NAGOYA — Traditional Japanese land and marine conservation and utilization efforts known as "satoyama" and "satoumi" can serve as examples of how other nations can preserve and protect ecosystems and biodiversity, two symposiums at the COP10 meeting in Nagoya heard Tuesday.

A total of 51 organizations joined hands Tuesday to launch an international platform to pursue sustainable use of traditional landscapes and protect biodiversity in satoyama woods and farmlands.

In the satoyama concept, human help plays a vital role.
