Constant technological development enables collection of large quantities of environmental data, but at the same time, it reveals the insufficiency of such data sets to diagnose ecosystem health completely. New technology always shows us new scientific aspects and findings. It is of great concern to scientists to understand what type and/or how many scientific evidences can be enough for a person to proof ecosystem healthy and to transform their activity to ecosystem friendly, from transdisciplinary viewpoints.

We have been focusing on a linkage between community-based ecosystem services utilization and recognition of fundamental scientific evidence to judge ecosystem health for the community. Based on several case studies in Japan and Southeast Asian countries, we are proposing a hypothesis about the transformation process named “Area-Capability (AC) cycle.” In the AC cycle, appropriate ecosystem utilization enhances quality of life and facilitates conservation minds and actions of a community. It was suggested that improvement of appropriate technology, strengthen of community, collaboration among community, scientist and governments, and cultivation of hope for local life seem to be keys for the cycle.
