Siang-Heng Wang was interested in the field trip when he was studying for Ph.D. research in International Degree Program in Climate Change and Sustainable Development (IPCS) at National Taiwan University. He likes observing any natural responses interfered with by people, primarily focusing on the land surface, like how water vapor responds to agricultural behavior. While studying in IPCS, the teachers encourage students to find interesting issues about the connections between natural science and social science. He follows this expectation and his interest in establishing this research about how people's management strategies affect the microclimate in the tea fields, a kind of short canopy landscape with a vulnerable microenvironment. In this thesis, he clarifies the detailed analysis of observational data, and he will try to model future situations under different climate scenarios in the future.
