Hydro4U project discovers fishes in Koksu River
(Shakimardan enclave, Uzbekistan) for the first time

Until now, no one thought there were fish in the Koksu River located in Shakimardan enclave, Uzbekistan. Also, until today, no literature information on fish catches in this river was registered. This is due to the lack of up-to-date information on aquatic ecology as well as fish biodiversity and migrations in Central Asia. Also, modern techniques for fish ecology studies were missing.


Within Hydro4U project, scientists from the TIIAME NRU team led by Prof. Bakhtiyor Karimov have conducted intensive aquatic ecology studies and for the first time in history, have revealed the presence of two fish species there: snow trout (Schizothorax eurystomus Kessler, 1872) and one loach species (Triplophysa sp.). During a fieldtrip for river ecology studies in the area of the potential small hydropower plant in November 2021, 24 specimen of snow trout of different ages were caught in the midstream of the river above Shakimardan Village, as well as more than 10 snow trout and loach specimen within Shakimardan Village in April 2022, thanks to the employment of electrofishing equipment introduced by Hydro4U project partners.


The caught fish species could serve as indicators for river ecology. Their habitat requirements serve as a basis for habitat studies and ultimately for achieving the goal of implementing environmentally friendly hydropower solutions.


The “Tashkent Institute of Irrigation and Agricultural Mechanization Engineers” National Research University (TIIAME NRU) is a regionally recognised academic and research institute known for its top programmes in engineering (irrigation, water resources, ecology and environment, electrification & automation, agricultural mechanisation, land management and agricultural economics / management & marketing).


In Hydro4U, TIIAME NRU’s core activities are to depict the impact of small-scale hydropower on aquatic and fish ecology in mountain ecosystems and to lead the preparation and dissemination of open-source educational materials.

Hydro4U – European project on sustainable small-scale hydropower in Central Asia meets in Tashkent, Uzbekistan



Hydro4U is a project funded under the European Union’s Horizon 2020 research and innovation programme. Organisations from Europe and Central Asia are collaborating to boost sustainable small-scale hydropower in Central Asia. Eco-friendly hydropower solutions will be implemented in two demonstration plants: one in Kyrgyzstan and one in Uzbekistan. Further sites in Central Asia will be selected as planning sites. This week, the consortium met for two days in Tashkent for a general project meeting together with the project’s Advisory Board team to review the activities of the past twelve months and plan the upcoming actions. The meeting also included a special session with regional EU Delegations to benefit from the expertise of the Commission.

Boosting the replication of European Small-hydropower solutions in Central Asia

Central Asia is a singular region in terms of Small Hydropower (SHP) development. Although the zone has the second largest SHP potential (up to 10 MW) in the world with 34.4 GW, it is the area with the lowest percentage of SHP development, with only 0.8% of SHP exploited so far.[1]


Behind these low figures, there is a great number of political, economic, social, technological, legal and environmental barriers. There are common issues as the lack of information on SHP or the lack of private sector funding. Moreover, some Central Asian countries have to deal with extreme weather conditions which negatively affect hydropower development, as for example in high altitude regions where streams are likely to freeze in winter.


Hydro4U aims to boost European SHP industry by adapting existing European high-quality solutions to the demands and resources of Central Asia. Furthermore, in order to accelerate the exploitation of these solutions, a replication strategy is being elaborated.


CARTIF is a technology Centre with more than 25 years of experience in the development of renewable energy projects and in the definition of strategies for energy transition. In the context of Hydro4U, CARTIF is leading the replication activities. A key point of our work will be the development of a replication guideline tool, aimed at future investors or public authorities to support decision-making on new SHP projects in Central Asia. The tool will be based on a computational model integrating GIS information and statistical data and will be implemented at river basin level.


Currently, it is planned that the tool will consist of several interactive modules, aiming to (1) visualise the total sustainable HP potential and installed capacity, (2) simulate hydropower (HP) generation scenarios considering Water-Food-Energy-Climate Nexus constrains, sustainability of resources and socio-economic impacts and (3) provide HP technology recommendations as well as lessons learnt related to the implementation of new HP projects.


The tool is intended for public use and is therefore not only aimed at experts who are familiar with the specific details, but also at decision-makers, investors and politicians.

Assessments and benefits sharing in the context of the Water-Food-Energy-Climate nexus in Shakhimardan river basin

The International Water Management Institute (IWMI) is a non-profit, research-for-development organisation, based in Colombo, Sri Lanka, that works with governments, civil society and the private sector to solve water problems in developing countries and scale up solutions. IWMI opened a subregional office in Tashkent, Uzbekistan, in 2001. It is the only international institute conducting water research in Central Asia. Together with the numerous partners and stakeholders from their broad network, IWMI tackles the key water management issues facing the region. IWMI identifies the best practices for improving irrigation performance, reversing land degradation, addressing interlinkages in the water-energy-food nexus, improving the efficiency of water and energy use, promoting the economic efficiency of water management, and enhancing transboundary water cooperation and governance in shared river basins. IWMI’s strategy is centered around three strategic programmes – Water, Food and Ecosystems; Water, Climate Change and Resilience; and Water, Growth and Inclusion – each supported by high-quality science and digital innovation.


In Hydro4U, IWMI is responsible to carry out the quantification of shared benefits and trade-off analyses from small-scale hydropower (SHP). The cross-sectoral nexus dimensions need to be fully understood, not only at regional level, but also in the specific local contexts where SHP solutions are planned. Therefore, a seminar was held on 9th March 2022 in Fergana (Uzbekistan) to exchange views with the population and local authorities on the assessment of the nexus interdependence and cross-sectoral distribution of interests. The purpose of the consultation meeting was to discuss with local stakeholders from Ferghana district the importance of the nexus between Water-Energy-Food and Climate in the context of SHP installation in Shakhimardansay, one of the demonstration sites selected under Hydro4U.


Therefore, it is important to understand how SHP will influence other sectors in the region and how it will improve socio-economic conditions of the enclave Shahimaradansay. The aim was to bring together representatives of the water, energy, agricultural and environmental sectors as well as local authorities.


The water, energy and food sectors are so strongly interlinked that actions in one area commonly impact on one or both of the other sectors. Yet, all too often, these sectors operate in isolation, and seeking security in one sector may in fact compromise others or affect negatively the integrity of ecosystems.


In transboundary basins, obtaining harmonised data from all riparian countries and forming a holistic and shared picture of the situation and future scenarios is more complicated and requires specific approaches and policy dialogues. A joint assessment of intersectoral links, trade-offs and benefits serve the development of more coherent policies, reducing frictions between sectors and environmental impacts, as well as promoting the expansion of cross-border cooperation.


The nexus approaches help governments, investors and local communities think about where and how to maintain, restore and improve ecosystems and biodiversity, regenerate agriculture, and support sustainable irrigation, clean energy, and agro-processing needs. The nexus approach involves a broad range of actors (including women, youth and vulnerable groups) and stakeholders working together to connect systems in ways that seek equitable economic and social well-being.


IWMI will assess the cross-sectoral nexus at regional level and in the specific local contexts where SHP solutions are planned.  A situational analysis report and survey to document site-specific characteristics will be prepared. Geospatial analyses will be enriched by interviews with stakeholders in the catchment area to capture detailed socio-economic dimensions on the ground. An investigation will be undertaken to determine to what extent site-specific learnings are transferable to the Central Asian context, to interstate canals and transboundary river basins.


IWMI jointly with other Hydro4U partners will conduct a mapping of the main actors at selected demo and test sites, of their roles and responsibilities and investigate the formal and informal institutions that exist to foster water governance. The robustness of sharing agreements will be screened according to their “climate-readiness”, including from the perspective of the extent of non-cooperation in the respective contexts.
