Climate-smart agriculture (CSA) represents a transformative approach to addressing the dual challenges of climate change and food security through sustainable farming systems. This comprehensive analysis examines the pathways to implementing CSA practices that simultaneously increase agricultural productivity, enhance climate resilience, and reduce greenhouse gas emissions. With global temperatures rising and extreme weather events becoming more frequent, agricultural systems must adapt while contributing to climate mitigation efforts. This review explores innovative technologies, management practices, and policy frameworks that enable the transition toward climate-smart farming systems capable of sustaining food production under changing climatic conditions.
