Outline of Final Research Achievements

Recently, the concept of biocultural diversity, which includes both biodiversity and cultural diversity, has been gaining popularity. In this study, we conducted a questionnaire survey of rural communities throughout Japan to determine the impact of paddy field agriculture on biocultural diversity in Japan. Based on the survey results, an analysis of dialectal names of freshwater fish, one aspect of cultural diversity, was conducted. The analysis was conducted separately for Tochigi Prefecture, which had the largest number of data. The results of the nationwide survey were also analyzed separately.

Academic Significance and Societal Importance of the Research Achievements

近年，生物多様性と文化多様性が相互に関連する「生物文化多様性」という概念が提起され，その保全が世界的な課題となっている。本研究の対象となる水田水域では，水田農業が魚類多様性に寄与するとの知見はあるが，魚類多様性が文化多様性に寄与するという知見はない。これを明らかにできれば，水田農業が生物文化多様性の保全機能を有する根拠となる。本研究により明らかにした，水田農業が生物文化多様性の保全機能は，水田農業がもつ多面的機能の一つとして国内外に示せ，日本の水田農業への理解促進につながると期待される。
