[HTT18-01] Environmental traceability methodology by multi-isoscapes
Keywords:Stable isotopes, Milti-isoscapes, Environmental traceability
We are conducting a research for establishing a methodology for how to use the concept of environmental traceability. A combination of quantitative and qualitative tools, including “Multi-Isoscapes” (use of multiple elements and multiple isotope ratios, together with GIS-based mapping technique), social surveys, and workshops, are deployed to investigate the role of environmental traceability in confronting environmental issues. We hypothesize that the role and perception of traceability methods in transdisciplinary processes will differ among stakeholders and that the co-production of “Multi-Isoscapes” can act as an effective “bridging tool” for understanding and explaining variation in local environments. The ultimate objective of this research is to demonstrate the effectiveness of multi-isotopic information in solving global environmental issues. Research is taking place at sites in Ono City, Fukui; Otsuchi Town, Iwate; Saijo City, Ehime; Oshino Village, Yamanashi; the Chikusa river watershed, Hyogo; Lake Biwa and Yasu river watershed in Shiga; and Silang-Santa Rosa sub-watershed in the Philippines.
