Winner of the 2000 Lynton Keith Caldwell Prize, American Political Science Association "[The book's] assertion that violence and the environment may be linked, and its conclusion that most big developing countries appear to be hurtling toward more internal conflict, are too important and intriguing to be left to an academic audience."--John Stackhouse, Toronto Globe and Mail "This volume is for anyone with professional or deep personal interests in the relationships of natural resource management to economic development and human societies."--Joseph P. Dudley, The Quarterly Review of Biology "[A] comprehensible model linking environmental scarcity and violence."--Stephen P. Adamian, Boston Book Review "Important and intriguing."--John Stackhouse, Globe and Mail "Clearly written and forcefully argued, Environment, Scarcity, and Violence is an excellent work."--Biology Digest "Thomas Homer-Dixon ... has conducted extensive research on the links between environmental stress and violence in developing countries... The book addresses the fact that environmental scarcity is not in itself a necessary or sufficient cause of conflict. Homer-Dixon evaluates why some societies are able to adapt well to environmental scarcity while others are not."--Nikola Smith, Journal of International Affairs
