The role of stream ecosystems in urban planning - A case study from the stream Rekolanoja in Finland

摘要

Purpose - Urban stream ecosystems have often been seen as channels of water flow rather than as the valuable parts of an urban green space system providing ecosystem services. The study seeks to address the importance of urban stream ecosystems from the perspective of urban ecology, human health and social well-being in the context of urban planning. Design/methodology/approach - The case study area is the Rekolanoja stream ecosystem in the City of Vantaa, southern Finland. The data from the case study area were gathered from existing ecological studies and by conducting semi-structured interviews, a resident inquiry and a writing contest. Findings - The results from the Rekolanoja case show that intense management of the streamside vegetation and treatment of the stream channel in construction projects have decreased species richness and diminished valuable streamside biotopes. However, the stream corridor can function as an important recreational and educational element within the local green space network and thereby become a symbol of local identity. Practical implications - Planners, decision-makers and other interest groups can use the findings from this study in determining the values of small urban stream ecosystems in urban development. Originality/value - The Rekolanoja case indicates that planners and residents see the value of such an aquatic element as increasingly important for urban biodiversity and ecological corridor functions, as well as for local human health and social well-being, e.g. recreation and stress relief. Future land-use decisions will show whether a genuine change in the values and thinking of planners and decision-makers is taking place.
