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.

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.

Academic scholarship defines sectoral corruption, namely water corruption one of the main threats to the development of Central Asia. While applying a rapid review, the purpose of this article is to explore the current state of research on water corruption, its various forms, and typologies in different water sectors (such as water supply and sanitation, irrigation, hydropower, and water resources management).

The research aimed to assess the impact of human economic activities on the Yesil River Basin based on the observational data contained in Kazhydromet’s (Republic State Enterprise, RSE) hydrometeorological periodicals of 1933-2019. The additional analysis of numerous sources – statistics digests, online data of the Bureau of National Statistics under the Agency for Strategic Planning and Reforms of the Republic of Kazakhstan (RK), monographs and scientific papers also allowed to reliably evaluate the overall water consumption in the country.

Climate change poses a formidable threat to the Central Asian region, exacerbating preexisting vulnerabilities and necessitating enhanced adaptation efforts. The economic and environmental costs of these changing climatic conditions are substantial, compelling governments to bolster their adaptive capacity. In this study, we employ the United Nations Framework Convention on Climate Change (UNFCCC) adaptation framework and high-quality data to quantitatively measure the capacities of the Central Asian countries to adapt to the impacts of climate change.

This paper aims to foreground the importance of emotions in water diplomacy in general and in Nile water diplomacy in particular. Water diplomacy does not operate from a clean slate, but in a socio-hydropolitically mediated context which is, in turn, imbued with emotions. The existing water diplomacy approach primarily operates with the assumption that the riparian state is a rational actor. However, we argue that emotions have underpinned water diplomacy, including the ongoing Nile negotiations. These emotions are neither acknowledged nor negotiated but are dismissed as irrationality in both the theoretical understanding and practice of water diplomacy.

В статье представлена динамика изменения максимальных запасов воды в снежном покрове в Есильском водохозяйственном бассейне в период 1971–2019 гг. Основной целью работы является изучение динамики изменения влагозапасов снежного покрова, так как снежный покров играет важную роль в климатических, гидрологических и гляциологических процессах, являясь мощным климатообразующим фактором.

Based on Feminist Institutionalism, this paper analyses the reasons for gender disbalance in water diplomacy. To this end, it looks at three intergovernmental decision-making forums on shared waters, namely the Nile Technical Advisory Committee, the Chu-Talas Water Commission, and the International Commission for the Protection of the Rhine. The perceived key obstacles for women’s access to decision-making positions were disciplinary gender divides that go along with a largely technical approach to water management, the gender division of labour, cultural norms, and perceptions of good leadership. While their relevance differed in the different socioeconomic, political and cultural contexts, the overall results show that male dominance in water diplomacy is not only a matter of numerical representation, but enshrined in professional norms and practices.

This study aims to identify the relationship between CO2 emissions and economic growth to assess the influence on climate change. Design: The algorithm was chosen for research provision: statistical and comparative analysis, correlation, and regression analysis. The data for 1999-2020 was obtained from the World Bank and the Bureau of National Statistics. Results: After looking at the conditions and factors that affect Kazakhstan’s energy system, we believe it is essential to study how different factors affect economic growth, with a focus on environmental change. The results of modeling with regression models back this up. The model demonstrated that energy consumption has the most significant influence on CO2 emissions; however, in the GDP model, all factors, such as urbanization, energy consumption, and energy pricing, had an equal impact.

На примере бассейна р. Жабай проведено исследование климатических и гидрологических изменений, дана оценка степени опасности наводнений и возможности их предупреждения и прогнозирования. С 2000 г. в Казахстане наблюдается период стабильного повышения температуры воздуха. В бассейне р. Жабай в этот период наблюдалось сильное наводнение (2014 г.) и разрушительные волны (2017 г.), которые привели к угрозе жизни населения г. Атбасар, расположенного в устье реки. Применение гидравлического моделирования HEC-RAS показало, что степень опасности в восточной части г. Атбасар оценивается как экстремальная (кризисная), а в южной как высокая.
