About Us

In our e-rec project, we investigate the flow of nutrients in nature and investigate the relation between people's lives in the area and the richness of nature. We are also studying ways to keep rich ecosystems with people in the community and how one's happiness is compatible.


How can we solve both the environmental problem of the basin caused by the imbalance of nutritional balance and the problems unique to the region? We will start reviewing the value of nature in the area and working with the residents to work together to preserve it.
