These maps show projected change in baseline water stress, Aqueduct’s measure of competition for limited water resources. They were originally published on Aqueduct in 2011. These older map uses water withdrawal data from the year 2000, while the maps in the Risk Atlas use withdrawal data from 2010.
The projected change in baseline water stress is based on three different scenarios of climate change and socio-economic development created by the IPCC: the A2, A1B, and B1 scenario. To learn more about these scenarios and their assumptions, visit the IPCC’s website. Data sources and methodology are summarized in the Freshwater Sustainability Analysis document.
These maps were donated to the Aqueduct project by The Coca-Cola Company.
The Coca-Cola Water Risk Data were provided to the World Resources Institute by The Coca-Cola Company in support of the Aqueduct project. ISciences L.L.C. performed the hydrological modeling.
