Stadsplanering i ett förändrat klimat Anpassningsstrategier och åtgärder mot skyfallsöversvämningar i Göteborg och Köpenhamn

Abstract

The aim of this report explores and analyzes how Gothenburg and Copenhagen implement strategies to deal with cloudburst flooding in a changing climate. Due to the changing climate cloudburst events will happen more frequently and more intensely, this will generate challenges to urban areas. Therefore, the focus of this report is to identify the most vulnerable environment in both cities, additionally how the cities work for climate adaptations and physical planning. The method is based on a combination of qualitative and quantitative approach. Gis- analyzes is produced to illustrate the identified area with the most risk for cloudburst floodings, in both Gothenburg and Copenhagen. The use of the qualitative approach made expert interviews possible, which generated a more subtle insight of knowledge. Using documation's and planning frameworks, the information was established for the work and planning for climate adaptation in both cities. The work of the report is based on theoretical frameworks that include urban resiliens and the Three Point Approach (3PA) which is analyzed in the results. The results indicate that both Gothenburg and Copenhagen possess vulnerable areas for cloudburst floodings. With experience of cloudburst event Copenhagen has created a more effective solution of climate adaptation through their cloudburst management plan. Gothenburg strategies are based on the cooperation between different actors, a limitation is that proposed adaptations strategies are not always being implemented. The study shows that effective management for cloudburst risks technical solutions, Clear distribution of responsibilities and collaboration between actors. The result indicates that cooperation is critical for creating sustainable urban climate adaptation.
