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. Men and women have different perceptions about flash flooding, its causal attributions, and support from public entities regarding planning policies. Prior experience mainly influences the perception of the personal consequences of flash flood events. The results show the relevance of introducing risk education into schools to raise awareness about the causes and consequences of flash floods and improve readiness and responses to this risk manifestation.

使用PCA分析探索山洪风险的感知:以Mindelo,S. Vicente为例(佛得角)

圣维森特岛位于佛得角共和国。它位于萨赫勒地区内,面临多种自然风险,其中之一是山洪。根据一项针对203位受试者的名为“佛得角山洪暴发风险感知”的调查问卷,当人们面对这种自然灾害时,会影响人们的行为决策。在主要维度(分类主成分分析,CATPAA)上进行了多元分析,以确定与山洪风险相关的主要因素。分析结果表明,受教育程度和性别可以解释观察到的差异的50%以上。受教育程度较高的受访者对这种自然风险的了解更多,尽管他们将这种自然风险归因于神圣的惩罚。男性和女性对山洪,其因果归因以及公共实体对规划政策的支持有不同的看法。先前的经验主要影响对洪水泛滥事件的个人后果的认识。结果表明,在学校中引入风险教育以提高人们对山洪的成因和后果的认识,并提高对这种风险表现的准备和响应的意义。
