Abstract: | Wetlands are important ecosystems on earth due to their capability of preserving water sources, mediating flooding, providing habitats for wildlife, and stabilizing coastlines. Wetlands play a critical role in regional sustainable development because of their ability to enhance resilience against extreme weather events. Maintaining coastal sustainability requires consideration of both the health of coastal wetlands and the resilience of urban systems while mitigating the conflict among social, economic, and environmental goals in land usages around coastal wetland environment. This study investigates a sensitive coastal wetland system located at central Taiwan for demonstration of a sustainable planning practice with an integrated model based on network topology in a socio-ecological context. There are two parts of the integrated model. Whereas a Driving force–Pressure–State–Impact–Response (DPSIR) model helps delineate the complex behaviors among different stakeholders by identifying various indicators, the analytic network process (ANP) quantifies the network topology of DPSIR. According to the survey via questionnaires answered by a group of experts, the DPSIR model is composed of 32 major indicators that can be networked by ANP. The results reveal that an effective ecological conservation depends on a series of mitigation actions, including river and habitat restorations, pollution control, green tourism, and integrated community development via better zoning policies. |
