This book explains how to reform the anti-ecological biases in our current frameworks of environmental governance, planning, decision making and design – and suggests how to make these changes. Cities can increase both the ‘public estate’ (reduce social stratification, inequity and other causes of conflict, increase environmental quality, wellbeing and access to basic needs, etc.); and the ‘ecological base’ (sequester more carbon and produce more energy than used during construction and operation, increase ecological space to support ecological carrying capacity, ecosystem functions and services, restore the bioregions and wilderness, etc.).
