This book deals with the constantly evolving, vast, and diverse field of nontraditional security. Nontraditional security goes beyond military security and focuses primarily on socioeconomic security. Its major concern is human beings rather than border or territory of the state. The book focuses on nontraditional securities such as human security, energy security, food security, environmental security, cybersecurity, health security, terrorism, drug trafficking, human trafficking, biological, and chemical weapons. All the nontraditional security issues are highly relevant for academics and policy makers as well.
