For many centuries land relations in the territories of Latvia and Russia have been developed by different influences of different foreign forces. The comparison of orientation and dynamics of the land reform in countries with similar initial parameters allowed analyzing the impact of changes in property relations on activities of farms, their productivity, involved costs and the benefits. The main conclusion is that the land reforms in Latvia and in Russia were not the main objective of agricultural land use saving and development of agricultural enterprises.

The problem of abandoned agricultural land is relevant in Lithuania, particularly in the territories where poor soils are dominant. The aim of this research is to analyze the statistics of abandoned land in poor soil regions by different estimation methods. The abandoned land was registered for the purposes of the research. Areas might be determined by using statistical data and by applying the results of a distant research method. The initially obtained data showed large differences among the areas of abandoned land determined by different calculation methods, and this might cause a lot of problems, in particular when clarifying the validity of the land taxation. Therefore the initial data of the research concerning abandoned land should be essentially revised. The results of abandoned land accounting and evaluation (inventory) in each territory should be checked and confirmed by the committee of qualified specialists. The reasons of abandonment should be determined for each land plot, and further use of the plot should be determined. Plots of abandoned agricultural land should be estimated for each parcel of the private land and registered in the cadastre data as additional information for estimation of the land tax.

The analysis of the declared agricultural land and ecological farming situated in the Krekenava regional park (RP), which is situated in the Middle Lithuania, is presented in the article. The Naujamiestis subdistrict was chosen for the comparison of the use of agricultural lands and ecological farming in the regional park. In 2011, the total agricultural land and crop area declared in the Krekenava Regional Park was 8184.19 ha, i.e. by 317.89 ha or 3.74 percent less than in 2009. 371 family farms were declared, i.e. by 53 farms less in comparison with 2009. In 2009, the declared area of agricultural lands in Naujamiestis subdistrict covered 9877.66 ha and it made up 63.32 percent of the total subdistrict’s area. 359 farmers introduced declarations. The average area of the declared farms was 27.51 ha. In 2011, the declared area of the agricultural lands was 9851.33 ha i.e. smaller than 26.33 ha or 0.27 percent less than in 2009. The number of declared farmers in 2011 was 329, i.e. by 30 farms or 9.12 percent less than in 2009. Ecological farming is relevant to protected areas. The article analyzes the Krekenava RP and Naujamiestis subdistrict’s farms applying ecological farming tools. The analysis of the 2009- 2011 period showed that the declared areas in Krekenava RP have decreased, and the area of farms applying organic measures has increased by 81.69 hectares (nearly 2.5 times). The number of farmers applying organic farming measures in Naujamiestis subdistrict has increased twice and 12 farms i.e., 3.63 per cent of the declared ones had organic farms in 2011, the analyzed area was increased by 581.55 hectares or 3 times.

The latest land reform in Latvia has substantially altered the structure of use of farmland leading to a great number of very small and fragmented agricultural holdings, yet, in terms of occupied total area and UAA, medium size (10.0-50.0 ha) and slightly larger (more than 50.0 ha) land holdings dominate. In Latvia the number of agricultural holdings tends to decline. On the contrary, the average UAA per agricultural holding rose (by 66%), reaching 23.2 ha in 2010. One can conclude that positive structural changes take place in the agricultural industry – the number of small farms has declined and the number of and the area farmed by large marketoriented farms has risen, thus the difference between the sizes of land holdings that emerged during the land reform and the land areas farmed by agricultural holdings has increased.

Peculiarities of farming land usage in southern Lithuania are analyzed in the article. The analysis of archival data and cartographical material reflecting the structure of farming land in Marijampolė, Šakiai, Kazlų Rūda, Alytus, Lazdijai and Vilkaviškis municipalities was accomplished. Information was taken from yearbooks and archives of public institutions of the Republic of Lithuania and other sources as well. It was determined after analysis of collected information that usage and location of cultivated land greatly depend on the land’s productivity. The largest amount of undeclared farming land is in the districts where the land less favourable for farming is dominant. The analysis of the period of last 10 years has shown that the area of farming land decreased by 753 ha in Lazdijai district and by 194 ha in Vilkaviškis district, but increased by 5.5 ha in Alytus district on average per annum.

The main reason of land fragmentation in Latvia was the restitution of ownership rights to former landowners or their heirs, as well as the land acquisition by other persons in the process of the land reform. As a result the ownership structure was obtained which is not competitive in the aspect of production efficiency. Different instruments as land consolidation, land reallotment and others can be applied for the reduction of land fragmentation. The reduction of land fragmentation should play an essential role in the use of the land corresponding to the spatial development plans which determines perspective land use. Therefore the improvement of the ownership structure should be one of the stages of land use planning.

Land management and improvement of computer technologies in land use are one of the most important tasks of the state; their effective implementation is closely linked to the widespread implementation of modern achievements of information technology. The achievement of the maximum transparency of the processes is vital in the field of geo-information and spatial data resources during increasing the reliability and manageability of the infrastructure.

From the old times Lithuanian manors were the main centres of diplomacy, administration and culture. The applied land reforms, war and post-war periods and changing regimes altered the structures of the manors; their owners and users changed as well. The number of homesteads of manors and their territory highly decreased. During various periods of time more than 150 manors were present in the current territory of Panevėžys district municipality. The aim of the research is to analyse the land use of the least researched homesteads of former manors in 1923 and 2016. Six homesteads of former manors that are located in Panevėžys district have been analysed. The research has revealed that a great amount of small land lots aggravates the farming conditions and does not allow the rational land use. Certainly, this problem is solved partially by renting or selling the land to the owners of the adjacent land lots. Land consolidation would help to pass beneficial decisions for the land use. In the recent years, due to the initiatives of state institutions and individual people a fair part of homesteads of manors are being rebuilt and adjusted to the use of society.

The main peculiarities of land relations abroad are highlighted in the article. Basic principles of foreign experience of land use regarding market circulation of land, concentration of major land resources by right of ownership as well as the process and ways of reformation of land relations are generalized and systematized. Some peculiarities of lease relations, collection of rents and restrictions on title to land for foreigners are analysed. Some positive aspects are distinguished in order to use them in Ukraine. Some ways of improvement of land legislation in Ukraine are suggested taken into account foreign experience.

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).
