Discussion of ‘A research agenda on systems approaches to infrastructure’ by Jennifer Whyte et al.

ABSTRACT Research focussing on urban infrastructure is much needed. The original paper reviews a number of initiatives for this. The discussion suggests possible additions such as inclusion of network theoretic ideas, a focus on the importance of clearly defined system boundaries, further developments of resilience theory, and issues related to recovery from, rather than response to, major natural disasters, where intertwined physical and management issues can lead to significant system problems.
