Race in the Anthropocene provides a radical new perspective on the importance of race and coloniality in the Anthropocene. It forwards the Black Horizon as a critical lens which places at its heart the importance of ontological concerns fundamental to problematising the violences and exclusions of the antiblack world.At present, multiple new approaches are emerging through the shared problem field of Anthropocene thought and policy, offering to save not just the world, but the practice of governance, the business of Big Data, the progress of development, and the dream of peace. It is against this backdrop that Race in the Anthropocene unsettles not just the already shaky foundations of modernity but also the affirmative visions of its critics, by directing our gaze to how race and coloniality are baked into the grounding concepts of international thought.This book is essential reading for students of International Relations, particularly those interested in international politics, security, and development. It is also of relevance for those interested in contemporary social, political, and environmental debates and policy practices.
