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.

Universities and academia in Central Asia play a crucial role in addressing climate change impacts, including rising temperatures, diminishing water resources, and increased frequency of extreme weather events threatening agriculture and livelihoods. Academic efforts must prioritize research on tailored adaptation strategies to foster resilience and sustainability. However, there's an underrepresentation of climate change research from Central Asia, emphasizing the urgent need for expanded research efforts.

Uzbekistan’s cotton supply chain experienced a wave of deregulation reforms in the last five years. This paper attempts to assess the process and results of the State-driven transition from the centrally planned cotton sector to private cotton-textile clusters. The article employs secondary data sources to analyse the effects of the deregulation policies descriptively. The study reveals that the deregulation reforms increased productivity in the sector. The reform initiatives also vertically integrated the cotton supply chain from production to marketing. However, the reforms failed to transparently incorporate and harmonise the needs of cotton farmers that grow and sell raw cotton. Consequently, the promises of the State-led deregulation reforms and initiatives are eroded. The article highlights the emerging risks and tensions in the current cotton liberalisation and privatisation reforms in Uzbekistan.

The study was conducted in 2023 and comprised a comparative assessment of the state of Lake Markakol’s aquatic ecosystems in surface and bottom water strata. The analysis of bottom water temperatures showed correlation between this parameter and dissolved oxygen concentrations, indicating that pollution caused by organic impurities leads to lake eutrophication, in turn, pro-pelling the extinction of aquatic life. Although the main water physicochemical parameters of Markakol Lake correspond to the oligotrophic type, the shifts in dissolved oxygen and phos-phate content, as well as growth of aquatic vegetation indicate its transition to the mesotrophic type. Higher phosphate content in water is a consequence of pollution disturbing the biological balance, as well as stimulating the reservoir’s eutrophication and increased biological productivity, i.e. algal bloom. In addition, phosphate ions serve an informative indicator of Hazard Class 3 (organoleptically hazardous) anthropogenic pollution. Based on the correlation factor (r), two statistical models were considered for the target lake: 1) Water Pollution: nutri-ent concentrations depending on surface and bottom water temperatures (Model 1); and 2) changes in Water Pollution Indices (biogenic, heavy metals, mean) because of air temperature growth due to global warming of 0.25°C/decade (Model 2).
