Kazakhstan Urges Regional Cooperation to Save the Aral Sea

Kazakhstan has intensified its efforts to restore its portion of the former Aral Sea, calling on neighboring Central Asian states to increase their participation in regional environmental cooperation. Once the world’s fourth-largest lake, the Aral Sea has become a symbol of ecological catastrophe. Experts warn that international efforts remain inadequate. How the Sea Died Straddling the border between Kazakhstan and Uzbekistan, the Aral Sea began to shrink in the 1960s when large-scale irrigation projects diverted water from its two main tributaries, the Amu Darya and Syr Darya rivers, to support cotton production and agriculture. A growing regional population added further strain. By 1989, the sea had split into the Northern (Small) and Southern (Large) Aral Seas. In 2014, the eastern basin of the Southern Aral Sea dried up completely. Today, the Aralkum Desert occupies much of what was once open water. Kazakhstan has since focused on restoring the Northern Aral Sea. [caption id="attachment_37684" align="aligncenter" width="2560"] A ship stranded in the desert, Moynaq, Uzbekistan; image: TCA, Stephen M. Bland[/caption] The restoration of the Northern Aral Sea has already yielded visible environmental and social benefits. Rising water levels have lowered salinity, allowing several native fish species to return. Local fisheries, once thought lost, are now active again in communities such as Aralsk. According to the Ministry of Ecology, the annual fish catch in the North Aral has risen more than tenfold since the early 2000s, reviving local employment and boosting food security. Experts note that even small ecological gains have had a profound psychological impact on residents who once witnessed the sea’s disappearance. Call for Renewed Efforts On October 15, Kazakhstan called for expanded international cooperation to protect both the Aral and Caspian Seas. First Deputy Minister of Foreign Affairs, Yerzhan Ashikbayev, speaking at the International Astana Think Tank Forum-2025, emphasized Kazakhstan’s contribution to the global climate agenda. He noted that a regional climate summit, set to be held in Astana in 2026, would provide a platform for coordinated strategies and joint decision-making among Central Asian nations. “Astana also calls for increased international participation in solving environmental problems and preserving the water resources of the Aral and Caspian Seas,” Ashikbayev said. Earlier, on October 10, Prime Minister Olzhas Bektenov met with senior officials from Tajikistan, Uzbekistan, and Turkmenistan during the second meeting of the Board of the International Fund for Saving the Aral Sea (IFAS), chaired by Kazakhstan. The event highlighted the need for a united regional approach, noting that restoration of the Aral Sea can be achieved through collective action. Bektenov acknowledged the challenges of the recent growing season, but said regional cooperation had helped maintain a stable water regime in the basin. “Each country has its own national interests, and we are obliged to defend them and will always do so. But I am convinced that our common strategic, long-term priority is good neighborly relations. In solving everyday short-term tasks, we must not undermine long-term priorities. I think that we will take joint measures to ensure that issues are always...

Kyrgyzstan Offers Support to Tajikistan with Innovative Water-Saving Technology

Kyrgyzstan is offering a novel solution to Tajikistan’s mounting water scarcity and pasture degradation: the construction of artificial glaciers, or so-called “ice towers.” These structures store water during the winter and release it during the arid summer months, providing a lifeline for communities affected by climate change. Innovation Amid a Warming Climate The initiative was highlighted during the session “Activating Global Action to Enhance Glacier Resilience: Civil Society Experiences in Central Asia,” held as part of the recent International Conference on Glacier Conservation in Dushanbe. According to Anar Alymkulova, executive director of Kyrgyzstan’s Institute for Sustainable Development, artificial glaciers have proven effective in mitigating the effects of climate change and addressing water shortages. Since the first ice tower was constructed in 2022 in Jalal-Abad, the initiative has expanded significantly. Two more towers were added in 2023, and in 2024, seven were built in Batken region, collectively storing over 1.5 million cubic meters of ice during the winter. By the end of this year, four additional towers are planned in the Batken and Leylek districts. In total, approximately 30 such structures now operate across Kyrgyzstan. How Ice Towers Work The technology is simple yet effective. Water from springs is channeled via an underground pipeline, spanning several kilometers, to a vertical pipe up to 20 meters tall. During winter, water is sprayed from the pipe and freezes, forming an ice tower 30 to 50 meters high. In the spring and summer, the ice melts gradually, supplying water for people and livestock. Oleg Guchgeldiev, Kyrgyzstan's representative in the UN's Food and Agriculture Organization (FAO), noted that each ice tower costs between $3,000 and $4,000 and can store up to 50,000 cubic meters of water. This method offers a practical solution in remote, arid regions where traditional water sources have become unreliable. A Critical Issue for Tajikistan Sustainable water management is a growing concern in Tajikistan, where more than 1,000 glaciers have disappeared in the last 23 years. The country has lost about 20% of its glacier volume and 30% of its glacier area over the past five to six decades. According to UNEP projections, Central Asia could lose over half its glaciers by 2050, jeopardizing water security for more than 64 million people, particularly in rural and mountainous areas. In response, the Tajikistan's President Emomali Rahmon spearheaded a successful campaign at the UN General Assembly to declare 2025 the International Year of Glacier Conservation. The initiative culminated in a major conference from May 29 to 31 in Dushanbe, attracting over 2,500 delegates from 80 countries and numerous international organizations. A Scalable Regional Solution The Kyrgyz model of artificial glaciers presents a scalable solution for Tajikistan and potentially the broader Central Asian region. As glacier retreat accelerates and drought risks rise, such technologies could play a key role in national climate adaptation strategies. “Artificial glaciers are not only a way to store water, but also a tool for adapting to a changing climate,” experts at the Dushanbe conference emphasized. “They demonstrate how local communities...

Hope for the Northern Aral Sea as Restoration Efforts Continue

Between October 2024 and January 2025, one billion cubic meters of water will be directed to the Northern Aral Sea - 100 million cubic meters more than initially planned. Agreements with Central Asian countries will further increase this figure to 1.6 billion cubic meters by March. According to Kazakhstan’s Ministry of Water Resources and Irrigation, the current water volume in the Northern Aral Sea stands at 22.1 billion cubic meters, up from 18.9 billion cubic meters at the beginning of 2022. By the end of 2025, this volume is projected to reach 23.4 billion cubic meters. The reservoir’s surface area has also expanded, reaching 3,065 square kilometers - an increase of 111 square kilometers over the past two years. The rising water levels have had a positive impact on the ecosystem: salinity has decreased, the population of 22 fish species has recovered, and the annual fish catch has reached 8,000 tons. Meanwhile, a project to preserve the Kokaral Dam and restore the Syr Darya River delta is nearing completion. Reconstruction work on dams between Lake Karashalan and the Syr Darya, the construction of the Tauir protective dam, and the renovation of the Karashalan-1 canal have already been completed. By the end of the year, the reconstruction of the Kokaral Dam is expected to be finished, further reducing salinity and stabilizing water levels in the Northern Aral Sea. Efforts to improve water efficiency in Kazakhstan’s Kyzylorda region have also contributed to the sea’s recovery. The use of laser leveling technology on rice fields has saved 200 million cubic meters of water, which has been redirected to the Northern Aral. The leveling of 55,000 hectares of rice fields has also boosted crop yields, increasing harvests from 40-55 centners per hectare to 70-80 centners per hectare. To encourage the adoption of water-saving technologies, the government has raised subsidies for infrastructure installation from 50% to 80% and increased compensation for irrigation water to as much as 85%, depending on the tariff. Reforestation efforts in the Aral Sea basin are also ongoing. Between 2021 and 2024, 4.4 million seedlings were planted on the dried-up seabed of the Large Aral Sea, covering 475,000 hectares. In 2025, an additional 428,000 hectares will be greened, bringing the total afforested area to 1.1 million hectares. Kazakhstan assumed the chairmanship of the International Fund for Saving the Aral Sea (IFAS) on January 1, 2024. As part of its leadership, the IFAS Executive Committee has approved a 2024-2026 work plan, which includes approximately 40 initiatives across 10 priority areas.

Kazakhstan Secures 11 Billion Cubic Meters of Irrigation Water from Central Asian Neighbors

Kazakhstan will receive 11 billion cubic meters of irrigation water by April 2025 under an agreement reached in Dushanbe at a meeting of the Interstate Water Management Coordination Commission of Central Asia. The meeting brought together water management officials from Kazakhstan, Uzbekistan, Tajikistan, and Turkmenistan. Discussions focused on managing water resources in the Syr Darya and Amu Darya River basins. The allocated volume will flow into the Shardara Reservoir in Kazakhstan’s Turkestan region via the Syr Darya River. Of this total, 1.6 billion cubic meters will be directed to the Aral Sea to support its ecosystem. Kazakhstan’s Minister of Water Resources and Irrigation, Nurzhan Nurzhigitov, stated that the agreement will help the country secure sufficient irrigation water for the upcoming agricultural season while sustaining ecosystems in southern Kazakhstan. Nurzhigitov highlighted the stark contrast between the south and other parts of the country: “There are no large-scale floods in the south as there are in the west and north. In the summer, the demand for irrigation water is extremely high. That’s why we take a different approach to water management in the south, where water diplomacy is a priority. Through negotiations, we ensured an uninterrupted water supply to the region last year. We continue to resolve water distribution and transboundary water protection issues in cooperation with our Central Asian colleagues.” Kazakhstan’s agriculture, particularly in its arid southern regions, depends heavily on irrigation water from upstream Central Asian neighbors. As a result, regional water management remains a crucial factor in both economic and political relations among the countries of Central Asia.

Kazakhstan Prepares for Flood Season by Releasing Water from Reservoirs

Kazakhstan's Ministry of Water Resources and Irrigation (MWRI) has begun releasing water from key reservoirs across the country to prepare for the influx of meltwater expected during the spring thaw. This proactive measure follows the devastating floods of spring 2024, the worst in 80 years, which affected multiple regions and displaced over 120,000 people. By pre-emptively releasing water from reservoirs, Kazakhstan hopes to mitigate the impact of the spring flood season. This preparation underscores the importance of coordinated water management to protect communities, agriculture, and infrastructure from the devastating effects of extreme weather events. In early January, the MWRI held a meeting to discuss water management strategies for the upcoming flood season. Authorities have initiated controlled releases in reservoirs located in the west, east, north, and center of the country - regions hit hardest by last year’s flooding. These releases are designed to reduce water levels in preparation for spring meltwater. Astana Reservoir: Between December 20, 2024, and January 3, 2025, 5.06 million cubic meters of water were released, lowering the reservoir to 83% of its total capacity. By April 1, its volume will be further reduced to 73% (300 million cubic meters). Aktobe Reservoir: Currently holding 51 million cubic meters, this will be lowered to 47.32 million cubic meters by April. Bitik Reservoir (West Kazakhstan): Discharging at 8.3 cubic meters per second, its volume has been reduced to 34.45 million cubic meters. Bukhtarma Reservoir (East Kazakhstan): Now at 79% capacity, this will be reduced by another 8% by spring. Yntymak Reservoir (Karaganda Region): Of its current 69 million cubic meters, only 39 million cubic meters will remain to accommodate floodwaters. Kengir Reservoir (Ulytau Region): Reduced to 86% of capacity, it will be lowered by an additional 11%. Upper Tobolsk Reservoir (Kostanay Region): Holding 585.4 million cubic meters, its volume will be reduced to 61% (499.37 million cubic meters) by April. MWRI head Nurzhan Nurzhigitov emphasized the importance of strategic water management throughout the year. “In spring, it is critical not only to collect floodwaters in reservoirs but also to distribute them to lake systems, natural pastures, and meadows,” he said. Nurzhigitov urged regional authorities to plan for efficient water allocation, noting that during the previous irrigation period, farms received approximately 11 billion cubic meters of water. Efforts to restore and preserve both large and small reservoirs were also highlighted. Last spring’s historic floods inundated regions in northern, western, eastern, and central Kazakhstan for nearly two months. Over 120,000 people were evacuated, with rescue efforts involving multiple government agencies, including the Ministries of Emergency Situations, Defense, and Internal Affairs, as well as local authorities and volunteers. Despite extensive state aid, many citizens raised concerns about the allocation of resources, as previously reported by The Times of Central Asia.

Kazakhstan Receives Abundant Water in 2024

Kazakhstan’s Ministry of Water Resources and Irrigation has reported record water accumulation in the country’s reservoirs and lakes in 2024. This year, Kazakhstan’s reservoirs collected over 75 billion cubic meters of water, including more than 12 billion cubic meters of floodwater from unprecedented spring floods in the western and northern regions. These floods were triggered by rapid snowmelt, leading to significant increases in water availability. According to the Ministry, efficient floodwater distribution helped replenish reservoirs and direct excess water to rivers and lakes that have faced drying trends in recent years. Notable allocations include: Lake Balkhash: Received 15.4 billion cubic meters of water in 2024, a 4-billion-cubic-meter increase from 2023. Of this, 3.3 billion cubic meters came from floodwater. Located 175 miles northwest of Almaty, Balkhash is the largest lake in Kazakhstan and the fifteenth-largest in the world. Caspian Sea: Gained 17 billion cubic meters of water, addressing concerns over its declining water level. The Times of Central Asia previously reported concerns that the Caspian could lose up to 18 meters of water by the end of the century. Kapchagay Reservoir: For the first time in a decade, this reservoir in the Almaty region filled to 100% of its capacity, collecting over 18 billion cubic meters of water. The reservoir regulates the flow of the Ili River, which originates in China and flows into Lake Balkhash. North Aral Sea: Received approximately 2.5 billion cubic meters of water, 400 million cubic meters more than in 2023. This portion of the former Aral Sea is fed by the Syr Darya River and separated from the South Aral Sea in the late 1980s due to water diversion for agriculture. Kamysh-Samar Lakes: Located in the West Kazakhstan region, these lakes were replenished with 80 million cubic meters of floodwater. Minister of Water Resources and Irrigation Nurzhan Nurzhigitov emphasized the Ministry’s efforts to preserve and restore large and small water bodies across Kazakhstan. During the 2024 irrigation season, approximately 11 billion cubic meters of water were supplied to the country’s farms to support agricultural activities. The record water accumulation and successful flood management efforts underscore Kazakhstan’s commitment to sustainable water resource management.
