Importance-satisfaction analysis of cultural ecosystem services of multifunctional landscapes designed for stormwater management

The multi-functional landscapes for sustainable stormwater management play a significant role in providing various benefits on the environment, aesthetics, education, economy, etc. through the cultural ecosystem services, which have been underestimated by both the professionals and the public, due to the difficulty in their interpretation and quantification. The Importance-Satisfaction Analysis (ISA) makes it easier by evaluating the cultural ecosystem services with human's perception, and was tested with the multi-functional landscapes for stormwater management in this research. The results show that aesthetic value, recreational / eco-tourism, and sense of place are the most valued cultural ecosystem services. Those cultural ecosystem services with a gap between their perceived importance and the public satisfaction with their delivery are also identified. ISA can discover the public's perception and expectation of the stormwater management landscapes, which helps the decision-making about their improvement a lot.
