Aqueduct's Water Risk Atlas (a) identifies and maps open-source, globally comparable information on water risks like floods, droughts and water stress, (b) allows users to identify and prioritise locations facing the highest physical (water quantity and quality), regulatory, and reputational water risks, and (c) advances best practices in water-resource management to ensure sustainable growth in a water-constrained world.
The Atlas uses a robust, peer reviewed methodology and the best-available data to create high-resolution, customizable global maps of water risk. It is part of the Aqueduct Platform, a data platform run by the World Resources Institute (WRI).

Strengths and weaknesses, comparative added value to other similar tools
Strengths:
(+) Aqueduct is useful for comparing risks across large geographies because it uses globally consistent data and methods.
(+) Its strengths are in screening and prioritizing water risks.
Weaknesses:
(-) Aqueduct has limited applicability at the local level. Users are encouraged to supplement Aqueduct data with local water risk data for identified priority locations.
(-) Additionally, Aqueduct’s hydrological model does not consider inter-basin transfers of water or non-renewable resources like fossil groundwater, and the water stress indicator does not explicitly take into account environmental flow requirements.
For a full list of limitations, please consult the Aqueduct 4.0 technical note.
Integration:
Aqueduct’s risk indicators can be integrated with indicators from other tools, such as WWF’s Biodiversity Risk Filter.
Input(s)
For the regional level, the users can readily use the tool.
If the users want to use the tool for the local scale they need to upload addresses or coordinates of their locations if they would like to compare risks across specific sites.
Output(s)
The tool generates maps with selected water risk indicators at the HydroSHEDS 6 catchment level. Users can visualise their locations overlayed with selected water risks, can download the datadata as tables (CSV) and geospatial formats.
Replicability: Cost/effort for (new) usage
None. The tool provides global data across all regions with available data sources.
The Aqueduct team can explore developing a localized model for a specific region. Costs will vary.
