How to develop urban resilience? Marie-Christine Therrien and her colleagues propose a new research agenda and a policy challenge on urban resilience. The authors argue that researchers and practitioners need to work together to better understand the transformative capabilities of cities, mobilize partners and develop new forms of governance. The research-agenda is published in Journal of Contingencies and Crisis Management. This publication is the result of a co-construction project between practitioners and researchers funded by the Social Sciences and Humanities Research Council of Canada (SSHRC).
