Agroforestry for Climate Mitigation, Resilient Farming, and Food Security

Abstract

Agroforestry systems offer a sustainable land management approach that integrates trees, crops, and livestock to enhance productivity, resilience, and ecosystem services. This review explores the multifunctional benefits of agroforestry, including its potential for climate change mitigation, resilient agriculture, and food security. Agroforestry practices such as alley cropping, silvopasture, and multistrata systems contribute to carbon sequestration, soil fertility improvement, and biodiversity conservation. The global distribution and adoption of agroforestry vary across regions, influenced by climatic conditions, socio-economic factors, and ecological objectives. Agroforestry plays a crucial role in mitigating climate change by sequestering carbon in biomass and soil, with sequestration rates ranging from 1.5 to 7.2 tons of CO₂ per hectare per year, depending on the system and management practices. Agroforestry reduces greenhouse gas emissions by decreasing the need for chemical fertilizers and improving livestock management. Agroforestry enhances ecosystem resilience by increasing biodiversity, improving soil health, and providing multiple ecosystem services. It also contributes to food security by diversifying food sources, increasing crop yields, and providing economic benefits to farmers. However, the adoption of agroforestry faces challenges related to socio-economic constraints, land tenure issues, and limited policy support. Future developments in agroforestry management involve precision agriculture, biotechnology, and digital platforms to improve sustainability and productivity. Recommendations for promoting agroforestry include integrating it into national and global climate policies, establishing public-private partnerships, and conducting long-term interdisciplinary research. Agroforestry offers a promising solution for sustainable land management, climate change mitigation, and food security, but its widespread adoption requires supportive policies, investments, and capacity building.
