With the goal of producing information for decadal-scale planning, adaptation, and investment, the Aqueduct Water Stress Projections model potential changes in future demand and supply of water over the next 3 decades. Global indicators were developed for water demand (withdrawal and consumptive use), water supply, water stress (the ratio of water withdrawal to supply), and intra-annual (seasonal) variability for the periods centered on 2020, 2030, and 2040 for each of 2 climate scenarios, RCP4.5 and RCP8.5, and 2 shared socioeconomic pathways, SSP2 and SSP3. Estimates were derived from general circulation models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5) and mixed-effects regression models based on projected socioeconomic variables from the International Institute for Applied Systems Analysis’s Shared Socioeconomic Pathways (SSP) database.
