It's TEDx season. Between now and mid December, 100?s of independently organized TEDx events will be held throughout the world, including here in Vancouver as well as Phoenix. For those unfamiliar with TEDx events, here how the main TEDx site describes them:

Created in the spirit of TED's mission, "ideas worth spreading," the TEDx program is designed to give communities, organizations and individuals the opportunity to stimulate dialogue through TED-like experiences at the local level. TEDx events are fully planned and coordinated independently, on a community-by-community basis.

As a TEDx alumnus, I have a special place in my heart—and mind—for these local events. Sure, the main TED events boast an impressive array of the world's top minds, but the diversity that is on display at TEDx is unparalleled. The is especially true when it comes to talks about urbanism and cities. While was challenging to simply find five TED talks on cities, I had the opposite problem with TEDx; my challenge here was narrowing it down to just 5. In the end I failed to narrow the list to simply 5 and had to throw in an extra one.

Here are 6 of my favourite TEDx talks on cities.

Dan Burden presents the case for creating communities that are centered on people and not cars. He identifies the benefits to the community in terms of both vitality and economic well-being. As a leading expert in his field of creating livable communities he talks about the processes he uses and the results of his many projects.

Christian Sottile is principal of an urban design firm based in Savannah. His work has received over 25 awards, including an international Charter Award from the Congress for New Urbanism, and awards from the American Planning Association and the Georgia Trust for Historic Preservation.

Using insights drawn from his work in business, entrepreneurship and social change, as well as modern GIS data, Naheed Nenshi explores the challenges of how a modern city like Calgary grows, and what some of the implications are for creating inclusive communities.

A brief look at trends shaping the way we will live and how cities must adapt to be successful.

Even with the extra video I included, I had to leave out several great talks.  If i missed your favourites, please let me know in the comments
