Remote sensing for water productivity


WA+ is a water accounting system developed by UNESCO-IHE, IWMI and FAO that reports on the availability and use of water at basin level. It is essentially based on open-access satellite measurements, allowing computing of water consumption, flows, fluxes and storages by land and water use class. The approach makes a distinction between beneficial and non-beneficial, and consumptive and non-consumptive uses of water. The system is available through a dedicated platform.
