The new edition has been extensively revised to include up-to-date explanation of green political theories and traditions and the debates that shape action on the ground. It contains an expanded discussion of environmental movements that work in the Global North, the Global South and transnationally. Greater attention has been given to the roles of corporations, non-governmental organizations, the media, consumers and citizens in order to reflect the changing nature of environmental governance. The text also focuses throughout on debates surrounding the concepts of environmental security, environmental justice and environmental citizenship. The authors examine the institutional responses of parliaments, administrative, legal and electoral systems; the more informal politics of social movements; and the politics of markets and the corporate sector as they respond to (or resist) the greening of societies. This engaging text has been fully updated to offer readers a greater understanding of international, national and local environmental politics as well as expected future developments at all levels. continues to use illustrative examples of conflicts, people and events spanning North and South America, Europe, Asia, Africa and Australia, giving it global perspective and relevance. Each chapter includes questions for debate as well as a list of key words and resources for independent research. This successful textbook remains a key resource for undergraduate and postgraduate studies across politics, environmental studies, development studies and human geography courses.
