The Haechang tidal flat in Saemangeum provides diverse ecosystem services, including wildlife habitats and blue carbon storage. However, persistent development pressures have created a complex conflict structure involving intertwined social and ecological factors. This study applies systems thinking to analyze the structure of the tidal flat's social-ecological system (SES) and, based on this analysis, proposes resilient blue carbon management strategies. Through causal loop diagram analysis, the study identified several reinforcing and balancing feedback structures that characterize the systemic behavior of the SES. The analysis revealed a “Limits to Growth”-type archetype, in which continuous reclamation and habitat loss lead to biodiversity decline, weakened community livelihoods, and reduced policy trust-creating a self-reinforcing cycle of ecological degradation. In contrast, balancing feedbacks associated with governance participation and ecological restoration were recognized as strategic intervention points for transforming this unsustainable trajectory. Based on these structural insights, this study proposes governance-based social transfor- mation and ecological restoration through Blue-Green Networks as core strategies for developing a resilient coastal management framework.
