Abstract

Understanding lay people’s flood risk perceptions has become an essential component of flood risk management especially with respect to ascertaining possible responses both to risk situations and to government actions. However, different contextual factors determine how they respond, and little has been done in the African urban context to study flood risk perception trends. Using data from 612 household questionnaires, this paper documents the hazard-related and cognitive factors of flood risk perception (measured using perceived likelihood of flood-induced property damage, as the dependent variable) in 3 neighbourhoods of Kampala, Uganda. Correlation and ordinal regression analysis established a positive influence of flood experience on flood risk perception in 2 of the neighbourhoods. In contrast, it has a negative influence in the third neighbourhood, which also goes for existing mitigation measures. However, in the latter, flood-induced property damage and existing mitigation measures showed a positive influence. Additionally, flood-induced financial costs positively influence risk perception in two of the three neighborhoods. These differences are associated with case characteristics, including the widening of drainage channels and socio-economic characteristics, and partially confirm the findings from previous studies. The contextual trends provide insights to improve the application of the Protection Motivation Theory.

乌干达坎帕拉家庭洪水风险认知中与灾害相关因素和认知因素的影响
了解普通人对洪水风险的认识已成为洪水风险管理的重要组成部分,特别是在确定对风险情况和政府行动可能采取的应对措施方面。然而,不同的环境因素决定了他们的应对方式,在非洲城市环境中,对洪水风险认知趋势的研究还很少。本文利用 612 份家庭调查问卷的数据,记录了乌干达坎帕拉 3 个社区与灾害相关的洪水风险认知因素(以洪水造成财产损失的可能性为因变量)。相关性和顺序回归分析表明,在其中两个社区,洪水经历对洪水风险认知有积极影响。相比之下,洪水对第三个社区的影响是负面的,这也与现有的减灾措施有关。然而,在后者中,洪水造成的财产损失和现有的减灾措施却产生了积极影响。此外,在三个社区中的两个社区,洪水引发的财务成本对风险认知有积极影响。这些差异与个案特征有关,包括排水渠道的拓宽和社会经济特征,并部分证实了以往研究的结果。背景趋势为改进保护动机理论的应用提供了启示。

期刊介绍: Environmental Science & Policy promotes communication among government, business and industry, academia, and non-governmental organisations who are instrumental in the solution of environmental problems. It also seeks to advance interdisciplinary research of policy relevance on environmental issues such as climate change, biodiversity, environmental pollution and wastes, renewable and non-renewable natural resources, sustainability, and the interactions among these issues. The journal emphasises the linkages between these environmental issues and social and economic issues such as production, transport, consumption, growth, demographic changes, well-being, and health. However, the subject coverage will not be restricted to these issues and the introduction of new dimensions will be encouraged.
