Description

<p>In this paper, we estimate changes in disaster risk perception before and after natural disasters in Hiroshima metropolitan area. Specifically, we conducted a Hedonic analysis with Difference-in-Differences approach. We use the hazard map data announced by the government and official land price data announced by the Ministry of Land, Infrastructure, Transport, and Tourism for three years of 2012, 2016, and 2020. In Hiroshima metropolitan area, two large-scale debris flow disasters occurred during this period, in 2014 and 2018. Therefore, we were able to estimate the change in the disaster risk perceptions due to the occurrence of the debris flow disasters.</p><p>We find that, in Hiroshima metropolitan area, residents were aware of the risks of landslides and tsunami in 2012, while they are not aware of the risks of debris flows and floods. We also find that land prices in Hiroshima metropolitan area decreased significantly by 22％ in debris flow risk areas and increased significantly by 12％ in tsunami risk areas in 2020 compared to 2012. From the results, we find that residents in Hiroshima metropolitan area recognized the risk of debris flow and forgot the risk of tsunami after the two heavy sediment disasters.</p>
