Based on this blog post. This is an established network of community-scale re-thinkers of the economic status quo, initially stimulated by "peak oil" awareness.
Quote from www.transitionnetwork.org:
What is a Transition Initiative?
It's a place where there's a community-led process that helps that town/village/city/neighbourhood become stronger and happier.
It's happening in well over a thousand highly diverse communities across the world - from towns in Australia to neighbourhoods in Portugal, from cities in Brazil to rural communities in Slovenia, from urban locations in Britain to islands off the coast of Canada. Many of these initiatives are registered on the Transition Network website.
These communities have started up projects in areas of food, transport, energy, education, housing, waste, arts etc. as small-scale local responses to the global challenges of climate change, economic hardship and shrinking supplies of cheap energy. Together, these small-scale responses make up something much bigger, and help show the way forward for governments, business and the rest of us.
