The close of the last millennium saw the development of cities in the developing world being radically shaped by the intrinsically related processes of urbanization and globalization.
Neither of these phenomena is new — what is unprecedented is their pace and scale. Indeed, urbanization processes in most developing countries are intensifying. This poses immense challenges for governments at all levels. These are rapid urban population growth and the urbanization of poverty.
The latter is manifested most conspicuously in the proliferation and expansion of slums and informal settlements, which are home to a growing proportion of urban dwellers in developing countries. It presents a major challenge to the international community.
