Types of cluster adaptation to climate change. Lessons from the port and logistics sector of Northwest Germany

In this article, we argue that sectoral adaptation efforts to climate change, e.g. of the ports sector, are also struggles to reshape economic space according to sectoral needs. Addressing globalisation, the effects on economic spatial hierarchies among regions and the active promotion of regionalisation are seen as important. Applied to the port industry, this allows approaching the fierce competition among European north range ports from an action- and power-oriented perspective. Climate adaptation of ports is predominantly referred to as technical responses to extreme events (e.g. coastal protection). A differentiated conceptualisation (based on still ongoing research), however, also addresses impacts on specific elements of the transport chain, and effects on the spatial function of a port (e.g. the changing competitiveness within the European port system). Hence, the ability of a specific port to adapt will also encompass the management of regional target conflicts, and of multi-level relations. Thus, climate adaptation becomes part of positional struggles in spatial hierarchies among regions and of conflicts about political priorities within them. At the same time, the limits of exclusively regional approaches in addressing sustainability issues without higher level support become evident. The article gives an overview of the literature on climate adaptation and its application to ports and provides a preliminary typology of forms of sectoral adaptation to climate change.
