The newly released UN report "State of the World's Cities 2008/2009: Harmonious Cities". Its preamble: "Half of humanity now lives in cities, and within two decades, nearly 60% of the world's people will be urban dwellers.

He describes the chasm between wealth and absolute poverty that has been exacerbated since the earthquake. He writes of the "surreal contrasts along the streets above Port-au-Prince's central districts. People in tent camps reeking of sewage are living in areas where prosperous Haitians, foreign aid workers and diplomats cone to spend their money and unwind. Often, just a gate and a private guard armed with a 12-gauge shotgun separate the newly homeless from establishments like Les Galeries Rivoli, a boutique where wealthy Haitians and foreigners shop for Raymond Weil watches and Izod shirts".

Equity and sustainability?
