Total Renewable Water Resources by Country
This map shows total renewable water resources by country. It corresponds to the maximum theoretical yearly amount of water actually available for a country at a given moment.

Current world total renewable water resources: ~310 km³ / year ( 310 billion liters )

Total renewable water resources provides the water total available to a country but does not include water resource totals that have been reserved for upstream or downstream countries through international agreements. Note that these values are averages and do not accurately reflect the total available in any given year. Annual available resources can vary greatly due to short-term and long-term climatic and weather variations.
