Use the Aqueduct™ tools to identify and evaluate water risks around the world.

Aqueduct’s tools map water risks such as floods, droughts, and stress, using open-source, peer reviewed data. Beyond the tools, the Aqueduct team works one-on-one with companies, governments, and research partners to help advance best practices in water resources management and enable sustainable growth in a water-constrained world.

Over the past six years, the Aqueduct tools have reached hundreds of thousands of users across the globe, and informed decision-makers in and beyond the water sector. Aqueduct data and insights have been featured in major media outlets including, the Economist, the Guardian, Bloomberg Businessweek, the New York Times and Vox’s Netflix show Explained.

This iteration of Aqueduct 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.

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: Netherlands Ministry of Foreign Affairs, Royal Danish Ministry of Foreign Affairs, and Swedish International Development Cooperation Agency.
