Central Asia is considered a region highly vulnerable to climate change impact and susceptible to climate-induced migration. Rural populations throughout the region are particularly at risk of experiencing adverse effects of climate variability and (im)mobility due to increased exposure to environmental hazards and distress that can severely affect agricultural productivity. This paper explores how climate change impacts migration trends in rural areas of Central Asia with an aim to contribute to the research on climate mobility in the region focusing on most vulnerable inhabitants. By examining the ongoing region's environmental degradation with increased aridity and retreating glaciers that affect local agriculture, water and food security, this paper suggests possible outcomes of such effects on rural mobility trends across five Central Asian countries.

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.

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.

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.

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.

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.

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.
