Pathways of multi-hazard post-disaster housing reconstruction among Ivatan Indigenous households

Most disaster-affected populations face the complex task of reconstructing their dwellings with minimal or no external support. However, not much is known about the self-initiated reconstruction pathways of households, especially among Indigenous groups needing to address the competing impacts of multiple hazards. We conducted a case study analysis based in Itbayat, Batanes in the Philippines to understand the housing reconstruction trajectories of the Ivatan Indigenous households after the 2019 earthquakes that redefined their typhoon-resilient construction practices. Using interviews and focus group discussions, factors affecting the reconstruction process were elicited. Then, using concept maps, we explored the linkages of these factors leading to the adoption of the emergent housing outputs. We found that the emergence of new housing typologies that displaced the vernacular architecture was influenced by the compounded urgency to reconstruct houses, perceptions of housing safety influenced by the seismic events, the nature of aid provided alongside households’ financial capacity, and the regulatory barriers affecting traditional resource extraction. To achieve structural housing safety, this study demonstrates the need for policies that enable and guide reconstruction in emergency contexts, as well as systems to channel aid to provide equitable opportunities to build back safer. Additionally, the role of local governance is shown to leverage the use of existing indigenous construction practices salient for rebuilding. This study builds upon the heightened imperatives in the disaster risk reduction practice and policy environments to focus on the multi-hazard realities affecting communities and the use of local and indigenous knowledge to reduce disaster impacts. •Indigenous households adopt construction trade-offs for multi-hazard reconstruction.•Local ordinances can institutionalise the use of indigenous construction practices.•Regulatory barriers impact the achievement of structural housing safety.
