Map of rainfed areas in 2017

Abstract

IWMI’s global irrigated and rainfed area maps (GIAM and GMRCA, Biradar et al., 2009, Thenkabail et al., 2009) have ben merge with released irrigated area maps accessible online; http://waterdata.iwmi.org/applications/irri_area/to fill the gaps and produce irrigated area and rainfed area map by combined the related classes. Thus, the output map has two classes irrigated areas and rainfed areas each class have been used as a mask for the Actual Evapotranspiration, yield and water productivity layers. The layer was resample to be used in further calculation. The Irrigated and rainfed areas layer was 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.
