Neither Landscape Urbanism nor New Urbanism....Planetary Urbanism?

from Alex Steffen

New Urbanism, more hardcore urbanists have long charged, can end up being just “sprawl in drag.” Landscape Urbanism, unless it addresses the physics of underlying systems (transportation, housing, manufacturing), threatens to be just “sprawl in a pretty green dress”.

I’d like to see a whole different approach, one which starts from the scope, scale and speed of the changes we know we need to make, and backcasts from that transformation as the basis of any sound urban thinking. Planetary urbanism. (emphasis added)

I am mystified by Alex' call for “Planetary Urbanism.”  I hope he can offer an example of what that means? Just a hint?
