Disasters and the theory of emergency management are vibrant subjects for scholars. Researchers have focused on a variety of topics, including the definition of disasters, human behavior in extreme events, the nature of emergency management, ways to make the profession more effective, the pros and cons of various paradigms, and new areas of research. In studying these subjects, scholars have employed a variety of methods, including observation, field research, and comparison, among others. Findings from research reveals that humans are responsible for disasters and that vulnerability must be reduced. Studies reveal that antisocial behavior is less likely to occur than more common activities to support victims of disasters. The principles of emergency management have been elaborated, and scholars have argued that the phases of disasters are more complex that initially meets they eye. Research also reveals that bureaucratic approaches to emergency management are based on false assumptions and are too rigid. Scholarship also explores how to make emergency management functions more effective, and a number of articles have been written to explore paradigms to guide research and practice. Theoretical work on disasters and emergency management has examined planning, improvisation, and spontaneous planning. Research has also explored humanitarian logistics, the use of social media, the scholarship of teaching and learning, cultural competency and the culture of preparedness. Going forward, more research is needed on the complexity of disasters and the use or impact of technology in emergency management. A greater understanding of public health emergencies is warranted due to the challenges of Covid-19.
