The new divided city? Planning and ‘gray space’ between global north-west and south-east

The ‘gray spacing’ of most cities has also blurred the neat dichotomy between the global north-west and south-east in two major ways. First, the phenomenon of spreading informalities, which originates in the south-east, has long ‘infiltrated’ to cities of the north-west, mainly in the form of undocumented migration, temporary populations and growth in unplanned development. Second, the post-colonial f low of urban and planning knowledge, traditionally from the north-west to south-east direction, has now been partially reversed. Knowledge and concepts gained from the rich experience of the global peripheries is now used to understand and manage cities of the global core.
