2019
Shevchenko, O., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
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 analysis results of common terms in land management and their interpretations in normative-legal acts of Ukraine are presented. It have been established collisions and significant differences in the wording of even such common terms as a land parcel, a boundary of land parcel, a size of land parcel, etc. The purpose of the study is to identify collisions and contradictions of some key terms used in land surveying and geodetic works, as well as development of concrete proposals for improving and perfection the relevant terms. For this purpose, the following tasks were set and solved: analysis of regulatory legal acts of Ukraine concerning the conceptual apparatus of land management, systematization and generalization of substantiation results of the relevant terms correction need, development of proposals taking into account works content on land management and geodetic works for information provision of the State Land Cadastre. In the course of the study, the comparative method of analysis and the systematization of inconsistencies in the current normative legal acts of Ukraine regarding the terms and their interpretation are used. During the proposals development, known approaches "from general to partial" and vice versa were used. The established disadvantages do not allow unambiguously interpreting and performing such important work as geodetic setting or restoration of the land parcels boundaries, resolution of land disputes between adjacent users of land parcels. Completed summaries of content and wording of the relevant terms justify a need for correction of the terms and additions to their definitions. It was set the features of each term. As a result of integrated approach to solution of the existing problem and systematization of established differences, the general wording and detailed specification of the analyzed terms interpretations are proposed. Knowledge of technological stages for geodetic and land management works provided an opportunity to improve the geodetic information support of the State Land Cadastre. The proposals for correction of the studied terms eliminate existing contradictions, provide an unambiguous interpretation of land management terminology, which leads to the exact execution of geodetic and land management works, and, accordingly, obtaining reliable information for the State Land Cadastre.

The article defines that the land inventory allows to form land plots of state and communal property, to fill the State Land Cadastre with information about objects and subjects of land relations and to eliminate existing errors. The aim of the article is to improve the procedure of conducting the land inventory in Ukraine, taking into account modern technologies within the current regulatory framework. The methodology of land inventory using modern technologies has been developed, which includes the following components: surveying of the inventory object, topographic and geodetic works, vectorization of its territory using remote sensing data, project works, creation of a consolidated inventory plan, development of technical documentation, its state expertise, adjustment and approval, entering data into the State Land Cadastre. It is established that an effective method of implementation of topographic and geodetic works during updating of the cartographic materials is a combined method, which includes the use of aerial images with simultaneous geodetic surveying of complex areas. The use of geoinformation technologies and remote sensing data is allowed to optimize the duration and frequency of land inventory. In particular, the classification of land should be performed in the attribute tables. Ways to solve problems of protection and rational use of the lands of the inventory object have been developed. They include registration of land plots without cadastral numbers; control of compliance of land and environmental legislation, taking into account the results of land inventory for updating statistical cadastral information and making changes of the State Land Cadastre data.

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.

Petrakovska, O., Kyiv National Univ. of Construction and Architecture (Ukraine) | Mykhalova M., Kyiv National Univ. of Construction and Architecture (Ukraine)
Land use regulation is one of the most important state tasks and is aimed to ensuring the sustainable development of settlements. One of the mechanisms to solve this task is land use limitations establishment by restricted the possibility to carry out some activities, on certain territories or separate land plots, which would lead to negative ecological and social consequences. Such activity is becoming more and more urgent in the face of increasing ecological problems. Land use limitations could be considering in different areas. On one hand, the feasibility of land use is governing by the methods of spatial planning, based on natural and anthropogenic conditions. On the other hand, land use limitations are the result of location of object is which could be either source of negative influence or the object is requiring being protected (mode-forming objects). The aim of the article is to determine the impact of land use limitations on the various components of society, taking into account the environmental, economic and social components of sustainable development. Environmental and socioeconomic impact of land use limitations formation on the example of limitations caused by the activity of a mode-forming object is described in the study. The results of the study illustrate that the establishment of limitations on the land use can solve mainly environmental and social problems.

For millennia, the geodesic industry has improved methods and technologies for obtaining information on the location of objects on the Earth's surface, whose key task has been to improve the accuracy and reliability of measurements. At the same time, in recent decades, the rapid development of positioning technologies based on satellite radio navigation systems has created prerequisites for a situation where the acceptable accuracy of determining the geodetic characteristics of real estate becomes quite affordable even when using non-specialized geodetic equipment, including personal mobile devices. The article shows that the error in determining the area of land for registration of rights to real estate has its own “costˮ, which depends on the value of real estate in the area of survey. By the example of model sites, it is shown that further improvement of the accuracy of engineering surveying to determine the spatial characteristics of real estate objects would be economically feasible only if the cost of geodetic surveys (including the cost of purchasing new geodetic equipment, payment for labour of specially trained engineers, additional technical services and etc.) will not exceed the “cost of errorˮ to determine the area of the site. Using the example of Ukraine, it is shown that the most accurate geodetic surveys (determining turning points of land borders with an accuracy of more than 0.02 m) are economically feasible only when the market value of a land plot exceeds USD 208 per square meter.

2018
Martyn, A., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
The key features of the blockchain databases, such as decentralization, distribution, security, and record of the history of all transactions, create significant prospects for their application in the field of cadastre and real estate registration activities, including creation of the global real estate cadastre infrastructure, which will be able to go beyond national legal systems and jurisdictions. The conceptual approach to registration of land plots as spatial objects using blockchain technology is proposed. The land plot should be considered as a combination of smart contracts between landowners, surveyors, appraisers, notaries and other persons. The subject of such contracts will be the description and establishment of spatial (plot boundaries, territorial zones, etc.) and other (property rights and encumbrances, monetary valuation, soil bonitet, etc.) characteristics of land plots. The classification of such smart contracts reliability is also presented.

2018
Ievsiukov, T., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
The main factors that influence the rational land use, conservation and protection of land resources are global ecological and food security, world's population growth, climate change, land acquisition by large world agricultural corporations etc. In this process a priority of attention is protection of the important agricultural lands (in Ukraine, these lands are called especially valuable lands - EVL). Besides, lands with highly productive soils, areas with undisturbed ecosystems, territories with objects of cultural heritage, natural therapeutic resources are a part of EVL. This paper focuses on new approaches to the legal protection of EVL in Ukraine. The special value of these lands in Ukraine is legalized and is means of their legal protection (Art. 150 of the Land Code of Ukraine). The main idea of this paper – studying of problems of legal protection of EVL and development of new approaches to their protection. These approaches will be based on introduction of economic regulators at withdrawal of EVL or change their intended use for needs that don't correspond to nature protection value. The reseach is based on case study method and statistical method. Approaches for cartographic modeling for assessment and mapping of EVL are offered. Results of this reseach are an obtaining of practical experience in the field of protection of EVL in Ukraine, development of suggestions for improving of an organizational and legal mechanism the use of EVL through their registration, monitoring, evaluation, development of their State Register. These measures can increase competitiveness of EVL, prevent Land-Grabbing and provide sustainable development of the rural territory.

2018
Tserklevich, A., Lviv Polytechnic National Univ. (Ukraine) | Khoptar, V., Lviv Polytechnic National Univ. (Ukraine)
The presence of a large number of territorial units with a high price of land determines the appropriate accuracy of their area determination in the short term. The widespread use of unmanned aerial vehicles (UAVs) is a modern geospatial mapping technology. Using an UAV equipped with appropriate devices for aerosurveying − such as, for example, the Trimble UX5 − is economically feasible in comparison with ground geodetic measurements, since the latter requires a lot of costs. Therefore, the main purpose of this study is to analyze accuracy estimation of land parcel area determination based on aero surveying materials using an unmanned aerial vehicle (UAV) in comparison with results of ground geodetic measurements using a total station. As a result, a comparison of detailed plan and an existing base of land parcel measurements with accuracy estimations have been made. Based on our analysis and experimental studies, we can state that the UAV allows more efficient data collection within the requirements of land management in comparison with ground geodetic measurements. The use of aero surveying materials for determination of land parcel areas has been proposed. The results of the study provide an opportunity to improve the reliability of land parcel data in the normative and methodological framework.

The article highlights the issue of accuracy of determining of the zones of restricted use of the territories along the transmission lines taking into account the magnetic field influence around the wires of transmission line during the passage of electric current. The procedure of establishing of such zones near transmission lines requires a clear substantiation of limits of physical parameters of the electric and magnetic fields` influence of transmission lines on human resources and environment that leads to the establishment of scientifically based boundaries of safe and rational management of land use. The authors` task was the substantiation of a mathematical expression that describes the relationship between the accuracy of determining the radius of dissemination of the magnetic field along the transmission lines and physical parameters of the magnetic field. As a result of the conducted research the formulas for determining the standard deviation (SD) of the radius of dissemination of the magnetic field were presented taking into account the value of magnetic induction, capacity, voltage and amperage that were inherent to the particular transmission line.
