The water-food-energy nexus

Water security, food security and energy security are chronic impediments to economic growth and social stability. Water, food, and energy are interrelated: food production requires water and energy; water extraction and distribution requires energy; and energy production requires water. Food prices are also highly sensitive to the cost of energy inputs through fertilizers, irrigation, transport and processing.
 This video of World Economic Forum Global Risks 2011 highlights the issues related to water-food-energy nexus, and provides recommendations in addressing and managing the nexus.
