Japanese Investment Tackles Uzbekistan’s Aral Sea Crisis

Until recently, the rehabilitation center in Akmangit, a settlement in Karakalpakstan, relied on sewage trucks to remove wastewater. Although it receives about 3,500 patients with disabilities each year, the center had no sewer system. In March 2025, a Johkasou system, a compact Japanese unit that treats wastewater biologically, was installed at the center. The treated water can now be reused for irrigation instead of being hauled away. Similar systems were installed at a kindergarten and a specialized school. In their first four months of operation, the three units treated more than 16,400 cubic meters of wastewater. Although these installations are small relative to Karakalpakstan’s water and sanitation needs, they illustrate Japan’s approach in Uzbekistan’s Aral Sea region through local pilot projects tied to longer-term development programs. During an October 2025 visit, a United Nations Development Programme (UNDP) delegation and a representative of the Embassy of Japan in Uzbekistan saw residents using the program to introduce drip irrigation and expand small businesses. A smoked-fish producer in Samanbay employed 12 people. Since 2020, Japan has funded trials of water-saving and wastewater-treatment technologies in the region, supported climate-resilient agriculture, and introduced local business-development models. These projects draw less attention than Central Asia’s uranium, critical-mineral, energy, and transport deals. In Karakalpakstan, however, Japan has pursued influence through smaller projects intended to remain in place for years. Water and Agriculture Projects In September 2023, Japan provided $2 million for a UNDP program promoting climate-resilient agriculture in four districts of Karakalpakstan. By the program’s conclusion in 2025, more than 7,700 residents had gained access to clean drinking water. The Johkasou units were among the program’s most visible elements. Developed in Japan in the late 1940s amid sanitation problems, the decentralized systems offer an alternative where centralized sewer networks are impractical. Their treated water can be reused for irrigation. The program tested another Japanese technology on the dried Aral Sea bed. In 2024, UNDP planted 1,000 saxaul seedlings using a superabsorbent polymer (SAP) that retains moisture around plant roots. Saxaul, a desert shrub or small tree, helps stabilize sand and limit the spread of salt and dust from the former seabed. The 1,000 seedlings formed part of UNDP’s Green Aral Sea initiative. Between 2020 and March 2025, the program planted 823,000 trees across 658.2 hectares. In February 2026, Japan and UNDP launched a $4.6 million project scheduled to run through 2028. Its work includes irrigation rehabilitation, digital water monitoring, wastewater reuse, and desalination powered by renewable energy. More than 1,000 farmers and households are expected to benefit. Local Business Models Japan has paired these technologies with models for local economic development. One is the One Village, One Product Movement (OVOP), which began in Japan’s Oita Prefecture in 1979. Under the model, communities develop marketable products based on local resources and skills. In Karakalpakstan, OVOP has been applied to agriculture, handicrafts, and food processing, including the small businesses visited by the delegation in October 2025. Another Japanese approach is kaizen ("continuous improvement"). It seeks to improve production and...

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...

Tajikistan’s Electricity Losses Add Pressure to Water and Climate Agenda

Tajikistan’s aging power grid has become part of the country’s water and climate policy. The issue returned to the agenda of European Union-Tajikistan cooperation on July 3, when the two sides held a development cooperation meeting in Dushanbe. Energy and water were included in the Global Gateway agenda, while other talks addressed transport and energy infrastructure, the digital economy, water-resource management, and strategic raw materials. Tajikistan gets nearly 98% of its electricity from hydropower. That gives the country a low-carbon power mix, while tying electricity supply to river flows, snowmelt, reservoirs, and glacier change. Losses in the power system add pressure to that link. Each kilowatt-hour lost in transmission or distribution must still be generated. In Tajikistan, that usually means more water passing through hydropower plants or imported electricity when reservoir levels are low. The European Bank for Reconstruction and Development (EBRD) has focused on concessional funding for loss-reduction projects. After a May meeting between Energy Minister Daler Juma and Holger Wiefel, the EBRD’s head in Tajikistan, the energy ministry put the aim plainly: “The sides discussed attracting concessional financing for projects aimed at reducing electricity losses and improving the efficiency of the country’s energy system.” Officials also discussed private investment. Hydropower plants in the Zarafshan basin and solar plants were discussed as well. No new financing has been announced from those discussions. The immediate context is an existing EBRD- and EU-backed program for the distribution network. The Times of Central Asia previously reported in April that Tajikistan would receive nearly €49.6 million from the EBRD to reduce electricity losses. The package combines a €28 million loan with grants and technical assistance for work in nine branches of the distribution network in Sughd and Khatlon. First Deputy Finance Minister Yusuf Majidi said the project would reduce energy losses, replace worn-out infrastructure, install modern meters, and improve billing and revenue collection. The EBRD project file gives the total project cost as €43 million. It includes up to €28 million in EBRD financing and a €15 million EU co-investment grant through the Asia Pacific Investment Facility. The project targets automatic billing and metering systems in nine networks of the Bokhtar, Kulob, and Guliston branches of Shabakahoi Taqsimoti Barq. The bank says the project is aimed at reducing high inefficiency and technical losses in Tajikistan’s power distribution network. Distribution losses fell from 19.2% in 2024 to 15.6% in 2025. Even after that fall, more than 3.1 billion kWh were lost in 2025. Officials linked the reduction to smart meters and digital metering. President Emomali Rahmon put the issue in direct terms in a late 2023 parliamentary address. “Our electricity losses are about 4 billion kWh,” he said, adding: “If we prevent this, then there will be enough electricity for everyone.” That comment predates the 2025 improvement, but it still explains why loss reduction has become part of the environmental case for energy-sector financing. Cutting losses can free up electricity without new generation and reduce pressure on winter imports and hydropower reservoirs. Reuters reported...

Flood Forecasting

U.S. Companies to Help Kazakhstan Improve Snow Monitoring and Flood Forecasting

United States-based aviation technology firms Dynamic Aviation and Airborne Snow Observatories Inc. will work with Kazakhstan’s Ministry of Water Resources and Irrigation to improve snow monitoring, spring runoff forecasts, and early flood warnings, as the country seeks to avoid a repeat of the devastating floods of 2024. The cooperation program was discussed last week during talks between Kazakhstan’s Deputy Water Resources Minister Aslan Abdraimov and representatives of the two American companies, according to the ministry. The project will use aerial monitoring technologies to collect data from river basins, prepare cartographic materials and analytical reports, and integrate that information into Kazakhstan’s flood forecasting and modeling systems. The parties agreed on a phased rollout of the program. The first phase will focus on the Zhabai River basin, where high-precision snow measurements will be carried out using aviation-based technology. The collected data will be integrated into the ministry’s database to refine methodologies, train local specialists, and assess the feasibility of expanding the system to other parts of the country. Later stages will extend monitoring and forecasting to other priority river basins and regions, with the long-term goal of using the system nationwide to improve water management, lower flood risks, and help reservoir operators plan releases more accurately. “It is important for Kazakhstan to have not only up-to-date data but also a practical tool that enables early management decisions, reduces flood risks, and protects the population, infrastructure, and agriculture,” Abdraimov said. The initiative builds on Kazakhstan’s broader efforts to modernize flood management following the severe spring floods of 2024, when rapid snowmelt triggered large-scale flooding across western and northern regions of the country. As previously reported by The Times of Central Asia, Kazakhstan recently launched the Tasqyn flood forecasting and modeling system, which is integrated with the Global Flood Awareness System, an international flood warning network. The 2024 floods destroyed thousands of homes and forced nearly 100,000 people to evacuate, highlighting the vulnerability of Kazakhstan’s water management system to increasingly volatile climate conditions.

Tajikistan and ADB Discuss Modernization of Tajik Sea Reservoir

Tajikistan is planning a major modernization of the Tajik Sea reservoir, known until 2016 as the Kayrakkum Reservoir. The project is a strategic water initiative for the country and the wider Central Asian region. Prospects for the project were discussed during a meeting between Tajikistan’s officials and representatives of the Asian Development Bank (ADB) in Ulaanbaatar, according to the Tajik state news agency Khovar. According to Tajikistan’s Ministry of Energy and Water Resources, the talks involved Presidential Economic Adviser Ne’matullo Hikmatullozoda, Energy and Water Resources Minister Daler Juma, ADB Director General for Central and West Asia Leah Gutierrez, and Regional Head of Regional Cooperation and Integration Asad Aleem. The meeting focused on the “Efficient Management of Water Resources of the Bahri Tojik Reservoir” project. Hikmatullozoda described the initiative as one of Tajikistan’s key infrastructure priorities, aimed at adapting to climate change and addressing transboundary water challenges. The work would reinforce the reservoir’s protective dams to reduce flood risks and modernize its pumping stations. It also covers upgrades to irrigation, drainage, and collector systems, along with a digital monitoring system used to control and track water infrastructure. Officials said the project is expected to improve water resource management under changing climate conditions. It is also intended to make irrigation supplies more reliable and expand hydropower generation capacity. A preliminary feasibility study has already been prepared with ADB support. The Tajik Sea is located in Tajikistan’s Sughd Region on the Syr Darya River. The reservoir was created following the construction of a dam and hydropower station to regulate the river’s flow, with filling beginning in the 1950s. Today, the Tajik Sea remains one of the country’s largest reservoirs and an important site for energy production and irrigation. The adjacent Kayrakkum Hydropower Plant generates electricity, while the reservoir supplies water for agriculture across the region.

Rogun Dam

Inside Tajikistan’s Rogun Dam, the Mega-Project Built to Power a Nation

“Building a hydroelectric power plant is a responsibility for our country!” Displayed in Tajik at the entrance to the Rogun construction site, deep in the mountains of Tajikistan, the slogan captures the significance of what has become the most ambitious infrastructure project in the country’s history - and one of the largest hydropower developments in the world. Nearly fifty years after the Soviet authorities launched construction in 1976, the mega-project is finally entering a decisive phase. Long delayed by the collapse of the Soviet Union, the civil war of the 1990s, and the economic struggles of Central Asia’s poorest country, the project has gained renewed momentum over the past decade. After a two-hour drive through the mountains east of Dushanbe, the scale of the site gradually comes into view. Located more than 1,300 meters above sea level, Rogun is far more than a dam. The complex includes dozens of kilometers of tunnels, diversion canals, underground power stations, and an extensive network of technical infrastructure carved into the rock. [caption id="attachment_49947" align="aligncenter" width="1365"] Turbines in the process of being built[/caption] Once completed, according to current project plans, the structure will rise to 335 meters, making it the tallest dam in the world, Tajik officials proudly note. For now, it stands at approximately 140 meters. “This is where the Vakhsh River flows,” says Anvar Rahmonov, Production Director at Rogun HPP, standing on a ridge overlooking the future reservoir. [caption id="attachment_49948" align="aligncenter" width="2048"] Anvar Rahmonov, Production Director at Rogun HPP[/caption] Fed by glaciers in the Pamir Mountains, the river is diverted through underground galleries that currently power two 600-megawatt turbines. Below, dozens of trucks move continuously across the site while workers labor across different sections of the project. The deep blue waters of the future reservoir - designed to hold more than 13 billion cubic meters of water - contrast sharply with the surrounding red-earth mountains and the constant movement of heavy machinery. The project remains far from complete. Four additional turbines are still under construction. Once fully operational, the plant will have a total installed capacity of 3,600 megawatts, according to Tajik project officials, comparable to that of a nuclear power station. Ending Chronic Energy Shortages For a country of just over ten million people that continues to face electricity shortages every winter, the stakes are enormous. Despite possessing one of Central Asia’s largest hydropower potentials, Tajikistan still suffers from a chronic energy deficit. During the winter months, the country lacks roughly a quarter of the electricity needed to meet domestic demand, resulting in rationing and power restrictions across much of rural Tajikistan. “Thanks to this project, Tajikistan will be able to achieve energy independence,” says Andres Ricaldi, an engineer with the Franco-Belgian consultancy Tractebel, which is involved in the project. In the substation, a diagram of the power lines supplying the different regions is shown. [caption id="attachment_49946" align="aligncenter" width="2048"] Substation zone[/caption] Yet Rogun’s ambitions extend well beyond the domestic market. “The meaning of the Rogun Dam has changed,” explains Artemy Kalinovsky,...
