Evaluating the Effectiveness of Local Adaptation Strategies for Housing Resilience in Ayetoro Coastal Community, Nigeria

Résumé

Background: Coastal communities across Nigeria, including Ayetoro in Ondo State, are increasingly confronted with climate-induced hazards such as flooding, sea incursion, and erosion that threaten housing security. Residents have developed local strategies to protect their homes, yet the effectiveness of these measures remains inadequately evaluated. Without empirical assessment, vulnerable households risk investing in ineffective solutions, worsening long-term vulnerability in communities like Ayetoro, where recurrent housing damage occurred between 2012 and 2022. Study Purpose: This research evaluates the empirical effectiveness of Ayetoro's housing adaptation strategies through three objectives: quantifying performance consistency using descriptive statistics (mean ± standard deviation) with median-based cut-off criteria, identifying socioeconomic and institutional barriers limiting success, and providing evidence-based recommendations to enhance climate resilience through contextually appropriate interventions. Methodology: This research employed a mixed-methods approach, integrating both quantitative and qualitative analyses. Data were collected from 379 residents, yielding 352 valid responses and a high response rate of 92.9%. The quantitative data were analysed using SPSS and Excel, focusing on descriptive statistics such as counts, means, and visual aids like bar, pie, and funnel charts. The effectiveness of housing adaptation strategies was assessed by comparing mean scores to a median cut-off. For inferential analysis, Haldane-Anscombe-adjusted Chi-square tests examined the relationships between building characteristics and climate impacts, while independent t-tests and ANOVA assessed variations in hazard effects across housing types. The Product-Moment Correlation was used to explore the relationship between material choices and building conditions, and Relative Risk (RR) was calculated with Haldane-Anscombe correction to quantify damage reduction probabilities. Qualitative data from Focus Group Discussions were thematically and visually analysed to contextualise the statistical findings. This comprehensive approach provided a deeper understanding of the issues, blending numerical data with the community's lived experiences. Results: The analysis found that placing valuables higher (2.20 ± 0.55) and raised floors (2.14 ± 0.50) as the most effective strategies, demonstrating high consistency (SD≤0.55). Temporary relocation (2.07 ± 0.58) and house fortification (2.07 ± 0.45) demonstrated moderate effectiveness. Permanent relocation (1.77±0.52), drain clearance (1.77±0.42), and drain construction (1.84±0.36) were performed below the median cut-off. Financial constraints, technical gaps, and institutional failures (e.g., derelict Owena Dam) were critical barriers.
