Abstract
In a basin, the environment along the waterside in upstream and downstream regions is very different. For example, depopulation and conservation of forests are serious problems in upstream regions. In downstream regions, access to water is important. Therefore, it is necessary to consider the differences among regions in environmental management along the waterside. The environmental valuation by local residents is also important in environmental management.
We clarified the environmental valuation along the waterside through the impressions of local residents to consider differences among regions in environmental management. According to Cramer's coefficient of contingency and factor analysis, the environmental valuation along the waterside is composed of ‘the components of impression', ‘impression' and ‘common factors'.
Second, this study clarified characteristics of the regions by conducting a survey of the Kamo River Basin. Regions for implementation of a social survey are chosen based on the characteristics ofregions. A social survey was implemented to clarify problems and characteristics of the regions and impressions of the local resident along the waterside.
In this study, it was shown that this valuation can be applied to the environmental valuation by taking into account the characteristics of up and down stream regions. It was also clear that the impression analysis also contributes to environmental management along the waterside. Finally, environmental management along the waterside should be done with consideration for ‘diversity and integration'.
