Description

Aqueduct 4.0 is the latest iteration of WRI's water risk framework designed to translate complex hydrological data into intuitive indicators of water related risk. This dataset has curated 13 water risk indicators for quantity, quality and reputational concerns into a comprehensive framework. For 5 of the 13 indicators, a global hydrological model called PCR-GLOBWB 2 has been used to generate novel datasets on sub-basic water supply. The PCR-GLOBWB 2 model is also used to project future sub-basin water conditions using CMIP6 climate forcings. The projections center around three periods (2030, 2050, and 2080) under three future scenarios (business-as-usual SSP 3 RCP 7.0, optimistic SSP 1 RCP 2.6, and pessimistic SSP 5 RCP 8.5).

The water risk indicators have been aggregated by category (quantity, quality, reputational, and overall) into composite risk scores using sector-specific weighting schemes. In addition, select sub-basin scores have been aggregated into country and provincial administrative boundaries using a weighted average approach, where sub-basins with more demand have a higher influence over the final administrative score.

The WRI Aqueduct baseline monthly dataset provides monthly data on key water risk indicators which includes indicators such as baseline water stress, baseline water depletion and interannual variability.This monthly data allows for a more detailed analysis of water risk dynamics throughout the year, which is crucial for understanding seasonal water scarcity, planning for water management interventions, and adapting to changing water availability patterns.

This technical note explains in detail the framework, methodology, and data used in developing Aqueduct Floods.
