Resumen
Descripción
Producing our daily food requires one thousand times more water than we use to drink and one hundred times more than we use to meet our basic personal needs. Rainfed agriculture alone cannot ensure global food supply, and up to 70 percent of the water we take from rivers and aquifers goes into irrigated agriculture. Agriculture is the major source of food and by far the largest consumer of water on the globe. What is the role of water in the world's food production? What are the contributions to food contribution from rainfed and irrigated agriculture and from fisheries? How can more food be produced with the same amount of water? What role does the market play? How does food security connect to poverty and water use? This report discusses these and any other questions using up-to-date information and state-of-the-art knowledge. The United Nations World Water Development Report and its various thematic components provide a periodic review of the world's freshwater resources and th e way we steward them. Chapter 8 of the Report is re-issued here as Agriculture, food and water.
