Urban and infrastructure resilience: Diverging concepts and the need for cross-boundary learning

The concept of resilience has attracted considerable attention in policy and research communities in the fields of both urban and infrastructure development and governance. Resilience has been framed as a boundary concept bridging different communities of knowledge production and practice. However, a closer look at the joint enterprise, the shared repertoire, and the mutual engagement of respective knowledge communities in urban and infrastructure research and planning practice reveals that resilience is understood and dealt with in rather diverging ways. This paper explores some of these divides, then argues that differences in knowledge production can induce somewhat disconnected policy outcomes and governance approaches which consequently weaken cities' ability to address current and future challenges. Therefore, we call for more interaction and cross boundary learning between respective knowledge communities.
