Water diplomacy encompasses the processes and institutions through which the national interests and identities of sovereign states are represented to one another. It is enshrined in international law, which states use to explain and justify their policies to concerned actors in the international system. States mostly prefer traditional tools of water diplomacy such as negotiation and mediation to resolve disputes in transboundary river basins.

The article investigates certain low-cost filtering materials and their filtration efficiency for open well sources in terms of economic access to clean water in Anakapalle, a suburb of Visa-khapatnam, India, during the pre-monsoon period of 2022. The corresponding research aimed to study a selection of filter materials including coconut shell activated carbon, rice husk ash, manganese modified sand, and graphene oxide, as well as assess their performance against selected physico-chemical parameters of water. Considering the basic idea of slow sand and gravity-based filtration, a setup was arranged with a cartridge filled with layers of filtering materials and a ceramic candle filter. Adsorption turned out the most pronounced removal mechanism that took place when utilizing the aforementioned filter materials. The main focus of the study was to reduce pH, TDS, hardness, alkalinity, chlorides and iron content by applying dif-ferent filtration removal mechanisms. The study results show a significant drop in turbidity, pH, TDS and chlorides, and small reduction in hardness when coconut shell activated carbon and rice husk ash were used as filtration media. Whereas the chemically coated medium – manga-nese modified sand – demonstrated a considerable fall in iron concentrations, graphene oxide sand was observed to reduce alkalinity for any sample source.

This study aimed to examine the efficiency of different drip irrigation regimes in spring film greenhouses for early tomato harvesting. The field (small-plot) experiment included designing and testing the watering technology suitable for rural Tajikistan. Irrigation, soil moisture, and tomato growth were followed for several seasons under four irrigation pilots. The experiments showed that the most effective drip irrigation regime for Elpida hybrid tomato was carrying it out while regulating soil moisture within 75-85%, with the irrigation demand of 4,978 m3/ha and irrigation norm of 99.0 m3/ha, also contributing to better water efficiency. The volume of irrigation water for the production of one unit of tomato crop in the second experiment was 5.73 m3/ha, i.e. 14.18% less than in the control plot. The study showed that the tomato evapotranspiration coefficient tends to increase as the threshold of soil mois-ture before and after irrigation grows. The maximum net yield amounted to 1,342 thou. Somoni/ha – 1.9 times or 52.7% higher compared to the control plot. The research findings can guide individual farmers and production facilities, as well as the overall development of agrarian economies like Tajikistan.

MAR remains relatively underutilized in Central Asia despite its potential to address water scarcity issues, particularly those related to seasonal fluctuations in water availability. Thus, the objective of this study was to produce a map depicting the potential suitability of managed aquifer recharge (MAR) implementation in Kazakhstan. Employing a multi-criteria decision analysis framework, five distinct physical criteria were integrated and visualized within a Geographic Information System (GIS) to delineate the intrinsic potential for MAR. To demonstrate the practical utility of the generated map, it was applied to the Zhambyl region in Southern Kazakhstan, an area previously afflicted by water scarcity challenges. The intrinsic MAR potential map was overlaid with remote sensing data identifying potential water sources and water utilization patterns. This overlay facilitated the identification of priority areas with potential for further evaluation for MAR implementation. The map developed for Kazakhstan represents the first spatial representation of MAR potential within the region, serving to raise awareness regarding the feasibility of MAR application. It is anticipated that dissemination of this map will enhance understanding among water management professionals, potentially catalysing the integration of MAR methodologies into regional water management strategies.

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).

In July-August, 2023, CAREC Institute, Public Opinion Research Institute, and Asian Development Bank Institute conducted a sociological survey on household energy use in the Fergana Valley spanning over the Kyrgyz Republic, Tajikistan, and Uzbekistan. The following article uses the data from that survey for investigating what determines the choice of different energy types for heating. The article concludes that high household expenditures for coal and high awareness of the harm fossil fuels can inflict on the environment and family health are insufficient to trigger a large-scale shift towards cleaner energy. To motivate households for such a shift a substantial increase in fossil fuel prices compared to electricity and other clean energy is required. This might call for a sales tax on coal. However, energy expenditure already accounts for up to one-third of household income. Low- and middle-income households would need to be compensated for increased energy spending to avoid social hardship and a backlash against such a tax.

This article explores major findings and evolutions in understandings of transboundary water conflict and cooperation over the last three decades, focusing on the trends emerging from the Transboundary Freshwater Diplomacy Database. It is found that since the 1940s, countries tend to cooperate over shared water resources, in contrast to media portrayals of 'water wars'. Water conflicts, which have increased slightly since 2000, are mostly fuelled by water quantity disputes or unilateral infrastructure developments. Institutions play a role in facilitating cooperation and reducing conflict over shared waters, but their growth and adoption have slowed over the last few decades.
