Aral Sea Restoration Could Prevent 605 Million Tons of CO2 Emissions

The drying of the Aral Sea has created another environmental problem: according to a study, exposed lakebed sediments released about 748 million tons of CO2 into the atmosphere between 1960 and 2022. Organic carbon remains stored in the sediments, and restoring part of the water cover could prevent the release of another 605 million tons of CO2. This gives efforts to restore the Aral Sea region a new climate dimension. The study, conducted by an international team of researchers led by scientists from Spain’s Centre for Advanced Studies of Blanes (CEAB-CSIC), was published in Science on July 16. The findings add another consideration to restoration efforts already underway across the region, from refilling part of the sea in Kazakhstan to planting saxaul and rehabilitating degraded land in Uzbekistan. The Aral Sea’s Carbon Legacy When the Aral Sea was still a fully-fledged body of water, plants and algae absorbed carbon dioxide, while some organic matter settled on the lakebed. As the water retreated, those sediments were exposed to the air, organic matter began to decompose, and the stored carbon started returning to the atmosphere as CO2. At the same time, winds carry salt and dust from the newly formed Aralkum Desert, spreading the consequences of the sea’s disappearance far beyond its former shoreline. In 2022, researchers conducted an expedition to the dried Aral Sea bed, collecting sediment samples and measuring how much CO2 was being released. Combined with satellite data, this allowed them to estimate carbon losses as the sea retreated. According to the researchers’ calculations, exposed sediments lost about 204 million tons of carbon between 1960 and 2022, equivalent to roughly 748 million tons of CO2. New vegetation growing on the dried lakebed has offset less than 1% of those emissions. A significant amount of organic carbon remains in the sediments. The researchers estimate that restoring water cover could prevent the release of another 605 million tons of CO2. The authors also considered the economics of such an effort. Using 2024 voluntary carbon market prices for land-use and forestry projects as a benchmark, they estimate that the avoided emissions could potentially be worth $3.6 billion to $18 billion in carbon credits. That money could theoretically become one source of funding for ecosystem restoration. Researchers estimate that about $9.7 billion in water-management improvements could increase inflows enough to restore roughly half of the area covered by the Aral Sea in 1960, while potentially generating about 323 million tons of CO2-equivalent carbon credits. Restoring the Entire Aral Sea Is No Longer the Goal Under current conditions, fully restoring the sea is widely considered unrealistic. The central issue is water. The Amu Darya and Syr Darya flow through several Central Asian countries. Significantly increasing the amount of water reaching the Aral Sea would be impossible without basin-wide agreements, irrigation modernization, and reductions in water losses. This is why restoration of the Aral Sea remains a regional issue rather than solely an Uzbek or Kazakh one. Central Asian countries coordinate part of this work...

Kazakhstan’s North Aral Recovery Anchors Broader Environmental Push

After decades in which the Aral Sea became a global symbol of ecological collapse, Kazakhstan has achieved a measurable recovery in its northern basin. Built over two decades, the turnaround is now being linked to expanded restoration plans and President Kassym-Jomart Tokayev’s broader Taza Kazakhstan, or “Clean Kazakhstan,” environmental agenda. According to the government, the North Aral’s volume rose from 18.9 billion cubic meters at the end of 2022 to 23 billion by the end of 2025. In July 2026, TCA reported that the Water Resources Ministry had put the volume at approximately 23.5 billion cubic meters. The recovery reflects work centered on the Kokaral Dam, completed in 2005, and management of the Syr Darya. The first phase raised water levels, reduced salinity, and helped restore fishing. Kazakhstan’s Water Resources Ministry and the World Bank have developed plans for a second phase of the restoration program. The proposed project calls for the reconstruction of the Kokaral Dam and aims to increase the sea’s volume to approximately 34 billion cubic meters and expand its surface area to around 3,900 square kilometers. The recovery described here is confined to the North Aral in Kazakhstan. The South Aral remains severely depleted, while further progress in the north depends on Syr Darya flows and cooperation with upstream states. An August 22 government review places the North Aral alongside waste management, reforestation, and environmental education under Taza Kazakhstan. Launched by Tokayev in April 2024 as a nationwide cleanup campaign, the initiative is increasingly being used as a framework for a broader environmental program. Waste Infrastructure Illegal dumping is the clearest area of reported progress. The number of identified dumping sites fell from approximately 8,600 in 2018 to 2,600 in 2026, according to the government. Satellite monitoring is being combined with public reporting through eGov Mobile and TazaQazBot. Public reports have been processed through the two services since 2024. Local authorities have been given responsibility for cleaning public areas, while penalties for illegal disposal have been strengthened. Because the 2018 baseline predates Taza Kazakhstan, the longer-term decline also reflects measures taken before the initiative. The share of municipal waste sorted or processed increased from 25.8% in 2024 to 30.6% in 2025, according to the government. Kazakhstan still faces a serious infrastructure deficit. At the end of 2024, only 20.4% of the country’s municipal waste landfills had the required documentation, while major sites in Astana and Zhezkazgan were at or beyond capacity. A 2023 plan called for 100 new landfills, but a December 2025 government update said only eight had been commissioned. The August 2026 review provided no newer landfill total, but said upgrades were planned for existing sites and additional waste sector projects were moving into operation. Large waste-processing and utilization facilities are also under development in Astana, Almaty, and the Zhambyl region. TCA has previously reported that headline processing rates do not show how much waste becomes reusable material. Only about 1.1% of municipal waste generated in 2024 was converted into secondary raw materials. The...

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...

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...

Kazakhstan’s Aral Geopark Under Review for UNESCO Global Status

Kazakhstan's Aral Geopark is undergoing an international assessment that could make it the country's first UNESCO Global Geopark, giving new visibility to a region long associated with the environmental collapse of the Aral Sea. Kyzylorda Region governor Murat Yergeshbayev met international experts José Brilha and Somayeh Saediyounesi, who are assessing whether the site meets UNESCO requirements, regional authorities said. The main evaluation mission will take place from July 6 to 13 and will examine the park's natural sites, infrastructure, management system, scientific potential, and efforts to preserve the region's heritage. Kazakhstan sent the official application for the Aral Geopark's inclusion in the UNESCO Global Geoparks Network to the organization's headquarters in November 2025. Four tourist and educational routes have also been prepared as part of the application process. UNESCO Global Geoparks are single, unified geographical areas where sites and landscapes of international geological significance are managed through a concept that combines protection, education, and sustainable development. According to UNESCO, the network currently includes 241 geoparks in 51 countries. For Kazakhstan, recognition would give the Aral region greater international visibility. The geopark is intended to preserve the region's geological, natural, historical, and cultural heritage while supporting research, tourism, and local economic development. The project is also part of wider efforts to restore the Aral region and broaden its economic base. Yergeshbayev said Kazakhstan is paying close attention at the national level to the area's recovery, including the development of the geopark as a scientific and natural site. The Aral Geopark covers a landscape shaped by the retreat of the sea. According to the geopark's official description, its sites include the Barsakelmes State Nature Reserve, the Akespe hot spring, the Zhaksykylysh salt deposits, Lake Kamystybas, mausoleums, and settlements on the former seabed. UNESCO recognition is not automatic. A territory must first operate as a geopark, prepare a full application through national structures, undergo document checks, and host a field evaluation. Recommendations are then reviewed by UNESCO bodies before a final decision by the organization's Executive Board. If approved, the Aral Geopark would become Kazakhstan's first internationally recognized global geopark. Regional authorities say the status would help raise tourist interest, expand scientific research, and improve living standards for local residents. As previously reported by The Times of Central Asia, President Kassym-Jomart Tokayev proposed in December 2025 creating a dedicated United Nations body to address global water management challenges, including the deteriorating ecological conditions of the Aral and Caspian seas. In January 2026, Prime Minister Olzhas Bektenov instructed ministries to accelerate the second phase of Kazakhstan's Northern Aral Sea restoration plan. The goal is to increase the sea's volume by around 10 to 11 billion cubic meters over the next four to five years.

Eco Expo Opens in Samarkand as Uzbekistan Pushes Green Investment

Eco Expo Central Asia 2026 opened on June 2 at the Expo Center of Silk Road Samarkand, placing Uzbekistan’s green economy plans before officials, lenders, companies, scientists, and environmental groups already gathered in the city. The exhibition is scheduled to run through June 4 and is being held alongside the Eighth Assembly of the Global Environment Facility, one of the main global forums for environmental finance. The timing gives Uzbekistan a rare week of attention on climate, water, biodiversity, and clean technology. The GEF Assembly runs from May 30 to June 6 in Samarkand. The GEF says its Assembly is its highest governing body, made up of 186 member countries, and meets once every four years. GEF Council meetings are scheduled from May 31 to June 3, before the formal Assembly sessions later in the week. Eco Expo has a more practical focus. Its exhibition sections include protected natural areas, clean technology, green construction, transport, and energy, sustainable agriculture, green finance and green cities, ecotourism, water-saving technologies, environmental education, artificial intelligence in ecology, and the Aral Sea region. The business program includes lectures, seminars, panels, and roundtables for registered visitors. Uzbekistan’s state news agency UzA has said that approximately 10,000 participants from Uzbekistan and abroad are expected. The exhibition will include more than 68 pavilions for environmental products, plus 20 pavilions for startup projects from Central Asian countries. Organizers also plan more than 50 forums, presentations, and discussion platforms on green energy, waste recycling, water resource management, and sustainable development. The exhibition - organized by Uzbekistan’s National Committee on Ecology and Climate Change with Business Congress Management - is designed to turn local environmental plans into fundable projects. Regions and districts across Uzbekistan have prepared proposals for donors and investors, covering climate adaptation, better use of natural resources, and practical steps to make local economies more resilient. For Uzbekistan, the meetings are a chance to move from broad pledges to project lists, budgets, and partners. Farms need more efficient irrigation; cities need cleaner transport and better waste systems; protected areas need long-term funding. The expo brings those needs into one room with development banks, UN agencies, foreign governments, and companies looking for green projects. The GEF meetings bring the process closer to the expo floor. The fund says it has provided more than $26 billion in financing over three decades, and has helped mobilize another $148 billion for country-led environmental projects. In Samarkand, the 71st GEF Council meeting opened ahead of the Assembly and Eco Expo. Its agenda includes biodiversity protection, sustainable infrastructure, renewable energy, energy storage, the GEF-9 programming strategy, and support for vulnerable countries. Uzbekistan already has a working portfolio with the GEF, which includes 13 projects worth $56 million and five more projects worth more than $30 million in the pipeline. The projects cover biodiversity, snow leopard protection, restoration of ecosystems in the Aral Sea region, climate resilience, land management, and waste management. The week arrives as Uzbekistan faces rising climate stress. The World Bank has described...
