Flood risk is increasing worldwide and there is a growing need to better understand the co-benefits of investments in disaster resilience. Utilizing a multinational community flood resilience dataset, this paper takes a systems approach to understanding community-level flood resilience. Using a cluster analysis and bivariate correlation methods, we develop a typology of community flood resilience capacity based on community characteristics and five capitals (human, financial, natural, physical, and social). Our results reinforce the importance of context-specific policymaking and give recommendations of four distinct clusters to investigate the relationship between flood resilience and prevailing development conditions. We especially find that communities with higher interactions between their capital capacities tend to have higher flood resilience levels. Additionally, there are indications that stronger interactions between community capacities can help to induce multiple co-benefits when investing in disaster resilience. Our results also have important policy implications on the individual community level. For example, based on our results, we suggest that communities with lower flood resilience capacities and interactions can best build resilience on leveraging their relatively higher human capital capacities to strengthen the financial and social capitals. Negative effects might happen for urban communities when co-benefits of natural and physical capital are not fully integrated. The highest flood resilience capacity is found in communities with a well-balanced household income distribution which is likely a contributing factor to the importance of financial capital for this cluster. Our results emphasize the importance of an integrative approach to management when implementing systematic flood disaster resilience metrics and development measures.

社区抗洪能力的类型

全球范围内的洪灾风险正在增加,并且越来越需要更好地了解抗灾能力投资的共同利益。利用跨国社区的抗洪能力数据集,本文采用系统的方法来理解社区级的抗洪能力。使用聚类分析和双变量相关方法,我们根据社区特征和五种资本(人力,财务,自然,物质和社会资本)建立了社区防洪能力的类型学。我们的结果强调了针对具体情况制定政策的重要性,并提出了四个不同类别的建议,以调查防洪能力与当前发展状况之间的关系。我们尤其发现,其资本能力之间相互作用程度较高的社区往往具有较高的抗洪能力。此外,有迹象表明,社区能力之间的更强互动可以帮助在投资于抗灾能力时引发多种共同利益。我们的结果对个人社区也有重要的政策影响。例如,根据我们的结果,我们建议洪水抗灾能力和互动能力较低的社区可以最好地利用相对较高的人力资本能力来增强金融和社会资本,从而建立抗灾能力。当自然资本和物质资本的共同利益没有得到充分整合时,对城市社区可能产生负面影响。在家庭收入分配均衡的社区中发现了最高的抗洪能力,这很可能是导致金融资本对该集群重要性的一个促成因素。我们的结果强调了在实施系统的洪水抗灾能力指标和发展措施时采用综合管理方法的重要性。
