Climate-Smart Agriculture: Strategies for Enhancing Food Security under Climate Change

Abstract

Climate change poses a significant threat to global agricultural systems, with far-reaching implications for food security, particularly in regions heavily dependent on climate-sensitive farming practices. Rising temperatures, erratic rainfall patterns, prolonged droughts, and increased frequency of extreme weather events continue to disrupt agricultural productivity and threaten the livelihoods of farming communities. In response to these challenges, climate-smart agriculture (CSA) has emerged as a comprehensive approach aimed at transforming and reorienting agricultural systems to support sustainable food production under changing climatic conditions. This study reviews the concept and key strategies of climate-smart agriculture and examines their role in enhancing food security in the context of climate change. The study adopts a systematic review approach, synthesizing existing scholarly literature, policy reports, and empirical studies on climate-smart agricultural practices and their effectiveness in improving agricultural resilience and productivity. The review highlights major CSA strategies including conservation agriculture, improved crop varieties, efficient water management, agroforestry, climate-resilient livestock systems, and the use of digital climate information services. The findings indicate that these strategies contribute significantly to enhancing farm productivity, strengthening adaptive capacity, reducing greenhouse gas emissions, and improving the sustainability of food systems. Furthermore, the review underscores the importance of supportive policies, institutional frameworks, farmer education, and access to financial and technological resources in scaling climate-smart agricultural practices. The study concludes that climate-smart agriculture offers a viable pathway for addressing the dual challenges of climate change and food insecurity. However, broader adoption requires coordinated efforts among governments, research institutions, development organizations, and farming communities. Strengthening investment in climate-resilient agricultural innovations and knowledge dissemination will be critical for ensuring sustainable food production and global food security in the face of a changing climate.
