African agriculture could be reshaped by shifting attention from high-yield staples to nutrient-rich, climate-resilient crops that better serve local diets and ecosystems, according to a new study published in Nature Food.
The researchers argue that decades of agricultural research in sub-Saharan Africa have focused disproportionately on rice, wheat and maize, often at the expense of nutrition, soil health and cultural relevance.
They propose a framework known as “crops that nourish,” which prioritises crops and farming systems that support human nutrition, withstand climate stress and improve soil fertility.
Kate Schneider Lecy, an assistant professor at Arizona State University’s School of Sustainability, said the approach links soil health directly to nutrition outcomes.
She explained that crops such as amaranth, millet and sorghum offer strong nutritional profiles while adapting well to changing climate conditions.
The study describes these traditional but underutilised crops as “opportunity crops,” noting their potential to strengthen both food security and environmental sustainability.
Researchers emphasised that unlocking this potential requires participatory, community-led research rather than top-down crop development.
They called for closer collaboration between farmers, plant breeders, nutrition experts and local communities through Participatory Action Research.
Sieglinde Snapp, a co-author and programme director at the International Maize And Wheat Improvement Center, said farmer involvement is essential to aligning crop innovation with household nutrition goals.
She said collaboration between seed breeders and smallholder farmers in semi-arid West Africa has already increased adoption of improved millet and sorghum varieties.
Despite promising results, the researchers identified weak market demand as a major barrier to scaling opportunity crops.
Lecy said limited infrastructure and high costs make it difficult to process and sell these crops at scale without private-sector investment.
She added that consumer awareness and demand are critical to encouraging farmers to grow nutrient-dense crops.
The study also urged governments to realign subsidies, insurance schemes and other policy tools to support diverse, climate-adapted crops.
According to the authors, transforming African food systems will require sustained investment in research, supportive policies and locally driven innovation.
They said prioritising crops that nourish could help shift diets, strengthen rural livelihoods and build resilience across African agriculture.
