The article presents the analysis of the current situation of the damaged land in Kaunas County. The methods of comparative, analytical as well as statistical and logical analysis were used for the investigation. The aim of the investigation is to carry out the analysis of the damaged land area in Kaunas County during the period between 2005 and 2017. The object of the investigation is Kaunas County damaged land. The study found that the number of affected areas in the county is 409. Because the damaged areas consist of mineral quarries and territories occupied by dumps, the article contains the description and condition of these areas. By 2009, there were 98 landfills in Kaunas County. Kaunas municipal waste management region comprises 6 municipalities; 58 old landfills and dumps were shut down, at present two regional non-hazardous waste landfills have been arranged. In 2017, the damaged land occupied 3,447.36 hectares and amounted to 14.15 percent of all Lithuanian damaged land and accounted for 0.43 percent of the county's area. During the period between 2005 and 2017 the damaged land area in Kaunas County increased by 236.48 hectares or 6.86 percent. The analysis of the damaged land area of the municipalities situated in the Kaunas County showed that the largest of these areas during the period between 2005 and 2017 was in Kaunas district municipality.

Land consolidation – an important stage of agricultural and rural development. This is a significant land use planning process, when private, municipal and state land parcels located in rural areas are redistributed in a complex way, their boundaries and location are changed by the prepared land consolidation project of a certain area. Recently, there has been a lot of talk about the benefits of land consolidation to farm structure and productivity, restructuring of rural areas and development, but there is not enough emphasis on the benefits of our environment, landscape and biodiversity. Experience of European countries shows that the land consolidation projects can be useful not only for farmers, but also for our environment and its individual components. The article gives an overview of not only the positive aspects of environmental preservation. The fact that the land consolidation projects can bring negative results (i.e. that they are implemented without regard to the sustainable transformation of the territory) is noted as well.

The article analyses the changes of agricultural production development and the demand of rural planning in the post-reform period. The main aim of the research is to identify the problems of land use and the formation of farms as the territorial-production structures in Lithuania as well as to analyse the possibilities of finding solutions to them. Tendencies of the decrease of the number of rural residents and farms were determined, the regulation of which is possible by improving working and living conditions in rural areas by means of public support measures. In order to form land holdings of rational farms, to coordinate the residential construction, farmlands and the local road network, to preserve efficient agricultural land, it is suggested preparing the documents of land management planning. The implementation of these documents is associated with the regulation of the land use provided for by legislation, formation of cultural landscape, as well as with the EU and public support for the development of production of viable farms and environmental protection. It is recommended to supplement the rules of the preparation of documents of land management planning with methodological requirements for the arrangement of land parcels and for their conversion into other agricultural areas.

Geoportal.lt is a Lithuanian state information system whose scope is to allow all data users to freely access geographic data, maps and e-services. The portal also allows drawing relief altitude profile and set the altitude of point on location. It is performed by applying the tool “Set altitude of point on location”. It is one of the newest tools of geoportal.lt website, whose accuracy has not been analysed, and which, according to the information provided by GIS Centre, complies with the requirements set for 1:50000 scale maps. This tool is selected as an object of research, while the aim of the research is to analyse the accuracy of data provided by Lithuanian spatial information portal tool “Set altitude of point on location” in case of different land covers. The following methods of investigation have been employed: literary analysis; the analysis of cartographic material; field measurements and data processing; comparative analysis of data. The data is processed using Geomap and Microsoft Excel programmes. After the analysis has been carried out, it was established that the most common errors in all types of land covers are from 0.5 m to 1.5 m. Such errors comprise 70 per cent in forest areas, 35 per cent in built-up territory, and 53 per cent in thin land cover. Taking into consideration that the website geoportal.lt operates on the basis of orthographic map whose accuracy is 1 meter and the discussed tool shows the altitude of the nearest known point, it can be stated that the obtained presumptions are permissible. To summarise the obtained data, the tool is reliable. The reliability of the data is 91 per cent in thin land cover, 86 per cent in forest area, 75 per cent in built-up area. To compare it with topographic maps of analogous format, where the errors of altitudes may reach up to 10 meters, the tool is reliable even in case of major errors.

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.

Declaration data of farming land and crop are analyzed in the article. Ukmergė district is chosen for the more detailed analysis. Statistical data of farmers and other land users are analyzed in the article; the declaration data of farming land and crop are analyzed and mathematical statistical dependence between the declared area and soil productivity index is determined. The results show that there are 2,506 registered farms in Ukmergė district and they manage the area of 18,430.07 hectares. The average parcel size amount to 7.35 ha. The number of farming persons in Ukmergė district as well as in Lithuania have considerably decreased during 7 years period. In 2014, the number of farming persons was by 38.12 percent smaller in Ukmergė district and by 41.24 percent in the whole territory of Lithuania compared to 2007. The comparison of the declaration data of 2011 with the data of 2014 shows that the declared area of farming land and crop in Ukmergė district has increased by 2.46 percent although the number of received applications has decreased by 22.2 percent. During the period of 2011– 2014 the majority of assessed applications were received in 2013, i.e., 99.04 percent of all applications received that year. It shows that the size of land parcels has increased. Cereal crops (oat, wheat, triticale, barley, rye, buckwheat and corn) composed the major part of the declared areas in Ukmergė district in 2013-2014 (48.84 percent of all declared crops in 2013 and 53.79 percent in 2014). The analysed agricultural holding “Egvila” during 2011–2014 period declared the area of approximately 272 hectares annually. This company grows white clover for seed, timothy for seed and cumin. Direct payments are received for all land areas. The analysis shows that farmers generally declared their own land. The analysis of the declared land distribution in Ukmergė district by land property right shows that 75 percent of the declared land are private and the remaining 25 percent are leased either from the state or from natural persons.

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.

Land cover objects are reflected in a set of georeferential data and are constantly changing. These changes can be accurately examined by computer and interactive information systems. One of the main advantages of computer information systems is the fact that their maps can be constantly improved and updated. The update of georeferential data was conducted in a selected area using the ArcGIS software. After the analysis of the Lithuanian land cover data, the area meeting the following criteria was selected: a diverse landscape, the abundance of different objects (built-up areas, forests, bodies of water), an adjacent city and good access to major metropolitan areas. The article presents the updated georeferential data and tracks changes in the updated data of built-up areas, areas overgrown with trees and shrubs, dams, swimming pools, lakes, ponds and roads in the selected area within the period from 2008 to 2015. The results revealed that changes occurred in all analysed layers. It proves that land cover objects are constantly changing. The greatest change was observed in the data of built-up areas. In comparison with 2008, in 2015 even 41% of built-up areas was changed (i.e. the old boundaries were revised, new and defunct built-up areas were discovered), 125 new areas have overgrown with trees and bushes and 46 changes were observed in ponds and pools.
