Evaluating Flood Economic Damages and Resilience: Focusing on Yabe and Chikugo Rivers

Abstract

Water is an indispensable resource for all socioeconomic activities. Safe and secure water resources and infrastructure development in social capital are important policy issues. However, frequent flood damage caused by typhoons and torrential rains owing to climate change is a concern. The resulting long-lasting economic damage spreads throughout the supply chain. Direct and indirect damages from flood risk should be evaluated. This study proposes a method for estimating the spatiotemporal economic damage by floods. For the Yabe River and the Chikugo River basins in Kyushu, this study evaluates the effect of the economic damage arising from a probable flood risk on the production activities in the basin and surrounding areas.
