Energy is required for pumping and treating water

Energy is required for two components of water provision: pumping and treatment (before and after use). Electricity costs are estimated at 5% to 30% of the total operating cost of water and wastewater utilities, but in some developing countries such as India and Bangladesh, it is as high as 40% of the total operating cost.

As of 2011, one third of the global food production is lost or wasted annually

As of 2011, 1.3 billion tons of food, about one third of the global food production, are lost or wasted annually. Per capita food waste by consumers in Europe and North-America is estimated at 95-115 kg/year, while this figure in Sub-Saharan Africa and South/Southeast Asia is only 6-11 kg/year. This wreaks significant harm on natural resources, including water.
