Water, energy, and food security challenges are complex and tightly interconnected (Hoff 2011; Mohtar and Daher 2012; FAO 2014a; IRENA 2015). Food production demands water; water extraction, treatment, and redistribution demand energy; and energy production requires water. With growing pressures on these interconnected resource systems due to climate change and population growth, it is critical that we understand and quantify those interlinkages to minimize the competition that might arise as different sectors plan for their future development. The water-energy-food nexus is an approach that offers an equidistant platform for multi-sectoral evidence-based dialogue about trade-offs associated with decisions made across the different sectors (Mohtar and Daher 2016). As countries work toward achieving the Sustainable Development Goals, the WEF Nexus approach could play a role in ensuring that decisions made across sectors do not advance goals at the expense of others.
