Asia's water resources are largely transnational, making inter-country cooperation and collaboration essential. Yet the vast majority of the 57 transnational river basins in continental Asia have no water-sharing arrangement or any other cooperative mechanism. This troubling reality has to be seen in the context of the strained political relations in several Asian sub-regions.
The river basins in the Asian continent that have a treaty-based sharing arrangement currently in place are the Al-Asi/Orontes (Lebanon-Syria), Araks-Atrek (Iran-Russia), El-Kaber (Lebanon-Syria), Euphrates (Iraq-Syria), Gandhak (India-Nepal), Ganges (Bangladesh-India), Indus (India-Pakistan), Jordan (Israel-Jordan), and Mahakali (India-Nepal).
Arrangements in some of these basins, such as the Gandhak, Jordan, and Mahakali, do not incorporate a formula dividing the shared waters between the parties but rather center on specific water withdrawals, transfers, or rights of utilization. An important arrangement in the Mekong Basin is centered on sustainable water management but without any water sharing.
