We are living through a world-rattling ecological inflection point, with an unprecedented consensus that capitalism is leading humanity into a social and ecological catastrophe and that everything needs to change, and fast. Thankfully, radical environmental movements have forced the question of “system change” to the centre of the political agenda to make way for a just and livable world. Insurgent Ecologies takes readers on an inspiring journey across key sites of ecological crisis and contestation, showing how revolutionary politics can emerge from the convergences between place-based, often disconnected struggles. These engaging essays speak to longstanding debates in political ecology around how to advance transformations in, against and beyond capitalism. The collection starts from the belief that the environmental struggles taking place across the Global South and North are a necessary component of such transformations. The book presents unique stories of the visions and strategies of struggles organized around sovereignty, land, climate, feminisms and labour, written by scholar-activists rooted in territories around the globe, offering locally grounded yet global perspectives. Each story reflects on how to build solidarity and comradeship across diverse struggles and how new political subjects and transformative collective projects for social-ecological justice are created.
