Research

Hydropower decisions — where to build, how to operate, when to modernize, when to stop — are increasingly shaped by science. Environmental impact assessments, greenhouse gas emission models, river ecosystem studies, climate projections, and social impact analyses all feed into the policy and investment choices that determine what gets built and what gets blocked.

The Research section translates that science into analysis that practitioners can use. Every article in this section is grounded in peer-reviewed research, reports from international scientific institutions, or original data analysis — and every article connects its findings to the specific rivers, projects, and policy debates of the post-Soviet region.

We cover the science of hydropower’s environmental footprint: how reservoirs generate greenhouse gas emissions that vary dramatically depending on location, depth, and surrounding land cover; how changes in river flow regimes affect fish populations, sediment transport, and downstream agriculture; how climate change is already altering the hydrology on which existing plants depend — and what that means for planned capacity in the Pamir, the Tian Shan, and the Caucasus ranges.

We cover the science of planning and governance: what strategic basin-level planning can achieve compared to project-by-project approvals; how emission models change which dams look like good investments; what the global evidence says about resettlement outcomes, benefit-sharing mechanisms, and the long-term economic performance of large hydropower projects.

And we cover the gaps: where research on post-Soviet hydropower is thin, where Soviet-era data remains underused by international science, and where the region’s rivers represent an underexplored frontier for freshwater ecology and climate research.

The Research section is not a journal digest. It is not a summary of whatever was published last month. It is a curated, editorially driven effort to bring the best available evidence to bear on decisions being made right now — about Rogun, about Kambarata-1, about the Dniester, about the dozens of small hydropower projects being planned across Kyrgyzstan and Kazakhstan. If a study tells us something important about how to build better or govern smarter in this region, we will cover it. If it does not, we will not.
