Water is intricately linked with food security, energy security, and sustainable development. As the world is moving towards sustainable development goals, it is critical to recognize the role of water in attaining these goals. The Water-Energy-Food Nexus draws attention to the complex and interrelated nature of global resource systems and forces us to think about how a decision in one sector impacts other interlinked sectors as well. This book looks at the three dimensions of sustainable developmentenvironment, economics and society – and how water is linked with them and explores the nexus approach as a framework to look at the issues and identify solutions.
