The article reviews the issues of forming fish populations and studying the current state of commercial fish species in the delta lakes of the Syrdarya River for subsequent effective development of fish farming. In 2020, research works were carried out on lakes Akbilek, Tushchy, Shomishkol, Karakol and Akshatau-Sorgak of Aral District of Kyzylorda Region.
The article reviews the latest available statistical information on gender inequalities in labor markets and in access to financial institutions, social services, and education. After a general review of agricultural development, household food security and rural poverty, population structure, and labor outmigration in Central Asia, the article examines the women’s role in the labor market, including both formal and informal female employment, the feminization of agriculture in the region, gender gaps in education and wages, and constraints on women’s access to extension services and land ownership.
his review paper analyzes the question of how Central Asian countries are presented in land governance indices and assessment frameworks such as the World Bank’s Land Governance Assessment Framework (LGAF), Global Property Rights Index (Prindex), Global Land Governance Index (LANDex), and The Open Data Barometer. The paper uses the integrative review of academic works and the author’s empirical data on Central Asian performance in land governance indices and assessment programs.

The article demonstrates the results of research on concentration of heavy metals in waters of Ural-Caspian basin. One of the most objective and reliable indicators of water pollution and the general anthropogenic load on it is the content of heavy metals in water, bottom sediments (mud’s) and biota.
Water security in Central Asia has been discussed by researchers and international organizations using hydrological, engineering, and modeling approaches. Various frameworks conceptualize water security through technical, socio-economic, and environmental aspects.

The study investigated the effects of pre-ozonation on the parameters such as turbidity, color, chlorophyll and TOC on a pilot scale. The investigation results indicate that the amount of required ozone to remove TOC, color and turbidity depends on the quality of inlet water, and the efficiency of water ozonation depends on the process factors such as ozone dose, temperature, pH and ozone-water contact time.

Covering increasing water demand for competitive uses with limited resources is becoming one of the most challenging water management issues. The effects are more evident in arid areas, where conflicts are more likely to occur. Such an example is Urumqi County, China; Urumqi River is the main water supply source, and in order to balance the upstream agricultural water demand and the downstream urban water demand, the government imposed fallow measures.

The study aimed to assess the efficiency of the pilot hydro-acoustic (sonar) fish protection device (SFPD) installed at the Kokaral Dam of the Small Aral Sea. For this purpose, between August 27 and September 5, 2020 experimental and control fish catching was carried out using fixed fishing nets (30×60 mm mesh).

In Afghanistan, water is mostly used for agricultural purposes. The water supply chain requires updating to ensure its sustainability. Different irrigation methods – such as surface water based irrigation (via canals), groundwater based irrigation, and the Karez irrigation system – are applied across the country. Considering the compatibility of the Karez system with the environment, it can be deemed the most effective irrigation scheme, as it allows collecting a significant amount of groundwater and conveying it to land surface via sub-horizontal tunnels using gravity. This article analyzes Afghanistan’s Karez irrigation systems currently feeding water to over 170,000 ha of farmland with a potential to expand and become a component of sustainable water supply chain.

The study aimed to define the classes in the Heavy Metals Section of the Regional Environmental Ranking System based on long-term data (1997-2017). When distinguishing water quality classes, the following factors were taken into account: background content of heavy metals, content of heavy metals in water bodies exposed to different levels and character of anthropogenic pollution, and response of biological communities to toxic pollution of their natural habitats.
The article analyses the press coverage of gendered labour division in Uzbekistan’s water sector. The study focused on the content, types, methods, forms, techniques and principles of gendered labour division coverage in the Narodnoye Slovo [Popular Word], Pravda Vostoka [The Truth of the East], and Darakchi [The Reporter] newspaper periodicals.

The article investigates the possibility of using snow cover satellite data for short-term hydrological forecasting for Central Asian rivers with high-altitude catchments. The research aimed to elaborate a methodology for forecasting mean 10-day (decadal) river discharge (MDD) of the Varzob and Tar Rivers based on MODSNOW-processed MODIS satellite imagery.

This article presents the study results of the change dynamics in the chemical composition of water in Lake Iskanderkul and the rivers flowing into it, as well as the comparison of water quality in the water bodies of the Iskanderkul Basin and several mid-stream tributaries of the Zarafshan River.
The article aims to analyze water resources use in the Zarafshan River Basin, including calculating the amount of water that can be saved by introducing water-efficient irrigation technologies; testing the hypothesis of the possibility of restoring the Zarafshan’s runoff as a tributary of the Amudarya River, as it was in ancient time; reviewing the experience of developed countries in injecting wastewater into deep aquifers, and the possibility of introducing the corresponding practices in Uzbekistan.

The research group extends sincere gratitude to the reader for the interest in the article and for spending time on addressing the editorial office. The main criticism is expressed in the following phrase: “Thus, 6 (six) satellite images covering 24 years, each of them corresponding to a different season (from July 1 to October 6), cannot characterize the long-term glacier albedo dynamics” [Terekhov, 2020].

One of the study’s objectives was formulated as the analysis of long-term dynamics of the broadband snow and ice albedo of the Ak-Shyjrak Mountain Massif’s glaciers. 6 (six) LANDSAT satellite images taken during 1994-2018 were used to accomplish it.
