity International.
