The article presents the results of investigating the morphological variability of carp (Cyprinus carpio Linnaeus, 1758) in three large reservoirs of the Balkash-Alakol Basin – Lake Balkash, Lake Alakol, and Kapshagay Reservoir. Morphological differences in several features (counting and plasticity) were found in three carp samples. The study included the examination of 24 plastic and 14 counting features. The method of digital image processing (Morpho J) was applied to analyze the differences of the target fish species specimens by body shape. The application of the principal component analysis (PCA) method allowed determining the main loadings on the studied morphological traits of carp. The statistically reliable differences revealed allow to confirm the formation of morphological changes in carp caused by
the duration of adaptive radiation, environmental factors of water bodies and annual artificial stocking of young fish.

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.

This study aimed to examine the efficiency of different drip irrigation regimes in spring film greenhouses for early tomato harvesting. The field (small-plot) experiment included designing and testing the watering technology suitable for rural Tajikistan. Irrigation, soil moisture, and tomato growth were followed for several seasons under four irrigation pilots. The experiments showed that the most effective drip irrigation regime for Elpida hybrid tomato was carrying it out while regulating soil moisture within 75-85%, with the irrigation demand of 4,978 m3/ha and irrigation norm of 99.0 m3/ha, also contributing to better water efficiency. The volume of irrigation water for the production of one unit of tomato crop in the second experiment was 5.73 m3/ha, i.e. 14.18% less than in the control plot. The study showed that the tomato evapotranspiration coefficient tends to increase as the threshold of soil mois-ture before and after irrigation grows. The maximum net yield amounted to 1,342 thou. Somoni/ha – 1.9 times or 52.7% higher compared to the control plot. The research findings can guide individual farmers and production facilities, as well as the overall development of agrarian economies like Tajikistan.

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.

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.

Recycling is one of the key components in reduction of carbon emissions and improving environmental conditions, especially in the urban context. In Central Asia, the legislation and infrastructure necessary for waste management is still under development. Thus, the knowledge gap and public awareness campaigns are mostly done at the grassroots level. This paper looks at the case of recycling promotion through civic community initiatives that also have a charitable component in Almaty. It explores the ethical considerations that are being entangled with the introduction of recycling culture in the city and is grounded in the literature on civil society, environmental ethics and social entrepreneurship. The data was collected through semi-structured interviews with organizers of recycling fairs and NGOs working on recycling. The paper reveals that by appealing to the ethical considerations of people to “do good” and contribute to charitable cause, the organizers of the recycling fair also demonstrate the effects of over-consumerism, ways of doing waste management, and educate about reuse and upcycle culture. The single case of Darmarka in Almaty present a limitation of the study. Therefore, a more in-depth research on the organisation of Darmarka events in other cities in Kazakhstan and CIS, as well as on similar initiatives in other Central Asian countries would be beneficial in the future. This is an important contribution in understanding what challenges and opportunities exist in promotion of recycling in Central Asia, that can be useful to national governments, experts, and international organizations working in this area.
