ABSTRACT
This chapter presents the study of security has shifted from an almost exclusive focus on the role of militaries, conventional weapons, and nuclear deterrence theory, to an expanded role includes a plethora of subjects previously identified outside the security studies umbrella. It focuses on the quantitative and qualitative analysis, pointing to the need for a continued study of the contemporary security environment. There is little consensus in literature on what security, let alone security studies, exactly entails. Many scholars argue that security should encompass only issues of armed conflict or military threat, while others argue that nonmilitary threats are of equal importance in considering the contemporary security agenda. The Global Trends and Transitions in Security Expertise: From Nuclear Deterrence to Climate Change and Back Again project is intended to provide an examination of the trajectory of Security and International Affairs studies over the twentieth and twenty-first centuries.
