In the large cities in the developing world, only a privileged minority of the population finds access to land and housing through the commercial market. Mushrooming ‘irregular’ settlements are filling the gap but are themselves beset by deficiencies and insecurity. The paper [on which the presentation is based on] argues that the failure of formal markets is systematic and structural, and that attempts to open them up for the poor have fallen short of overcoming these inherent limitations. In order to mitigate the widening gap between gated communities and ghettos, government intervention needs to be much smarter than the present mixes of negligent tolerance, brutal eviction, market-fundamentalist privatization, and populist titling.
