Sure. Let's provide a little bit of context. Transitions is a global effort started by Rob Hopkins. Rob was a permaculture instructor, and the more he learned about Peak Oil, he figured that it would be a great way to teach permaculture to deal with the effects of Peak Oil. In effect, the Transition Initiative focuses on the effects of Peak Oil, which includes "global weirding"- my preferred phrase to describe the changes of climate- as well as the economic crisis that would be created by a lack of easily available cheap energy.
But the underlying theme of the Transition Initiative is the creation of resilient communities. Very few people know that the first American city to have a Transitions "Great Unleashing" was Sandpoint, Idaho- not exactly your liberal mecca. There was a mixture of liberals and conservatives invovled in the project, with one conservative saying, "I don't particularly believe in global warming or Peak Oil, but this is simply the right thing to do." As for Transition's local history, I was personally involved with the City's Peak Oil Task Force. During this process, we looked around for models of neighborhood resiliency to deal with Peak Oil. A friend of Hopkins came to Portland and did a presentation about the Transition Initiative. It was exactly what we were looking for. The Portland Metro region is all ready a fairly advanced transition area, carrying out a lot of stuff that Transition groups all over the world talk about- gardens, bike culture, the efforts of City Repair. All of these efforts are doing great work in Portland. At the same time, a model designed for a town of 10,000 will only be scaled up so high. I should offer a cheerful disclaimer, however, and that is to acknowledge that the Transition Initiative is very much an experiment, and there is no guarantee that these efforts will succeed in dealing with life after Peak Oil. However, there is another acknowledgement that if why try to do everything by ourselves, these efforts will be too little. At the same time, if we wait for government, then it will be too late.
