Outline of Final Research Achievements

This research project aimed to clarify the factors affecting the environmental evaluation of the Lake basin. I conducted a questionnaire survey for residents and analyzed responses by the covariance structure model. As a result, in a case study of Lake Biwa, the study revealed the following: (i) residents who have a strong attachment to Lake Biwa or who have a lot of information sources about the lake are more interested in the lake, and those residents tend to have a higher evaluation of water quality and ecosystem, (ii) other residents with a lots information sources about lake have a high level of knowledge, and those residents evaluated the water quality as good.

Academic Significance and Societal Importance of the Research Achievements

湖沼の環境は流域内の様々な活動の影響を受けるため,住民,事業者,NPO,行政など多様な主体が湖沼の環境保全に参加する必要がある。しかし,多くの政策は専門家委員会での議論や科学的データに基づいた評価によって決定され,市民活動や政策による環境保全の成果のとりまとめや課題の抽出など,評価における市民参加は限定的である。あわせて,国内湖沼におけるCODの環境基準達成率は顕著に低く,今後,環境基準値の達成のみを目指すのではなく,住民の価値観や湖沼との関わりを踏まえて湖沼ごとの目標像や事業内容を検討する必要があると考える。
本研究の成果はそれら検証のための基礎的な資料となることが期待できる。
