Water resources in the Aral Sea Basin

Major trans-boundary rivers in the region – and the most important water sources for the Aral Sea Basin – the Amudarya and the Syrdarya, are at the centre of the disputes. The Amudarya, the biggest river in Central Asia in terms of water availability, is formed by the Panj River in Afghanistan and the Vakhsh River in Tajikistan, continues into Uzbekistan and Turkmenistan and ultimately into Uzbekistan, before emptying into the Aral Sea. The Syrdarya, the longest river in Central Asia, with a length of 3 019 km, has its source in the Tien Shan Mountains in Kyrgyzstan and flows westward toward Uzbekistan through the Fergana Valley, continuing into Tajikistan before it re-enters Uzbekistan and ultimately empties into the Aral Sea.
