Outline of Final Research Achievements

In this study, we are interested in how people's risk perception of flood damage and their disaster prevention behavior change after being provided with information about flood damage. Therefore, we analyzed changes in people's perception of flood risk due to the provision of information by asking them to respond about their willingness to pay for fire insurance and flood compensation before and after the provision of information about flood damage. If people are sufficiently aware of flood risk, their behavior should not change before and after the provision of information. However, the results of the questionnaire revealed that the provision of flood risk information changed people's insurance purchasing behavior, suggesting the need for further promotion of flood risk information in the future.

Academic Significance and Societal Importance of the Research Achievements

自然災害リスクが身近になってきている状況において、「どのような情報を提供することが事前の防災対策を促すことが出来るのか」といった問いは、生命と財産を守る意味で重要な意味を持つ。また、「現在行われているハザードマップの公表という政策が、どの程度人々の行動に影響しているのか」という問いは、政策の評価につながり、より効率的な政策の提言につながると考えられる。本研究課題は、これらの問いに対して一つの解を出すことであり、重要な学術的意義および実務的意義を持つ。
