    This study aims to understand the effective management of abandoned properties such as forest, farmlands, houses in depopulated areas in Japan. Specifically, this study focuses on 'absentee landlords' who own their property away from their current residence. Descriptive analyses of the Internet survey on absentee landlords who own properties in depopulated areas in Japan shows that the absentee landlords who cannot manage their forests properly also cannot manage paddy fields and houses properly.

    In this study, we compared pixel-based image analysis and object-based image analysis (OBIA) as methods of land cover classification of urban areas, using high resolution digital aerial photography. The study area was Setagaya Ward, Tokyo, Japan, and we carried out supervised classification using aerial photographs with 25-cm spatial resolution, and with both visible bands and a near infrared band. The overall accuracy of the object-based classification was approximately 6 to 20 percentage points higher than that of the pixel-based classification.

    Asian dust events are massive meteorological phenomena during which dust particles from Chinese and Mongolian deserts are blown into the atmosphere and carried by westerly winds across Northeast Asia. Recently, there has been steady increase in both the frequency and the severity of Asian atmospheric dust events. Concern has been expressed regarding the potential health hazards in affected areas. The principal nature of the damage associated with Asian dust events differs between the emission (sandstorm) and downwind (air pollution) regions.

    Population and land use outmigrations from urban to peripheral areas can result in nonfunctional unmaintained historic structures which deteriorate to the point where removal is cheaper than removal or demolition by neglect The increasing rate of neglected historic structures is a growing concern There is a need for research investigating connections between urban growth management and its effect on neglect This paper applies Newmans 2013 conceptual model of measuring neglect to Geographic Information Systems comparing rates of neglect in historic Doylestown Quakertown and Bristol boroughs

    This paper presents an evaluation of the multi-source satellite datasets such as Sentinel-2, Landsat-8, and Moderate Resolution Imaging Spectroradiometer (MODIS) with different spatial and temporal resolutions for nationwide vegetation mapping. The random forests based machine learning and cross-validation approach was applied for evaluating the performance of different datasets.

    To understand the rainfall-runoff process and sediment delivery process in headwater catchment, hydrological observation and the monitoring of suspended sediment concentrations (SSC) was conducted at a forested headwater catchment in Japanese Alps region. The study site is Nodagasawa watershed (37 ha) within Terasawayama Station, Research Forest of Shinshu University, Japan. At this catchment, notably quick rainfall-runoff response was observed as with the runoff characteristics reported in other catchment underlain by granite.

    Urban residents’ health depends on green infrastructure to cope with climate change. Shrinking cities could utilize vacant land to provide more green space, but declining tax revenues preclude new park development—a situation pronounced in Japan, where some cities are projected to shrink by over ten percent, but lack green space. Could informal urban green spaces (IGS; vacant lots, street verges, brownfields etc.) supplement parks in shrinking cities?
