With water becoming increasingly scarce and irrigated agriculture already accounting for 70 percent of global water withdrawals, governments around the world are supporting efforts to improve the performance of water use in agriculture. The Food and Agriculture Organization of the United Nations (FAO) and its partners have invested in developing databases and tools that apply remote sensing in agricultural water management, with a focus on low-income and data-scarce contexts. This brief was produced under the FAO-World Bank Cooperative Progamme and proposes concrete applications of the FAO-developed tool: WaPOR – Water Productivity through Open access of Remotely sensed derived data portal.
