Water–energy–food nexus in a transboundary context: the Euphrates–Tigris river basin as a case study

Today the international community faces a set of complex, interrelated problems. Many of these problems are directly related to the issues of water, energy and food security. On a global scale, approximately 0.8 billion people lack a safe water supply (UNICEF, 2013); 1.3 billion people do not have access to electricity; and more than 1 billion people suffer from hunger (World Economic Forum, 2011). In this context, the water-energy-food (WEF) nexus has emerged as a useful concept to address this complex and interrelated nature of global resource problems.
