Возрастающая нагрузка на водные ресурсы, а также международные обязательства Казахстана по Повестке дня на период до 2030 г. определили необходимость скорейшей модернизации водохозяйственной инфраструктуры промыш-ленных предприятий. Между тем (в условиях отсутствия объективных гидроэкологических данных и нормативной неопределенности) принятие технологических решений по очистке и использованию шахтных и карьерных вод сопряжено водными рисками для горнодобывающей отрасли производства. Данные факторы послужили поводом для подготовки аналитического обзора с целью более широкого информирования заинтересованных сторон о существующей проблеме. Фундаментальный контекст статьи определяется научно-теоретическим сопоставлением существующей законо-дательной структуры регулирования водопользования с институциональной политикой Целей устойчивого развития № 6 (ЦУР 6) «чистая вода и санитария». В качестве ключевого аспекта исследований выступает «комплексный» индикатор 6.4.2. ЦУР «уровень водного стресса», сквозная взаимосвязь которого с другими индикаторами ЦУР 6 позволяет представить всесторонний анализ в вопросе надлежащего исполнения национальных стратегий РК по устойчивому управлению водными ресурсами. Результаты исследований показали, что несмотря на довольно полную законодательную интеграцию ЦУР в нормативно правовые акты (НПА) Казахстана, их реализация в виде экологических нормативов требуют критической переоценки для возможности практического применения при идентификации горнодобывающими предприятиями наилучших доступных техник (НДТ). Несостоятельность экологических нормативов обусловлена слабым межведомственным взаимодействием, размытом понимании ответственности, формальным характером участия промышленного и научного сообщества в разработке, экспертной оценке и научном сопровождении проектов НПА.

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.

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.

This chapter explores the symbiotic relationship between international law and water diplomacy, emphasizing their role in promoting peace and security in the governance of shared water resources. The author examines the key legal principles that underpin interstate cooperation, including the principles of equitable and reasonable utilization and the obligation not to cause significant harm.

This study explores pathways to transformation through a focus on water relations among states, examining the intersection of water resources management, political conflicts, and historical grievances: (1) Ukraine and Russia regarding North Crimea Canal; and (2) Afghanistan and Pakistan in Kabul River Basin. Using these cases to support water conflict prevention, this study explores water interactions (disputes, arrangements, and agreements) from the time of respective sovereign statehoods: Afghanistan (1919), Pakistan (1947), and Ukraine and Russia (1991) through to 2022. The design of this study incorporates the Transboundary Waters Interaction Nexus (TWINs) framework to assess past water interactions; with the Four Stages of Water Conflict Transformation framework, used to assess 2022 state-level relations to determine collaborative skills to cultivate water transformation. Findings indicate that while Ukraine- Russia water relations are adversarial, and Afghanistan-Pakistan are in the reflective negotiation stage—territorial disputes and political economic dynamics hamper cooperation, though points of leverage (such as neutral third-party mediation, shared environmental and economic interests, and water diplomacy and legal frameworks) exist. This research provides value through broadening preventative and transformative strategies in politically sensitive and geopolitically unstable regions—showing that water can be a catalyst for equity and regional securitization.

Why water monitoring and assessment are important?

Water quality assessment is one of the crucial scientific and practical analyses to identify the possibility of water consumption for different human needs and nature/ecosystem conservation for future generations. Water quality can be measured and monitored in rivers, springs, creeks, swamps, estuaries, wetlands and lakes what is called aquatic systems. Quality parameters, such as biological, chemical and physical indicators identify the combination of values that influence the composition of water. Monitoring and comparison of different water habitats (macro invertebrates) in biological monitoring provides an information of water quality and allows to make a quick assessment.

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.

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.

This study aimed to evaluate the suitability of Kabul Province’s groundwater for drinking by way of analyzing the data collected from 34 ground monitoring wells. The purpose was helped through the assessment of a set of groundwater physico-chemical parameters (pH, turbidity, total dissolved solids (TDS); sulfate, fluoride, nitrate, and boron content; total hardness (TH) as calcium carbonate, sodium, calcium, magnesium, and total iron), as well as the determination of the Water Quality Index (WQI) developed based on sampling the water points located in the districts of Kabul Province and Kabul City in the course of 3 years (2018 to 2020) to provide a clear and concise representation of water quality status, and cat-egorize groundwater into different quality classes ranging from “excellent” to “unsuitable for drinking”. Moreover, the spatial distribution of WQI and 12 physico-chemical parameter values was mapped using the Inverse Distance Weighted (IDW) Interpolation in Arcmap 10.7 environment, revealing distinct water quality patterns across the study area. The water qual-ity testing outcomes under this investigation show compliance of multiple water contaminant concentrations with the World Health Organization (WHO) Water Quality Guidelines and Afghanistan National Drinking Water Quality Standards (ANDWQS). The WQI values range between 27.5 and 112 (as per ANDWQS) and between 33 and 127.5 (as per WHO Guide-lines); the WQI (WHO) display 9% and WQI (ANDWQS) display 3% of groundwater unsuit-able for drinking. Spatial variation maps (IDW Interpolation) demonstate that turbidity, TDS, TH, and magnesium concentration values for the provinces’s central and eastern sec-tions exceed the permissible thresholds. The study’s findings underscore the need for target-ed groundwater management strategies, including pollution control and regular monitoring, to safeguard water quality and public health in Kabul Province.

Энергетический переход продолжается с беспрецедентной скоростью и масштабом, требуя новых технологий с низким уровнем выбросов углерода. Зеленый водород рассматривается как часть решения для достижения декарбонизации промышленности, что потребует согласованных действий со стороны промышленности и правительства для того, чтобы Казахстан смог получить выгоды.

Climate change poses various challenges for agriculture and water management practices in Central Asia (CA). Central to these challenges are cryosphere dynamics, fragile mountain ecosystems, and ongoing natural hazards that highlight the need for robust projections of regional climate change. For the first time, dynamic downscaling was conducted in Central Asia at a spatial resolution of 5 km.

Aquatic plants, including duckweed (Lemna minor), are increasingly utilized in sewage and wastewater treat-ment to improve pollution parameters and organic matter removal.

Abnormalities in hydraulic conditions inside a water distribution network are strongly related to the deterioration of drinking water quality.

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.
