Building capacity for disaster risk reduction requires integrating local and scientific knowledge. We focus on local and scientific knowledge of the safety of housing in typhoons' wind, focusing on roof and wall systems. To identify alignments and misalignments between household and engineering understanding of safe housing, we conducted semi-structured interviews with 170 households that received new houses from organizations following Typhoon Yolanda in the Philippines. We qualitatively coded and analyzed these interviews to identify what housing components households expect to fail first, their preferred failure, and how they plan to modify their house to be safer in typhoons. We compared these responses to three results from engineering assessments: the governing failure mode, the failure mode that best meets safety performance objectives, and the quantified impact of design modifications. Household perceptions and engineering assessments were well-aligned when focusing on the damage expected to a single component and how to improve the performance of a single component. However, perceptions and assessments were misaligned at the housing level as households did not consider how housing components worked together as a system to influence performance. Households often did not recognize that modifying one component, such as the roof, would have an adverse impact on the performance of other components, such as the wall. This study is one of the first to systematically compare perceptions and assessments of housing safety and advances understanding of alignment, or misalignment, of local and scientific knowledge of safe building practices. We recommend that future post-disaster training programs incorporate discussions of a house's load path to focus on how components work together, enabling design and modification decisions that support improved housing performance.

How residents perceive housing safety affects how structures are designed, built, and maintained. This study assesses the perceptions of housing safety through a survey of over 450 individuals in communities that received post-disaster housing reconstruction assistance following 2013’s Typhoon Yolanda, and that were potentially vulnerable to earthquakes. We analyzed how housing design factors, post-disaster program elements, personal characteristics, and hazard type and exposure influenced safety perceptions. Overall, individuals were most concerned with the safety of their roofs during hazard events and perceived their houses would be less safe in a future typhoon than a future earthquake. Housing material significantly impacted safety perceptions, with individuals in wood houses perceiving their houses to be the least safe. Individuals living in areas more exposed to hazards also perceived their houses to be less safe. Being relocated after the typhoon, witnessing good or bad practices during reconstruction, and prior disaster experience also significantly influenced perceptions of housing safety. These results are used to make recommendations on how implementing organizations can most beneficially intervene with program factors to improve local understanding of housing safety.

Participation in post-disaster shelter reconstruction is recognized as an important factor for supporting the sustainability and resiliency of the built environment. Engaging communities in the reconstruction process can help build community capacity and lead to sustained success of recovery projects. However, existing practice often assumes that differing forms of participation are independent of one another, neglecting to understand the influence that early participation may have on participation in later stages of the project. Past literature identified how communities participated in the planning, design, and construction phases in 19 different shelter projects following Typhoon Haiyan in the Philippines. For this research, we used fuzzy-set qualitative comparative analysis (fsQCA) to analyze how participation in earlier phases of planning and design affected participation in the construction phase. Results show that early participation, particularly in the decisions of the planning phase, are critical in shaping later participation. Findings also reveal that participation is a process linked across multiple project phases and should not be viewed as a set of independent tasks. These results inform disaster recovery practice by encouraging project strategies that incorporate community participation from the beginning through the end of a project’s lifecycle.
