Environmental advocates have sharply criticized the World Bank’s decision to reject a request for a full investigation into Tajikistan’s Rogun Hydropower Plant, citing concerns over potentially severe environmental and social consequences for communities downstream along the Amu Darya river in Uzbekistan and Turkmenistan.

According to the international coalition Rivers without Boundaries, the World Bank’s Board of Executive Directors dismissed the complaint despite mounting evidence that the project could exacerbate water scarcity, degrade water quality, damage vulnerable ecosystems, and displace rural populations dependent on agriculture and access to clean water.

The complaint, filed earlier this year on behalf of affected communities, argued that the project’s environmental impact assessments were based on outdated data and non-binding verbal assurances from Tajikistan that the reservoir would not be operated at full capacity.

The World Bank’s Inspection Panel registered the complaint in April 2025 and, after conducting an initial review, including a fact-finding visit to Tajikistan in June, recommended a comprehensive investigation, citing a strong likelihood of harm. However, the Bank’s Board rejected that recommendation, asserting that only citizens of the country receiving Bank financing are eligible to request an investigation. This decision surprised observers, particularly given that the Bank had previously accepted similar complaints from Uzbekistan over the same project in 2010.

Environmental groups argue that the Board’s procedural reasoning allows it to ignore the project’s far-reaching transboundary impacts. Evgeny Simonov, a lead expert at Rivers without Boundaries, stated that the Inspection Panel’s own findings validated the downstream communities’ concerns. He accused the Bank of avoiding accountability by hiding behind technicalities.

Alexander Kolotov, director of the same coalition, said the ruling reveals a contradiction between the Bank’s public commitments to inclusive development and its actual response to cross-border grievances. He warned that dismissing downstream voices undermines the principles of equitable and participatory water governance.

Environmental experts also caution that the refusal to launch an investigation leaves no recourse for affected communities should their fears materialize. Potential long-term impacts include increased soil salinity, reduced agricultural productivity, and the erosion of traditional rural livelihoods.

The Rogun Alert coalition, an alliance of international environmental organizations, announced plans to continue monitoring the situation and to explore alternative mechanisms to protect the environmental rights of the region’s residents.

Previous assessments had warned that filling the Rogun reservoir could reduce water flows to the Amu Darya delta by 25% or more, with potentially devastating effects on ecosystems and the wellbeing of up to 10 million people in Uzbekistan and Turkmenistan.
