The Green Economy and the Water-Energy-Food Nexus

The Green Economy and the Water-Energy-Food Nexus argues that a variety of policies will be required to create synergies between the water-energy-food nexus sectors while reducing trade-offs in the development of a green economy. Despite rising demand for water, energy and food globally, the governance of water-energy-food sectors has generally remained separate with limited attention placed on the interactions that exist between...

Demand management reducing energy-water nexus pressures

Nearly half of all water withdrawn in the U.S. is used to cool thermoelectric power plants, ensuring they operate safely and efficiently: On average a kilowatt-hour of electricity requires 25 gallons of water to be withdrawn from rivers and lakes. However, changes in precipitation, increased risk of drought, reduced snowpack and changes in the timing of snowmelt will impact the availability of water for electricity production. Reduced...

Managing water-energy nexus pressures in the MENA region

The Middle East and North Africa (MENA) region is one of the most water scarce regions in the world. In 1950, per capita renewable water resources were 4,000 cubic metres per year. Currently, this figure is 1,100 cubic metres and by 2050 it will drop to 550 cubic metres as a result of climate change and rapid urbanization. With water and wastewater services requiring energy and energy production requiring water, the MENA region faces...
