Ⅰ. Background and Aims of Research
1. Background
oAs climate change progresses, extreme weather events such as localized heavy rain and typhoon are increasing in frequency as well as intensity.
ㅇNot only has the rainy season become longer compared to the past, but the amount of precipitation during the rainy season has also increased.
ㅇIt is expected that the number of extreme precipitation days will increase in future climate scenarios.
ㅇThe acceleration of sea level rise increases the tsunami height when a typhoon occurs, which leads to coastal flooding.
oExtreme weather events lead to economic loss.
ㅇDamage from typhoons and heavy rain accounts for 87.7% of the total damage, resulting in significant casualties and property damage.
ㅇIt is predicted that significant economic damage costs will increase even more under future climate scenarios.
oThe need to study the damage costs of flooding based on empirical analysis has been raised.
ㅇPrevious domestic studies have been conducted by calculating property damage in the expected flood zones, but it is difficult to estimate the long-term cost at the present time.
ㅇThere is a risk of underestimating damage costs when using land and housing appraised value or damage compensation amount.
ㅇQuantitative damage costs calculated based on past experience are needed to identify and compare regional climate change vulnerability.
2. Research Aim
oWe aim to estimate the cost of damage from past extreme weather events by estimating the impact of flooding on housing prices.
ㅇThe study addresses concerns about overestimation of climate
