| Abstract
|
Energy, water and food resource systems are fundamentally interrelated. We need energy to produce food and to treat and move water; we need water to cultivate food crops and to generate essentially any form of energy; and we need food to support the world’s growing population that both generates and relies on energy and water services. Land availability also constitutes an important element in each of these three resources, for example for crop production for either food or energy purposes. This mutual relationship is defined as the “Energy-Water-Food Nexus”.
This report begins by reviewing the current thinking reported in the existing literature on the “Energy-Water-Food Nexus” (hereafter, for reasons of brevity, simply referred to as the nexus). Given that the nexus constitutes a broad, recently emerging, and still largely undefined and poorly understood concept and associated field of research, we narrow down our focus to predominantly inspect the interrelationship between energy and water in the remainder of our report. We leave a more elaborate study of the connection of energy and water to the dimension of food for follow-up work. This report aims to inform local and regional decision-makers responsible for development and implementation of policies related to energy and water resource systems.
