2015
Parsova, V., Latvia Univ. of Agriculture, Jelgava (Latvia) | Cahrausa, I., Ministry of Environmental Protection and Regional Development, Riga (Latvia)
Land degradation is a topical issue not only in Latvia, but also in Europe. Even the real estate additional tax rate of 1.5% does not prevent agricultural land from overgrowing, and there is no other legal mechanism to control it. One of the mechanisms of prevention of land degradation process is reconstruction of drainage systems, change of worthless agricultural land (less than 25 points) to forest land or improvement and return of agricultural land (more than 25 points) to economic production. Although such actions require financial resources, there may be a variety of financial support programs, for example, the decrease of the real property tax rate (in case of afforestation).

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.

Jukneliene, D., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Valciukiene, J., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Atkoceviciene, V., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
The article presents the Lithuanian forest land change in the period of more than a hundred years. The causes leading to forest land use change are analysed in the article. The beginning of forestry in Lithuania can be traced back to Sigismund Augustus times starting from 1557, when Wallach reform was launched. However, over time forest land and its use evolved for a variety of political, social and economic factors. In 1795 the state-owned forests in Lithuania amounted to 35% of the total area of forests; other forests were owned by landlords, churches and kulak farms. Later forests were cut down quite rapidly, many of them burned down, but reforestation work was insignificant. The smallest forest coverage during the analysed period was in 1945, just 16.5%. Forests were thinned out, wastelands and waterlogged areas dominated. Later, albeit with different variations, the forest coverage of Lithuania increased and today forest area accounts for more than 34% of the total area of the country, the majority of which are private forests. More detailed characteristics of forest land use and user trends as well as their causes are presented in the article. It also looks at the possible prospects.

Valciukiene, J., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Atkoceviciene, V., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania) | Sudoniene, V., Aleksandras Stulginskis Univ., Akademija, Kauno reg. (Lithuania)
The article presents the analysis of the change of land users in the Republic of Lithuania during the period between 1919 and 1940. The main factor affecting the relationship of land and its use was the political changes in the country, whereas economic and social aspects had less influence. During the period between 1919 and 1939 the land reform of independent Lithuania not only strengthened the country's agriculture, but also laid the foundations for the entire nation-state, it was one of the most significant achievements of independence, a real agrarian revolution, which intensified the land use. The main goal of the land reform was to alienate and distribute the state land and the land of large estates to peasants and to complete distribution of village land into individual farmsteads. Landlords were left inalienable 80 hectares (later 150 ha) of land area. The land from the State Land Fund was distributed to volunteers and new settlers (the landless) peasants up to 8-10 ha, to estate workers and rural craftsmen – up to 1.5-2 ha, as well as to poor peasants, state enterprises, farms and forestries, etc.

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.
