Climate Adaptive Delta Cities

Abstract

The climate crisis will require far-stretching changes to our urban systems, also called a transition. However, the direction in which our society will transition is still deeply uncertain. To become less vulnerable, cities and urban areas need to increase their adaptive capacity, establishing an evolutionarily resilient region. Delta cities in the Netherlands are governed through a decentralised and neo-liberal governance model, giving responsibilities for the long-term to local actors. As a result, climate adaptation relies on being integrated in local urban redevelopment projects to produce the necessary innovations that are needed for the transition.
In the Netherlands, post-industrial port sites are redeveloped into mixed-use residential areas which should have an innovative and adaptive character to function as pilots for the regional transition towards a climate adaptive system. Nevertheless, in many cases short-term responsiveness and econmic values get the overhand, reducing the innovative value of experiments and the contribution pilot projects make for the essential transition. This leaves redeveloped neighbourhoods and the delta region vulnerable to the effects of the climate crisis and is predicted to result in a chaotic transition from the existing to the climate adaptive system (Rotmans, 2021).
This urbanism graduation project therefore studies the following question: how can post-industrial port redevelopments contribute to the transition towards climate adaptive delta cities? Comparative case study research of cases in the Rhine-Meuse delta is used first to compose an understanding of mechanisms behind the integration of climate adaptation and industrial and societal transitions in post-industrial port redevelopment projects. Next, the case study lessons for adaptation are integrated with transition principles in a redevelopment strategy for a representative case and regional pilot for climate adaptation: de Staart in Dordrecht. Here, the Dynamic Adaptive Policy Pathways framework (Haasnoot et al., 2013) proves to be a promising methodolgy for making the complex and interdisciplinary transitions more insightful.
An urban design simulation for a section of de Staart shows how the policy pathways should be used in combination with an inclusive process, a spatial framework and a set of dynamic rules to esure that short-term actions contribute to the long-term transition pathway and adaptation under uncertain future contexts remains possible. The strategy for climate adaptive redevelopment of post-industrial sites shows that it can improve local liveability through its inclusive process and accellerate the regional transition by being connected in a regional network. The project shows promising qualities for bridging the gap between ambitions towards realising climate adaptive delta cities and it can be a valuable design and redevelopment strategy for application in practice. Nevertheless, applicability in different context than the Rhine-Meuse delta can be evaluated by performing similar research under different cultural contexts.
