Warren Karlenzig - Collective Intelligence: Cities as Global Sustainability Platform - TEDxMission

His delivery is stilted and controlled, but his ideas are important. We are entering a period of amazing and rapid urbanization, a move that dwarfs urbanization at the beginning of the 20th century. Karlenzig argues against low-density urban sprawl in favor of high-density approaches, which increases resilience and reduces resource needs.

I would like to hear Karlenzig in conversation with Marilyn Hamilton, author of Integral City: Evolutionary Intelligences for the Human Hive.

Karlenzig is founder of Common Current, and author of How Green Is Your City? The SustainLane U.S. City Rankings. 

Warren Karlenzig - Collective Intelligence: Cities as Global Sustainability Platform

TEDxMission - Social media and collaborative technologies--layered with smart systems combining geo-location data with human experience--will make cities the driving sustainability force in a dawning planetary era. Cities will anticipate new risks with rapid urban systems innovation based upon crowd-sourcing, virtual and physical communities, and transparent markets sensitive to full carbon and resource costs. Creatively leveraging collective intelligence for clean energy, low carbon mobility and sustainable food and water, the new urban grid will enable high local quality of life, lifelong learning and vibrant green economies.
