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.

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.

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.

The question of suitable approaches and technologies for more effective and environmentally friendly management of natural resources has great relevance for the countries of Central Asia in the context of the UN Sustainable Development Goals. Despite the wide range of natural resources, Central Asia is still facing increasing land degradation and water scarcity. These problems are being accelerated by land-use pressure and climate change, which is particularly severe in Central Asia. The following recommendations are developed together with scientists from international projects on the use of GIS technologies and modelling approaches for more sustainable resource management.

In July-August, 2023, CAREC Institute, Public Opinion Research Institute, and Asian Development Bank Institute conducted a sociological survey on household energy use in the Fergana Valley spanning over the Kyrgyz Republic, Tajikistan, and Uzbekistan. The following article uses the data from that survey for investigating what determines the choice of different energy types for heating. The article concludes that high household expenditures for coal and high awareness of the harm fossil fuels can inflict on the environment and family health are insufficient to trigger a large-scale shift towards cleaner energy. To motivate households for such a shift a substantial increase in fossil fuel prices compared to electricity and other clean energy is required. This might call for a sales tax on coal. However, energy expenditure already accounts for up to one-third of household income. Low- and middle-income households would need to be compensated for increased energy spending to avoid social hardship and a backlash against such a tax.

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.

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.

Countries in Central Asia, which are highly vulnerable to climate change, experience a variety of health-related impacts to which they must adapt. At the same time, climate mitigation interventions in the health sector in the form of reduced greenhouse gas (GHG) emissions may also generate co-benefits. This article briefly outlines current understanding of the relationship between climate change impacts and human health in Central Asia and establishes a scope of inquiry based on climate and health linkages as identified by the Intergovernmental Panel on Climate Change (IPCC). It then identifies and summarizes existing research and reporting on this topic in the region as presented in published literature, country reporting to the United Nations Framework Convention on Climate Change (UNFCCC), and gray literature, including policy literature and documentation of donor-funded development interventions in the region. This review, which attempts to summarize and appraise those efforts, has found that both peer-reviewed and grey literature on this topic must be used with caution. The most frequent problems with peer-reviewed and grey literature resources involved confounding bias, and—to a lesser extent—self-reporting bias. The use of an appraisal framework for grey literature sources can frame these diverse resources in the proper context, identify potential shortcomings, and gain insights into current priorities and future direction for research on climate change and health in the region.
