What data do you provide?

Aqueduct's global water risk mapping tool helps companies, investors, governments, and other users understand where and how water risks and opportunities are emerging worldwide. The Aqueduct Water Risk Atlas uses a robust, peer reviewed methodology and the best-available data to create high-resolution, customizable global maps of water risk. The Atlas maps aggregated scores of 12 key water indicators in 15,000 watersheds around the world. 

An updated version of the Aqueduct Water Risk Atlas will be launched in August 2019. Follow Aqueduct’s Twitter or subscribe to the newsletter for updates. Contact with questions.
