Analysis of spatio-temporal carbon fixation change in Incheon, Korea, as a result of free trade Agreement

Expansion of a development area can have a negative impact on ecosystems by decreasing or fragmenting habitats. As awareness of the importance of biodiversity and ecosystem services grows, ecosystem service evaluations are receiving increased attention. The geography surrounding the city of Incheon is ecologically valuable because its mudflats and coastal terrain make it ecologically diverse. It is a wildlife habitat and breeding site for endangered species as designated by the Ramsar Convention on Wetlands in 2014, and the subject of disputes between advocates of ecological protection and those favoring human development. This study used the InVEST model to analyze the changes in the ecosystem services in accordance with the agreement on the IFEZ. An analysis showed that the carbon fixation was reduced by 40% due to the development led by the agreement, leading to a decrease in carbon storage of 793,586.25 Mg of C. This study suggests that the value of ecosystem services and expansion of conservation areas should be considered as part of ecological research under economic free trade agreements. Lastly ecological changes associated with IFEZ designation should be examined, and maintenance and management of carbon storage to restore climate controls and the valu-ation of biodiversity should be considered by developers and government officials.  In the natural environment ecology the EIA for development, biodiversity, dominance, natural environment, cultural assets, and protected species are investigated. It is judged that it will be a meaningful study by applying the quantitative evaluation methodology of ecosystem services for the planned development area. Afterwards, it is judged that it can be used as basic data in making development pol-icy decisions through qualitative and quantitative evaluation along with other environ-mental fields by utilizing ICT and AI methods, which are related methodologies according to the 4th industrial revolution.
