The solution of preserving and restoring the soil fertility problem of agricultural lands in the process of economic activity is one of the main tasks in achieving global food security. Implementation of a complex of soil protection measures, as a rule, ensures the preservation and even growth of soil fertility. Therefore, the purpose of the article is to determine the economic efficiency of introducing soil protection measures in the use of agricultural land. For this purpose, the following tasks were set and solved: the analysis of the current state and trends of the land resources use in agriculture; to investigate the tendencies of carrying out measures on preservation of soil fertility and prevention of its degradation; to substantiate scientific and methodical estimation principles of economic efficiency of introduction of soil protection measures in the conditions of Ukraine. The following basic methods were used to solve the research objectives: monographic analysis – when developing scientific publications on environmentally friendly use of agricultural land; comparative and statistical analysis – in studying the dynamics of the structure of the land fund of Ukraine by main types of land and economic activity; system-structural analysis and grouping – in the study of the nature and content of ecological and economic consequences of soil degradation, as well as approaches to assessing the economic effectiveness of soil protection measures; economic analysis and calculation of relative indicators – to evaluate the economic efficiency of soil protection measures in the process of agricultural land use; abstract-logical method − for theoretical generalizations and conclusions formation, etc. Established that soil degradation is now one of the most important industrial and environmental issues, which is the main reason for the inability to achieve high rates of environmental and economic efficiency of land use in the future. It was also substantiated scientific and methodical approach to determining the economic efficiency of soil conservation measures in the current market conditions, which is based on the additional income that is received as a result of increase crop yields on protected lands. It is established that effective protection of soils from degradation is possible with the systematic implementation of soil protection measures complex, developed taking into account the specific natural and economic conditions of each region or agricultural enterprise. The priority directions of realization measures on land protection are given.

The issues of environmental protection, prevention of degradation and reclamation of damaged land are currently very significant and relevant. As damaged land has been observed the land where low productivity and low economic potential have arisen and natural productivity of ecosystems is changed due to human-caused activities. The nature and extent of the violation depends on the type, depth and duration of anthropogenic impact, on adopted system of work organization and the conditions of the environment. Black soil dominates in the soil cover in Samara region; therefore there has been developed agricultural production. However there are located large oilfields and gas fields, which are under active exploitation and reduction of vegetation, dumping technological sites, laying trenches for pipelines, etc. have been noticed, which leads to formation of technogenic soils, damaged land cover, loss of soil fertility and land use type change. There special restoration measure − reclamation should be putted into practice on the territory of all categories of land, but especially on agricultural land. The aim of the article is to study the situation with damaged agricultural land in Samara region of Russia and to develop scientifically based proposals for regeneration of its fertility after reclamation measures. The problems of pollution of agricultural land in the region have been investigated, main sources and types of pollution have been analysed, as well as legal, methodological and environmental protection documents on land reclamation have been studied. The peculiarities of reclamation of land on federal, municipal and property level have been considered. The article presents measures for reclamation of the land on the example of natural monopolies in the territory of the Samara region.

The zones of ecological trouble cover about 15% of the territory of Russia, where the main production capacities and the most productive agricultural lands are concentrated. The Samara region is characterized by a distinct natural zonality from a typical forest-steppe in the North with a forest cover close to 30%, to an open dry steppe in the South with a natural forest cover of only 0.1...0.2%. The article presents an analysis of land use in the Samara region on the example of the Borsky municipal district. Research methods include environmental analysis and statistical data analysis.The article presents an analysis of the land use of the Borskiy municipal district. During zoning, the territory of the district is divided into the northern, central and southern parts. Assessment of environmental and economic parameters showed heterogeneity of the territory and the need for detailed consideration of climatic, soil, economic conditions in the design of landscape optimization systems, even in the municipal area. In general, the district's land fund experiences an average anthropogenic load, the ecological stability of the territory as a whole is characterized as unstable stable. In comparison with other areas of the Central MES, the municipal Borskiy district belongs to the category with an average ecological intensity with a stabilization index of 0.59 units due to the beneficial influence of the Buzuluksky area.

Starting in 2016, the process of financial decentralization began in Ukraine, in which local governments of lower levels (rural, urban, city councils and united territorial communities) were entitled to independently establish on their territory the rates of many local taxes and fees credited to community budgets. In particular, tax legislation of Ukraine allows local governments to vary land tax rates in the range from 0.1 to 3% of the normative monetary valuation of land, as well as to differentiate tax rates depending on the type of intended use of land plots. The study created a database and analysed the spatial heterogeneity of land tax rates in more than 9.6 thousand communities. It is shown how the level of tax burden on land owners and land users, established by local self-government bodies, correlates with the economic development of the regions, as well as the normative monetary valuation of land, which is used in Ukraine as a tax base. The problems of taxation of real estate, which arise at the separate collection of land tax and tax for real property other than land, are considered, as well as suggestions on the necessity of introduction of tax zoning of territories in Ukraine, which will allow to further differentiate the rates of taxes on the property and provide more flexible and adaptive taxation of real estate.
