During his three terms as mayor of Curitiba, Brazil in the 1970s and ‘80s, architect and urbanist Jaime Lerner transformed his city into a global model of the sustainable and livable community. From the pioneering Bus Rapid Transit system to parks designed to catch runoff and reduce flooding, and the creation of pedestrian-only zones, Lerner has been the driving force behind a host of innovative urban projects.  This book celebrates these “pinpricks” of urbanism—projects, people, and initiatives from around the world that ripple through their communities to uplift city life.
