ABSTRACT

Agricultural land has been vastly converted to urban land in metropolitan areas in Korea even though it provides diverse positive functions such as food production, scenic beauty, and temperature control. Without exactly quantifying the positive functions, we may lose this valuable resource too much beyond socially optimum level. As an effort to more accurately measure the positive functions, in this study, we analyzed the effects that converting paddy fields into urban areas had on weather conditions in the southern Gyeonggi Province area using numerical weather simulation based on Weather Research and Forecasting(WRF). In this simulation, we considered two land use scenarios. The first land use scenario represents a situation in which paddy fields sustain as it is. The second land use scenario represents a situation when paddy fields are all urbanized. Through the simulation, the effects of the urbanization of paddy field area on air temperature and relative humidity during hot summer periods were measured. The results from our simulation showed that the urbanization is closely related to the worsening thermal discomfort during sunset to sunrise period especially in the areas where urbanization occurred. This result suggests that paddy fields in metropolitan areas are valuable resource in the aspect of thermal comfort control and when paddy fields in the metropolitan areas are considered to be changed to urban use, there must be sufficient considerations on adverse weather effects.
