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.

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).

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.

Land restoration in Kazakhstan plays a pivotal role in addressing both climate change mitigation and biodiversity conservation. The country faces significant challenges related to land degradation, including driven by deforestation and shrubland loss, which has substantial economic and environmental impacts. By restoring forests, Kazakhstan can enhance carbon sequestration, particularly in regions such as Eastern Kazakhstan, which has shown notable gains in carbon sinks from land use and land cover changes. Restoration initiatives also align with Kazakhstan’s commitments under the Bonn Challenge, aiming to restore millions of hectares of degraded land by 2030. By analyzing land cover changes from 2001 to 2020, we identified key degradation hotspots and quantified economic losses of approximately 5.6 billion USD, primarily in grasslands and forests. Evaluating three socioeconomic and climatic scenarios—Optimistic, Base, and Pessimistic—revealed that restoration investments ranging from 6.7 to 11.6 billion USD could yield benefit-cost ratios between 1.4 and 4.3, with wetlands and forests restoration emerging as priority areas. These findings highlight the need for an integrated, data-driven approach to align economic viability with environmental sustainability, thereby promoting green growth and enhancing long-term resilience. Land restoration can serve as a cornerstone for achieving Kazakhstan’s environmental goals, fostering synergies between climate mitigation, biodiversity protection, and sustainable development.

Recycling is one of the key components in reduction of carbon emissions and improving environmental conditions, especially in the urban context. In Central Asia, the legislation and infrastructure necessary for waste management is still under development. Thus, the knowledge gap and public awareness campaigns are mostly done at the grassroots level. This paper looks at the case of recycling promotion through civic community initiatives that also have a charitable component in Almaty. It explores the ethical considerations that are being entangled with the introduction of recycling culture in the city and is grounded in the literature on civil society, environmental ethics and social entrepreneurship. The data was collected through semi-structured interviews with organizers of recycling fairs and NGOs working on recycling. The paper reveals that by appealing to the ethical considerations of people to “do good” and contribute to charitable cause, the organizers of the recycling fair also demonstrate the effects of over-consumerism, ways of doing waste management, and educate about reuse and upcycle culture. The single case of Darmarka in Almaty present a limitation of the study. Therefore, a more in-depth research on the organisation of Darmarka events in other cities in Kazakhstan and CIS, as well as on similar initiatives in other Central Asian countries would be beneficial in the future. This is an important contribution in understanding what challenges and opportunities exist in promotion of recycling in Central Asia, that can be useful to national governments, experts, and international organizations working in this area.
