International Freshwater Treaties Database

Search the Database

A searchable database of summaries and/or the full text of more than 600 international, freshwater-related agreements, covering the years 1820 to 2007. Documents are coded by the basin and countries involved, date signed, treaty topic, allocation measures, conflict resolution mechanisms, and non-water linkages. Both English and non-English language agreements are included. Where available, translations to English of non-English language documents are provided.

The agreements collected relate to international freshwater resources, where the concern is water as a scarce or consumable resource, a quantity to be managed, or an ecosystem to be improved or maintained. Documents concerning navigation rights and tariffs, division of fishing rights, and delineation of rivers as borders or other territorial concerns are not included, unless freshwater as a resource is also mentioned in the document, or physical changes are being made that may impact the hydrology of the river system (e.g., dredging of river bed to improve navigation, straightening of a river's course). In large part, the documents in the database concern: water rights, water allocations, water pollution, principles for equitably addressing water needs, hydropower/reservoir/flood control development, and environmental issues and the rights of riverine ecological systems.
