Political tensions over water management in the Central Asia region have intensified since the Soviet era, as ecological issues like the drying Aral Sea and seasonal hydropower disruptions impact downstream countries. The paper discusses the region’s water governance challenges, including climate-induced uncertainties, water resource demands, and the limited capacity of local research institutions. While Central Asia’s governments have initiated reforms, including new infrastructure and agreements, resilience in water management remains underdeveloped. The paper also explores the role of higher education institutions in fostering capacity-building for sustainable governance, emphasizing the need for local expertise and regional collaboration. The proposed establishment of a Central Asian water research platform aims to enhance science-policy integration, promote sustainable water governance, and support informed regional cooperation on transboundary water issues.

The water, energy, and food (WEF) nexus is being promoted as a conceptual idea for achieving sustainable development, that describes the interconnections and interdependencies between those three sectors. The main objective of this article is to operationalize the WEF nexus concept in lift-irrigated areas of Uzbekistan through involving local stakeholders, to investigate the WEF nexus within the lift-irrigated agriculture of the Kashkadarya region, an area heavily reliant on the Karshi Canal system. The study is grounded in the urgent need for sustainable development, with a focus on enhancing intersectoral cooperation between water, energy, and food sectors. A case study methodology was employed, incorporating semi-structured interviews with experts, alongside local farmers and scientists. Data were analysed using the qualitative analysis software, Atlas.ti. The results indicate significant challenges to intersectoral cooperation in the WEF nexus, including lack of trust, communication barriers, differing priorities, and insufficient political will. However, the findings also highlight the potential benefits of improved cooperation, such as enhanced resource efficiency, reduced operational costs, and mitigated risks from environmental stressors like drought. The study concludes that, according to stakeholders’ opinions, while the WEF nexus presents critical opportunities for advancing sustainable development in Uzbekistan, substantial barriers must be addressed to realize these benefits. Recommendations include promoting sustainable agriculture to reduce water dependency, improving energy security by diversifying energy sources, and raising awareness of the WEF nexus’s importance. Furthermore, fostering stronger stakeholder cooperation is crucial for achieving Uzbekistan’s Sustainable Development Goals (SDGs) by 2030.

Изучены особенности пространственной и временной изменчивости повторяемости атмосферных блокингов над территорией Казахстана в зимние месяцы, а также вариаций ее температурного режима для зимних месяцев. При обнаружении атмосферных блокингов в качестве фактического материала использована информация об изменениях над территорией Казахстана среднечасовых значений атмосферного давления, которые приведены к уровню моря, а также аналогичных значений геопотенциала, соответствующих изобарическим поверхностям 850, 500 и 300 гПа. При оценке влияния атмосферных блокингов на термический режим регионов Казахстана как фактический материал использованы результаты его мониторинга, проводившегося на расположенных в них метеостанциях Казгидромета, а также информация из архивов и электронных ресурсов. Предложена методика обнаружения атмосферных блокингов, обобщающая процедуры, которые традиционно используются для решения рассматриваемой задачи, что позволило снизить вероятности возникающих при этом ошибок. Для различных секторов территории Казахстана для всех зимних месяцев оценены средние значения повторяемости атмосферных блокингов за 1960–2020 гг., продолжительность которых не менее 5–10 суток, тенденции ее межгодовых изменений на отрезках времени, соответствующих различным частям современного климатического периода. Определены климатические нормы повторяемости таких блокингов для современного климатического периода и их изменения по отношению к базовому климатическому периоду (1961–1990 гг.). Также изучено влияние рассматриваемых атмосферных блокингов на термический режим различных регионов Казахстана, который характерен для зимних месяцев. Выявлены регионы Казахстана, где в периоды рассматриваемых атмосферных блокингов возникали наибольшие изменения их термического режима.

Recently, Paulownia spec. has been introduced to Central Asia in a number of small plantations. Paulownia yields timber of high quality for applications such as furniture, house construction, boat construction, and surf boards, or skis. Thus, Paulownia might offer a much-needed raw material for this region and beyond. However, Central Asia is largely occupied by drylands so that Paulownia needs irrigation. Against the background of frequent water stress across the region, this study aimed at assessing the water consumption and water productivity of that tree, using a 6-year-old plantation as study site. Trees were planted in May 2017 and cut back to their stumps in 2018. Daily crop evapotranspiration was calculated after the Penman-Monteith approach, whereby the crop coefficients were inherited from actual evapotranspiration values which stemmed from the remote sensing approach S-SEBI. Water consumption per tree was 1741 l, 4461 l, 4500 l, and 4407 l over the growing seasons 2020, 2021, 2022, and 2023, respectively. The water productivity for the stem wood over the whole time-span from planting in 2017 until 2023 was 1.59 g l-1 and 5.65 ml l-1. Given the high quality of its timber and its range of high-value applications, it can be concluded that the water consumed by Paulownia enables higher value timber and timber products than other trees that grow in comparable areas of Central Asia.

MAR remains relatively underutilized in Central Asia despite its potential to address water scarcity issues, particularly those related to seasonal fluctuations in water availability. Thus, the objective of this study was to produce a map depicting the potential suitability of managed aquifer recharge (MAR) implementation in Kazakhstan. Employing a multi-criteria decision analysis framework, five distinct physical criteria were integrated and visualized within a Geographic Information System (GIS) to delineate the intrinsic potential for MAR. To demonstrate the practical utility of the generated map, it was applied to the Zhambyl region in Southern Kazakhstan, an area previously afflicted by water scarcity challenges. The intrinsic MAR potential map was overlaid with remote sensing data identifying potential water sources and water utilization patterns. This overlay facilitated the identification of priority areas with potential for further evaluation for MAR implementation. The map developed for Kazakhstan represents the first spatial representation of MAR potential within the region, serving to raise awareness regarding the feasibility of MAR application. It is anticipated that dissemination of this map will enhance understanding among water management professionals, potentially catalysing the integration of MAR methodologies into regional water management strategies.

The article investigates certain low-cost filtering materials and their filtration efficiency for open well sources in terms of economic access to clean water in Anakapalle, a suburb of Visa-khapatnam, India, during the pre-monsoon period of 2022. The corresponding research aimed to study a selection of filter materials including coconut shell activated carbon, rice husk ash, manganese modified sand, and graphene oxide, as well as assess their performance against selected physico-chemical parameters of water. Considering the basic idea of slow sand and gravity-based filtration, a setup was arranged with a cartridge filled with layers of filtering materials and a ceramic candle filter. Adsorption turned out the most pronounced removal mechanism that took place when utilizing the aforementioned filter materials. The main focus of the study was to reduce pH, TDS, hardness, alkalinity, chlorides and iron content by applying dif-ferent filtration removal mechanisms. The study results show a significant drop in turbidity, pH, TDS and chlorides, and small reduction in hardness when coconut shell activated carbon and rice husk ash were used as filtration media. Whereas the chemically coated medium – manga-nese modified sand – demonstrated a considerable fall in iron concentrations, graphene oxide sand was observed to reduce alkalinity for any sample source.

В статье приведены результаты изучения морфологической изменчивости сазана (Cyprinus carpio Linnaeus, 1758) в пределах трех крупных водоемов Балкаш-Алакольского бассейна – оз. Балкаш, оз. Алаколь и Капшагайского водохранилища. По трем выборкам сазана обнаружены морфологические различия по ряду признаков (счетные и пластические). При анализе внешних признаков были изучены 24 пластических и 14 счетных признаков. С применением метода обработки цифровых изображений (MorphoJ) проанализированы различия сазана по форме тела. Применение метода главных компонент (PCA) позволило определить основные нагрузки на изученные морфологические признаки сазана. Выявленные статистически достоверные различия позволяют говорить о том, что формирование морфологических изменений сазана было вызвано длительностью адаптивной радиации, средовыми факторами водоемов и ежегодным искусственным зарыблением молодью.

Река Бадам, приток реки Арыс, входящая в состав Сырдарьинского бассейна, представляет собой важнейший природный ресурс для экологической и социально-экономической деятельности в зоне полузасушливого климата Южного Казахстана. Существенное влияние на речной бассейн оказывает искусственная водная инфраструктура. Бассейн также сталкивается с дефицитом воды, особенно летом, что подчеркивает важность понимания гидрологических процессов, происходящих в его границах, для эффективного управления водными ресурсами. В рамках настоящего исследования с целью оценки воздействия изменения климата на гидрологию и анализа устойчивости водной системы на базе гидрологического программного пакета RS MINERVE была создана полураспределенная концептуальная гидрологическая модель р. Бадам. Связанные модели HBV были реализованы для каждой из гидрологических единиц реакции, которые были определены как высотные зоны. Гидрологическая модель была откалибрована с использованием дневных временных интервалов за период с 1979 по 2011 гг. Полученные кривые вероятности превышения стока и гидрографы были использованы для оценки потенциального воздействия изменения климата на целевой бассейн с использованием сценариев осадков и температуры CMIP6. Будущие климатические сценарии на период 2054-2064 гг. указывают на смещение пикового стока на весенний/поздневесенний период по сравнению с текущим ранним летом без значительного снижения среднесуточного стока в течение года. Созданная гидрологико-гидравлического модель и результаты моделирования могут быть использованы для обеспечения эффективного управления водной системой и обоснования будущих гидроэнергетических проектов, а также могут служить основой для проведения аналогичных исследований в регионе и за его пределами.

The Badam River, a tributary to the Arys River located in the Syr Darya basin, is a crucial natural resource for ecological, social, and economic activities in the semi-arid region of southern Kazakhstan. The river basin is heavily influenced by manmade water infrastructure and faces water scarcity, particularly during summer, highlighting the importance of understanding its hydrological processes for effective water resource management. In this study, a semi-distributed conceptual hydrological model of the Badam River was implemented using the RS MINERVE hydrological software to evaluate the impacts of climate change on hydrology and to test the resilience of the water system. Connected HBV models were implemented for each of the hydrological response units that were defined as altitudinal zones. The hydrological model was calibrated using daily time steps between 1979 and 2011, and the resulting flow exceedance curves and hydrographs were used to assess the potential impacts of climate change on the basin, using CMIP6 precipitation and temperature scenarios. Future climate scenarios for the 2054 – 2064 period demonstrate that the peak discharge will be shifted to spring/late spring compared to the current early summer with no significant decrease in average discharge per day of the year. The insights gained from this hydrological-hydraulic model can be used to effectively manage the water system and inform future hydropower design decisions and serve as a blueprint for similar studies in the region and elsewhere.
