The project is an extension of work done by the Global Water Systems Project (GWSP), published in Nature in 2010 . Several refinements and extensions are being made to the original work, including mapping threats to humans and ecosystems into the future using scenarios developed within the Water Futures and Solutions Initiative.
In 2014 WAT delivered finalized driver data, indicators and scenarios, quantified scenario projections of water availability, changes in irrigated areas and land use, and water demands. Human water security and downstream population served by areas with different incident threat scores were mapped.
