Seasonality in recreation supply and demand in an urban lake ecosystem in Finland

摘要

Monetary valuation methods are commonly used to analyze recreation values of water ecosystems. However, most studies on water-related recreation values have not analyzed direct links between ecological elements providing recreation opportunities and user demands. Therefore, we implemented an ecosystem service approach to study human-nature interaction during the actual recreation visit to an urban freshwater site. We developed a conceptual model of local cultural ecosystem services (CES) to study interactions between recreation supply and demand. We were interested in seasonality of water-related recreation supply, and the different demands of summer and off-summer visitors. We chose urban Lake Kuusijarvi in the city of Vantaa, Finland, as our case study area, because it is a popular outdoor recreation area around the year. We identified 14 key elements of the supply of local CES and 22 socio-cultural values for the demand for local CES. We found little seasonal change in recreation supply, but the socio-demographic characteristics and demands of summer and off-summer visitors varied significantly. Demand was higher and more diverse during the summer season, while off-summer visitors were more specific in their demands. Moreover, some visitors feared that some socio-cultural values can be lost if the recreational use of the lake area increases. We discuss our findings in a theoretical context focusing especially on interactions between supply and demand of local CES at Lake Kuusijarvi.
