The momentum of urbanization and its impacts are so massive that we must face up to this trend. In view of the existing cognitive, technical, economic and institutional path dependencies, a policy of business as usual – i.e. an unstructured, quasi-automatic urbanization – would lead to a non-sustainable ‘world cities society’.

The demography of cities in the 21st century will be shaped, to a large extent, by migration. This paper argues that the rights-based approach to urban policy advocated in the preparatory work of Habitat III, the UN Conference on Housing and Sustainable Urban Development to be held in October 2016 in Quito, Ecuador, may not be conducive to this goal. The approach lacks a contextual and dynamic... Read more
