Connecting fish and people: Protection of Fish Biodiversity in Mountainous areas of Central Asia

Small-scale hydropower (SHP) is not extensively exploited in Central Asia despite considerable potential to satisfy unmet electricity demand. The Mountains of Central Asia hotspot consists of two of Asia’s major mountain ranges: the Pamir; and the Tien Shan with the total area covered of about 860,000 square kilometers. Much of the biodiversity and natural ecosystems are in the remote mountain areas and have still to be better studied. Therefore, any human impact directed towards the change of aquatic habitat on these ecosystems have to be thoroughly assessed before implementation.


In light of the above, a key aim of TIIAME NRU’s research was to study the ecological conditions and diversity of the ichthyofauna of mountain and foothill sections of rivers that are promising for the development of environmentally sustainable small hydropower. A special attention within the project is paid to the particular importance of the conservation of the ichthyofauna diversity and habitat conditions as well as other aquatic organisms as an integral component of the sustainable functioning of river ecosystems.


To achieve the Hydro4U project objectives, it is key to perform studies on fish biodiversity, allowing the identification of key species of conservational and economic value, key river habitats based on, e.g., morphological river types or specific river sections, and legal protection sites.

To this aim, the team of TIIAME NRU conducted a series of “Central Asian Big Highlands Expeditions” to assemble baseline data on fish biodiversity and population assemblages, distribution and movements in rivers of CA, including information on measured chemical parameters. These field surveys also enabled knowledge exchange with Central Asian scientists and stakeholders.


To carry out the planned research, a special series of expeditionary research was organized in the mountainous regions of Central Asia. Field studies have been conducted in cooperation with regional research institutions and ichthyologists from Fergana and Termez state Universities (Uzbekistan) and Biological institute of Kyrgyzstan Academy of Sciences. Famous German ichthyologist, Dr. Joerg Freyhof from the Natural Museum of Berlin has participated in spring field studies as well.


To perform the listed tasks, the TIIAME NRU Team has conducted large-scale preparatory work since the end of 2022 – beginning of 2023. More than 50 preliminary planning sites throughout the whole Central Asian highlands were defined.


Before starting our surveys, we faced problems with obtaining permission for electrofishing. After long discussions and organization of two workshops dedicated to explaining the pros and cons, sampling permits for Uzbekistan and Kyrgyzstan were handed out eventually. TIIAME NRU is still aiming to acquire permits for ichtyological studies in Kazakhstan and Tajikistan. Therefore, here we provide data on the two republics of Kyrgyzstan and Uzbekistan.

In general, all research tasks have been fulfilled, despite the difficulty of visiting some distant upstream sections of mountainous rivers due to absence or very bad quality of roads. As a result of conducted field surveys, today we have collected large field data on fish diversity, taxonomy and ecology, as well as hydrology of more than 50 river drainages in Kyrgyzstan and Uzbekistan. Also, for the first time, the main key fish species in upstream sections of Central Asian Mountain rivers have been revealed. The identification of key species to be protected during implementation of different hydrotechnical constructions, including SHP, has high importance for the protection of wildlife.


The TIIAME NRU Team has also continued telemetry studies in Shakhimardan river basin to establish fish migration patterns in connection with the construction of fish passages on water intake and water fall in Koksu river. Results of conducted research have been presented in meetings and conferences and also published in regional journals.

LIFE NEXUS: What if urban water networks could become a source of renewable energy?

The nexus of water and energy, two vital resources, is becoming critical in cities due to demographic movements, economic growth and an inexorable increase in demand. Water scarcity and the need for low-carbon solutions make it a challenge to deliver urban water services without increasing their impact on the environment.


In this context of clean energy transition, LIFE NEXUS wants to show the potential of micro-hydropower systems for recovering untapped energy, deriving from abundant pressure (water head) or kinetic energy (water flow) in European water networks. LIFE NEXUS brings together partners from Spain, Poland and Lithuania, a valuable cross-border network and is coordinated by Hydro4U project partner CARTIF.


The project will install a Small-hydropower plant at the Porma drinking water treatment plant in the Spanish city of León, integrating Pump-as-Turbine (PaT) technology with an energy storage. When fully operational in 2024, this system will supply the plant’s total annual energy demand.


In parallel, no systematic assessment exists of hydropower potential to produce ‘green’ electricity in European urban water networks. LIFE NEXUS is bridging this data gap with the first inventory of potential locations and existing installations. This already contains 104 sites in 10 different European countries, with the information georeferenced and available through a web platform.


The project is building a broad community of stakeholders linked to water services to help identify new locations for its inventory, via a simple online survey. The inventory will feature industrial locations and irrigation areas, as well as urban sites, to promote the project’s transfer.


LIFE NEXUS is a project funded under the LIFE Programme (Ref. LIFE17 ENV/ES/000252) coordinated by CARTIF Technology Centre.

Global Experts Identify Top 100 Questions to Improve Sustainable Management of Hydropeaking

In a newly published study, a team of international experts has identified the top 100 high-priority questions that need to be addressed to improve the sustainable management of peak-operating hydropower, a critical component in the renewable energy landscape. This research, which was partially conducted within the Hydro4U project, is set to shape the future of hydropeaking research, policy, and management.


Hydropeaking, the rapid and frequent changes in river flow to optimize hydropower operation, has gained significant attention due to its ecological impacts and its role in integrating renewable energy production with demand. As the global commitment to renewable energy grows, understanding and mitigating the effects of hydropeaking becomes paramount.


The study employed the Delphi method, a systematic approach to achieving expert consensus, to distill over 400 initial questions to the most pressing 100. These questions span a range of themes, from hydrology and ecology to energy markets and policy. The consensus list aims to guide researchers in focusing their efforts, bridging the gap between science and policy, and ensuring the sustainable operation of hydropower facilities.


Key findings from the study include:

  • A strong understanding of the main ecological impacts of hydropeaking and efficient mitigation techniques exists.
  • There remains to be a disconnect between this understanding and its policy and management implementation.
  • The ecological effects of hydropeaking on certain organism groups (e.g., crayfish, mollusks, and birds), life cycle stages, and key physical processes, such as sediment dynamics, are still largely unexplored.
  • The socio-economic impacts and energy markets of hydropeaking need further investigation.
  • Considering hydropeaking in the broader context of climate change, urbanization, and other global trends is essential for future sustainability.


The study also emphasizes the potential of emerging technologies. Rapid advances in remote sensing and the rise of artificial intelligence offer new avenues for research. These technologies can help develop a new generation of models that consider a wide range of data, from socio-economic drivers to river flows and energy markets.


“This research is a call for a coordinated, global effort to address the challenges and opportunities presented by hydropeaking,” said Dr. Daniel S. Hayes, lead author of the study, and researcher at the University of Natural Resources and Life Sciences, Vienna. “With the identified 100 high-priority questions as our guide, we can direct our research efforts more effectively, providing policymakers with the evidence they need to ensure the sustainable management of rivers.”


The Hydro4U project is proud to have participated in this pivotal research, emphasizing its commitment to advancing sustainable hydropower practices worldwide.
