This handbook’s contributions signal the importance of degrowth across multiple disciplines and practices. Along the way, they grapple with some of the most critical questions, ideological assumptions, policies, and social struggles of our time. The handbook approaches degrowth as a loosely knit and developing set of interdisciplinary propositions about what it might take to achieve a world of human and non-human flourishing. Contributors explore, challenge, and critique degrowth’s propositions and its prospects of shaping scholarly agendas, policy frameworks, and social movements. Essays consider degrowth from a variety of empirical and theoretical vantages, including urban design, architecture, political economy, political ecology, critical geography, and political theory. This integrative approach, at once critical and constructive, aims to preserve for readers the sense of possibility that has drawn people to degrowth scholarship thus far.
