ASSESSMENT OF REGIONAL CHARACTERISTICS FOR COASTAL DISASTER PREVENTION INFRASTRUCTURE CONSIDERING WELL-BEING AND ECOSYSTEMS IN JAPANESE COASTAL AREAS

Abstract

 This study developed a framework for infrastructure assessment, including green infrastructure (GI) and gray infrastructure (GyI), and examined the impact of coastal infrastructure on humans and nature. The results of the survey showed that the well-being was related to the size of the hazard, and the smaller the hazard, the higher the level of satisfaction. The results also indicated that there is a limit to the level of satisfaction that can be obtained through urbanization, and that GI ecosystem services may lead to higher levels of satisfaction. The results of this study suggest the importance of considering the balance between GI and GyI in terms of both well-being and natural demand.
