Disaster Resilience of Low-cost Houses: Case Study of Thua Thien Hue Province, Vietnam

Abstract

This research documents the post-flood and typhoon conditions of low income housing in the Thua Thien Hue Province, Vietnam, an area prone to extreme flooding in Central Vietnam. The cost of rebuilding houses after a natural hazard has been always a burden for low income households and it often led to the elimination of essential construction practices for disaster resistance. While there has been remarkable improvement in relief and rehabilitation, poor people have been disproportionately vulnerable to extreme events due to their low adaptive capacity and suffered the same damages every year. The research documents existing conditions of low income houses in the Thua Thien Hue province and identifies leading causes of the building failure from the natural disasters. The quality of construction and repairs are assessed based on Coastal Construction Manual and by Federal Emergency Management Agency. In order to examine people's perception toward housing reinforcement as a coping strategy as well as to identify problems and issues associated with achieving stronger and safer housing, focus group and individual interviews were conducted with local residents from four different flood and typhoon-prone communities. The research found that many households in the affected areas now realize the importance of improving housing structures as a coping strategy to resist the impacts of floods and typhoons, however due to low income and a lack of professional instruction and technical guidance in the area, many households still reside in weak and fragile housing conditions that cannot withstand climate related risks. In particular, low-income households spend a considerable amount of their income on housing repair every year. Consultation and communication with professionals about building a resilient housing is lacking. Given that the major immediate recovery action taken by the local people tends to focus on repairing damaged houses, providing proper and applicable construction practices is crucial to improve the housing condition, but also to contribute to reduce poverty in Vietnam.
