This document reviews research on assessing irrigation system performance using remote sensing. It discusses how remote sensing can be used to evaluate performance indicators and quantify parameters like adequacy, equity, reliability and efficiency. The document summarizes several studies that have evaluated irrigation systems in various countries using remote sensing data and models combined with performance indicators. It concludes that remote sensing allows objective, systematic evaluation of irrigation performance at larger scales than traditional field studies. Remote sensing can reveal spatial variations in factors like productivity and help identify problems in water distribution.
