Contemporary Security Studies provides an introduction to Security Studies. It features a wide breadth and depth of coverage of the different theoretical approaches to the study of security and the ever-evolving range of issues that dominate the security agenda in the twenty-first century. In addition to covering a large range of topical security issues, from terrorism and inter-state armed conflict to cyber-security, health, and transnational crime, the sixth edition features an examination of popular culture and its implications for security, as well as coverage of the on-going COVID-19 pandemic. Throughout, readers are encouraged to question their own preconceptions and assumptions, and to use their own judgement to critically evaluate key approaches and ideas. To help them achieve this, each chapter is punctuated with helpful learning features including ‘key ideas’, ‘think points’ and case studies, demonstrating the real-world applications and implications of the theory.
