The Water-Energy-Food Nexus. A New Approach in Support of Food Security and Sustainable Agriculture

Issue Paper

If a decision is made at the national level to increase the share of bioenergy, what implications does this have for water, land and energy? How do electricity subsidies contribute to groundwater depletion and what can be done about it? How can we ensure that sectoral policies and strategies consider the potential trade-offs for other sectors? Finding answers to these questions is the main challenge of the Water-Energy-Food Nexus. By describing the complex and interrelated nature of our global resource systems, the Nexus approach helps us to better understand and systematically analyze how we can use and manage our resources in light of different, often competing interests and goals.
