Welcome to IAH’s Commission on Transboundary Aquifers (IAH-TBA). As part of UNESCO’s ISARM Programme our aim is to further promote the complete scientific assessments of transboundary aquifers, and develop shared governance and science-based management of aquifers that traverse political boundaries. As well as addressing international transboundary aquifers, IAH-TBA will additionally consider governance and management mechanisms for intra-national transboundary aquifers.

Vision and objectives

A key perspective for IAH-TBA is to consolidate and support the adoption of the UN’s Draft Articles on the Law of Transboundary Aquifers, by promoting and supporting ad-hoc local- to intermediate-scale memoranda of understanding for cooperation, including protocols and informal arrangements. We aim to do this by three key objectives:

  1. Support the management of transboundary aquifers aimed at improving shared sustainable use of groundwater resources that cross two or more jurisdictional borders.
  2. Provide advanced scientific, social, policy and legal recommendations to UN Agencies, international and national organisations and governments worldwide.
  3. Increase the generation and exchange of knowledge regarding transboundary aquifers, creating channels of communication and cooperation.​

LinkedIn Discussion Group

To encourage discussion about transboundary aquifer among hydrogeologists, the commission initiated this LinkedIn group.
