Climate-Smart Agriculture: A Path to Sustainable Food Production

Climate-smart agriculture (CSA) is an integrated approach to farming that focuses on increasing agricultural productivity, enhancing resilience to climate change, and reducing greenhouse gas (GHG) emissions while ensuring sustainability and food security. This systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines explores the key role of CSA in addressing the challenges of climate change within the context of global food production. It investigates the impacts of climate change on agriculture, emphasizing disruptions to weather patterns, extreme events, and the consequent threats to food security. The paper discusses the core principles of CSA, highlighting sustainable intensification, climate resilience, and reduced greenhouse gas emissions after an in-depth analysis of 20 articles selected based on predefined inclusion criteria. Moreover, a range of CSA practices and technologies is evaluated with a specific emphasis on research conducted over the past five years. In addition, insights into the potential of CSA practices are provided to enhance agricultural productivity while maintaining environmental sustainability. Case studies from diverse regions demonstrating the practical benefits of CSA are also included in the review. Furthermore, the paper addresses policy support and existing challenges in promoting CSA, as reported during 2018-2023. Finally, it emphasizes the need for future advancements and interdisciplinary collaboration to mitigate the negative impact of climate change on global food security. This comprehensive study lays the foundation for implementing a sustainable and resilient framework by transforming conventional agriculture into CSA.
