Two key concepts, incomplete geographical division of labour and yurui migrations, can address environmental, economic and social problems through interactions of people between urban and rural areas.

The purpose of this research is to develop interactive urban-rural systems that can address global environmental problems and enhance human well-being within global environmental limits. The project investigates our hypotheses that the incomplete geographical division of labour between urban and rural areas and flexible and adaptable (yurui) migrations between urban and rural areas can provide strategies to abate problems related to urban overcrowding. The project will conduct social practical experiments.
