Abstract
Since the 921 earthquake in Taiwan, there has been debris flow whenever it rains heavily. In order to intensify the self-defense ability of disasters, the Soil and Water Conservation Bureau, Council of Agriculture, Executive Yuan starts to promote the debris flow evacuation program and self-defense communities of disasters; meanwhile, making hazard map for the community. Ideally, hazard map is a tool of risk communication, not only just transmitting to residents by the government and experts, but emphasizing the interaction and communication between each other, so as to increase the communities’ self-defense ability of disasters. From the views of the users of hazard map: residents, this study is predominantly based on interviews and is supplemented with questionnaire survey. Aiming at three communities in vulnerable debris flow areas: Shang-an, Hua-yuan, and Tao-shan, this study researches how residents response to hazard map and what the factors influencing residents’ response.
In this study, we find that although three communities have their own characteristics and respond differently to hazard map, factors that influence the responses are the same. Whether the residents read, understand, and believe the hazard map or not, affected by disaster management, educational training, disaster knowledge, and disaster information. The need of the residents toward hazard map is affect by disaster experience, familiarity with the environment, disaster management, information content, and information channel. The opinions and suggestions of residents on making and introducing the hazard map are affected by educational training, information channel, and information credibility.
Finally, rethinking hazard maps from the view of risk communication, hazard maps often become verbal policy advocacy, because the sender give information to the receiver directly; not to conduct the hazard map step by step. According to the residents’ responses to hazard map, participating the process of making the hazard map is important. Furthermore, ignoring the risk communication before and after making the hazard map, some residents don’t know how to use hazard map. Residents’ opinions and suggestions to make and advocacy hazard map should be the content for discussion.
