Understanding evolution of urban flood risk management using socio-ecological-technological systems lens
Abstract
Urban flooding is a pressing issue with increases in extreme precipitation and urbanization worldwide. However, few examined changes in flood risk management (FRM) across cities using a mixed-method. We examined changes in urban FRM in six cities in North America and Asia to understand how each city has evolved FRM based on each citys governance document and experts interviews. We first examined city comprehensive and hazard mitigation plans to extract FRM strategies and social learning using the socio, ecological, and technological systems (SETS) framework. Additionally, we seek to understand the role of experts and the construction of experts perception on urban FRM strategies and decision-making processes by interviewing academic researchers, city practitioners, engineers, and infrastructure managers across six cities in the United States, South Korea, and Japan. The Q methodology and Content analysis reveal experts' priorities or values that are constructed according to the socio-cultural, natural, and political contextual characteristics. The study results show how and why different social learning patterns exist across the study cities between governance documents and flood experts perceptions on urban flood risks. With these results, we characterize how SETS factors are associated with FRM individually and collectively.
