São Vicente Island is in the Republic of Cape Verde. It lies within the Sahelian zone and faces several natural risks, one of which is flash flooding. Based on a questionnaire entitled Flash Flood Risk Perception in Cape Verde, applied to 203 subjects, influence the behavioural decision making adopted by people when confronted with this natural hazard. A multivariate technique was conducted on the main dimensions (categorical principal components analysis, CATPCA) to identify the primary factors associated with the perception of flash flood risk. Results of this analysis suggest that education level and gender explain more than 50% of the observed variance. Respondents with higher education show greater knowledge about this type of natural risk, although they ascribe its occurrence to divine punishment.
