Agroforestry is a sustainable and multifunctional land-use system that integrates trees, crops, and livestock to enhance ecological stability, economic productivity, and social wellbeing. This article provides a comprehensive overview of agroforestry, highlighting its major systems, ecological functions, and socio-economic benefits. Agroforestry systems, including agrisilvicultural, silvopastoral, and agrisilvopastoral models, are designed to optimize resource use efficiency while mimicking natural ecosystems. The study emphasizes the critical role of agroforestry in improving soil fertility, conserving biodiversity, regulating microclimate, and sequestering carbon, thereby contributing significantly to climate change mitigation and adaptation. Furthermore, agroforestry enhances livelihood security by diversifying income sources, generating employment, and reducing risks associated with market and climatic uncertainties. The paper also discusses the relevance of agroforestry in the Indian context, including traditional practices and policy initiatives such as the National Agroforestry Policy (2014). Despite its numerous advantages, challenges such as policy constraints, lack of awareness, market limitations, and technical issues hinder its widespread adoption. The article concludes by underscoring the future potential of agroforestry in achieving sustainable development goals through technological innovations, supportive policies, and increased research efforts.
