    Here we propose an accurate and robust method for large-area land-use and land-cover (LULC) mapping using multi-temporal optical data. The conventional method for LULC classification usually uses time-series data at regular intervals to consider the seasonality of LULC. However, high-resolution optical data have considerable seasonal biases, making it difficult to use time-series data.

    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.
