Posturban reveals why the future cannot remain urban. Linking climate breakdown, inequality, and democratic erosion to an urban paradigm rooted in a patriarchal, discriminative divide, it calls for a radical shift towards resilient, decentralised, and ecologically rooted ways of living. Through a transdisciplinary critique of urbanisation’s ties to the Promethean foundations of capitalism, consumerism, and technocratic governance, the book shows why urban-centred solutions fail—and what can replace them. It introduces alterRural, Epimethean modernities that restore faith in nature and humanity: frameworks uniting ecological care, community autonomy, and cultural resilience into strategies for systemic change. It demonstrates how reviving peasant values and fostering a plurality of place-based communities can lead towards sustainable, equitable, and life-affirming ways to inhabit Earth. Written for engaged citizens, activists, policymakers, and scholars interested in more equitable and sustainable ways to organise society, Posturban is for anyone ready to challenge the future of cities and explore viable, hopeful alternatives.
