Water-Energy-Food-Ecosystem (WEFE) Nexus: A key concept for a more resilient adaptation to the climate crisis

Abstract

The Water-Energy-Food-Ecosystem (WEFE) Nexus is a pretty novel cross-thinking concept, meaning that answers to current environmental hazards must follow a multisectoral approach rather than a traditional unidirectional vision[1]. Since water supply, energy flows, and food security—and its connection with the surrounding ecosystems—are intimately linked together, every impact in one of such areas will have undoubtedly impacts on the others. The most important signifi-cance of the WEFE Nexus approach is that further exploitation of clean water supplies, agricultural soils, and energy resources should not de-stabilize nor weaken the provision of these ecoservices to the current and future societies. ...
