The book identifies the sources and nature of threats to people belonging to ethnic groups and conceptualizes human security in a manner that addresses the inadequacy of the traditional approach. It conducts an analysis on ethnicity- and non-ethnicity-induced human security problems in the CHT of Bangladesh and the Sindh Province of Pakistan, as important areas of human security. This work deals with threats stemming from ethnicity and the resultant conflict thereof in the CHT and in Sindh. The book, therefore, conceptualizes the concept of human security to mainstream it into security discourse. The book is definitely destined to result in a positive contribution to security studies.
