April 6, 2009: IGRAC, the International Groundwater Resources Assessment Centre, presented the map 'Transboundary Aquifers of the World - update 2009' during a special meeting at World Water Forum 5 in Istanbul.

  • The map is about Transboundary Aquifers (TBAs). It shows the present state of information regarding the occurrence and extent of TBAs world-wide.
  • The intention of the map is to provide a global overview of these important shared water resources and to encourage their further assessment.
  • The back of the map contains an introduction to a methodology for assessment of TBAs


IGRAC would like to know your opinion on the map and the proposed methodology for assessment.
