Community Activities to Conserve Tidal Flat Ecosystems -October 1996, Kaga City, Ishikawa Prefecture-.

In Japan in the 1990s, the loss of tidal flats and wetlands became a serious environmental problem due to the development of coastal areas that accompanied rapid economic growth. In particular, projects such as seawall construction, reclamation, and harbor development were destroying stopover sites for migratory birds, spawning grounds for fish, and habitats for shellfish and benthic organisms, with a major impact on the ecological chain. In addition, interest in the Ramsar Convention was beginning to grow in Japan, and the "value of wetlands" was being reevaluated against this historical background.
In Kaga City, Ishikawa Prefecture, tidal flats that once flourished as lagoons have shrunk due to residential land development and the construction of fishing ports, resulting in a decrease in the population of shellfish and birds. In response, local residents, fishermen, and environmental groups began working together to restore and preserve the mudflats. While lobbying the government, they also conducted their own vegetation surveys and bottom sediment analysis of the tidal flats to re-evaluate them.
These activities were not limited to simply protecting nature, but also provided an opportunity to "reevaluate the relationship between one's own life and the environment. By collaborating with local elementary and junior high schools to hold observation and environmental study sessions, the project also included an educational aspect to convey the importance of tidal flats to the next generation. In addition, residents took the initiative in cleaning up the tidal flats on a regular basis, providing an opportunity to learn about the problem of marine debris and its relationship to domestic wastewater.
This movement spread nationwide in the late 1990s and influenced concepts such as "satoumi" and "eco-coast. The case of Kaga City is now regarded as a pioneering example of community-based ecological recovery, as a model of symbiosis between the natural environment and human life. The tidal flats were not just a natural space, but a "place of learning and collaboration" that restored the relationship between people and nature, and were about to come back to life again.
