Abstract
Transboundary aquifer (TBA) is an aquifer system that exists in more than one state. As an important component of the groundwater system, proper management and rational utilization in trans-boundary aquifers are significantly important for promoting sustainable development and good-neighbor relationships. The Transboundary Aquifers will not implicate by the country’s political boundary as it follows the natural boundary lines. Within the frame work of the UNESCO's International Hydrological Programme (IHP-Ⅵ & Ⅶ) activities for the International Shared Aquifer Resource Management (ISARM), the inventory on TBA in Asia both preliminary and detail has accomplished. Those TBAs are classified in to two types: regional and local grade. A of Asian Transboundary Aquifers Map has advanced. The updated map provides the situation of the regional TBAs identify as the actual shape. Countries with the TBAs should strengthen cooperation for coordination and joint management of groundwater resources in order to achieve sustainable use.
