Step-by-step explanation:
The National Governors Association made significant contributions to the emergency management profession through the development of comprehensive emergency management, which includes the four phases of emergency management and the all-hazards approach. The four phases—mitigation, preparedness, response, and recovery—provide a framework for dealing with emergencies and disasters of all kinds.
The all hazards approach encourages planners and responders to consider a wide range of potential scenarios, ensuring a more flexible and effective response to various types of incidents, including natural disasters, terrorist attacks, and other catastrophes. Defining critical infrastructure is also important in this field, as it relates to ensuring the resilience and security of essential services and assets.
