Extreme Weather Event and Health Risk
Due to climate change and anthropogenic activities, extreme weather events such as heat wave, dust storm and haze have been found globally. At the same time, frequency, severity and intensity of these extreme weather events have been increased.
In order to reduce the fatal risks from extreme weather event and develop protocols for future health planning, this project uses multiple cities (e.g. Hong Kong, Vancouver) as study sites and creates high resolution exposure maps (e.g. temperature, air pollution) with geospatial applications. These maps were used to analyze the association between extreme weather events and cause-specific mortality, as well as to identify vulnerable population and deprived building structures/types. The goal of this research is to locate the potential risk spots of each city, and to apply the health risk map for emergency use and community planning.
