The Energy-Water-Food Nexus and Climate Change: Implications for Policy-making, Research, and Business

By Mohamed Behnassi. Energy, water and food resource systems are critically inter depended. Energy is needed to produce food and to treat and move water; water is needed to cultivate food crops and to generate many forms of energy; and food is vital for supporting the growing global population that both generates and relies on energy and water services. In addition, land availability is an important element in each of these three resource systems. Even if this interdependence is currently perceptible and defined as the “energy-water-food nexus”, these three individual resource systems are still organized, managed and researched more or less independently.
