A hierarchy of measures for infrastructure resilience – learning from post-disaster reconstruction in Christchurch, New Zealand.

Recent research into the concept of resilience has shown that it helps key players in urban development to assess and set priorities for resistance and recovery for disaster risk management. However, a competing issue within post-disaster recovery is managing the trade-offs between quickly restoring infrastructure services versus taking time to consider and consult on alternative options. Through an examination of the post-earthquake reconstruction in Christchurch, New Zealand, this paper considers infrastructure resilience by using a hierarchy of measures. This hierarchy shows how infrastructure resilience needs to be considered as a series of interventions in response to different levels of damage. It elucidates the varying nature of resilience measures, the decision-making processes required to implement them and constraints, chiefly in funding, that prevent wider application of such measures. This is an important consideration for defining and acting upon the opportunity for change created by a disaster. Furthermore, a broader examination of resilience in disaster risk management highlights that clarification is needed over what constitutes an appropriate response for community involvement in post-disaster infrastructure reconstruction.
