    In recent years, wild boars (Sus scrofa) have caused growing damage to farm crops in a hilly and mountainous area of the Tohoku region. In particular, in designated evacuation zones following the accident at the Fukushima Dai-ichi nuclear power plant, there are growing concerns about the expanding range of wild boars and the resulting degradation of farmland.

    After reviewing the main causes and effects of land degradation and erosion in the uplands of mainland Southeast Asia, this chapter presents several case studies of recent land-use changes governed by economic, political and institutional transitions, the expansion of teak and rubber tree plantations in northern Laos and southwest China, respectively, and of monocropping coffee in the Central Highlands of Viet Nam. We explain how these environmental disturbances are altering water and soil resources across different geographic scales, from the agricultural plot to the headwater catchment.

    The purpose of this study is to clarify land improvement method of early collective housing sites developed by Japan housing corporation during 1960's-70's constructed on marshland on Nakagawa lowland in Saitama prefecture - Misato, Yoshikawa, Takesato, and Soka-Matsubara. Those housings are mainly larger scale mid-rise buildings located on Tokyo suburbs and former land-use is paddy field where collective housings had been never built before 1950's since those areas have deep alluvial layer.

    A new method to derive precise land-use and land-cover maps using multi-temporal optical data

    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 discover the changes of household employment structure and of business range for those graziers who have to turn to rear sheep in pens as the background of the policy of returning farmland into forest and grassland. The results of this study are as follows: First, after turning to rear sheep in pens, though the graziers have saved time for other work, the time for feeding has increased to the whole year. In addition, the policy that encourages the rearing of sheep in pens has brought about a growing number of sheep graziers.
