Abstract

The Water-Energy-Food Nexus (WEF Nexus) addresses the interrelated nature of our global natural resource systems. The WEF Nexus is a key topic in the post-2015 sustainable development agenda, and it aims to tackle simultaneously different issues, such as food and water security, the connection between global warming and water scarcity, and between climate change and food production, as well as energy security, and the connection between energy production and water and land use. Global projections indicate that demand for freshwater, energy and food will increase significantly over the next decades under the pressure of population growth, economic development, urbanization, technological changes, and climate change. A series of solutions are proposed and some best practices at the international level on the coordinated use of water and energy are presented.
