ABSTRACT
One of the key debates in urban planning today is centred on problems of social inequality and spatial segregation within large metropolises. While it can be argued that urban structure and form have an important role in determining both quality of life and the efficient distribution of resources, it can also be argued that a sustainable city is more than its mere physical form. As cities grow in size and the monocentric form of large metropolises evolves progressively into a polycentric structure over time, the problems of social exclusion and fragmentation may be exacerbated.
