Kazakhstan Seeds Clouds as Kyrgyzstan Questions Regional Impact

A small aircraft climbed out of Turkestan airport on July 10 with hygroscopic salt flares fixed beneath its wings. Operated by the United Arab Emirates’ National Center of Meteorology, it was searching for a cloud suitable for seeding. Pilot Ahmed Aljaberi described the aircraft as “specifically equipped with a cloud-seeding flare system.” But no suitable cloud appeared during the mission. Cloud seeding can try to draw more rain from an existing cloud, but it cannot make one from clear air. Kazakhstan launched the project in Turkestan on May 16, targeting more than 911,000 hectares of arable land in the country’s leading cotton-belt. The government puts the potential economic benefit at up to 35 billion tenge, roughly $75 million a year. The partnership gives Kazakhstan access to decades of Emirati experience in weather modification. The UAE program dates to the late 1980s, and Emirati specialists are training Kazakh meteorologists, pilots, engineers, and other staff. Kazakhstan’s government describes the Turkestan operation as the first project of its scale in the region, though weather modification in Central Asia has a longer history. Kochkunbek Bakirov, a geographer at Kyrgyzstan’s National Academy of Sciences, has described Soviet-era research in the Karshi steppe, the Naryn basin, and over Issyk-Kul. Kazakhstan also trialed a different approach in Mangystau in 2021, using an ionization-based system promoted as a way to increase rainfall. Its developer claimed the equipment had begun to influence local moisture. The Mangystau system used ionization; the current program uses aircraft and hygroscopic salt flares. Before operations began, Kazhydromet analyzed data from 39 meteorological stations covering 2020 through 2024, selecting the Turkestan Region after studying atmospheric conditions and terrain. Flights only proceed when naturally formed cumulonimbus clouds with sufficient vertical development are present, with Kazhydromet monitoring satellite imagery, synoptic data, and cloud development before operations. The aircraft releases salt-based particles into suitable clouds. Kazakhstan’s Ecology Ministry lists sodium chloride, potassium chloride, and magnesium compounds among the reagents. In hygroscopic seeding, the particles encourage liquid droplets to collide and coalesce, which can improve precipitation efficiency in a suitable cloud. The cloud and its moisture must already exist. By July 13, crews had completed eleven operational flights, mainly over the Otyrar and Sozak districts. Officials were still analyzing the results of each operation; the number of flights does not show how much extra rain the project has produced. Kazakhstan’s launch materials cite a possible 10 to 20% increase in precipitation under favorable conditions. Results elsewhere vary widely. A 2024 review by the U.S. Government Accountability Office found estimates of 0 to 20% additional precipitation in the studies it examined. The GAO also found that effectiveness remains difficult to evaluate and that suitable clouds must be present. The evidence is much stronger for some cloud-seeding methods than for others. The World Meteorological Organization (WMO) says the strongest recent causal evidence comes from wintertime glaciogenic seeding of orographic clouds, while Kazakhstan is using hygroscopic salts in convective clouds. Their large natural variability creates a weak signal-to-noise problem, making the added...

Syr Darya River

Central Asian States Plan Automated Water Monitoring on the Syr Darya

Central Asian countries have agreed to prepare a plan for automated water monitoring on the Syr Darya, one of the region’s main transboundary rivers. The system is intended to provide the countries with more accurate data on water volumes and distribution across the basin, where irrigated agriculture in several countries depends on river flows. The cost of weak coordination across Central Asia is already measured in billions: the World Bank estimates the region’s annual economic losses at more than $4.5 billion. The agreement was reached on August 7 in Turkistan, Kazakhstan. A working group to prepare the plan is expected to be established by the end of September. The decision was made at a meeting of the Interstate Commission for Water Coordination, a regional mechanism for coordinating the use of shared water resources. The Syr Darya is formed in the Ferghana Valley by the confluence of the Naryn and Kara Darya rivers, flows through Uzbekistan, Tajikistan, and Kazakhstan, and ends in the North Aral Sea. The Naryn originates in Kyrgyzstan, meaning that management of the basin involves four countries. The Syr Darya supplies major agricultural areas, while a cascade of reservoirs and hydropower plants links the distribution of river flows with electricity generation. The countries’ interests have not always coincided. In the upper reaches of the basin, water is used for hydropower generation, while farther downstream demand peaks during the summer irrigation season. Accurate monitoring and timely data exchange help countries plan water withdrawals and reservoir operations during months with the highest demand. Kazakhstan and Uzbekistan are already developing part of the future system. The two countries are automating ten hydrological monitoring stations on the Syr Darya, five on each side of the border. Sensors are expected to record water flow and transmit the data online. At the meeting in Turkistan, the two sides agreed to accelerate efforts to secure grant financing and consider expanding the system to other parts of the basin. Kazakhstan already has experience with automated monitoring. On parts of its irrigation network, sensors remotely transmit data on water levels and pressure. Over the past decade, more than 800 kilometers of lined canals have also been rehabilitated in four regions, while irrigation system upgrades have covered more than 100,000 hectares of farmland. Uzbekistan is also seeking to reduce irrigation losses. Agriculture accounts for about 90% of the country’s water consumption. One project provides for the reconstruction of 259 kilometers of major canals and the installation of automated water-flow monitoring systems. The World Bank estimates the expected water savings at around 540 million cubic meters a year. The current season on the Kazakh section of the Syr Darya has so far been favorable. Since April 1, around three billion cubic meters of water have flowed into the Shardara Reservoir in southern Kazakhstan. This volume is higher than both last year’s figure and the long-term average. The region received additional funding for water projects in July. The World Bank allocated a $20 million grant to improve the management of...

World Bank Approves $20 Million Project to Boost Cross-Border Water Cooperation in Central Asia

The World Bank has announced a $20 million grant to strengthen transboundary water cooperation in Central Asia. The project is intended to improve management of the Amu Darya and Syr Darya basins as climate change, ageing infrastructure, and rising demand increase pressure on shared water resources. The funding, approved by the World Bank’s Board of Executive Directors, will support the Central Asia Water Efficiency Cooperation Project (CAWEC). It will be implemented by the Executive Committee of the International Fund for Saving the Aral Sea (EC IFAS). EC IFAS’s current procurement notice identifies Kazakhstan, Tajikistan, Turkmenistan, and Uzbekistan as the participating states. According to the World Bank, limited cooperation over shared water and energy resources costs the region more than $4.5 billion a year. The bank says fragmented reservoir operations, weak data sharing, and ageing infrastructure prevent countries from capturing gains that better regional coordination could provide. The project will strengthen regional institutions, modernize water accounting and information systems, and improve data sharing. By 2031, EC IFAS is expected to prepare feasibility studies, technical documents, and environmental assessments for up to six transboundary water infrastructure projects involving at least two countries. The $20 million grant will not finance the construction of those projects. The preparatory work is intended to help governments attract further investment for irrigation modernization, water conservation and storage, and coordinated management of shared rivers. It will also support digital systems and equipment for the Amu Darya and Syr Darya basins. Up to 100 staff members from regional water organizations will receive training. The World Bank estimates that around 40 million people will benefit directly or indirectly from improved regional water management. The International Fund for Saving the Aral Sea was established in 1993 by Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan to coordinate responses to the environmental and economic consequences of the Aral Sea disaster. The project concerns the Aral Sea basin’s two principal river systems. The Amu Darya is formed by headwaters rising mainly in the Pamirs and Hindu Kush and flows through or along Afghanistan, Tajikistan, Uzbekistan, and Turkmenistan. The Syr Darya is fed by Tien Shan headwaters and crosses Kyrgyzstan, Uzbekistan, Tajikistan, and Kazakhstan. Both rivers historically fed the Aral Sea. The grant arrives amid severe regional water stress. Central Asian governments agreed 2026 allocations from the Amu Darya and Syr Darya in November 2025, but low reservoir levels and reduced inflows continue to threaten irrigation and energy production. Kazakhstan is pursuing a parallel effort to restore the North Aral Sea, the section of the former inland sea fed by the Syr Darya. In a ministry statement, Water Resources and Irrigation Minister Nurzhan Nurzhigitov said an additional 1.2 billion cubic meters of water should be directed to the North Aral by the end of 2026. According to the ministry, 1.4 billion cubic meters have been delivered since October 1, 2025. The North Aral now contains 23.5 billion cubic meters of water, while salinity has fallen by about 10% from a year earlier. Fishermen caught 4,200 metric...

Kazakhstan Hydrogeologists Complete Six-Month USGS Groundwater Training

Kazakhstani hydrogeologists have completed a six-month online training program led by experts from the U.S. Geological Survey (USGS). The Department of Groundwater at Kazakhstan’s Ministry of Water Resources and Irrigation organized the seminars for specialists at Kazhydrogeology, the country’s National Hydrogeological Service. Staff from its branches also took part. The training covered current approaches to groundwater monitoring and assessment. Participants also studied groundwater modeling and water resource management, drawing on international practices in hydrogeology. The USGS awarded certificates to 20 participants from Kazhydrogeology and its branches. Employees from the ministry’s Department of Groundwater and the Department of Strategic Development received certificates of appreciation. Bolat Bekniyaz, chairman of Kazhydrogeology’s management board, thanked the USGS for supporting the professional development of Kazakhstani specialists in groundwater research and management. He said the ministry would continue working with international partners through exchanges of professional experience and joint training. The seminars were held under ongoing cooperation between the ministry and the USGS. In May, Kazakhstani specialists attended training in Boise, Idaho, on U.S. groundwater-monitoring systems and modeling methods. They also studied techniques for protecting groundwater sources. Groundwater is important to water security in Central Asia’s arid and semi-arid areas. UNESCO estimates that it accounts for 98% of the world’s unfrozen freshwater. The organization says groundwater in Central Asia remains under-researched and under-governed, while cross-border cooperation is limited. Kazakhstan is also developing a national water information system that will integrate data on surface water and groundwater. As The Times of Central Asia previously reported, it is intended to support predictive water management.

UN: Uzbekistan Makes Major Progress in Reducing Water Stress, but Challenges Remain

Uzbekistan has recorded one of the world’s fastest reductions in water stress in recent years, according to a new United Nations case study on the country’s water-management policies. The study points to efforts to conserve water, modernize irrigation, and expand regional cooperation. It also warns that Uzbekistan remains under pressure from climate change and rising water demand, while environmental damage linked to the Aral Sea disaster continues to affect the country. The study, prepared by UN-Water, examines how Uzbekistan managed to reduce water withdrawals while maintaining agricultural production and economic development. The report describes the country’s experience as particularly relevant for other water-stressed regions and countries seeking practical solutions to increasing pressure on freshwater resources. Water has long been one of Uzbekistan’s most strategic resources. Much of the country consists of arid and semi-arid landscapes, while agriculture remains heavily dependent on irrigation. The challenge has become even more urgent as climate change affects water availability across Central Asia. According to the UN report, Uzbekistan’s level of water stress increased steadily until 2017. Since then, the country has undertaken large-scale reforms aimed at reducing water consumption and introducing more efficient technologies. These efforts have produced measurable results. In 2017, Uzbekistan’s freshwater withdrawals reached 169% of its total renewable freshwater resources. By 2021, that figure had fallen to 122%. Although still above sustainable levels and considerably higher than the regional average of 69%, the reduction of 47 percentage points within four years represents one of the most significant improvements recorded globally under Sustainable Development Goal 6, which focuses on clean water and sanitation. Data cited by the report show that total freshwater withdrawals declined from 58.9 billion cubic meters in 2017 to 42.5 billion cubic meters in 2021. Most of the reduction came from agriculture, where irrigation withdrawals fell from 53.7 billion cubic meters to 38.5 billion cubic meters during the same period. The UN attributes much of this progress to strong political commitment. According to the report, water management has become a national priority supported at the highest levels of government. UN-Water notes that water-efficiency goals have been incorporated into several development programs. These include the 2017-2021 Action Strategy and the New Uzbekistan Development Strategy for 2022-2026. The goals also appear in the Uzbekistan-2030 strategy. Among the government’s targets are the introduction of water-saving technologies such as drip irrigation, sprinkler irrigation, and laser land leveling across all cultivated land by 2030. Authorities also aim to save up to 15 billion cubic meters of water annually, reduce irrigation losses by 25%, and fully digitize the management of 200,000 water intake points. The report identifies the expansion of water-saving technologies as one of the most important factors behind the country’s progress. Uzbekistan has combined financial incentives, soft loans, and subsidies with training programs for farmers and water specialists. According to UN-Water, this approach has helped reduce investment risks and encouraged wider adoption of modern irrigation systems. These measures are especially important because agriculture remains Uzbekistan’s largest water user. According to data from the...

Kyrgyzstan’s Water Compensation Push Tests Central Asian Unity

Central Asia’s water diplomacy is entering a contentious phase. Kyrgyzstan, where much of the region’s runoff is formed, is reviving calls for economic compensation from downstream users. Kazakhstan and Uzbekistan have rejected the idea, saying current agreements do not provide for payments for transboundary river water. The dispute comes as the region tries to maintain annual water-allocation deals while adapting agriculture to worsening scarcity and climate pressure. Water has long tied together the region’s upstream and downstream states. The 2021 and 2022 clashes on the Kyrgyz-Tajik border showed how disputes over land, border infrastructure, roads, security posts, and water access can escalate when local tensions are not contained. Yet political will alone does not guarantee agreements between countries. The Central Asian republics cooperate on water issues through two interstate bodies. One is the International Fund for Saving the Aral Sea, established in 1993 by all five Central Asian republics. Kyrgyzstan suspended its participation in IFAS in 2016, and now attends the fund’s meetings as an observer. The second body is the Interstate Commission for Water Coordination, whose meetings are held once a quarter. At its 93rd meeting in Bukhara in early April, the commission confirmed limits for water withdrawal from transboundary rivers, following decisions approved at the 92nd meeting in Dushanbe. For the Amu Darya, the 2026 water allocations set the total withdrawal limit for the water-management year from October 2025 to October 2026 at about 55.4 billion cubic meters. Of this, 15.9 billion cubic meters is allocated for the cold period, from October to April. Tajikistan has been allocated 9.8 billion cubic meters per year, while Turkmenistan and Uzbekistan each receive 22 billion. A significant part of the flow, 44 billion cubic meters, must pass through the adjusted section of the Kerki hydrological post, helping secure the lower reaches of the river. For the Syr Darya, the total water withdrawal limit for the non-growing season is 4.219 billion cubic meters. Kazakhstan will receive 460 million cubic meters through the Dustlik Canal, Kyrgyzstan 47 million, and Tajikistan 365 million, while the largest share will go to Uzbekistan, 3.347 billion cubic meters. The inherited framework is also facing pressure from outside the five-state system. Afghanistan’s Qosh-Tepa Canal, which is being advanced outside the Soviet-era allocation structure, has added uncertainty on the Amu Darya. The Central Asian republics also cooperate in bilateral and trilateral formats. In January, Kazakhstan-Uzbekistan joint working groups met in Turkestan. The sides reaffirmed water cooperation, agreed to continue repairs on the Dostyk canal, and planned automated hydrological posts on the Syr Darya. In May, Kazakhstan, Uzbekistan, and Tajikistan agreed on the operating regime of the Bahri-Tojik Reservoir for the summer of 2026. From June to August, the reservoir is to operate in a coordinated mode to supply irrigation water to farmers in the Maktaaral and Zhetysai districts of southern Kazakhstan. These agreements show that regional mechanisms still work, but experts continue to warn that climate pressure, data gaps, and uneven national interests could overwhelm existing formats. “Forecasting the...
