The Aqueduct 4.0 Global Water Risk dataset from the World Resources Institute (WRI) is now available in ArcGIS Living Atlas of the World. 
Aqueduct 4.0 translates complex hydrological model outputs from PCR-GLOBWB 2 into intuitive water risk indicators at HydroSHEDS v1 level 6, with aggregations at provincial, state, and national levels. This comprehensive framework assesses both current conditions and future projections of water resources to inform decision-making.
