City Resilience towards Coastal Hazards: An Integrated Bottom-Up and Top-Down Assessment

Community resilience is increasingly required to adapt to the effects of the frequency and severity of the ever-increasing number of coastal hazards. This paper uses the case study of the city of Banda Aceh, Indonesia, which was devastated by the 2004 Indian Ocean Tsunami, with the aim of investigating the city’s level of resilience towards coastal hazards. This paper aims to: (i) assess the preparedness of coastal communities; (ii) evaluate the level of resilience of the city to coastal hazards; and (iii) formulate strategic steps in an effort to mitigate coastal hazards in Banda Aceh. The evaluation was conducted using mixed methods (both quantitative and qualitative) through data triangulation. Data collection involved 311 household surveys, two focus group discussions with 30 participants, and interviews with seven representatives from government and non-government organisations. Regarding the survey, the preparedness level of Banda Aceh’s residents is categorised as “low“. The results of overall city resilience assessments are also classified as “low”. This finding indicates that more planned, systematic, and sustainable efforts are needed. Hence, this study also recommends strategies to enhance resilience in dealing with coastal hazards.
