Water in Central Asia: Can the Five States Reach an Agreement?
Central Asia is entering a period of growing water stress, as climate change makes supplies less predictable while demand continues to rise. Populations are growing, economies require new energy and industrial capacity, glaciers are shrinking, and agriculture continues to consume most of the available water. The region’s two main rivers – the Amu Darya and Syr Darya – cross national borders, making it impossible for any one country to solve the problem on its own. After decades of disputes, Central Asian states are increasingly trying to manage water jointly. In 2026, that cooperation has produced further practical steps, from plans for automated water accounting in the Syr Darya basin to new proposals for reforming regional mechanisms. The question now is whether the five countries can agree on rules when their water needs remain different. Water and Energy: An Old Conflict The structural conflict is rooted in the region’s geography. Kyrgyzstan and Tajikistan are upstream states and use water in part for hydropower generation, particularly in winter. Kazakhstan, Uzbekistan, and Turkmenistan are downstream and need large volumes in summer during the irrigation season. During the Soviet period, a centralized exchange system was in place: upstream republics stored water in winter and released it in summer, receiving energy resources in return. After the collapse of the Soviet Union, that unified mechanism disappeared. Interstate agreements preserved a degree of coordination but did not eliminate the tension between upstream energy needs and downstream agricultural interests. Climate change is now adding another layer to the problem. Retreating glaciers in the Pamir and Tien Shan mountains are altering the timing and reliability of river flows, while populations and consumption are increasing. Countries across the region are planning new power plants, industrial facilities, mining projects, and data centers, while agriculture remains the largest consumer of water. From Seasonal Quotas to Joint Management The main formal mechanism for coordinating river allocations remains the Interstate Commission for Water Coordination of Central Asia (ICWC), established in 1992. Through it, countries coordinate water withdrawal limits and reservoir operating regimes in the Amu Darya and Syr Darya basins. In late 2025, the countries agreed on water allocations for 2026: for the Amu Darya, the total withdrawal limit for the water-management year from October 2025 to October 2026 was around 55.4 billion cubic meters, while the Syr Darya allocation for the non-growing season was approximately 4.2 billion cubic meters. The five-state framework does not, however, cover every major user of the Amu Darya. Afghanistan is outside the regional allocation system, while its Qosh Tepa Canal, now under construction, has added another source of uncertainty over future downstream flows. Such agreements keep the shared system functioning, but many decisions are still made ahead of each new season. Climate change and rising demand require a longer-term model. In February of this year, Kazakhstan proposed developing a Central Asian Framework Convention on Water Use, while joint infrastructure projects, including Kyrgyzstan’s Kambarata-1 hydropower plant with the participation of Kazakhstan and Uzbekistan, are gradually adding shared economic interests...
