Producing more food requires more water and energy; many forms of energy production need water, we need water to cool power plants, refine crude oil and produce biofuels. (..) Managing water poorly can thus have a detrimental impact on energy supplies and agricultural production, and vice versa. Global warming, increasing urbanisation and growing consumption of water, energy and food continue to disrupt our already fragile ecosystem. (..) The outcomes of the upcoming Rio conference in 2012 should therefore adequately reflect the interdependencies between water, energy and food as well as their underlying natural resources: water, land and soil.
