With origins in the late 1960s, a 'quiet revolution' in land use planning and control has taken hold across North America. First seen as a manifestation of the environmental movement, the revolution prompted governments at several levels to attempt to protect critical areas and vulnerable natural resources. Many of the most dramatic and far-reaching shifts in planning regimes have occurred in large-scale, environmentally unique or sensitive regions. It is these big places, looming large in the American and Canadian psyches, that are the focus of this edited volume. Each of the chapters reflects on the contemporary challenge of environmental and land use planning. Ten leading distinguished scholars here provide thoughtful analyses and critical insights into the processes and contexts shaping the innovative planning and policy schemes in seven regional landscapes.
