Resumen
Descripción
While population growth and economic development are putting unprecedented pressure on renewable, but finite water resources, especially in arid regions, scarce land and water resources are affecting food security and sustainable water management. FAO identified the need to implement a digital database built upon remote sensing and information technologies that can monitor and report on agricultural water productivity over Africa and Near East, accessible through the FAO Water Productivity through Open access of Remotely sensed derived data portal (WaPOR).
The WaPOR database is now operational at continental level (all African and Near East countries covered by the 250 m spatial resolution data), national level (two beneficiary countries can access the WaPOR database at 100 m resolution) and subnational level with a spatial resolution of about 30 m, so far including eight areas of interest (river basins or irrigation schemes). Water Accounting Plus (WA+) reports based on remote sensing have been completed for three river basins as planned (Litani in Lebanon, Awash in Ethiopia and Jordan basin). An action framework at national level for capacity building and participatory decision making is currently being developed to make effective a “demand-driven” approach based on national and local needs.
