Abstract :
[en] ABSTRACT Urban flooding is one of the most frequent and destructive hazards, with disproportionate impacts in vulnerable urban neighborhoods. Although community resilience is critical for reducing flood impacts and supporting recovery, the integrated quantitative assessment of interactions between household, collective, and institutional factors remains limited, particularly in vulnerable urban contexts. This study aims to explore how household preparedness, residential context, collective dynamics, and institutional communication interact to shape community resilience to flooding in vulnerable urban neighborhoods of Antananarivo, Madagascar. It adopts an integrative community resilience framework combining process, collective, and structural dimensions. The analysis is based on a standardized household survey of 400 households across 20 flood‐prone neighborhoods, using household typology and quantitative analyses. Results show that demographic and socio‐economic characteristics play a limited role in shaping collective resilience. In contrast, household preparedness, neighborhood configuration, and the perceived quality of institutional communication emerge as the main determinants of community preparedness and collective response. Although the household typology identifies distinct vulnerability profiles, these profiles do not translate into significantly different collective dynamics, underscoring the central role of organizational and relational mechanisms in shaping community resilience. These findings call for multi‐level flood resilience strategies that prioritize institutional communication, community intermediaries, and participatory governance mechanisms over predominantly infrastructure‐centered approaches in resource‐constrained urban contexts.
