Abstract Body

The wetlands have suffered continuous damage in recent years. Ninety percent of the wetlands were, in particular, located in the cities and peri-urban areas, which caused a lack of a resilient supply of the desired set of ecosystem functions. To improve the resilience in wetlands, the International Union for Conservation of Nature suggested the new concept, Wetland City. However, the Wetland City is facing challenges, including the ecosystem function trade-offs, which lead to a decreased ability to maintain the ecosystem functions' production. Therefore, it is necessary to plan and manage Wetland City with an approach to resilience. However, few studies have dealt with ecosystem function trade-offs that lead to integrated urban planning and design. Moreover, it is hard to derive substantial strategies for enhancing the ecosystem functions and building the Wetland City's resilience. This study aimed to analyze climate change adaptive management strategy by simulating the resilient supply of ecosystem functions in Wetland City. First, we constructed Wetland City’s social-ecological system, which provides ecosystem functions that are traded off. Second, we simulated the resilient supply of ecosystem functions according to climate change adaptive management scenarios. The scenarios were selected by a scenario planning approach that allows us to integrate strategies to improve each ecosystem function. Finally, we determined an appropriate scenario that minimizes impacts of ecosystem function trade-offs reinforced by climate change and suggested adaptive management with resilience strategies for a sustainable Wetland City. This study can contribute to the guidelines for planning and managing Wetland City.
