World Resources Institute
The World Resources Institute's global water-risk mapping platform. Assesses water stress, flood and drought risk by basin and country, under climate scenarios. An open reference for water exposure, both as a resource and a hazard.
Hydrological modelling combining observational data and climate projections, aggregated into composite risk indicators. The indicators are basin-scale proxies; they inform relative exposure rather than the expected loss of a specific site.
Use to map the water-stress exposure of a portfolio or supply chain. Relevant for physical-climate analysis and industrial underwriting.
