In Africa, like anywhere, hunger is driven by many interwoven factors, not all of which are a consequence of farming practices. Increasingly, though, policymakers on the continent are casting a critical eye toward the types of crops in farmers’ plots, especially the globally dominant and climate-vulnerable grains like rice, wheat, and above all, maize. Africa’s indigenous crops are often more nutritious and better suited to the hot and dry conditions that are becoming more prevalent, yet many have been neglected by science, which means they tend to be more vulnerable to diseases and pests and yield well below their theoretical potential.

Efforts to develop new varieties of many of these crops, by breeding for desired traits, have been in the works for decades—through state-backed institutions, a continent-wide research consortium, and underfunded scientists’ tinkering with hand-pollinated crosses. Now those endeavors have gotten a major boost: In 2023, the US Department of State, in partnership with the African Union, the [United Nations’ Food and Agriculture Organization], and several global agriculture institutions, launched the Vision for Adapted Crops and Soils, or VACS, a new Africa-focused initiative that seeks to accelerate research and development for traditional crops and help revive the region’s long-­depleted soils.
