6 J. JUPESTA ET AL.
Chapter 6 includes a policy analysis for Yokohama and the possible
application of this analysis to developing countries. The chapter also exam-
ines policies in related sectors in terms of regulations, standards, planning
and administrative approaches, economic measures, voluntary actions, and
environmental ethics. The analysis on SCs in Japan reveals that such cities
evolve over decades through steady urban development. The study fi nds
that SC concepts may be applied to cities in developing countries, including
informal settlements. Emphasizing informal settlements can be a key for
leapfrogging directly to SC development.
