Atlas of Transboundary Aquifers

The worldwide Internationally Shared Aquifer Resources Management (ISARM) Initiative is an UNESCO and IAH led multi-agency effort aimed at improving the understanding of scientific, socio-economic, legal, institutional and environmental issues related to the management of transboundary aquifers. Since its start in 2000, ISARM has launched a number of global and regional initiatives. More than 200 transboundary aquifers have been identified. Inventories undertaken in the Americas, Asia, Africa, South-Eastern Europe, Central Asia and Caucasus, and Middle East have been already published separately. This Atlas presents a compilation of available data.

In recent years water security for people and the natural environment have taken a centre stage in much of the dialogue on international policy. Coordination among countries is essential for the sustainable management of transboundary aquifers. This atlas is intended to be a valuable reference that will encourage the sound and sustainable management of transboundary aquifers.
