Ilya Trombitsky. To what extent do the Regulations for the operation of reservoirs of the Dniester Integrated Hydropower Complex (2022) takes into account the environmental needs of the river? The article analyses the real impacts of the Dniester Hydro Energo Complex to the Dniester River low stream ecosystem and in what scale the authors of this newly adopted technical document solves the issue of negative impacts. It is demonstrated that despite of long-term draft discussions the regulation has almost no provisions directed to soften the negative impacts. It is also noted that the format of negotiations on improving the management of water and related resources of the Dniester River is not equal today, and the interests of hydropower dominate over the interests of other stakeholders, and this applies not only to relations between the two riparian countries, but also to stakeholders within Ukraine. The loose of ecosystem services in the result of hydropower development should be taken into account. To improve the situation, such format of bilateral cooperation should be revised in favor of equality of riparian countries and interests of stakeholders.
