This review synthesizes evidence from case studies across Nigeria, Sierra Leone, Senegal, Ghana, and Burkina Faso, demonstrating that adaptation strategies such as optimized planting dates and climate-resilient varieties, can offset losses by 13–19%, though their efficacy is highly context-specific and constrained by socio-economic barriers like limited access to credit and extension services. Policy implementation, while promising in instances like Senegal’s large-scale irrigation schemes, is often hindered by inadequate resources and weak institutional capacity. Critical research gaps persist, including a need for longitudinal studies on adaptation sustainability, frameworks for integrating Indigenous knowledge with scientific forecasting, and gendered impact analyses. Addressing these gaps through genomics-assisted breeding, decentralized climate services, and financial mechanisms is imperative for developing evidence-based, localized policies that bolster resilience and secure food production across the region’s diverse agro-ecologies.enMetadata only.
