Environmental constraints are becoming increasingly severe, and now more than ever it is time that we confront head-on the change from an "underground resources" type of civilization to one with a new way of life and technology that embraces a sense of nature. To do so, we need to understand the process of the civilization change. We must change our way of thinking to backcasting in order to design future lifestyles and learn from the elderly who lived with nature under severe environmental constraints more than 70 years ago. We must also learn from nature directly, the only sustainable society on earth.

This book introduces Bio-TRIZ and ontology engineering to match and find technologies needed for spiritually affluent lifestyles. It provides many examples of Japanese cities that conducted lifestyle design projects based on nature technology. The book is a great reference for graduate-level students of environmental studies and engineering and for researchers in innovation, social science, engineering, and public policy, especially those with an interest in lifestyle change for a sustainable society.
