The paper emphasized the necessity of measures on struggle with swamping of agricultural and forest lands of the Western-Siberian Plain via cleaning of the hydrographic network close to bogs. This will provide timely discharge of excessive waters from wetlands, and will decrease the subsoil waters level. Advantages of this approach in comparison with the traditional drainage methods have been shown as well. To substantiate the proposed approach the original hydrological assessment of the swamping causes is being presented.

Purpose. The purpose of the article is to substantiate the author’s approach to solving the problemof coexistence of people’s, state, municipal and private property and to formulate propositions forimproving normative and legal regulation of ownership on natural objects.Methods. The research methodology consists of such methods of scientific cognition as systemand structural, comparative and legal, formal and legal, interpretation, deduction, induction,analysis, synthesis, etc.Results. The author has combined in the first part of the article the existing scientific approacheson understanding the rights of ownership of the people of Ukraine into two concepts and has calledthem the denial concept of people’s property and the recognition concept of people’s property. Theauthor has distinguished two main areas within each of them, where certain variations of themain idea of the concept correspond each of them. The author has placed a special attention onsubstantiating the non-viability of the denial concept of people’s property, since it contradictsthe current legislation and the theory of law. The author has argued that, contrary to the denialconcept of people’s property, the people of Ukraine are a legal category, a subject of law anda subject of the right of ownership; representative democracy does not deprive the people ofUkraine of the status of the holder of rights, assumptions about the inexpediency of the existenceof people’s property is questionable, and arbitrary interpretation of the Constitution of Ukraineand its figural understanding is inadmissible. The author believes that the existence of the denialconcept is due to both the problems of normative legal regulation and insufficiently seriousattitude and perception by the people as a source of power and a subject of law.The author has studied specific features and shortcomings of legal regulation of the right ofpeople’s ownership on natural objects and has formulated propositions for its improvement in thesecond part of the article. The author has substantiated the way to solve the problem of coexistenceof the people’s ownership on natural objects with other forms of ownership.Conclusions. The author has concluded that the objects of the right of ownership of the people arecertain categories of lands (including lands of nature reserve fund) and forests of the highest value,subsoil, waters, open air, are defined in the law as fauna and plants (growing on lands of people’sownership). They are set aside from the objects that may be owned by other entities, according to the criterion of value, significance and category of natural objects. However, their normativeand legal regulation needs to be improved, namely the conflicts, gaps and non-compliance withthe Constitution of Ukraine admitted in regulatory legal acts must be corrected. The provisions ofthe Articles 13–14 of the Constitution of Ukraine should be also brought into accord, since theirambiguity, possibility of double interpretation and inconsistency of presentation contradict therules of rule-making techniques, create obstacles to realize the rights and freedoms of citizens andcause different practices of application of regulations.

Upper groundwater level (verhovodka) is considered as one of the factors of soil waterlogging associated with both the natural features of the territory and anthropogenic impact. On the case of one of the watershed areas of the steppe, where many years of scientific research are being conducted to assess the minimization of agrotechnical methods of cultivation of agricultural crops, a soil-geomorphological profile 1 km long was studied on which 8 wells were drilled, to a depth of groundwater with water sampling for salinity and chemical composition. The results showed that there are no visual signs of gleying in the profile of chernozems, the groundwater level correlates with the daytime surface of the relief, and in the soil-ground layer at depths of 2.0-3.9 m there is a horizon of "chocolate" clay, which forms a local aquiclude. Sulphate-sodium composition of fresh waters potentially dangerous for the salinization of chernozems at a high level of GWL (ground water level). Verhovodka  is important to desalinating groundwater located above the confining layer, playing the role of a local factor of desalinization of the soil-ground layer of sediments.Since 2009, in the Kamennaya Steppe, according to the data of the main hydrogeological well No. 1, the GWL is constantly at a depth of over 7 m, which characterizes the beginning of the next natural-anthropogenic aridization. In conditions of a lack of surface moisture, no-till techniques should be recommended as a factor in reducing evaporation and moisture accumulation in the steppe chernozems.

The article is dedicated to definition of the tendency to change and pattern of formation of the chemical regime of underground waters in the Turyanchay-Girdimanchay interfluve in the Shirvan steppe, Azerbaijan as a result of anthropogenic activity. The subsoil waters studied are spread in the zone between the Turyanchay and Girdimanchay rivers. From 1930 to 2019 based on analysis of the observation of the chemical regime of subsoil waters, the natural regime of the groundwaters in the studied area strongly changed as a result of irrigation and construction works. In 1930 the average mineralization degree of subsoil waters was 26.8 gram/liter in the zone. The level of subsoil waters approaches the surface and is exposed to strong evaporation as a result of irrigation and filtration of waters from irrigation channels. Consequently, the mineralization rate of subsoil waters increased and mass secondary salinization process occurred in the irrigated lands. The average mineralization degree of subsoil waters was 33.6–34.5 gram/liter in the research zone in the 1960s-1970s. Collector-drainage networks were built and basic washing of soils is carried out in order the prevent secondary salinization and regulate the level of subsoil waters. After the 1970s the mineralization rate of subsoil waters began to decrease due to basic washing, intensive irrigation and the activity of the collector-drainage network.The average mineralization degree decreased to 15.1 gram/liter. The mineralization degree of the water in the Main Shirvan Collector which takes subsoil waters formed in the zone with 253,000 hectares and which discaharges them into the Caspian Sea decreased more than 3 times in comparison with 1995. At present the mineralization degree of collector water is 1.8–2.5 gram/liter while its mineralization degree was 8.81 gram/liter in 1995. Formation of the process in a favourable direction enchances the potential of using collector water for irrigation, technical and other purposes and creates a basis for elimination of water deficiency in drought years. The research shows that anthropogenic activity mainly plays an important role in formation of the chemical regime of subsoil waters.
