Without cadastral information, it is difficult to make any decisions about land. But in order for the system of state land cadastre to work effectively, it is necessary that the information in it is up-to-date, complete and reliable. The article analyses in detail the existing legislative and regulatory acts and draws conclusions from the methodological principles of keeping the state land cadastre in the part concerning the consideration of factors of influence on the quality of land accounting. The status of agricultural land use was monitored and land conservation measures recommended. The authors have analysed in detail the public information on the soil cover of Ukraine, which is displayed on the Public Cadastral Map of Ukraine. The necessity of enrichment of the cadastre with new information and indicators is investigated, which allows to solve a wider range of problems regarding the use of land as a spatial basis and the purpose of development of the multifunctional cadastre.

Zudilin, S., Samara State Agricultural Academy (Russian Federation) | Konakova, A., Samara State Agricultural Academy (Russian Federation)
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.

With growing importance of the global economy, one of the basic natural resources − intensity of land use − is also increasing, which often is the cause of land degradation processes. The causes and manifestations of brownfields are diverse, and their elimination is the first prerequisite for the sustainable use of land resources and development of each region. Improvement, maximal and efficient engagement in economic activity of brownfields is one of the key challenges for sustainable resource use that makes significant contribution to regional development. The reuse of brownfields has significant impact on sustainable development as it meets all three of its objectives: improving the economy, improving social cohesion and the environment. The aim of the article is on the basis of special literature examples to examine issues of sustainable development, evaluation and restoration of brownfields, transformation of brownfields into recreational areas, as well as further use of brownfields in cities and rural areas.

Gudritiene, D., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania);Kaunas Forestry and Environmental Engineering Univ. of Applied Sciences (Lithuania) | Abalikstiene, E., Kaunas Forestry and Environmental Engineering Univ. of Applied Sciences (Lithuania)
The systemized and methodically arranged according to the principles of geographic information systems set of the most important objects of Lithuanian territory’s geodetic base and topographic databases (GDR10LT) is collected and kept in data storage and covers the whole territory of Lithuania. The purpose of the georeferential base GDR10LT at the scale 1:10 000 is to collect, keep, use, renew and provide data to users. The literature analysis shows that the majority of authors presented studies about data composition and application but they did not analyse their reliability. The aim of the research was to revise the chosen territory of the georeferential base map by the field method and to determine the discrepancies between the situation in the area and in the map as well as the reasons of such discrepancies. It was necessary to verify the data reliability and outdated map information due to changes of the situation. The field research was conducted in three different areas, and the data was processed using tools provided by www.zis.lt. Statistical data analysis was performed using Microsoft Excel software. The object of the research was information depicted in georeferential base map (GDR10LT) of the chosen territories. The following research methods were used: literature analysis, analysis of cartography material, collation of field data, statistical data processing, and interviews. The conclusion can be made that GDR10LT data are reliable; two mistakes were found in the plot of 6407.5 hectares: a navigational obstacle and 800 metres of asphalt cover were not marked. Other determined discrepancies covered the territory of 17.46 hectares. The outdated map information was found. The marking of settlements generally were mismatched because of many new buildings in the area that were not mapped. Therefore GDR10LT should be updated more often in accordance with ORT10LT data.

Development and management of green area systems is important to both the environment and a person. It bears social, economic, and ecological significance. This system must comply with principles of sustainable spatial development. Therefore, well-developed systems of green areas must become the basic aim of all cities. Marijampolė, the seventh biggest city of Lithuania was selected as the research object. In the article the system of Marijampolė city green areas is analysed. Two surveys, which included questionnaires, were conducted, i.e. city inhabitants and territory-planning and management specialists were interviewed. It was identified that the system of Marijampolė green areas is not balanced and there are enough green areas only in part. However, the current parks, squares and other green spaces do not ensure full-fledged citizens’ life. Marijampolė lacks equipped, applied to various activities local green areas for different age groups of the community, the development and maintenance of which must primarily be the inhabitants’ concern.

Scientific and technological progress does not bypass any industry, including the agro-industrial complex. With the development of technologies for remote sensing of the Earth, obtaining relevant information about the availability of objects of their condition and use, the introduction of advanced technologies and modern equipment in agriculture, the automation of land management processes, including land management, becomes urgent. Analysis of existing geoinformation systems allows us to conclude that the task of geoinformation support of land management in full in the form of an independent geoinformation system is absent. At the same time, in the considered complexes, there is a solution to certain land management tasks, such as the creation of digital maps of fields, anti-erosion organization of the territory, the construction of digital relief models, correction of soil maps based on satellite images, etc. The purpose of the article is to analyze information sources in the field of geoinformation support of the land management process in the Republic of Belarus, to identify tasks for the development of a comprehensive methodology for the implementation of digital land management in the Republic of Belarus.

The construction sector is linked to the general development of a country. There is a lot of data scattered and not properly explored in relation to the buildings constructed. However, if these scattered data on the behaviour of the real estate market are organized, combined with knowledge of civil engineering, this merger of information can mitigate some evaluation problems, especially those that are overvalued for unknown or dubious reasons. Thus, there is a need for models capable of working with limited data to analyse the causal relationships between explanatory variables and sales prices and, from there, predict property values. The purpose of this article is the innovative use of simple building inspection strategies to predict the market price for residential apartments. For this, 19 samples of residential apartments are used in the city of Niterói, Rio de Janeiro, Brazil, in February 2021. The methodology uses the results of the survey of civil engineering and converts them into heuristic terms predicting the price of the property. With this, the imprecision, uncertainty, and subjectivity of human expression combined with the knowledge of civil engineering result in a plausible solution and easy application in the market. Finally, the use of fuzzy logic in the evaluation of properties is an adequate unconventional method, in addition to avoiding repetition in regression coefficients in binary logic. To check the reliability of the method, the comparison between the market values of the samples and the values predicted by the fuzzy logic is used. The result according to the mean absolute percentage error (MAPE) can be interpreted as a good result (7%).

Having analysed research results, it is ensured that sustainable land use of US agricultural lands for the support to farmers to improve the efficiency of their major activities and adherence to the principles of soil protection and rational land use in farms. An analysis of the American experience allows us to make conclusions that the success of the process of improving land relations depends on the level of their scientific validity, the degree of balance of government regulation and the degree of coordination of participants’ interests in transformations and land market transactions. Land lease in the United States of America as one of the economic methods of land use regulation has been analysed in the article. It has been established that long-term lease relations are beneficial for both parties concerning soil improvement and pollution control in case of clear legislation. Having analysed foreign experience, the main measures of land use rationalization in the USA, which people can use in Ukraine, have been proposed. It is also possible to implement the US experience in actively controlling the ecological condition, intended use and other quality characteristics of agricultural land to improve regulation of land use in Ukraine. After analysing the measures for land protection in the United States, taking into account the considered and researched American experience of agricultural land use, ways to improve the existing system of use and protection of agricultural land in Ukraine are proposed.

The aim of the article is to analyse the land use of selected areas and its impact on the ecological condition of the area. 3 (Ignalina, Molėtai and Zarasai) from 15 districts (which are characterized by considerable forest cover and exceptional recreational characteristics) of Lithuania were selected as the object of research. The largest part of the area of these districts (44–57%) consists of agricultural areas; a slightly smaller area (32–42%) is occupied by forests and other natural areas. Artificial covers occupy from 8 to 11 percent of the total area of districts. Analysing the change of these land cover areas over a period of 12 years, a practically stable (4-6%) decrease of agricultural areas and growth of forests and other natural areas (3–5%) as well as artificial covers (1%) in all three municipalities are observed. Taking into account the prevailing land cover structure in the districts in 2018, the estimated degree of polarization of all districts/ecological stability indicator of the area exceeded 0.67, i.e., areas have been found to be ecologically stable. However, after assessing the ecological stability of the surveyed areas using a multi-criteria analysis method and introducing more criteria influencing the ecological condition of the area, not only the land cover structure, it was found that the ecological condition of Molėtai district is still the worst according to the ranking indicators, while that of Zarasai and Ignalina districts is very similar. Such a negative multi-criteria assessment of the ecological condition of Molėtai district was influenced by all criteria: lower area of protected and natural territories, forests in the district, higher population density, road length, area of artificial covers and emissions (carbon monoxides, nitrogen oxides, etc.) quantity. Meanwhile, when assessing the ecological condition of Ignalina district, 4 criteria were favourable, namely: relatively low population density, road length, and lower emissions of gases and liquids, carbon monoxide, and for Zarasai district 7 criteria: higher areas of protected territories, forests and other natural, agricultural areas as well as artificial cover areas and lower population density, emissions of nitrogen oxides, gaseous and liquid substances. The results of the study unambiguously revealed that the ecological stability of the territory is influenced not only by the land use structure, but also by other environmental elements related to the area, therefore for full sustainable development, it is necessary to responsibly assess all possible factors influencing the ecological condition of the area.
