Vashchyk, S., Lviv National Agrarian Univ. (Ukraine) | Kolodiy, P., Lviv National Agrarian Univ. (Ukraine)
In the Western region of Ukraine, melioration is both of economic and social importance. The area of reclaimed lands constitutes 2.2 million ha or 24 % of the total agricultural lands in the region. Thus, melioration is of great importance for social-economic development of agro-industrial complex of the territory. Under conditions of the land reform in Ukraine, reclaimed lands were subjected to sharing and privatization causing a negative impact on efficiency of its utilization and technical conditions of the reclaimed land infrastructure. The aim of the research is to analyze conditions and suggest practical recommendations as to rise of productivity of reclaimed lands, peculiarities of land organization on privatized reclaimed areas, consolidation of shared lands within the boundaries of acting drainage systems. Timeliness of the research is connected with the issues of improvement of agricultural utilization and protection of drained lands of the region. The authors used economic-statistical, monographic and logistic methods in the research. The example of Lviv region was used to analyse conditions and problems of reclaimed lands of western regions of Ukraine under conditions of land relations’ transformation. It is mentioned that only 70 % of drained areas feature satisfactory water-air regime of soil for cultivation of agricultural crops. Prospects of an increase of their utilization efficiency are connected with reconstruction of the systems consolidating common technological melioration complexes, support of both-side regulation of soil humidity.

The search of effective methods of agricultural land protection from soil erosion under conditions of land relations’ reform in Ukraine is a complex ecological and economic issue requiring a system approach to its solution, adequate organizational and economic support and scientific argumentation. The topicality of the research is based on the importance of the problem of arable land protection from soil erosion, and its solution is related to ecologically safe land utilization keeping to the principles of balanced development of land management. The aim of the research is to develop scientific basis for the recommendations how to improve the system of erosion-safe agricultural land management under conditions of reforming land relations in Ukraine. The article presents scientific fundamentals of organization of erosion-safe land management in the context of the balanced development of nature management, analyses conditions of utilization and protection of land in erosion-unsafe landscapes; develop scientifically grounded recommendations as to improvement of a system of erosion-safe agricultural land management at a local level. In the process of the investigation a combination of methods were used: monographic, induction and deduction methods, system analysis, cartographic, experimental projecting. A contour organization of the territory is recommended to apply to protect arable land from soil erosion. Reimbursement of money payments and tax privileges can motivate landowners and land users to introduce anti-erosion measures. It is required to consider use value and non-use value of land resources in the process of their estimation for land payments.

Tsvyakh, O., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine) | Openko, I., National Univ. of Life and Environmental Sciences of Ukraine, Kiev (Ukraine)
Land as a production factor occupies a special position in the economic activities of the urban population. Land resources in big cities are not only territorial basis for placing industrial and production structures, but also a space for urban life in general. However, to assess the effectiveness of urban land use, primarily the ecological and economic potential of the use of the urban land resources should be determined aimed at sustainable development of urban agglomerations (Volodchenkov, 2010). The rapid pace of development of large cities in the world and an increase of their impact on the environment and society is accompanied by the set of economic, ecological and social problems which significantly influence the development of settlements in general (Stolʹberh, 2000; Onyshchuk, 2001). However, the process of urbanization as a result of rapid scientific and technological revolution requires large areas for deployment of large scale production facilities and urban settlements in the conditions of natural resource management (Kontorovich, Rivkin, 1986).

2017
Savchuk, S., Lviv Polytechnic National Univ. (Ukraine) | Kalynych, I., Uzhhorod National Univ. (Ukraine)
The national geodetic infrastructure of Ukraine has developed rapidly into Ukrainian Coordinate Reference System UCS – 2000, a fully GNSS compatible coordinate reference system, which is realised through networks of active GNSS stations. They provide data for post processing and streamed raw data for real-time network (RTN) solutions. The RTN raw data are currently being used by both Trimble (ZAKPOS Network), Leica Geosystems (System Solutions Network) and Topcon (TNT - TPI Network) to provide independent RTN solutions. This study is the first in the public domain to evaluate the performance of RTN services in Ukraine and it is intended to provide guideline information for geo-spatial practitioners. Based on collecting RTN data at five locations and using standard observing and processing methods, an accuracy of 25 mm ±10 mm with respect to 2D coordinates and 34 mm ±14 mm with respect to the heights was achieved. The three systems were shown to be generally comparable although some initialization problems were experienced. The result has revealed expected ~2-5 cm (95%) precision for the horizontal and vertical components; however, large horizontal and vertical biases were observed, which can be as high as 8 cm.

2015
Stoiko, N., Lviv National Agrarian Univ. (Ukraine) | Perun, N., Lviv National Agrarian Univ. (Ukraine)
Solution of ecological problems is an urgent and extremely important task at the present stage of social economic development of Ukraine. Unreasonably high degree of economic (mostly agricultural) reclaiming of area causes spreading and intensification of degradation processes in ecosystems. Conservation of lands, including the one carried out by means of foresting of degraded lands, is the principal way to renature environment. The article concerns an issue of land conservation in the context of ecosystem services of forests. The aim of the article is to assess the economic value of ecosystem services of forests in case of land conservation. To achieve the aim the authors developed a classification system of ecosystem services of forests according to their functional purposes; provide the calculation of prospective economic value of ecosystem services while foresting of a land plot with heavy eroded soil. The research was carried out using system, monographic and abstract-logical methods. The integral evaluation of prospective ecosystem services of forest in case of foresting of degraded land resulted in: minimum – 5. 07 thousand UAH per 1 ha in a year, maximum – 35. 91 thousand UAH per 1 ha in a year. The calculation of economic costs of ecosystem services should be applied for assessment of the economic value from protection of nature-protective areas as well as implementation of economic stimulation for land conservation.

The current situation in land leasing in Ukraine is analysed, when a tenant of a land parcel with immovable property is sold in part, which causes the following controversy: the land parcel in someone’s lease has buildings or constructions owned by another physical or legal person (other than the tenant). The interested party wastes a lot of time on resolving this controversial situation with the existing procedures in Ukraine. This problem is not always solved professionally because of the lack of sellers’ and buyers’ knowledge of specific features of land management and geodesy. Three main variants of mutual location of the seller’s and the buyer’s buildings and constructions are defined, which determines the possibility of dividing a land parcel. Recommendations on the improvement of the procedure and normative legal acts of Ukraine concerning the issue are developed, aimed at significant acceleration of signing and registering new lease agreements.

From a theoretical point of view, the authors have grounded a new paradigm of theoretical planning of land management, which is based on space definition of a complex of factors of rational use of the existing land resources in correlation of interests of subjects-land-users and corresponding land relations in the terms of support of a balanced social-ecologic-economic environment. From a methodological point of view, the authors have proposed a set of methodic approaches as to determination of mechanisms of arrangement of the process of territorial planning in land management according to institutional fundamentals of land relations harmonization at different space levels of management. It is proposed to consider planning of land use as an obligatory and logically inevitable stage of the process of territorial space management that is determined as a primary link, because it specifies aims of the management. It is proved that effective territorial management of land resources and land-use is caused by its territorial planning, which determines the aims of an object development and activity of a managerial subject. A regional link of management should secure the supply of appropriate conditions for living standards of population, effective utilization of territorial resources and development of mutually favorable inter-regional relations. Implementation of efficient regional policy on the basis of market mechanisms requires further improvement of institutional fundamentals.
