IAH’s Commission on Groundwater and Climate Change (CGCC) is an official network of International Association of Hydrogeologists (IAH). Created in 2002, the aims of the commission are:

  • to improve understanding of the relationship between groundwater and climate change, and
  • to investigate the role of groundwater in adaptation to climate variability and change.

We hope our website will encourage you to find out more about the commission, our mission and our challenges, explore our activities and also to become involved.

IAH is an international charitable organisation that promotes sound development and management of groundwater – seen by many as the worldwide family of hydrogeologists.

Special Announcement

The International Water Resources Association (IWRA), jointly with UNESCO Intergovernmental Hydrological Programme (IHP), and supported by the International Association of Hydrogeologists (IAH), is excited to invite you to register for IWRA’s Online Conference on “Addressing Groundwater Resilience under Climate Change” to take place from Wednesday, October 28th to Friday, October 30th 2020. We are pleased to confirm that CGCC representatives have been involved in the organisation of this event, and encourage you to participate!

Thanks to the generous support of UNESCO-IHP to this online water event, IWRA has been able to grant free access for all registered attendees. We particularly welcome participation by experts from Africa, low income countries, women and youth. This support will also ensure open access to all conference related materials.

Currently, climate change has become an undeniable major pressure on the world’s freshwater resources. Yet, the effects of climate change on groundwater, the most significant freshwater resource on Earth, are still poorly understood. Somewhat neglected by policymakers and ignored by the public, groundwater management, governance and monitoring are less developed compared to surface water, globally. More up-to-date research and knowledge generation and sharing, as well as more efforts to raise awareness of the links between groundwater and climate change are also critical to ensure the sustainable management of this vital resource.

The online conference will address these challenges and priorities in order to manage resiliently groundwater resources under climate change. This conference’s main goal is to, ultimately, promote the sharing and exchange of state-of-the-art scientific and policy knowledge on the links between an increased resilience of groundwater resources and climate change for the sustainable governance, use and management of these resources in all regions of the world.
