For some time now, the prospect of water scarcity has been an issue of growing international concern, but one which governments, globally and particularly in the Indian sub-continent, have been reluctant to address. Increasingly, however, the social and economic impacts of water shortage are becoming apparent, and their longer-term implications for domestic and international security are attracting attention. Binayak Ray's book provides a timely examination of the major features of the looming crisis in the sub-continent. Drawing on his considerable experience as a bureaucrat, an aid official, and a scholar, Ray details the emerging problems in historical and contemporary context, and discusses appropriate policy responses. His study makes a valuable contribution to debate on this important topic.
