Coastal deltaic cities are facing increasing flood risks due to sea level rise, climate change, and socio-economic development, particularly those in Southeast Asia. In such context, public support for adaptation policies is crucial to ensure timely adaptation and to enhance societal capacity, contributing to climate resilience. However, various adaptation policies being implemented have encountered a lack of public support, leading to inefficient adaptation processes (ex., the Garuda project in Jakarta, a relocation project in the Philippines, the raising of roads in Ho Chi Minh City, or the super levee project in Tokyo). There is a lack of understanding of what leads to public support for adaptation strategies and the relationships between these factors. Cao et al. (2024) set the foundation to examine how to analyze public support for adaptation policies, proposing the Foundation of Adaptation Policy Support (FAPS) model, and using Tokyo as a case study.
The present study applies the FAPS model (Cao et al., 2024) to a number of Southeast Asian cities, including Manila, Ho Chi Minh City and Jakarta, gauging the three categories, including risk perception (perceived severity and vulnerability, climate change belief, knowledge about floods, flood experience, and issue importance), policy perception (policy awareness, perceived effectiveness, additional benefits, policy support, and preparedness and response), and psychological factors (negative feelings, social norms, trust, environmental attitudes, and place attachment). In the presentation, the authors will discuss the preliminary results of the latest fieldwork in the case study cities, discuss regional similarities and differences between countries, and highlight the key factors that determine policy support for flood adaptation strategies in Southeast Asia cities.
