Abstract

Empirical studies of residential flood vulnerability have generally concentrated on either the geophysical characteristics or the socio-economic characteristics of a given region, rather than a combination of the two. In addition, studies using subjective assessments of flood vulnerability are not very common. However, due to the fact that people’s perceptions influence their risk behaviour, and therefore their vulnerability, understanding perceptions about a phenomenon is very significant for the design of effective communication as well as mitigation, coping, and adaptation strategies. This study uses a digital map (to calculate mean elevation, slope, proximity to lagoon, sea, and drain length by area) and the EDULINK Round II Household Survey (for socio-demographic characteristics of households) for the analysis. Perception of flood vulnerability is derived from responses from heads of households to the question, “Do you perceive your household to be vulnerable to floods?” The responses are either in the affirmative or negative. Results show that even when a subjective assessment of vulnerability is undertaken, it is geophysical characteristics that have significant associations with perceptions of flood vulnerability.
