The analysis of the current situation of Aukštadvaris Regional Park and ecological farming (RP), which is in southeastern Lithuania, is presented in the article. The Paluknys subdistrict was chosen for the comparison of the use of ecological farming in the regional park. Ecological farming is relevant to protected areas. The aim of the study was to perform the analysis of farms applying organic farming measures as well as the analysis of the change of their areas in Aukštadvaris regional park (RP). Comparative, analytical as well as statistical and logical analysis methods were used for the investigation. The object of the investigation - the farms of Aukštadvaris Regional Park. The study was carried out to determine how many farms, forming the territory of the regional parks, are managed according to the principles of organic farming. The change of the abovementioned farming area for 2011-2013 is analysed as well. Paluknys subdistrict, not incorporated into the territory of regional parks, was chosen for the comparative analysis. The analysis of the 2011-2013 period showed that the number of organic farms increased by 1.5 times in Aukštadvaris RP over the period of 2011-2013, and the area has increased by 187.36 ha. The percentage calculations revealed that in 2013 the area of farms applying organic farming measures in Aukštadvaris RP made up 18.89 per cent of the total area declared, the number of farms - 6.61 per cent.

The result of the long existence of legal restrictions on the agricultural land market in Ukraine was the formation of a specific leasehold system of land use. Agricultural enterprises and farms do not have land owned. Instead, the peasants who became owners of land during the distribution of collective farms, mostly do not process these parcels of land on their own, but also deprived of the right to alienate them (to sell, give, change). The study shows the development of leased land use of agricultural enterprises in Ukraine, which currently covers 16.8 million hectares of private land and about 1 million hectares of state-owned land. Since 2003, the civil law of Ukraine permitted to apply not only the lease of agricultural land, but also the emphyteusis right (the alienated right to use someone’s land for agricultural purposes), the process of transformation of lease into emphyteusis was started, especially in large agricultural holdings. The main advantages of emphyteusis as a substantive law and its attractiveness for agribusiness are considered. The suggestions on improving the legal regulation of land use under conditions of emphyteusis are given.
