The politics of crisis terminology is rarely examined directly. Crisis is an “umbrella,” under which resides a multitude of terms such as accidents, emergencies, fiascos, disasters, and catastrophes, as well as variations such as natural disasters, transboundary crises, and mega-crises. Yet the sheer diversity and frequent ambiguity among terms reflects the “politics” of how societies and political actors seek to cope with and address extreme events, which often pose a mixture of threat and opportunity. Central to an understanding is how (a) different terms are means of framing issues such as the scale and causes of the crisis, (b) crisis terms are part of governing strategies, and (c) nongovernmental actors (opposition parties, media, lobby groups, social movements, and citizens) can seek to influence government. A pivotal point in developing an understanding of crisis terminology is that rather bemoaning the lack of singular meanings for crisis and associated terms, or criticizing actors for “abuse” of the terms, one should recognize and accept that complex and contested crisis language and definitions are in themselves manifestations of politics in political societies.
