Designing intermediate community use during Brownfield phytoremediation in the post-industrial urban redevelopment project : a Case Study in Nyhamnen, Malmö

Sammanfattning: Malmö, once flourished with industries, has been transitioning since its decline in the 1980s. The redevelopment of Nyhamnen, one of the post-industrial areas, started in 2018 to accommodate the expected increasing population until 2050. The City of Malmö focuses on redeveloping within instead of expanding the city. Land reuse is efficient; however, there is an issue of contamination from previous industrial use. The risk classification phase 1 of MIFO, A Methodology for Inventory of Contaminated Areas, divides brownfields into four categories. The two highly contaminated groups become the target for remedial actions, and the two less polluted groups are often left behind. It leads to moderately contaminated sites, the highest in case numbers, being left untouched. Phytoremediation, in-situ remediation utilising the plant mechanism to absorb or decompose contamination, is an environmentally and economically friendly method. It may take an extended application period, depending on the condition. Hence, this thesis investigates phytoremediation's applicability in a long-term redevelopment plan. Furthermore, this paper explores the potential of community creation through phytoremediation and community gardening as an instance of bottom-up initiation. The long-term application of phytoremediation may allow community development in a newly developing area. Container community gardening, which does not choose on-site soil conditions, is flexible and contributes to community formation that individualisation alienated. Communities in society are fundamental in supporting autonomous behaviour and being active citizens. By understanding behaviours, sense of place, communication and the supporting system, Landscape Architecture may encourage forming a space for communities. A design as an example of intermediate community spatial use during phytoremediation conducts on the brownfield Medusa 1 in Nyhamnen. There is a potential for phytoremediation’s application in Nyhamnen, Malmö, in line with the aims of the City of Malmö and the County Administrative Board of Scania, despite the difficulties of project planning in terms of time and technique. Community gardening, an example of intermediate use of brownfields, may contribute to community formation and promote active citizen engagement by supporting their autonomous behaviour.
