LEE.J.Y, PARK.M.Y, KANG.J.E. (2023). Heat wave effects on urban residents’ activities based on big data in seoul: focusing on the elderly. ACSP 2023 Annual Conference. (2023. 10. 18. - 2023. 10. 21.) 

 This study examined heat wave effects on urban residents’ activities with a particular focus on the elderly. High temperature events are considered among the most catastrophic weather-related disasters. Heat waves directly affect the health and activities of individuals, increase the incidence of heat-related and chronic diseases, deteriorate health conditions and cause mortality due to related diseases, and directly impact outdoor activities such as leisure, labor, production, and movement. This study targeted Seoul in summer, 2018, and utilized population and meteorological big data to conduct a spatial panel analysis in consideration of spatiotemporal dependencies. 

 Comparing the average sensible temperature distribution with the active population distribution indicated that citizens’ activities were concentrated in areas with relatively low sensible temperatures. To specifically demonstrate this, a spatial panel analysis was conducted on the effect of heat waves on activities of all age groups, the elderly group, and the non-aged group on weekdays and weekends during the entire study period. Sensible temperature-based analysis showed that heat waves resulted in urban residents participating in significantly fewer activities. In particular, this study proves that there was a greater decrease in residents’ weekend activities, when they had more selective activities, compared to weekday activities. Especially, a comparison per age group indicated that activities of the elderly were more vulnerable to heat wave effects than those of other age groups.

 Based on this empirical study, it is necessary to recognize that fewer activities of urban residents should be regarded as a type of heat wave damage. The study also found that policies regarding summer heat waves for the elderly, i.e., a group that is vulnerable to heat waves, should consider the damage to activities and health conditions around residential or neighborhood living areas, in which the elderly are mainly active. This study examined the relationship between urban residents’ activities and heat wave effects at a spatiotemporal level, and the results implied the necessity for directly linking existing heat wave mitigation measures to the activities of urban residents in summer.
