The Food-Energy-Water Nexus: A Framework to Address Sustainable Development in the Tropics

Interactions between agriculture, energy, and tropical environments occur within a larger, interconnected food-energy-water (FEW) system context. These interactions both affect and are shaped by the FEW nexus (connected FEW natural processes, engineering and infrastructure, and institutions and governance), motivating the collective inclusion of many processes and institutions in the discussion of any individual member. Moreover, the important role of the tropics in the global environment and global food security raises the stakes of management, providing further impetus for a thorough, FEW nexus approach. We herein discuss FEW issues which are key to proper FEW nexus management in the tropics, including fundamental earth system processes, agricultural expansion and deforestation, the potential benefits and drawbacks of hydropower development, and technology and policy advancements.
