Agricultural water productivity for irrigated areas in 2008

Abstract

The dataset contains one of the layers produced for “Supporting Coordination and Cooperation in Water Management in the Euphrates and Tigris Area CPET” project. The project aims to assess the status of water use in agriculture in the Euphrates-Tigress basin, determine and map the agricultural water productivity and identify options for improving it in problem areas of the basin in Turkey, Syria and Iraq. Agricultural Water Productivity (WPM) (kg/m3) was determined for each pixel by dividing crop productivity (kg/ha) raster layer by seasonal crop water use in terms of actual evapotranspiration (m3/ha) raster layer. The WPM was for 2008, which was dry year and hence considered a deficit period based on the annual mean precipitation data at the basin level estimated by SIWI. The irrigated areas were determined based on IWMI’s irrigated and rainfed area mapping procedures.
