Biophilic Cities redefines what it means to create truly sustainable urban environments—placing nature, not just efficiency, at the heart of the vision. Tim Beatley, a longtime advocate for greener cities, argues that while efforts like public transit, renewable energy, and efficient buildings are important, they often overlook something essential: the human need for connection with the natural world. Rooted in the biophilia hypothesis—the idea that people are wired to seek relationships with nature—Beatley makes the case that cities must do more than be livable; they must be deeply, deliberately connected to natural systems. A biophilic city, he explains, is not only biodiverse but designed to celebrate and integrate natural forms and processes at every level—from buildings and streetscapes to urban planning and regional design. Drawing on inspiring case studies from cities around the world, Biophilic Cities explores how urban areas are embracing nature through green roofs and walls, sidewalk gardens, ecological corridors, and citywide greenspace networks. Beatley shares the stories of planners, architects, and everyday citizens who are reshaping cities into places where people and nature thrive side by side. This book is both a call to action and a guide for anyone seeking to transform grey, hardscaped environments into vibrant, restorative, and resilient urban ecosystems.
