Knowing where the irrigated areas are is of important implications in decision making processes for food security, poverty alleviation, water resources management, and environmental conservations. This site presents results of IWMI’s first attempt to map global irrigated and rainfed croplands for the nominal year of 2000 using satellite images. The products include 10 km irrigated and rainfed cropland and a LULC map for the globe, 500 meter irrigated area map for South Asia, and 30 meter irrigated area maps for Syr Darya River Basin in Central Asia and Krishna River Basin in India. The maps contain various levels of information including irrigation water sources (surface, groundwater), cropping intensity (single, double, continuous…) and dominant crop types. Detailed statistics and communication materials including posters and publications are also provided.
