INVESTIGATION OF RESIDENTS' RECOGNITION ON FLOOD RISK USING LAND PRICE ANALYSIS

Abstract

To evalutate the residents' recognition about the flood risks in the urban area, we analysed the land prices at Tokyo and Osaka with the hedonic approach which relates land price to a variety of environmental factors. Two factors, elevation and inundation depth, that are assumed to reflect the flood risks, were adopted as the explanatory variables of the hedonic price function in Tokyo, while there were no in fluences on land prices due to the flood risks in Osaka. This difference of the residents' recognition between two cities might be caused by the geographical features and the eRectual informations such as hazard maps and news.
