Disasters and public health emergencies are inevitable and can happen anywhere and anytime. However, they can be mitigated and their impacts can be minimized by utilizing appropriate measures in all four different phases of disaster management, i.e., mitigation and prevention, preparedness, response, and recovery. Several factors are crucial for achieving successful disaster management. In the mitigation and preparation phase, all risks should be reviewed and new ones should be added and analyzed carefully to propose proper solutions and plans. In the preparedness phase, the ability and knowledge of each organization and all individuals in the management system should be tested and evaluated to ensure good readiness in responding to an emergency. Furthermore, plans should be available at all levels of the emergency chain of action to cope with all issues in the response and recovery phases [1,2]. This Issue of Sustainability aimed to cover emergency and public health crisis management from a multiagency perspective, by discussing lessons learned, introducing new ideas about flexible surge capacity, and showing the way it can practice multiagency collaboration.
