Water risks are an urgent global challenge. Most public health crises are already driven by water, including floods, droughts and water-borne diseases. Climate change is worsening the problem by intensifying floods and drought, shifting precipitation patterns, altering water supplies and accelerating glacial melt and sea level rise. Clean water supplies are vital for human health, industry, agriculture and energy production, making water risks a major humanitarian threat. Identifying, understanding and responding to these risks requires transparent, publicly available data.
Aqueduct’s tools use open-source, peer reviewed data to map water risks such as floods, droughts and stress. Beyond the tools, the Aqueduct team works one-on-one with companies, governments and research partners through the Aqueduct Alliance to help advance best practices in water resource management and enable sustainable growth in a water-constrained world.
The latest iteration of Aqueduct, Aqueduct 3.0, represents our most robust look at water risks to date, including more granular data, higher resolution, new indicators, improved tool function and access to underlying hydrological models.
Aqueduct is made possible by the support of the Aqueduct Alliance, a coalition of companies, governments and foundations at the cutting edge of water stewardship. Companies, governments and foundations are invited to join the Aqueduct Alliance to advance water stewardship best practice and the Aqueduct tools.
Aqueduct Food is made possible by support from Cargill and the Skoll Global Threats Fund.
We are also pleased to acknowledge our institutional strategic partners, who provide core funding to WRI:
