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 4.0, 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.

Our Aqueduct tools include:

  • Aqueduct Water Risk Atlas, which maps and analyzes current and future water risks across locations;
  • Aqueduct Country Rankings, which allows decision-makers to understand and compare national and subnational water risks;
  • Aqueduct Food, which identifies current and future water risks to agriculture and food security; and
  • Aqueduct Floods, which identifies coastal and riverine flood risks, and analyzes the costs and benefits of investing in flood protection.

Over the past seven years, 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.
