Households’ resilience to flood disaster in Lagos State, Nigeria: developing a conceptual framework unifying disaster resilience components and dimensions

Understanding people’s resilience to flood disaster is necessary, considering their different levels of vulnerability in terms of material and human losses. This study therefore assesses households’ resilience to flood disaster in Lagos State in order to determine their ability to absorb, adapt to and transform from flood disaster impact. Theoretically, a conceptual framework to unify the dimensions and components of disaster resilience was developed from the General Systems Theory, Parent-Child Relationship Design Pattern, and Resilience Capacity Theory. A descriptive cross-sectional survey based on quantitative research design was employed for this study. Using a multistage sampling technique, six local government areas in the state were selected based on the different flood types founded on historical evidence and were delineated into pluvial, fluvial and coastal zones. Data were thereafter collected through questionnaire administration on 512 sampled household heads from 4093 population on flood-risk streets. Descriptive statistics comprising frequency distribution, cross-tabulation and arithmetic mean were used in analysing the data. The results showed that within each of the zones, the mean indices for the dimensions range from 2.10 to 3.97, indicating their low, moderate and high levels under the different components. In all the zones, the mean indices for the components are within 2.5 and 3.4, indicating a moderate level. This suggests that households’ resilience to flood disaster differed based on the dimensions within each component for each flood zone but their resilience is similar across the zones based on the different components using the proposed unification framework.
