| Abstrak/Abstract |
Sustainability assessments of marine protected areas (MPAs) are essential for improving the e?ectiveness of management e?orts. Since sustainability is closely related to the concept of intergenerational well-being, measuring and tracking it through time is crucial. Therefore, this study will use the system dynamics approach applied at Pieh marine park as the study site. A system dynamicsmodelwasbuiltcomprisingfoursub-models: ?shpopulationdynamics,coralreefcoverage, tourism, and pollution. The goodness-of-?t test of the model indicated low and unsystematic model error. The sustainability assessment was conducted using the three principles of sustainability proposedbyHermanDaly,whichde?nesustainabilityforresourcemanagementbasedonthechange in the amount of renewable resources, non-renewable resources, and pollution. The sustainability assessment determined that Pieh marine park cannot sustain economic activities in its area, indicated by decreasing renewable resource indicators in the form of ?sh population dynamics, coral reef coverage, and increasing pollution levels. Several management interventions can be applied to improve sustainability, including lowering the total allowable catch, coral transplantation, and improved waste management.
