Abstract: Climate change presents profound threats to global food security, particularly through declining yields and heightened variability in major staples such as maize, wheat, and rice. This study evaluates the potential of disadvantaged crop species—including finger millet, pearl millet, sorghum, amaranth, cowpea, and bambara groundnut—as climate-resilient and nutrition-sensitive alternatives. Using a mixed-methods approach that combined systematic literature review, secondary data analysis, and statistical comparisons, the research assessed yield performance, drought tolerance indices, variability, and composite nutrient density across disadvantaged and staple crops. Results revealed that disadvantaged crops consistently exhibited higher drought tolerance indices, with mean values 27% greater than staples, and displayed lower yield variability under stress conditions. Nutritional analyses further highlighted their superiority, with average nutrient density scores surpassing staples by more than 30 points on a 0-100 scale. These findings underscore the dual benefits of disadvantaged species in sustaining productivity under climatic stress and enhancing dietary diversity. The discussion integrates these empirical outcomes with broader agricultural and nutrition frameworks, identifying key gaps in policy support, research investment, and market integration. The study concludes that disadvantaged crops are not marginal, but essential for climate adaptation and sustainable food systems. Practical recommendations emphasize the need for targeted breeding programs, supportive policy frameworks, value-chain development, farmer training, and nutrition-sensitive public procurement. By systematically mainstreaming disadvantaged species into agricultural strategies, governments and communities can mitigate climate-induced food insecurity while promoting healthier, more resilient diets.
