Significance Africa’s “forgotten” food crops could support more climate-resilient and healthful food systems in sub-Saharan Africa (SSA), but the promotion of these crops has received limited attention. Projecting forward to the year 2070, we show that a prioritized collection of these crops, differentiated by food groups, has high potential to diversify cropping systems of major staples to support climate-resilience and nutrition in the SSA region. Our analysis, contextualized by subregions within SSA as a whole, informs practitioners, researchers, and policymakers on the use of Africa’s forgotten food crops in the diversification of food supply for healthy diets in a changing climate.
