This research extends the work of the Global Water Systems Project, published in Nature in 2010 , and includes several refinements to the original work, such as mapping future threats to humans and ecosystems using scenarios developed within the Water Futures and Solutions Initiative.
In 2014, WAT delivered a first set of various global drivers data, indicators and scenario storylines for the ongoing Shared Socioeconomic Pathways (SSP) assessment process. The program’s researchers also developed projections of water availability, changes to irrigated area, and cropland use for a Middle of the Road (SSP2) scenario and provided spatially detailed trajectories of crop and livestock production intensity. This work served in 2015 as input data for mapping human water security. Furthermore, projections of the global food and agriculture system were used in two additional SSP scenarios, Sustainability (SSP1) and Regional Rivalry (SSP3).
WAT’s work has continued to improve understanding of the geography of water-related ecosystem services, while accounting for both biophysical and economic controls on services.
