“…В следующем коллективном труде американских ученых предлагается использовать дистанционное зондирование для 2021/2 каталогизации озер, чтобы охарактеризовать морфологию и построить типологию с помощью кластерного анализа. Этот метод можно будет использовать для определения природоохранных потребностей в научных исследованиях, адаптировать программы водного мониторинга и управления, настроить экологические программы и использовать сохранение имеющихся водных ресурсов более эффективно для достижения крупномасштабных целей управления [31].…”

The article analyzes the legal basis for maintaining the state water cadastre of Uzbekistan as one of the mechanisms for ensuring water security and solving the problem of water resources deficit in the country. The author reveals the essence and goals of maintaining the state water cadastre in the implementation of water resources management as a geographic information system about waters and water bodies; summarizes the latest trends in improving the legal and technological foundations for the formation of water cadastre information in order to ensure its transparency through the use of innovative methods, and discloses the powers of the authorities that lead it. Along with the analysis of positive changes in the water cadastre system, the author disclosed some scientific and practical problems related to the formation of water cadastre information, the solution of which would contribute to ensuring the transparency of information about water resources and its reliability. In addition, the author studied the water cadastre legislation of some CIS countries in terms of the very concept of “water cadastre,” as well as the advanced experience of some developed countries of Europe, Asia, and the USA in the field of water resources management and the role of water statistics in it, and gave a comparative assessment. Based on the analysis of the current water legislation, special legal literature and foreign experience, the author provided proposals for further improving the water cadastre legislation and three drafts of normative legal acts were developed for legal regulation of the water cadastre maintenance, the procedure for conducting the economic assessment of water resources, as well as the procedure for providing water cadastre information to interested individuals and legal entities.

“…Management of landuse disturbances can reverse and possibly improve or restore stream habitat condition (Flávio et al, 2017;Lenhart et al, 2018). Nevertheless, implementation of conservation practices in the MAV has been slow, partly because much of the land is privately owned and thus in most cases economics drive the decision-making process, and partly because of a lack of a largescale view of aquatic resources to guide conservation (Miranda et al, 2021).…”

The effects of agriculture and flood control practices accrued over more than a century have impaired aquatic habitats and their fish communities in the Mississippi Alluvial Valley, the historic floodplain of the Lower Mississippi River prior to leveeing. As a first step to conservation planning and adaptive management, we developed and tested a conceptual model of how changes to this floodplain have affected stream environments and fish assemblages. The model is deliberately simple in structure because it needs to be understood by stakeholders ranging from engineers to farmers who must remain engaged to ensure effective conservation. Testing involved multivariate correlative analyses that included descriptors of land setting, water quality, and fish assemblages representing 376 stream samples taken over two decades and ranging in Strahler stream order from 1 to 8. The conceptual model was adequately corroborated by empirical data, but with unexplained variability that is not uncommon in field surveys where gear biases, temporal biases, and scale biases prevent accurate characterizations. Our conceptual model distinguishes three types of conservation actions relevant to large agricultural floodplains: reforestation of large parcels and riparian zone conservation, in-channel interventions and connectivity preservation, and flow augmentation. Complete restoration of the floodplain may not be an acceptable option to the agriculture community. However, in most cases the application of even the most basic measures can support the return of sensitive aquatic species. We suggest that together these types of conservation actions can bring improved water properties to impacted reaches, higher reach biodiversity, more intolerant species, and more rheophilic fishes.
