Opinion: Water Without a Guarantor – Central Asia’s Next Security Test
The Fourth High-Level International Conference on the International Decade for Action, “Water for Sustainable Development,“ taking place in Dushanbe on May 25-28, comes at a difficult moment. Central Asia's water problem is no longer only about environmental management; it is moving into the field of regional security. The conference agenda is familiar and necessary: climate, investment, innovation, transboundary cooperation, and the implementation of the Water Action Decade. The harder question is what happens outside the conference hall. Does Central Asia still have a credible way to stop water stress from becoming an interstate crisis? For decades, the region operated in a post-Soviet setting in which Moscow shaped many security calculations, even though it was never a formal water arbiter. That setting has weakened. Russia has not disappeared from Central Asia, and it still retains military, economic, and institutional leverage. But since 2022, its role as the assumed external stabilizer has become less convincing. The result is not a simple vacuum. It is a more awkward reality: a region with many outside actors, but no trusted water-security guarantor. The Old Backdrop Is Weakening Central Asia's water system was built around a Soviet-era division of functions. Upstream republics, Tajikistan and Kyrgyzstan, controlled the mountains, reservoirs, and hydropower potential. Downstream republics, Uzbekistan, Kazakhstan, and Turkmenistan, depended on seasonal water flows for agriculture, food security, and social stability. The Soviet system managed those tensions through central planning. After independence, cooperation became more fragile. Water, energy, borders, electricity, and agriculture were separated into national strategies. The rivers, however, remained transboundary. For many years, Russia remained the largest external power around which regional security calculations were organized. That did not make Moscow an effective water manager, but it helped shape the political environment. Today, that environment has changed. The CSTO did not prevent the Kyrgyz-Tajik border escalations of recent years. Kyrgyzstan and Tajikistan eventually reached a border agreement through direct negotiation rather than outside enforcement. That difference is not academic. Water disputes are rarely settled by conferences alone. They need trusted channels for mediation, compensation, and restraint when pressure builds. Central Asia has plenty of statements about cooperation. It has fewer tools for managing coercion when water becomes scarce. Three Pressure Points The region's water-security stress is already visible in three places. The first is Afghanistan's Qosh-Tepa Canal. The canal draws water from the Amu Darya, a river system critical for Uzbekistan and Turkmenistan. Because Afghanistan was not part of the old Soviet water-allocation arrangements, the Taliban government is creating a new upstream reality outside the inherited regional framework. Estimates of the canal's downstream impact vary widely. Some analyses suggest it could divert between 15 and 30% of the Amu Darya's flow, depending on the completion timeline, irrigation efficiency, and water-management practices. The Times of Central Asia previously reported that reduced Amu Darya flows could indirectly affect Kazakhstan if Uzbekistan compensates by drawing more heavily on the Syr Darya. Carnegie has described the Qosh-Tepa as a serious test for regional water cooperation. The second pressure point...
