Measuring Water Use with Remote Sensing

Abstract

Remote sensing technology is a powerful tool that revolutionizes understanding of basin water resources. Water accounting—knowing how much water is available and who is using how much—is critical at a time when Asia is facing increasing water insecurity. In a pioneering collaborative study, a research team from IHE Delft Institute for Water Education (IHE Delft) (box, page 2) is working closely with Asian Development Bank (ADB) operations departments, using remote sensing to understand how water resources are used in project sites in six countries: Cambodia, India, Indonesia, Pakistan, Sri Lanka, and Viet Nam.
