The purpose of this study is to show the administrative institutions and acts for the unused farmlands in hilly and mountainous areas. The Nagano City Agricultural Commitee surveyed the farmland used in 2013, and produced a survey in collaboration with the members of their committee as well as other farmers. In this survey, it was shown that almost all the unused farmlands were kept as forests and thus, couldn't be cultivated. Before the 1970s, silk was produced in Nagano City, and so almost all the unused farmlands were used for mulberry production which supported the silk industry.

In a course of the research there was studied identification of problems and directions of improvement of agrarian land use. The research was realized in the conditions of the Republic of Belarus. The possibility of practical application of results of estimation of production potential of agricultural organizations and ecological state of territory for economically-functional zoning of agricultural lands was examined.
