Toward cities without slums: Topology and the spatial evolution of neighborhoods.

ABSTRACT: The world is urbanizing quickly with nearly 4 billion people presently living in urban areas, about 1 billion of them in slums. Achieving sustainable development from rapid urbanization relies critically on creating cities without slums. We show that it is possible to diagnose systematically the central physical problem of slums-the lack of spatial accesses and related services-using a topological analysis of neighborhood maps and resolved by finding solutions to a sequence of constrained optimization problems. We set up the problem by showing that the built environment of any city can be decomposed into two types of networked spaces-accesses and places-and prove that these spaces display universal topological characteristics. We then show that while the neighborhoods of developed cities e
