Transboundary Aquifers

Transboundary aquifers (TBAs) are aquifers that underlie more than one country or political region. Management of TBA resources is therefore dependent on cooperation between countries and it is important that they are well understood to ensure they are exploited in a sustainable way.


As a United Nations Centre, the International Groundwater Resources Assessment Centre (IGRAC) is taking a global lead on assessing and providing information on transboundary aquifers. There are many initiatives looking at various aspects of transboundary groundwater, including global baseline assessments and more detailed regional or aquifer assessments. Further information can be found on the Transboundary Groundwaters section of IGRAC's website.

As part of their work on transboundary aquifers, IGRAC have led the production and publication of a map of Transboundary Aquifers of the World.
