摘要Local actors appear as inseparable components of the integrated flood risk mitigation strategy in Vietnam. Recognizing this fact, this study examined the long-term improvement in precautions taken by commune authorities and households between two major floods in 1999 and 2017 by applying both quantitative and qualitative meth-ods. Two flood-prone villages were selected for a survey;one in a rural area and the other in a suburban area of Thua Thien Hue Province, central Vietnam. The findings indi-cate that most villagers doubted the structural works' efficacy and were dissatisfied with the current efforts of local authorities. Households' self-preparation thus became the decisive factor in mitigating risk. While most house-holds have paid greater attention to flood precautions in 2017, others seem to be lagging. Poverty-related barriers were the root causes restraining households in both rural and suburban villages. The suburban riverine residents were further identified as vulnerable by their limitations in upgrading structural measures, which was ascribed to the inconsistency in the ancient town's preservation policy. This multidimensional comparison, in terms of vulnera-bility, emphasized the importance of space-function links in the suburb and the contradictions of different policy initiatives, such as landscape rehabilitation, disaster pre-vention, and livelihood maintenance.
