Mapping global karst groundwater: a tool to enhance water security

Sunday 26 August | 12.00-12.45 | Room: NL 253

Karst aquifers constitute valuable freshwater resources for hundreds of millions of people worldwide and many large cities such as Rome, Damascus and Taiyuan. In the context of climate change and population growth, the pressure on these freshwater resources is expected to increase. Many karst aquifer systems are connected over large areas and are shared by several countries. Examples are the Dinaric Karst System in South-East Europe and the Southwest China Karst, one of the world’s largest karst regions shared between seven Chinese provinces and Vietnam. Karst is an exceptionally significant environmental area with specific ecosystems like caves and drylands that host a high biodiversity including rare and endemic species. Furthermore, karst aquifers act like a natural sink for carbon dioxide.
To raise awareness for an adapted management approach that considers the specific dynamic and the vulnerability of karst aquifer systems, the World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP) developed the World Karst Aquifer Map (WOKAM).
