Abstract

PurposeUnderstanding the technical and socioeconomic dimensions to resilience is core to making a business case for property-level flood risk adaptation. The study investigates the socioeconomic factors that impact the technical dimensions to property-level flood risk adaptation, and whether there is a typology of households adopting similar adaptation measures in Port Harcourt.Design/methodology/approachExploratory and inferential statistical analysis of data collated from 407 questionnaires was carried out. Using chi-square analysis, significant bivariate associations were sought between the level of uptake of different categories of property level adaptation and the socioeconomic characteristics of households. A two-step cluster analysis was used to explore discernible patterns of households implementing similar adaptation measures. Logistic regression analysis was further used to evaluate the extent to which socioeconomic parameters impact residents' willingness to undertake adaptation measures given the option of relocation.FindingsThe chi-square analysis highlighted a lack of significant association between some socioeconomic parameters and the uptake of individual adaptation measures. The regression analysis however showed that the socioeconomic parameters exert varying degrees of influence on the residents' willingness to undertake adaptation measures. Two homogeneous groups of residents with similar socioeconomic characteristics were identified via the cluster analysis but did not translate into strongly discernible adaptation differences/patterns.Practical implicationsThe study shows that although socioeconomic parameters to some extent underlie the technical dimensions to flood resilience, there is no distinctive typology of households in Port Harcourt adopting a similar combination of measures.Originality/valueThe study offers insights into understanding property-level flood risk adaptation responses within the context of the developing world.

财产层面的洪水风险适应：复原力的技术和社会经济层面

目的:了解抗灾能力的技术和社会经济维度是制定财产级洪水风险适应商业案例的核心。本研究调查了影响财产级洪水风险适应的技术维度的社会经济因素，以及哈科特港是否存在采取类似适应措施的家庭类型。设计/方法/方法对407份调查问卷整理的数据进行了探索性和推断性统计分析。使用卡方分析，在不同类别财产水平适应的吸收水平与家庭的社会经济特征之间寻求显著的双变量关联。采用两步聚类分析来探索实施类似适应措施的家庭的可识别模式。Logistic回归分析进一步评估了社会经济参数对居民在搬迁选择下采取适应措施意愿的影响程度。卡方分析强调了一些社会经济参数与个体适应措施之间缺乏显著关联。回归分析表明，社会经济参数对居民采取适应措施的意愿有不同程度的影响。通过聚类分析确定了两个具有相似社会经济特征的同质居民群体，但没有转化为明显的适应差异/模式。实践意义研究表明，虽然社会经济参数在一定程度上是洪水恢复能力的技术维度的基础，但哈科特港的家庭没有采取类似措施组合的独特类型。独创性/价值该研究为理解发展中国家背景下的财产级洪水风险适应反应提供了见解。

期刊介绍： The International Journal of Building Pathology and Adaptation publishes findings on contemporary and original research towards sustaining, maintaining and managing existing buildings. The journal provides an interdisciplinary approach to the study of buildings, their performance and adaptation in order to develop appropriate technical and management solutions. This requires an holistic understanding of the complex interactions between the materials, components, occupants, design and environment, demanding the application and development of methodologies for diagnosis, prognosis and treatment in this multidisciplinary area. With rapid technological developments, a changing climate and more extreme weather, coupled with developing societal demands, the challenges to the professions responsible are complex and varied; solutions need to be rigorously researched and tested to navigate the dynamic context in which today''s buildings are to be sustained. Within this context, the scope and coverage of the journal incorporates the following indicative topics: • Behavioural and human responses • Building defects and prognosis • Building adaptation and retrofit • Building conservation and restoration • Building Information Modelling (BIM) • Building and planning regulations and legislation • Building technology • Conflict avoidance, management and disputes resolution • Digital information and communication technologies • Education and training • Environmental performance • Energy management • Health, safety and welfare issues • Healthy enclosures • Innovations and innovative technologies • Law and practice of dilapidation • Maintenance and refurbishment • Materials testing • Policy formulation and development • Project management • Resilience • Structural considerations • Surveying methodologies and techniques • Sustainability and climate change • Valuation and financial investment
