Agroforestry: A Resource Conserving Technology for Efficient Utilization of Agricultural Inputs, Leads to Food and Environmental Security
摘要
The agroforestry system (AFS) is established for on-farm and off-farm revenues both from tree and crop production by utilizing natural resources. In AFS, trees plantation on farms affords various livelihood welfares and environmental sustainability. Earlier and contemporary evidence undoubtedly highlights that AFS is a viable land-use option for alleviating poverty and compromises several environmental benefits including carbon sequestration, conservation of biodiversity, improves soil health and enhances the quality of water and air. Considering the food security of the increasing population and the future projected climate change, AFS may be useful as a cost-effective resource to boost-up the sustainability of food production, and also mitigate the adverse of climate change. For developing countries both in the tropical and subtropical regions, AFS may be considered one of the suitable options because of its multifaceted benefits focusing on agricultural sustainability. The present review deals with the principles, practices, and advantages of AFS system for food and environmental security and agricultural sustainability.
