Environmental movements and their activities are studied from various angles, by different methods, and at different levels. While both detailed studies on single incidents of conflict and broad overviews of movements are available, relatively little work has been done at the intermediate level between these extremes. We argue that it is fruitful to engage at this level by undertaking comparative analysis of environmental campaigns. Such studies could help deal with inconclusive observations and findings on the changes of environmental movements during the last three decades. We hypothesize that indeed environmental activism has changed remarkably. By and large, conflicts are no longer marked by a relatively simple constellation of one challenger facing one target or opponent. Instead, we find a complex web of involved actors reaching from local to international levels. These actors tend to form broad alliances, and to link on different issues. Also, their activities are not restricted to only one arena or strategy but involve all available channels, arenas, and action repertoires to have an impact. Quite often, we observe loose coalitions of groups that act in an implicit division of labor, thereby playing on their respective backgrounds, foci, and experiences. Given the variety of actors, their organizational forms and tactics on the one hand and their different contexts on the other, it is unlikely that a common pattern of conflict will emerge across various issues and geographical areas. This is all the more true when comparing environmental conflicts in the Western and Non-Western world.
