Central Asia Agrees New Water Limits, but National Quotas Remain Unclear

Water has repeatedly caused friction between Central Asian governments. Uncoordinated releases have flooded communities downstream, while disputes over access have contributed to deadly fighting along contested borders. On October 7, the region's countries agreed on water withdrawals from the Amu Darya and Syr Darya for fall and winter 2026–2027, though published results do not reveal how much water each country will receive. The agreements were reached at the 95th meeting of the Interstate Commission for Water Coordination (ICWC) in Avaza, on Turkmenistan's Caspian coast near Turkmenbashi. Participants agreed on national water withdrawal limits and projected reservoir operating schedules, but the figures remain in unpublished annexes to the meeting protocol. Regional cooperation has grown in recent years. In June, Kazakhstan, Kyrgyzstan, and Uzbekistan agreed on water releases and electricity supplies for the 2026 irrigation season, continuing efforts to coordinate reservoir operations across borders. Despite this progress, longstanding tensions remain. Kyrgyzstan and Tajikistan need water in the winter to generate electricity, while Kazakhstan, Uzbekistan, and Turkmenistan need it in the summer for irrigation. Bishkek has revived proposals for its neighbors to share the costs of maintaining reservoirs, while Afghanistan's Qosh Tepa Canal could put further pressure on the Amu Darya. Countries are also trying to resolve discrepancies in river-flow measurements.

Kyrgyzstan's Toktogul Reservoir sits on the Naryn River, the Syr Darya's main tributary. In winter, Kyrgyzstan releases water to generate electricity, months before downstream farmers need it for irrigation. When these releases exceed the capacity of reservoirs and canals, the excess water can cause flooding. In February 2004, residents of Kazakhstan's Kyzylorda region experienced the consequences of uncoordinated water releases. The Syr Darya overflowed its banks, forcing the evacuation of at least 200 families. Ice had already restricted the river's flow, worsening the flooding. According to NASA, Kyrgyzstan was releasing more water from its hydropower system than the agreements allowed, with the excess flow entering the Shardara Reservoir. Uzbekistan agreed to divert some of the water into the Arnasay lake system, but it was not possible to divert the entire volume needed. As a result, the river flooded areas farther downstream. In the Amu Darya basin, disagreements developed differently. In 2012, then-Uzbek President Islam Karimov warned that disputes over water resources could lead to war. The source of tension was the construction of the Rogun Hydropower Plant in Tajikistan. Tashkent feared that a large dam on the Vakhsh River, a tributary of the Amu Darya, would allow Dushanbe to influence the volume of water reaching Uzbekistan's agricultural regions. The confrontation was accompanied by interruptions in gas supplies to Tajikistan, transport restrictions, and mutual accusations. Dushanbe linked Tashkent's actions to pressure over the Rogun project, although the Uzbek side disputed that...

Afghanistan’s Qosh Tepa Canal Raises Water Security Fears

Water has long been one of Central Asia’s most contested resources, shaping agriculture, energy policy, and diplomacy across the region. Recently, Afghanistan’s Qosh Tepa Canal project has emerged as a central point in this debate. Promoted by the Taliban as a vital step toward achieving food security and economic growth, the canal also raises alarm bells among downstream neighbors who heavily depend on the Amu Darya River. Now, according to Islamic Emirate spokesman Zabihullah Mujahid, the second phase of the project is expected to be completed within five months, raising further concerns among downstream countries about its potential impact on regional water security. Progress on the Ground In August, the Afghan authorities stated that 93% of the second phase had been completed. Videos show the canal lined with concrete and stone in some sections, alongside the construction of large and medium-sized bridges to link surrounding settlements. The project spans 128 kilometers from Dawlatabad district in Balkh province to Andkhoy district in Faryab province and involves over 60 contractors, making it one of Afghanistan’s largest infrastructure projects. Origins and International Support The canal’s roots trace back to earlier international efforts. While some sources attribute its conceptual origins to Soviet or British engineers in the 1960s, significant development began in 2018 under President Ashraf Ghani. The project was supported by the U.S. Agency for International Development (USAID) and Indian engineering firms. According to the Scientific-Information Center of the Interstate Commission for Water Coordination (SIC ICWC), a $3.6 million feasibility study was launched in Kabul in December 2018, funded by USAID and conducted by AACS Consulting and BETS Consulting Services Ltd. The study was coordinated with several Afghan ministries, but has not been published. Following the Taliban’s takeover, the Islamic Emirate held an official inauguration ceremony on March 30, 2022. The full canal is designed to stretch 285 kilometers, measuring 100 meters wide and 8.5 meters deep, and is expected to divert an estimated six to ten cubic kilometers of water annually from the Amu Darya. Afghan media have quoted water management expert Najibullah Sadid, who projected the canal could generate between $470 million and $550 million in annual revenue. Regional Concerns and Environmental Risks The project has raised alarm in Uzbekistan, Turkmenistan, and Tajikistan, countries that depend heavily on the Amu Darya for irrigation. Experts at SIC ICWC point out that no environmental impact assessment was conducted for downstream states, nor were they formally notified of the construction, as required by international water conventions. In December 2022, Uzbek President Shavkat Mirziyoyev called for practical dialogue with Afghanistan and the international community to strengthen regional water security. Adroit Associates estimates that the canal could eventually divert up to 13 billion cubic meters annually, nearly one-quarter of the Amu Darya’s average flow. Environmental risks are also mounting. Analysts warn that Uzbekistan, which relies heavily on the river for agriculture, could face soil degradation and declining crop yields. Turkmenistan, where agriculture accounts for 12% of GDP, may also suffer severe disruptions. Some studies suggest Uzbekistan and...
