This course is designed to give students an understanding of the origin and evolution of security as well as to provide the theories and debates within security studies which can be used as a framework for analysing issues in international politics. In tracing the development of security studies, the course will seek to demonstrate the widening and deepening of the concept of security, which at the core will determine how it is being interpreted and studied. The scope of the course’s content captures traditional notions of state security as well as the unorthodox theories of security which have emerged in the post-Cold War era. It will focus on the offensive and defensive realist perspective on anarchy, the security dilemma, arms race, and offensive-defensive theory. The unorthodox theories of security focuses on the Copenhagen School (Securitization Theory), Social Constructivism, Critical Security Studies, Feminist Security Studies, Post-structural Security Studies and Human Security. It concludes with an important security threat affecting the Caribbean – drug trafficking – and explores the impact of globalisation on this problem. Theories and Concepts in Global Security integrates well into the Programme on International Relations as the nature and scope of security issues remain core features fornation-states and for their global relationships. Further, it advances the University of the West Indies mission by utilising pedagogy to meet the critical regional need of understanding Caribbean security within the wider global context. This process is an important component in fostering Caribbean development.
