As we find ourselves in the midst of yet another crisis that undermines the ecological, political and economic bases of our lives, alternative forms of organizing are gaining renewed attention, and calls for a critical engagement with them are more urgent than ever. In response to this imperative, the conference explore the current challenges and opportunities opened up by activist forms of organizing. In particular, the conference aims to expand on how these alternatives challenge dominant power relations and prefigure a more democratic, ecologically sustainable, and socially just society in the here and now.
