Located at the West coast of Norway, the city of Bergen is already habituated to a rough climate with wind, rain and flooding at high tide. Downscaled climate change scenarios predict that the city will be heavily exposed to the effects of climate change and consequently will experience an even rougher climate and more extreme climate events in the years to come. The adaptation efforts in the city of Bergen are organized partly through the traditional hierarchical structure of public government, and partly through a complex maze of different voluntary associations and networks including both public and private actors. This chapter explains how these two ways of organizing climate change adaptation have contributed to climate change adaptation in Bergen. It also looks at the interaction between hierarchies and networks in order to identify synergistic or adverse effects. The chapter is based on analysis of data from interviews and policy documents.
