This book examines the evolving intersection of urban development, ecological theology, and technological transformation across diverse spiritual traditions, including Hindu, Sikh, Islamic, Catholic, and Buddhist perspectives. In an age defined by digital urbanism, artificial intelligence, and environmental crisis, this volume explores how sacred values and ecological ethics are being reinterpreted within rapidly changing urban environments. It critically engages with the tensions between technological solutionism and ecological wisdom, questioning how urban technologies shape spiritual relationships and theological understandings of creation and stewardship. Through conceptual frameworks such as the SIMRAN Framework, Nature-Maker Approach, and emerging ideas like smart theology and nAIcolonialism, the book advances a transdisciplinary dialogue between faith, sustainability, and innovation. It will appeal to scholars and practitioners in theology, sustainable architecture, urban planning, and environmental humanities.
