The proposal to the 21st century coastal ecocity development

Most cities have been built in the coastal zone which utility value tends to use highly. It is a reason that it has the various environmental characteristics in coastal sea area, and it is easy to carry out movement of people and the load using seaborne traffic. Because of it, all over the world, concentration of the population and industry to the coastal city caused the pollution problems and the coastal environment problems. Particularly overdevelopments of the coastal sea area and coastal line have deteriorated the amenity for human being. Also on the Osaka Bay area, which is enclosed sea area, large population has concentrated on coastal zone, and the precious environment of coastal zone has been consumed. As a result the amenity for human being has also been lost. In recent years, although we came to be conscious of Osaka Bay as a scene, generation of the consciousness of living in symbiosis with nature of Osaka Bay is a future subject. Coastal sea area has played the precious roles. Coastal eco-city is really supported in the characteristic of the coastal sea area overlooked by the time which gave priority to economic development of coastal land area. This study showed the concept of space and the functions of coastal eco-city of Osaka Bay, and the step to realization of coastal ecocity, such as stakeholder´s measure, technical measure, and social system.
