Understanding household flood resilience in Tangerang, Indonesia, using a composite indicator method

Flood resilience has emerged as an essential element in flood risk management, emphasizing the need to enhance urban stakeholders' perceptual and mitigative capabilities to minimize vulnerability and mitigate the impacts of floods. Given the significance of reducing vulnerability, it becomes imperative to understand the full scope of resilience in flood risk management strategies. Therefore, the study proposed a framework for understanding flood resilience in an urban flood-prone area using a subjective approach in a study area in three flood-affected Subdistricts in Periuk District, Tangerang City, Indonesia. A mixed-method strategy was employed, combining quantitative data from 354 affected households with qualitative insights from in-depth interviews with ten neighborhood leaders. The quantitative approach utilized composite indicators, criteria weighting, and indices to evaluate flood resilience. The household questionnaire covered various factors influencing flood resilience, including social, economic, home environment, communication and information, social capital, institutional, and risk perception. The main finding of this study is that employing a subjective mixed method, incorporating quantitative and qualitative methodologies, enables a thorough assessment of household flood resilience. The results reveal that communication and information, social capital, institutional factors, and community perception exhibit notably very high indices, while criteria related to social, economic, and home environment factors attain relatively high scores. This study enhances the understanding of household flood resilience by employing a subjective approach, combining quantitative data from flood-affected households and qualitative data from neighborhood leaders. This framework expedites comprehension and yields reliable results.
