https://water-ca.org/article/state-led-cotton-deregulation-in-uzbekistan-reforms-and-effects
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).
