A Study of a Residential Environment Risk Assessment Method for Natural Green Areas with Unplanned Factories in Korea using The Climate Change Risk Assessment Model - The Case of Sawol Town, Incheon
The South Korean government eased construction regulations to facilitate the construction and extension of factories even in nonurban green areas as well as industrial areas, and this accelerated the establishment of more factories. As a result, unwanted facilities including factories have continuously increased in nonurban areas such as natural green areas. The residential environment was further deteriorated due to the emissions of chemical substances, dusts, noise, and odor from such facilities. Existing studies of residential environment risks mainly focused on facility expansion and infrastructure improvement projects using residential environment improvement index and residential management index. Therefore, existing assessment frameworks are unable to properly estimate residents’ health and the safety of environmentally unwanted facilities. Considering this, the present study developed a Residential Environment Risk Index based on the Climate Change Risk Assessment Model provided by the UNISDR and IPCC. Sawol Town, which once came to much public attention for the serious damages caused by the environmental impact of various unplanned workplaces such as factories, was selected as study receptor. The Residential Environment Risk Index of the town was calculated using ArcGIS, and the correlation between the index and the prevalence of diseases for the past 12 months was investigated. Residential environment risks were assessed in reference to the start point of thyroid disorders which are mainly caused by stress.
