The Spatial Contract is a book that delivers a concise message: if we work honestly together, we can take care of our basic human needs. It focuses our attention on the reliance systems of food, shelter, health, mobility and education, among others, which are essential for communities to act, have agency and be free. Central to this book is its analysis of the processes required for the development, maintenance and repair of these systems, based on healthy spatial contracts. The authors expose our inability to resolve basic population needs in places across the global South and global North, or predominantly on the left or the right. They challenge scholars and practitioners to address this task by providing thoughtful reflections, clear tools, and a path of possibility.
