New realities: Constancy of crisis and poly-crisis for public administration

This chapter reviews the key components of good crisis management, shares 57 crisis events, and outlines that crisis types and country case studies are included in the Handbook. We contribute to the development of crisis management understanding by also defining polycrisis, the polycrisis constant, and their importance for modern emergency management and crisis management scholarship. This includes a brief summary of the intellectual history of the polycrisis concept and our concern about the absence of polycrisis studies in public administration and public policy. The chapter continues by summarizing each Handbook chapter and their contributions to crisis management studies. In conclusion, we suggest the necessity of research on crisis, polycrisis, and the polycrisis constant.
