How can art, science and institutional practices counteract the negative consequences of climate and ecological breakdown? How can these practices and ideas advance systemic change? Worlding Ecologies serves as an anthology of examples and wayward navigational tool, assembling eighteen authors exploring this question from their diverse backgrounds––as scientists, artists, philosophers, activists, theorists and curators––to rigorously approach urgent ecological challenges, including climate breakdown, pollution, biodiversity loss, environmental and social justice. This book emphasizes the fundamental role of art as a vehicle and support structure for intersectional ecological thought. Whilst navigating imagination, worlding-possibility, science fact, social justice and climate action, the book prompts a fundamental role for art to create the blueprints for regenerative and sustainable more-than-human worlds. Structured alongside three sections––Science and Climate Truth; Activism and Climate Justice and Social Justice in Institutional Ecosystems––Worlding Ecologies moves from fieldwork-taking to patchwork-making, unifying the arts with science, politics and ecology into a field of synthetic thought and commitment.
