Toktogul Reservoir

Kazakhstan, Kyrgyzstan, Uzbekistan Agree on Toktogul Water Releases

Energy and water ministers from Kazakhstan, Kyrgyzstan, and Uzbekistan signed a trilateral protocol in Tashkent on May 7 establishing agreed water release volumes and schedules from the Toktogul Reservoir for the next two months. The Toktogul Reservoir plays a central role in maintaining water and energy stability across Central Asia. The Toktogul Hydropower Plant, located on the Naryn River, the main tributary of the Syr Darya, is Kyrgyzstan’s largest power station and supplies around 40% of the country’s electricity. The reservoir serves a dual purpose: generating electricity for Kyrgyzstan while regulating water flows essential for downstream agriculture in Kazakhstan and Uzbekistan. During winter, Kyrgyzstan typically increases electricity generation to meet heating demand, often lowering reservoir levels and reducing the amount of water available for irrigation during the following spring and summer. According to Kazakhstan’s Energy Ministry, the newly signed protocol removes uncertainty for farmers in southern Kazakhstan at the start of the agricultural season and allows both Kazakh and Uzbek farmers to begin irrigation activities on schedule. To ensure stable water supplies throughout the remainder of the growing season, the three countries agreed to continue coordination in stages. The next ministerial meeting is scheduled for mid-June in Bishkek, where officials plan to finalize water release schedules for the critical summer months of July, August, and September. The agreement highlights the continued functioning of the region’s interstate water-energy exchange mechanism. Coordination over summer irrigation flows was preceded by extensive cooperation during the winter season. From September 2025 to April 2026, Kazakhstan supplied more than 1.5 billion kilowatt-hours of electricity to Kyrgyzstan, helping the upstream country reduce winter water releases for heating and preserve additional reserves in the Toktogul Reservoir for summer irrigation needs in Kazakhstan and Uzbekistan. According to Kyrgyzstan’s Deputy Energy Minister Altynbek Rysbekov, the Toktogul Reservoir held 7 billion cubic meters of water on April 1, 2026, down from 9.14 billion cubic meters on January 1 after the winter heating season. The reservoir’s so-called “dead water level,” the threshold below which turbines can no longer operate, stands at 6.5 billion cubic meters.

UNEP Interview: From Space, Central Asia’s Methane Challenge Comes Into Focus

Satellites are changing the way the world sees methane. What was once an invisible leak from a well, flare, pipeline, landfill, or coal mine can now be detected from space, traced to a specific site, and sent to governments and companies for action. A new analysis by the United Nations Environment Programme’s International Methane Emissions Observatory puts that system to the test. Its Methane Alert and Response System, known as MARS, uses 35 satellite instruments to identify major human-caused methane “super-emitters” and notify those responsible. UNEP says the system has already enabled 41 mitigation cases in 11 countries, covering sources estimated to have released 1.2 million tonnes of methane. For Central Asia, the findings are especially relevant. UNEP’s new data includes a rolling list of the world’s 50 largest satellite-detected methane sources, covering oil and gas, coal, and waste, and shows where rapid action may be possible. Several of those sources are linked to Turkmenistan’s oil and gas sector, placing the region firmly inside a global debate over methane transparency, climate responsibility, and whether satellite alerts can lead to action on the ground. Of the 50 sources featured in the latest UNEP/IMEO snapshot, China has the largest number, while Turkmenistan stands out sharply for Central Asia, with the second-largest individual source and four of the top ten. Methane is shorter-lived than carbon dioxide, but far more powerful in the near term. That makes cutting large leaks one of the fastest ways to slow global warming. The harder question, as UNEP’s latest data makes clear, is no longer only where the leaks are, but who responds when they are found. On April 30, UNEP/IMEO presented the new MARS findings, highlighting the growing role of satellite-based monitoring in identifying major methane sources and pressing governments and companies to act. The Times of Central Asia spoke with Meghan Demeter, MARS Programme Manager, International Methane Emissions Observatory, UNEP. TCA: What does the new MARS data reveal about Central Asia specifically that may surprise readers? Demeter: The latest MARS data products depict the region as one with growing engagement and significant mitigation potential. Responses to MARS notifications are increasing, supported in particular by designated national focal points who play a key role in coordinating follow-up with operators. Based on the published 2025 data alone, the response rate across Central Asia currently stands at 22%. Managing a high volume of alerts requires more effort to achieve very high response rates compared to countries that receive only a handful of notifications. Encouragingly, the region has already recorded nearly 20 mitigation cases, underscoring the strong potential for emissions reductions when large methane sources are identified and addressed. TCA: Why does Central Asia matter in the global methane debate, even if it is not the world’s largest methane-emitting region? Demeter: Across Central Asia, looking at the 2025 data alone, UNEP’s International Methane Emissions Observatory, through the Methane Alert and Response System (MARS), detected and notified 298 emission sources from the oil and gas sector. While satellites detect only a fraction of global methane emissions, satellites are highly effective at identifying so-called “super-emitters,” methane emission events so large they can be detected from space. These represent opportunities where action can deliver the greatest and fastest climate wins, while also catalyzing broader change. Regarding the “top 50” list of emission events, 11 of these sources are located in Central Asia, all from...

Regional Ecological Summit

Opinion: The Regional Ecological Summit and the Making of a Central Asian Voice

On 22–24 April, Astana hosted the Regional Ecological Summit—a gathering of governments, international organizations, financial institutions, and civil society that marked a new level of ambition in Central Asia’s environmental diplomacy. Fifty-eight sessions were held across three days at a moment when Central Asia’s ecological agenda is becoming inseparable from its political and economic future. The opening ceremony was attended by the presidents of all five Central Asian states. The summit adopted the Astana Declaration on Ecological Solidarity in Central Asia and brought renewed attention to the need to reform the International Fund for Saving the Aral Sea (IFAS). Taken together, these developments signal more than procedural diplomacy. They point to growing political momentum. The region has never lacked shared history or channels of communication. Russian remains a practical language of intergovernmental exchange, and borders, economies, rivers, energy systems, and labor markets have tied these countries together long before contemporary climate diplomacy gave this interdependence a new vocabulary. For decades, much external analysis of Central Asia expected this interdependence to produce confrontation, particularly around water and energy. Those risks remain real. Yet the Astana summit showed a more complex trajectory. Climate change, biodiversity loss, water insecurity, land degradation, and food security are not separate national problems neatly contained within borders. Addressing them is becoming one of the fields through which regional coherence is being built. The significance of the Summit lies less in ceremonial language than in the consolidation of multiple ecological agendas into a visible diplomatic architecture. Through its panels and high-level discussions, the Summit placed Central Asia’s natural heritage not at the margins of development but at its center. Ecosystems, rivers, glaciers, mountains, and landscapes are not only environmental assets. They are conditions for prosperity, stability, and resilience. Kazakhstan’s chairmanship of IFAS reopened the question of whether the Fund, long criticized for its limitations, can be reworked rather than left as a symbol of failed regional environmental governance. Kazakhstan’s proposal for an International Water Organization should be read in the same frame: it is not merely a technical proposal about water governance but an attempt to move a Central Asian concern into the language of global institutional reform. Kyrgyzstan’s mountain agenda and Tajikistan’s glacier diplomacy also belong to this broader pattern. They are not just isolated national branding exercises. Together with Uzbekistan’s increasingly active regional posture, they form a wider mosaic: each country brings a distinct ecological priority, but these priorities are becoming legible as parts of one regional perspective, and its voice carries more weight when presented as such. This is particularly important in the current geopolitical moment. As larger powers turn inward, compete over corridors, or speak about Central Asia through the old grammar of influence, the region is attempting to define itself not as terrain for another “Great Game" but as a pole of its own. This does not mean distance from external partners. On the contrary, the United Nations was a strategic partner of the Summit, and many formats involved major international organizations, European...

Uzbekistan and China to Develop Early Warning Systems for Dust Storms

Uzbekistan and China have agreed to expand cooperation on environmental protection, including the development of early warning systems for dust and sandstorms, according to Uzbekistan’s National Committee on Ecology and Climate Change. The agreement was discussed during a meeting between Aziz Abdukhakimov, Advisor to the President of Uzbekistan on environmental issues, and Huang Runqiu, China’s Minister of Ecology and Environment. The talks took place on the sidelines of a regional environmental summit. Both sides noted that cooperation between the two countries in environmental protection has been expanding and becoming more practical. Officials focused on joint efforts to address environmental challenges, introduce modern technologies, and strengthen scientific collaboration. Uzbekistan expressed appreciation for China’s support in establishing the Central Asian Regional Research Center for Combating Desertification and Developing Desert Economies at Green University, created with the participation of the Chinese Academy of Sciences. The center is expected to serve as a platform for research, training, and the development of solutions to land degradation. According to Huang Runqiu, cooperation between the two countries has already produced concrete results. He noted that 11 waste-to-energy plants are currently being built in Uzbekistan by Chinese investors, reflecting what he described as “a high level of trust” and effective bilateral cooperation. The Uzbek side proposed several new areas for collaboration, including studying China’s use of satellite systems for climate monitoring, gaining experience in tracking dust and sandstorms, and exploring the work of China’s national environmental monitoring centers. Other proposals included organizing a joint international forum on ecology and establishing a shared laboratory to monitor air and water quality. China expressed support for these initiatives and confirmed its readiness to move toward practical implementation. The two sides discussed creating a joint laboratory for environmental monitoring and expanding scientific research, including cooperation with international organizations such as the World Meteorological Organization. A key outcome of the meeting was an agreement to apply China’s experience in early warning systems for dust and sandstorms in Uzbekistan. These systems are expected to improve preparedness and response to environmental risks. China also offered to send scientists and experts to Uzbekistan to support training and capacity building, while inviting Uzbek specialists to China for knowledge exchange.

Water Scarcity

Opinion: As Water Runs Short, Uzbekistan Faces New Migration Pressure

In the 21st century, Uzbekistan is no longer just confronting an ecological crisis - it is on the verge of socio-political transformations driven by water. As agricultural lands are being degraded and river flows are decreasing, the country is now facing what experts describe as a “slow-onset disaster”: internal climate migration. The roots of this crisis go back to the tragedy of the Aral Sea, once the world’s fourth-largest lake, which has shrunk to roughly 10% of its original area since the 1960s largely due to Soviet-era irrigation projects. The human toll has been enormous: not only is agriculture in decline, but the lives of the people living in the Aral Sea region have been profoundly altered. Each year, storms lift an estimated 15 million to 75 million tons of sand, dust, and salt from the dried Aral seabed, spreading it across Uzbekistan and the wider region. Now, another challenge is looming - the water supply. In 2018, 79,942 internally displaced people were reported in Uzbekistan. The dwindling water supply and the threat to agro-ecosystems are creating a new generation of climate migrants. The number of climate-related displacements is expected to reach 200,000 in the coming years. The Amu Darya and Syr Darya rivers, Uzbekistan’s hydrological lifelines, are under growing strain from climate change, inefficient irrigation, and transboundary water-distribution pressures. Experts warn that the country's water deficit could reach 7 billion cubic meters by 2030, and 15 billion cubic meters by 2050. The World Bank predicts that Uzbekistan's economy could shrink by 10% by 2050 if no meaningful action is taken to adapt to climate change. Now, another new factor threatens to accelerate this trend. The Taliban government in Afghanistan is building the Qosh Tepa Canal, a 285-kilometer irrigation project that will divert water from the Amu Darya River. According to Rieks Bosch, an international expert on natural resources and economics, the canal will divert 20% of the Amu Darya's water, which will exacerbate water shortages in some parts of Uzbekistan and negatively affect agriculture. "In any case, Uzbekistan will definitely suffer," he said. Analyses show that up to 250,000 people could lose their jobs in agriculture as a result of water shortages. The most vulnerable regions - Bukhara, Khorezm, Karakalpakstan, Surkhandarya, and Kashkadarya - are located mainly in rural areas and depend on agriculture and livestock. With almost half of Uzbekistan’s population living outside urban centers, the loss of agricultural viability is not just an economic problem; it is the disruption of a way of life. “Water scarcity, air pollution, biodiversity loss, and a sharp decline in agricultural productivity are constantly increasing,” President Shavkat Mirziyoyev said at COP 28, acknowledging that these problems are “reaching their “critical peak.” Yet policy responses are still lagging behind the pace of environmental change. Uzbekistan’s climate migration problem cannot be solved by managing water resources alone. This requires a new strategic framework – a “Water-Migration-Security” strategy that combines regional cooperation, innovative water-saving technologies in agriculture, and proactive adaptation measures for the communities most at...

Regional Ecological Summit

Central Asia Seeks Solutions to Water Scarcity Amid Climate Risks

Central Asian countries must accelerate the transition from discussing climate goals to implementing them in practice, as water scarcity intensifies and the impacts of climate change deepen, participants at a regional conference said on Friday. A key event on the final day of the Regional Ecological Summit (RES 2026) in Astana was the Central Asian Climate Change Conference (CACCC), where government officials, international organizations, and experts discussed risks to the region’s water, energy, and food security. Participants noted that declining water availability requires a fundamental shift in resource management approaches. [caption id="attachment_47800" align="aligncenter" width="1280"] Image: TCA[/caption] “In conditions of reduced water availability, the priority is no longer increasing water intake but improving efficiency in water use. Today, government support for water-saving technologies covers up to 80% of costs. This represents a fundamental shift toward rational and economically sound water management,” said Kazakhstan’s Vice Minister of Water Resources and Irrigation, Talgat Momyshev. According to him, by 2030, the use of such technologies is expected to expand to more than 1.3 million hectares, potentially reducing agricultural water consumption by approximately 30%. “This is not just about saving resources, but about forming a new management model where data, forecasting, and cross-sectoral coordination play a central role,” he added. Kazakhstan is also developing a national water information system that will integrate data on surface and groundwater resources. More than 6,000 canals are expected to be digitized by the end of the year, enabling a shift toward predictive water management. Participants placed particular emphasis on the transboundary nature of water resources in the region. [caption id="attachment_47801" align="aligncenter" width="1280"] Image: TCA[/caption] “The development of joint monitoring systems and data exchange, the creation of resilient infrastructure, and the coordination of water and energy policies are becoming increasingly important. We believe that data, trust, and joint planning must form the foundation of effective climate adaptation,” Momyshev said. International partners confirmed their readiness to expand support for the region. “Our current efforts in the water sector are reflected in the Swiss Cooperation Programme for Central Asia for 2026-2029," said Tobias Werder, a representative of the Swiss government. "More than half of its $200 million budget is allocated to water-related projects. Since 2017, we have also actively promoted the Blue Peace Central Asia initiative, which helps strengthen regional coordination and move from dialogue to practical solutions.” Kazakhstan’s Minister of Ecology and Natural Resources, Yerlan Nyssanbayev, noted that the climate agenda in the region extends far beyond environmental issues. “For Central Asia, climate change is no longer a distant projection. It is a factor directly affecting water, energy, agriculture, infrastructure, and public health. Under these conditions, the climate agenda becomes a matter of economic resilience, regional security, and the quality of public governance,” he said. [caption id="attachment_47799" align="aligncenter" width="1280"] Image: TCA[/caption] According to Nyssanbayev, the region must accelerate the implementation of concrete projects. “It is now clear that we must focus on improving project preparation, expanding access to climate finance, and strengthening coordination. Without this, achieving our stated goals will be...
