Researchers have released downscaled global estimates of irrigation water sources at a 60-meter resolution from 2000 to 2015. The data has been used in various studies to analyze water storage decline, soil moisture, and irrigation patterns in different regions, including the Indus Basin, Morocco, the Continental United States, Europe, and China. These studies suggest that irrigation expansion has occurred in water-stressed regions, but the specifics of the findings vary by location and methodology.
