This comes from "Smart City Radio" - a series of programs on urban planning and how a city works. Click title for a link to the page where you can hear the show on how cities can be successful, sustainable entities. A lot of discussion about how density is the key to sustainability and how iconic landmarks are important for a city's signature (hmmm.) This is really from a worldwide perspective and is eye-opening.
The second interview talks about the economic development potential in green jobs and how cities are responding to the threat of global climate change. Surprisingly, they don't see much advantage by a city having its own utility in ways to encourage resulting industries and cites Austin, Texas as an example.
This episode aired on May 13, 2009.
I'll make it a point to look over some other shows and share them from time to time.
