Why are food scares become so common? Whose voices count in decisions affecting the landscapes where we live? Will we soon be wars over water? What makes people protest outside international trade meetings? These are just a few of the questions that are explored in "Contested Environments". By bringing together perspectives from science, social science, technology, and humanities, the book addresses in a uniquely interdisciplinary way why environmental issues are so often controversial. Other features include the detailed examination of a wide range of topics from specific disputes such as those around GM crops, national parks, energy policy, water supply, and international trade to broader debates like environmental justice, economic valuation of environments, and the media, the promotion of integrative thinking through the book wide use of the concepts of value, power, and action, the inclusion of frequent activities to encourage readers to develop both their appreciation of particular issues and generic skills, the rich illustration of the text with examples from around the world. The book is part of a series entitled "Environment: Change, Contest and Response". The series forms a significant part of an interdisciplinary Open University course on environmental matters. The other books in the series are: "Understanding Environmental Issues"; "Changing Environments"; and, "Environmental Responses".
