Towards Understanding the Integrative Approach of the Water, Energy and Food Nexus

This wealth of publications is reviewed in an endeavor to (1) reveal the lines of justification for the need of the water energy food nexus (WEF nexus) debate and (2) identify the range of tools for analyzing the interdependent resource issues of the nexus using an integrated framework of science and policy. There are three drivers behind the emergence of the nexus thinking: (a) increasing resource interlinks due to growing scarcities, (b) recent resource supply crises and (c) failures of sector-driven management strategies.
