Water, energy and food interactions–Challenges and opportunities

Gustaf OLSSON

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 5,   Pages 787-793 doi: 10.1007/s11783-013-0526-z

Abstract: Water and energy are inextricably linked, and as a consequence both have to be addressed together.This is called the water-energy nexus.and energy security are considered together.In this paper we examine water, energy and food security and their couplings.The nexus also creates conflicts between water use, energy extraction and generation as well as food
