Aral Sea

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...

Land Degradation

Kazakh Environmental Group Proposes Trials of Chinese Land-Restoration Technologies

Around 29 million hectares of land in Kazakhstan are affected by erosion, while 27.1 million hectares of pastureland are degraded. Kazakhstan’s environmental association ECOJER is proposing trials of Chinese technologies to retain soil moisture, reduce pesticide use, and restore land in the country’s arid regions. ECOJER representatives studied these technologies during a visit to China’s Hunan province. The association was particularly interested in biological fertilizers, targeted spraying, specialized seed treatment, and methods for restoring pastureland. According to ECOJER, targeted spraying can reduce the use of chemical pesticides by 30-50%. For degraded pastures, Chinese specialists use bio-organic additives and ground-cover crops. These stabilize the topsoil and help retain moisture. According to data presented to the association, the soil’s moisture-retention capacity could increase by 20-30%. These figures have not yet been tested in Kazakhstan. Another area concerns carbon farming. ECOJER proposes creating a digital map of organic carbon content in the country’s soils and assessing the amount of CO₂ absorbed by agricultural land after soil conservation technologies are introduced. The association estimates the potential additional absorption at 15-30 million tonnes of CO₂ a year. There is currently no independent confirmation of this estimate. “For Kazakhstan, the key task is to model the carbon content of soils and assess their exact sequestration potential. This will make it possible to determine the environmental contribution of our land to decarbonization while also providing an economic benefit for farmers through additional returns from climate projects,” said ECOJER CEO Rustem Kabzhanov. Kazakhstan has already begun research in this area. In 2025, the KAZ AGRO CARBON agroclimatic carbon testing site opened in the Akmola region. Soil carbon content and greenhouse gas fluxes are measured at the site. Following the visit, ECOJER also proposed establishing a joint Chinese-Kazakh center for carbon farming. The center is intended to test drought-resistant varieties and soil restoration technologies. For now, the project remains at the proposal stage. The Times of Central Asia previously reported that ECOJER had been granted special consultative status with the United Nations Economic and Social Council, ECOSOC.

Samarkand’s Sher-Dor Madrasah Restoration Reaches First Milestone With U.S. Support

A major international effort to preserve one of Central Asia’s most iconic architectural monuments has reached a new milestone, with officials in Samarkand marking the completion of the first phase of restoration work on the façade of the Sher-Dor Madrasah, part of the historic Registan Square complex. According to a June 3 report from the Uzbekistan Art and Culture Development Foundation (ACDF), the ceremony was attended by Sarah Rogers, the United States under secretary of state for public diplomacy and public affairs, ACDF Chairperson Gayane Umerova, and U.S. Ambassador to Uzbekistan Jonathan Henick. The restoration project focuses on the conservation of the Sher-Dor Madrasah’s historic façade, including its mosaics, majolica decorations, ornamental elements, and Kufic inscriptions. The work forms part of a three-phase program supported by the U.S. Ambassadors Fund for Cultural Preservation (AFCP). During the event, ACDF and the U.S. Embassy in Uzbekistan also signed a five-year roadmap for cooperation aimed at expanding joint initiatives in cultural heritage preservation and cultural exchange. The project is one of the largest cultural heritage grants awarded to Uzbekistan by the U.S. government. According to the U.S. Embassy, the Cultural Heritage Agency of Uzbekistan secured a $500,000 AFCP grant after its proposal was selected through a global competition. The award was both the largest in that year’s competition and the largest AFCP grant ever received by Uzbekistan. The initiative is being implemented by the Cultural Heritage Agency with technical support from the International Institute for Central Asian Studies. Local craftsmen and restoration specialists are carrying out the work, while international experts are providing consultation and access to scientific documentation and conservation resources. During the ceremony in Samarkand, Henick and Umerova exchanged a letter of intent reaffirming their commitment to advancing the action plan and expanding bilateral cooperation in the field. Umerova, who is also head of the Department of Creative Economy and Tourism of the Administration of the President of Uzbekistan, said the project is about more than preserving a historic building. “We are grateful to the United States Embassy and the Ambassadors Fund for Cultural Preservation for their partnership and shared commitment to safeguarding cultural heritage. Together, we are preserving not only one of the world’s most remarkable architectural ensembles, but also the traditions and craftsmanship that give it meaning,” Umerova said. She noted that the Registan has served as a symbol of learning and cultural exchange for centuries and described the restoration project as an example of international cooperation built on mutual respect and a shared responsibility to protect cultural heritage. “We are thrilled to be part of the restoration efforts of the beautiful and iconic Sher-Dor Madrasah in the historic Registan Square,” Henick said. “These efforts will help preserve this important monument for many generations to come and for all humanity.” The Sher-Dor restoration forms part of a 2023 cultural property agreement between Uzbekistan and the U.S. The agreement created a framework for cooperation on protecting cultural heritage, including measures to combat the illicit trade in archaeological and ethnological material...
