    Soil salinity in Central Asia negatively impacts soil structure, leading to degradation and reduced water infiltration. This not only hampers agricultural productivity but also makes the land less suitable for construction due to its high susceptibility to deformation. Environmentally friendly materials like biochar, a carbon-rich substance, show promise in reducing the deformation of saline soils. However, the mechanisms behind its effectiveness are not yet fully understood. This study aims to analyse saline clays’ dispersion and sedimentation behaviour under varying pore water salinity levels (0 % to 10%). A biochar content of 5 % was selected as it is found to be optimum for plant growth and erosion resistance. It was found from the study that the biochar increases the aggregation of soil particles and enhances flocculation, improving soil dispersion characteristics. Biochar facilitates soil particle aggregation by increasing the cation exchange capacity. At higher pore water salinity levels (5% and 10%), the sedimentation behaviour of biochar-treated soil particles deviates from expectations, showing slower sedimentation rates and lower sedimentation heights. This is because the sodium ions are adsorbed by biochar, reducing salt’s effect on dispersion and sedimentation. The results demonstrate that biochar effectively enhances the stability of saline soils and, hence, has a potential use for ground improvement in the Central Asian region.

    HBV-modeling of the Ile Alatau mountain river flow

    Year: 2024

    Collections: Scientific Publications

    Topics: Water

    Authors: Tillakarim T., Serikbay N., Satmurzayev A., Sairov S.

    Countries: Kazakhstan

    The research aimed to evaluate the possibility of applying the HBV model for assessing the flow of the Ile Alatau Mountain Range rivers. The main part of the corresponding water resources forms on the northern slopes of the Ile Alatau making them a significant water balance and water supply factor for the major cities of Almaty, Kaskelen, Talgar, and Yesik.

    Differentiated regional policy approach for the development of monotowns in Kazakhstan

    An individual monotown is a unique combination of available resources, trends and potential. Earlier management decisions, due to their uniformity, did not take such specifics into account. As a result, state support measures have not had the expected effect. The introduction of a differentiated approach to regional policy transformation can therefore be a trigger for positive change.

    Current and potential conflicts for ecosystem services caused by agricultural land use in Central Asia, and essential implications for research on sustainable land management in the region

    Year: 2023

    The increasing demand for food, bioenergy and other agricultural products, as well as the intensification of climate change, pose special challenges for Central Asia’s agricultural sector in terms of implementing sustainable land management. Central Asia is a climate change hot spot. Adaptation measures of agricultural land use to climate change imply new trade-offs in terms of quality and provision of ecosystem services. Based on literature studies, this paper identifies examples of such trade-offs and presents possible solutions. The ecoregions of Central Asia show strong interdependencies. Therefore, a special focus has to be put on the transregional effects of the use of ecosystem services. Against the background of different concepts of sustainable development (ESS, SDG, Global Environmental Syndromes) integrative approaches for sustainable use and design of landscapes are necessary.

    Water resources and water security in Central Asia

    Year: 2022

    Adaptation to expected water shortage and increasing water demand has to be undertaken to achieve water security in the future. In-depth studies on the quantification of climate change impact on water resources should be considered. Optimization of water management practices should consider the best economic value between Central Asian countries. Decision making process on water management should be supported with more scientific knowledge. Capacity building measures on the assessment of water availability in times of climate change should be improved.
