We conducted a hearing investigation on self-support farming in Kosuge village, Kitatsuru District. Yamanashi Prefecture. In this paper, we described the overview of 'subsistence farming' in Motomura and the farming method and life styles of the villagers there in order to understand the problems of mountain villages. In the old days, the villagers here employed four types of farming methods : field-slash-and-burn-forest-meadow. Staple food in this village was taro and grains or coarse cereal gained through slash-and-burn farming. From 1782 to 1788, a great famine occurred.

This paper investigated the cause of abandoned farm land in hilly and mountainous area and proposed correspondence to cope with this problem. The progress of depopulation is also violent, and the population will be almost reduced by half from 1960 in fiscal year 1980. The farmland of the ratio of the abandoned cultivated land made a forest is also abundant 20% and in those. Through the investigation and the field survey focusing on the home pattern and the farmland condition, the generation factor of the abandoned cultivated land was analyzed.

The changes in the ownership structure were to be implemented by the Agricultural Property Agency of the State Treasury, which, under the Act of Law of 11 April 2003 on the structuring of agrarian system (i.e. The Journal of Laws of 2012, item 803, as amended), on 16 July 2003 became the Agricultural Property Agency with eleven local branch offices.

In a course of the research there was studied the historical path of the emergence of private property in the world and in what is now Belarus. The evolution of concepts of private property during the XIX - XX centuries was analyzed. Based on the history of private ownership of land, the provisions of Roman law, the need to raise interest of peasants in the effective management, it was shown a possible in the future way of the transfer of agricultural land to private ownership of peasants. The foregoing provisions are theoretical justification for these proposals.
