Essential information for the water sector

WA+ provides independent estimates of water flows, fluxes, stocks, consumption and services, that in the near-future becomes certified. It is a multi-institutional effort from international knowledge centers (IWMI, UNESCO-IHE, FAO, and WWAP) that are neither politically nor geographically connected to a given river basin.
