Abstract

To cope with climate change, studies are being conducted on natural-based solutions (NBS) that reduce carbon by utilizing ecosystems and ecological resources ultimately to achieve carbon neutrality. In this study, carbon storage and economic value evaluations were conducted of the coastal land and sea of Busan using InVEST's Carbon and Coastal Blue Carbon models, which are ecosystem service-based evaluation models. As a result, it is estimated that the amount of carbon storage per unit area is lower than that of the entire Busan land area and that if the currently underway or planned development works are completed, the carbon storage of the coastal land areas would be decreased more. Coastal sea areas have less carbon storage than coastal land, but there is great potential for NBS that utilize ecological resources in the future. If the reclamation of public water affects important habitats with high carbon storage levels, it will reduce these levels, and such negative effects could last for a long time. For the sustainable management of Busan coastal areas, ecosystem service-based management strategies are needed considering carbon storage.

전 세계적으로 기후변화에 대응하기 위해 탄소중립 달성을 위한 전략 중 하나인 생태계와 생태자원을 활용하여 탄소를 저감하는 자연기반해법 방안에 관한 연구들이 진행되고 있다. 본 연구에서는 생태계서비스 기반의 평가 모델인 InVEST Carbon, Coastal Blue Carbon 모델을 이용하여 부산 연안 육역과 연안 해역을 대상으로 탄소저장량 추정 및 경제적 가치 평가를 진행하였다. 연구 결과 부산 연안 육역은 부산 전체 육역과 비교하여 단위면적당 탄소저장량이 적으며, 현재 추진 중이거나 계획된 개발이 완료되면 탄소저장량은 더 감소할 것으로 나타났다. 연안 해역은 육역과 비교해 탄소저장량이 적은 것으로 나타났지만, 향후 생태자원을 활용하는 자연기반해법의 잠재성은 크다. 하지만 공유수면 매립과 같은 개발 행위로 탄소저장량이 많은 중요 서식지에 영향을 줄 경우, 탄소저장량의 감소를 초래하며 이러한 부정적인 영향이 장기적으로 지속될 수 있는 것으로 나타났다. 따라서 부산 연안역의 지속가능한 관리를 위하여 탄소저장량을 고려한 생태계서비스 기반의 관리 전략이 필요하다.
