‘A shape is cut at the edges, not the center. For planning, the practice, pedagogy, and knowledge of city building have long been shaped at the edges of urban life among marginalized communities. Through struggle and practice, resistance and insurgence, and daily care, these communities produce ways of knowing and building that have always shaped cities despite (not because of) what is taught and advocated, what is legitimized and justified, in planning institutions at the center. This co-edited volume, composed of chapters co-authored with community partners, exemplifies anticolonial knowledge co-production, bringing the excitement of shapes formed at the edges of urban communities across the world, along with the refusal of despair and a radical hope for a different planning. Decolonizing Planning: Power and Knowledge in the Informal City is an important book for all who refuse to accept planning as it is and who recognize how anticolonial insurgent planning practices are re-shaping the field.’
