Peak Oil & Permaculture

Currently Authors Richard Heinberg & David Holmgren are on an Australian Tour. Last Thursday I left work early and drove up to the Kuringai Town Hall, 1186 Pacific Highway, Pymble (Sydney).
I got their a bit late.

I saw the end of Richard's talk. Very interesting, he was talking about the Oil Depletion Protocol.

David Holmgren's talk start with the history and stages of permaculture over the late 30 years. He then covered the history of energy/resource use, population and pollution and how their trends & magnitude parallel each other. He then outline 4 possible future scenarios: Techno-Explosion, Green-Tech Stability, Earth Stewardship/Creative Descent & Atlantis (Collapse). David stated why he think Creative Descent is the most likely outcome.

David listed some aspects and (permaculture) practices that Creative Descent would incorporate. Then the seven domains of permaculture action where covered.

We then, being in Sydney, look at Peak Oil and Creative Descent applied in suburbia. The example used was a 4 house street, starting in the 1950s. David followed its changes & total population (thus population density) over the late 50 years. He then outline measures that would lead to lower energy/recourse use and greater population density (the holy grail of town planners for the last 20+ years).

There was also a Q&A session. Didn't get a chance to ask my question. I asked David, privately, afterward. I'll write up the a post, and get David's ok to post it.

Then a long drive home, but I did bus it to work for most of the week.
