Another website I came across is WorldChanging.

"WorldChanging.com works from a simple premise: that the tools, models and ideas for building a better future lie all around us. That plenty of people are working on tools for change, but the fields in which they work remain unconnected. That the motive, means and opportunity for profound positive change are already present. That another world is not just possible, it's here. We only need to put the pieces together."

The site is full of very interesting articles and ideas on making the world a better palace.

There is a whole section on urban living and cities:

"We live on an urban planet. For the first time in history, a majority of us live in cities. How we grow those cities, how we build neighborhoods, how we provide housing, how we choose to get around, how well we incorporate nature into the places we live - these are the challenges that will largely determine our future.

And with millions and millions of people moving every year from the countryside to the city, all of these difficulties seem even more insurmountable. Appearances, however, can be deceiving. For, along with the boom in urbanization, we're seeing a boom in urban innovation. Simply put, we're getting better at building better cities."
