Almost all people in the world are urbanizing to cities and most of them are moving to coastal cities. The tendency of urban sprawl as urban pressures is caused by urbanization, economic growth, industries, transportation, tourism, and other magnetic factors. Because of the fast growing coastal cities, the environment of the coastal zone is endangered. Many environmental issues and problems affect the coastal cities, such as anthropogenic effects, natural disasters, climate change, and other socio-economic issues which also have severe impacts on the environmental quality. Policy, environment, and management are not well prepared. Nowadays, Integrated Coastal Zone Management (ICZM) is expanding all over the world, also in Indonesia, which is rather a new concept that cannot yet be implemented widely. Based on the fact that the coastal cities should be managed in a sustainable way, the paradigm of ICZM can be introduced as an iterative process in managing the coast. This article explains the need of ICZM for sustainable coastal cities and mostly for Megapoles, as a lesson learned and a paradigm combining new ecological models such as metrofitting, green infrastructure, ecological footprint, and green financial. The public policy should lead to a better life for the people living in the coastal cities based on the local knowledge and public participation of the communities. The discussion will be to define healthy cities in the future, the stressors and the considerations for sustainable coastal cities. This paradigm could be a model as lesson learned and could be implemented for other countries which have similar problems.
