The present volume examines the case for broadening the scope of security by breaking the rigidity brought about by traditional forms of dominant state-centric and military based security concepts and their determining matrices. The main thrust of this study is on three very critical areas, viz., (i) environmental security, (ii) food security and (iii) energy security. It deals with how gains from effective management of human security parameters get translated into enhanced security both at the macro and micro levels. In doing so, the study endeavors to unfurl a new framework of concerns, complexities and constituents of human and national security linkage. This enhances the possibility of arriving at a collective and comprehensive notion of security on a national and sub-national basis, away from state-centric and threat perception-dominated determinants of security. This book should help experts and scholars of security issues understand new dimensions of national security and should this happen the book will have made a major contribution in the study of security issues.
