Africa faces a persistent food security crisis driven by climate change, land degradation, rapid population growth, and structural weaknesses in agricultural systems, resulting in widening yield gaps and heightened vulnerability of smallholder farmers across diverse agro-ecological zones. Despite numerous local studies on climate-smart agriculture and resilience interventions, a comprehensive synthesis of scalable, region-specific strategies linking crop production, policy frameworks, and institutional support is lacking. This study addresses this gap by systematically reviewing evidence from national agricultural statistics, FAO and World Bank datasets, peer-reviewed research, and regional case studies (2008–2024) across East, West, Central, Southern, and North Africa. Quantitative findings indicate that climate-related yield losses in staple crops range from 20 to 60% in rain-fed systems, while adoption of climate-resilient practicessuch as improved seed varieties, conservation agriculture, and water-efficient technologies, yields gains of 15–40% and stabilizes production under climatic stress. Countries with coordinated policy frameworks and strong institutional support exhibit higher adoption rates and reduced productivity gaps. This case study review highlights the need for targeted investments in resilient seed systems, farmer extension services, water-efficient technologies, and region-specific adaptation strategies. We proposed that integrating climate resilience agricultural practices into national agricultural policies is essential to reduce food insecurity and ensure sustainable crop production under increasing climatic uncertainty.
