Recently, Paulownia spec. has been introduced to Central Asia in a number of small plantations. Paulownia yields timber of high quality for applications such as furniture, house construction, boat construction, and surf boards, or skis. Thus, Paulownia might offer a much-needed raw material for this region and beyond. However, Central Asia is largely occupied by drylands so that Paulownia needs irrigation. Against the background of frequent water stress across the region, this study aimed at assessing the water consumption and water productivity of that tree, using a 6-year-old plantation as study site. Trees were planted in May 2017 and cut back to their stumps in 2018. Daily crop evapotranspiration was calculated after the Penman-Monteith approach, whereby the crop coefficients were inherited from actual evapotranspiration values which stemmed from the remote sensing approach S-SEBI. Water consumption per tree was 1741 l, 4461 l, 4500 l, and 4407 l over the growing seasons 2020, 2021, 2022, and 2023, respectively. The water productivity for the stem wood over the whole time-span from planting in 2017 until 2023 was 1.59 g l-1 and 5.65 ml l-1. Given the high quality of its timber and its range of high-value applications, it can be concluded that the water consumed by Paulownia enables higher value timber and timber products than other trees that grow in comparable areas of Central Asia.

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.

This article explores the legal challenges of managing transboundary watercourses in Central Asia in the context of the Eurasian Economic Union (EAEU). The authors analyze whether existing international, regional, and bilateral legal mechanisms are sufficient for regulating shared rivers such as the Syr Darya, Chu, Talas, Irtysh, Ural, and others.

The Badam River, a tributary to the Arys River located in the Syr Darya basin, is a crucial natural resource for ecological, social, and economic activities in the semi-arid region of southern Kazakhstan. The river basin is heavily influenced by manmade water infrastructure and faces water scarcity, particularly during summer, highlighting the importance of understanding its hydrological processes for effective water resource management. In this study, a semi-distributed conceptual hydrological model of the Badam River was implemented using the RS MINERVE hydrological software to evaluate the impacts of climate change on hydrology and to test the resilience of the water system. Connected HBV models were implemented for each of the hydrological response units that were defined as altitudinal zones. The hydrological model was calibrated using daily time steps between 1979 and 2011, and the resulting flow exceedance curves and hydrographs were used to assess the potential impacts of climate change on the basin, using CMIP6 precipitation and temperature scenarios. Future climate scenarios for the 2054 – 2064 period demonstrate that the peak discharge will be shifted to spring/late spring compared to the current early summer with no significant decrease in average discharge per day of the year. The insights gained from this hydrological-hydraulic model can be used to effectively manage the water system and inform future hydropower design decisions and serve as a blueprint for similar studies in the region and elsewhere.

Water is a fundamental precondition for human life. No substitute for freshwater exists, and it is scarce in many regions. Simultaneously, much of it transcends state borders via shared river and lake basins or groundwater aquifers. The resulting political, economic, social and environmental interdependencies give water resources the crucial potential to either foster cooperation or exacerbate conflict. The significance of access to water is growing as demographic and economic drivers as well as deteriorating water quality interact with climate change that will regionally increase water scarcity and variability.

Recent research has focused mainly on factors linking environmental change or stress to violent conflict, while less attention has been paid to conditions that promote cooperation and negotiation. This study presents preliminary findings on environmental, social, and economic indicators that may create favourable conditions for cooperative water resource agreements. The results suggest that inequality among riparian states across physical, economic, and social dimensions can, unexpectedly, facilitate the negotiation of international and regional agreements on shared water resources.
