Doherty, B.Doyle, T.2007-07-102007-07-102006Environmental Politics, 2006; 15(5):697-7120964-40161743-8934http://hdl.handle.net/2440/36050© 2006 Taylor & FrancisThis introduction considers three themes that recur across the various contributions to this collection. The first is the nature of borders and how these have been affected by the increase in transnational collective action and the growth in the power of transnational institutions. The second is the distinction between environmental movements and the social movement forms of environmentalism: meaning that not all forms of environmental movement are social movements. The third is the evidence of the diversity of environmentalisms, which leads us to identify three principal kinds of environmental movement, the post-material movements strongest in the United States and Australia, the post-industrial movements that are strongest in Europe and the post-colonial movements of the South.enJournal article002006189510.1080/096440106009371320002422943000012-s2.0-3375008270751970
