The dichotomy of urban restoration: wishes and effects
Oslo, the capitol of Norway, has the highest growth rate of all major cities in Europe, and residential areas are rapidly created from former industrial spaces. In 2015, a stream and pond were created from a previously culverted, sewage affected stream. The aim was to retain nutrients and pollution, and developing a blue infrastructure in a previously industrial area. Water chemistry and biota was sampled the first summer season, at seven sites along the stream, and a reference upstream. Preliminary results show that the stream and pond act as both a sink and source of nutrients. The biota generally improved from upstream to downstream sites, indicating self-purification along the stream. Phytoplankton measurements in the pond indicate that the system had not yet reached a stable state, and any real improvement in water quality is doubtful. Furthermore, municipal restrictions on water related activities limit the overall value of the project. We believe there is a need for more ecological knowledge in urban restoration projects, as they are insular in their purpose of being primarily open water sewage treatment plants, and blue, but no-touch, spaces in the urban scape.
