The article is devoted the issue of cre-ating the geoinformation systems for hydroecological monitoring as a support tool for information systems in the Aral sea basin and the optimization models in the development of environmentally acceptable modes of operation of hydraulic structures. In this scientific work presents the experience of works on creation of geoinformation systems using remote methods La information support, with a study of the technical parameters of the hydropower and irrigation facilities on the pool level of the river Amudarya and Syrdarya. The results allow to organize a more rational use and conservation of land and water resources with sustainable exploitation of hydropower and irrigation structures of Uzbekistan.

The article discusses the experience of using the methodology the hydroecological monitoring technique to obtain the results of the analysis of the ecological conditions of hydraulic structures in Uzbekistan. - The examples of the methodology for creating digital maps for information support, for the study of the technical parameters of hydropower and irrigation facilities at the level of the Amudarya and Syrdarya river basins; - Improved trash-holding devices necessary to protect the pumps of hydraulic structures from getting litter and floating objects into them (plastic requires special attention) that can interfere with the normal operation of the units, eliminated during preliminary water treatment; - The results of hydroecological monitoring using geographic information systems, digital maps are shown, which allow for the design, repair and repair of hydraulic structures to take into account terrain, hydrography and other factors. The obtained methodology allows a more realistic assessment of the hydroecological situation, taking into account their influence on hydraulic structures. The methodology of hydroecological monitoring will provide people with information in search of actions to develop environmentally acceptable modes of operation of hydraulic structures in Uzbekistan. Water management organizations can use this system to plan work and predict the environmental situation at all water objects in the Aral Sea basin. This system can be considered as a scientific tool for a decision support system for decision makers. Key words: geoinformation technologies and ecology, hydraulic structures, waste disposal devices, pumps, hydroecological and hydraulic monitoring.

Endophytes associated with halophytes may contribute to the host’s adaptation to adverse environmental conditions through improving their stress tolerance and protecting them from various soil-borne pathogens. In this study, the diversity and antifungal activity of endophytic bacteria associated with halophytic samples growing on the shore of the western Aral Sea in Uzbekistan were investigated. The endophytic bacteria were isolated from the nine halophytic samples by using the culture-dependent method and identified according to their 16S rRNA gene sequences. The screening of endophytic bacterial isolates with the ability to inhibit pathogenic fungi was completed by the plate confrontation method. A total of 289 endophytic bacterial isolates were isolated from the nine halophytes, and they belong to Firmicutes, Actinobacteria, and Proteobacteria. The predominant genera of the isolated endophytic bacteria were Bacillus, Staphylococcus, and Streptomyces, accounting for 38.5%, 24.7%, and 12.5% of the total number of isolates, respectively. The comparative analysis indicated that the isolation effect was better for the sample S8, with the highest diversity and richness indices. The diversity index of the sample S7 was the lowest, while the richness index of samples S5 and S6 was the lowest. By comparing the isolation effect of 12 different media, it was found that the M7 medium had the best performance for isolating endophytic bacteria associated with halophytes in the western Aral Sea Basin. In addition, the results showed that only a few isolates have the ability to produce ex-enzymes, and eight and four endophytic bacterial isolates exhibited significant inhibition to the growth of Valsa mali and Verticillium dahlia, respectively. The results of this study indicated that halophytes are an important source for the selection of microbes that may protect plant from soil-borne pathogens.

Energy plays an essential role in the modern society and can serve as one of the vital parameters of socio-economic development. Despite developments in technology, over three billion persons living in rural parts of the low- and middle-income countries continue to cover their energy needs for cooking through traditional ways by burning biomass resources. This paper as a case study focuses on the Aral Sea region of Uzbekistan, possessing a well-developed agricultural production with high livestock numbers and intensive crop production. The manure of the livestock farms is not used efficiently and the energy supply of the farms depends primarily on centrally produced gas and electricity. Some areas are not yet connected to the gas grid. Agriculture causes huge environmental damages in its current form. The benefit of biogas production would therefore be fivefold: (1) local energy source, (2) mitigation of environmental impacts, (3) reducing CH4-emissions, (4) producing organic fertilizer as a side product and (5) additional earnings for farmers.

Water security issues arising from the Central Asian states’ heavy reliance on, and competition over, the shared waters of the Aral Sea Basin have attracted urgent political and academic discussion. However, any analysis of the role that international law plays in addressing these substantive complex problems remains incomplete and imprecise. This article sets the stage for a deeper understanding of international law and of its potential operation in the context of the transboundary waters in the Aral Sea Basin. It seeks to explore the substantive norms operating in the field, namely, the rule of equitable and reasonable use, the no-harm rule, and obligations relating to environmental protection, with a view to understanding how these substantive norms work and ascertaining what conduct is required of the states with respect to their shared watercourses.
