Use Aqueduct tools to identify and evaluate water risks around the world. Aqueduct Country Rankings, which allows decision-makers to understand and compare national and subnational water risks.

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.

This map shows countries and provinces’ average exposure to six of Aqueduct 3.0's water risk indicators: baseline water stress, riverine flood risk, and drought risk. Scores are also available for all industrial, agricultural, and domestic users' average exposure to each indicator in each country and province basin.

Water Risk Indicators:

  • Baseline Water Stress: Baseline water stress measures the ratio of total water withdrawals to available renewable water supplies. Water withdrawals include domestic, industrial, irrigation and livestock consumptive and non-consumptive uses. Available renewable water supplies include surface and groundwater supplies and considers the impact of upstream consumptive water users and large dams on downstream water availability. Higher values indicate more competition among users.
  • Drought Risk: Drought risk measures where droughts are likely to occur, the population and assets exposed, and the vulnerability of the population and assets to suffering adverse effects. Higher values indicate higher risk of drought.
  • Coastal Flood Risk: Coastal flood risk measures the percentage of population expected to be affected by coastal flooding in an average year, accounting for existing flood protection standards. Higher values indicate greater proportion of the population is expected to be impacted by coastal floods.
