Decision-makers need future projections on water supply and demand. However, most of these decision-makers operate at the administrative or political scales, and therefore require country-level projections. This technical note utilized a spatial aggregation methodology to bring sub-catchment scale Aqueduct Water Stress Projections up to the country scale, fulfilling this need.
Both private and public sectors see the need to plan for potential changes in water availability caused by climate change and economic development.
The availability of freshwater resources to meet human demands has emerged as a top-tier global issue for both environment and development. However, many decision-makers lack the technical expertise to fully understand hydrological information.
This working paper updates the 2013 Aqueduct Global Maps 2.0 Metadata Document. It describes the data sources and calculations for the Aqueduct Water Risk Atlas Global Maps. Complete guidelines and processes for data collection, calculations, and mapping techniques are described in the Aqueduct Global Maps 2.1: Constructing Decision-Relevant Global Water Risk Indicators.
