UN-Habitat has released a new biannual review, State of the World Cities, at the World Urban Forum in Rio. The report finds that by 2050 nearly 70% of our global population will live in cities- a stunningly rapid shift. However, if this transition is not planned for appropriately most of these people will be living in megaslums- perhaps an even more pointed reminder of the need for sustainable development than CO2 reductions.
A host of other sustainable cities initiatives were announced at WUF, outlined by the folks at DIRT.
