Исследование лавинной деятельности в горных регионах является важным аспектом для обеспечения безопасности населения и защиты инфраструктуры. Особое внимание уделяется изучению лавин в труднодоступных и малоизученных горных районах, одним из которых является Гиссаро-Алай. Удаленность, труднодоступность и повышенная облачность в период наибольшей лавинной активности делают полевые наблюдения и использование оптических спутниковых снимков для исследования лавинной деятельности в Гиссаро-Алае крайне затруднительными. В таких условиях оптимальным решением становится применение радиолокационных технологий, позволяющих получать данные независимо от погодных условий и условий освещенности. В статье описывается методика обработки радиолокационных снимков спутника Sentinel-1, а также результаты дешифрования лавинных отложений, которые были получены для Зеравшанского, Гиссарского, Туркестанского и Алайского хребтов в сезоне 2021/2022 гг. Проведена верификация метода при помощи мультиспектральных данных со спутников группировки Sentinel-2. Для каждого из хребтов Гиссаро-Алая приведены особенности лавинной деятельности – распределение отдельных мест залегания лавинных отложений по абсолютной высоте, крутизне и экспозиции склонов.

Pollution and over-exploitation of groundwater aquifers in Kabul Province have led to deteriorated water quality and decreased quantity. In its turn, these have caused elevation of physical, chemical, and biological contaminant concentrations in the province’s groundwater beyond national and international drinking water quality standards. The article describes the outcomes of a pilot photovoltaic reverse osmosis (PV-RO) system for drinking water treatment in Qala-e-Gulbaz Village, Kabul Province, Afghanistan. The main system’s components include PV solar panels, three dosing pumps, two alternative current pumps, two alternative-to-direct-current inverters, sand and carbon filters, two sediment filters, one ultra-violet filter, two water flow meters, and a complete water supply distribution system. The study was assisted by the Danish Committee for Aid to Afghan Refugees (DACAAR) ground monitoring well (GMW) system; quality analysis of different physical, chemical, and biological parameters of raw and filtered water samples; measuring filtered water and wastewater flow rates; determining associated limitations and pressures; as well as valuating different related expenses during cost per capita calculations. Water quality testing has shown the system’s removal efficiency of 97% for salinity, 97% for total dissolved solids, above 90% for other chemicals (anions & cations), 65.52% for turbidity, and 100% for bacteria. The plant’s mean quantity efficiency has amounted to 50%. The study highlights certain key challenges including high initial cost, significant wastewater volume, and need for professional operators leading to high operational and maintenance expenditures, with the initial system’s cost per capita of USD79.54. Therefore, under the condition of optimizing efficiency, improving wastewater management, reducing original costs, implementing training programs, and developing the necessary policy framework PV-RO water treatment systems represent a viable alternative.

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.

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 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.

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.

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 study aimed to evaluate the economic and financial viability of a coal mine methane (CMM) utilization project in Central Kazakhstan, demonstrating a methodology for similar initiatives. The analysis was based on the 2013 project proposed by the US Environmen-tal Protection Agency (EPA) that intended to capture methane emissions from six coal mines for electricity generation, yet was never implemented. The study’s relevance stems from Kazakhstan's 2030 methane pledge, recent progress in the country's climate change-related policy, mineworker mortality in 2023, and the shift of mines ownership. Building upon the technical specifications of the 2013 US EPA project, this research em-ployed standard financial and economic cost-benefit analysis (CBA). The financial model utilized a traditional discounted free cash flow approach, while the economic model in-corporated additional factors like the value of statistical life (VSL), shadow pricing, as well as benefits associated with mitigating ozone health impacts, crop damage, mine ex-plosion risks, and CO2 emissions. The economic model has indicated a positive net pre-sent value of $243 mln and 42% internal rate of return. The financial analysis also sug-gests potential profitability under fair electricity and carbon pricing market conditions. To assess project robustness under varying economic and financial assumptions, the study included a sensitivity analysis. The research has likewise leveraged prior CMM-related studies in Kazakhstan and provides valuable guidance for analyzing similar projects. In addition, it also highlights the need for certain adjustments in the current legislation to incentivize such projects, as well as to promote environmental sustainability and social development by mitigating methane emissions, which aligns with Kazakhstan's climate goals.

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.
