    Mapping the potential for managed aquifer recharge in Kazakhstan

    Year: 2024

    Collections: Scientific Publications

    Topics: Water, Sustainable Development

    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.

    Morphological variability of Cyprinus Carpio Linnaeus, 1758 in water bodies of the Balkash-Alakol basin

    Year: 2024

    Collections: Scientific Publications

    Topics: Water

    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.

    Visible light photocatalytic degradation of HDPE microplastics using vanadium-doped titania

    Year: 2024

    Collections: Scientific Publications

    Topics: Water

    Efficient strategies are necessary to effectively remove microplastics (MPs), which are widely present in the environment. Among various techniques, photocatalysis using visible light has emerged as a promising ap-proach to tackle the growing concerns surrounding microplastic waste.

    Anthropogenic Impacts in the Yesil River Basin

    Year: 2023

    Collections: Research Paper

    Topics: Water

    Authors: Makhmudova L., Mussina A., Ospanova M., Zharylkassyn A., Kanatuly A.

    Countries: Kazakhstan

    Source: Central Asian Journal of Water Research

    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.

    Measuring the Capacity for Adaptation to Climate Change in Central Asia

    Year: 2023

    Collections: Scientific Publications

    Topics: Climate

    Authors: Sabyrbekov R., Overland I.

    Countries: Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan

    Source: Central Asian Journal of Sustainability and Climate Research

    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.

    Development of low-cost rainwater harvesting to support on-site water supply in rural Tajikistan

    Year: 2023

    Collections:

    Topics: Water, IWRM

    Farmers in remote, arid areas, far from available water sources, need affordable water solutions for household and livestock use. In this study, the water needs and potential for rainwater harvesting (RWH) in the Kysylsu River Basin are estimated at different altitudes.
