In modern Japanese society, because volunteer activities are being conducted in a variety of forms, those who wish to volunteer can participate in volunteer activities that suit their own situation. Further, in a highly information-oriented society such as modern Japan, many kinds of information systems can be used to conduct a variety of volunteer activities. Also, know-how concerning the introduction and methods of volunteer activity and recruitment for participants in volunteer activities are introduced using various information media, and there are many volunteer activities to choose from. Therefore, it is possible that through the diversification of volunteer activities, many people become involved in volunteer activities on a long-term basis, using ways of doing so that are possible for themselves.展开更多

Therefore, the research on flood mitigation service(FMS) of ecosystem should be paid more attention to mitigate the risk. In this paper, we assessed FMS in the Upper Reaches of Hanjiang River(URHR), China from 2000 to 2014 using the Soil Conservation Service Curve Number(SCS-CN) model, and further simulated the future FMS under two climate scenarios(in 2020 and 2030). The results reveal that the FMS presented a fluctuating rising trend in the URHR from 2000 to 2014. The FMS in southern URHR was higher than that of northern URHR, and the change rate of FMS in the upstream of URHR(western URHR) was higher than the downstream of URHR(eastern URHR). The future FMS under scenarios of Medium-High Emissions(A2) and Medium-Low Emissions(B2) will decrease consistently. As land use/land cover changes in the URHR are negligible, we concluded that the change in FMS was mainly driven by climate change, such as storm and runoff. Our study highlights that climate scenarios analysis should be incorporated into the assessment of hydrologic-related services to facilitate regional water resources management.展开更多
