Acknowledging the importance of non traditional security in the wider debate, this book looks at one significant aspect namely, environmental security. The book discusses different issues of theoretical and practical import through various chapters that deal with the general need for study on human and environmental security, its degradation due to a variety of factors like climate change, war, pollution and resource utilisation. Moving from a regional South Asian focus the book narrows down to specific cases within India and the region at large to highlight the widespread effect anthropogenic factors have had on environmental security. A diverse set of articles from many authors has meant a comprehensive perspective on a vital global and national concern.
