Japan's forest industry operates in mountainous regions rather than hilly areas. The forest road density is also low, and it is not easy to develop new roads and maintain them. Therefore, the work of moving about and transporting heavy loads over irregular mountain forest terrain far from roads is still hard labor performed by humans. Even today, a little technical development has been done to assist in this work.

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.

This study attempts to confirm the differences in carbon sink according to each type of land use by using the biotope map and reviewing carbon sink considering topography, and comparing those before-and-after topographic correction. The types of carbon sink were focused on Normalized Difference Vegetation Index (NDVI), Leaf Area Index (LAI) and Net Primary Productivity (NPP).
