Yesterday, on Geoff Lawton's daily emails, there was an article about the USDA's unofficial support of permaculture, and what intrigued me the most about the article was that the agricultural economist Geoff Lawton spoke to said about agroforestry and permaculture: "They're the same,". For more information on this, Grant Schultz manages an email to teach permaculturists how to receive help from the USDA. I brought this article up because it made me think about the other forms that permaculture could take on.
I think the way I remember hearing Geoff put it was something like this:
Permaculture is like a clothing rack. Things like agroforestry, aquaculture, integrated orchards and paddock shift grazing are all hangers on the rack. In other words, all the other minor methods, techniques and practices fall under the realm of permaculture when practiced wisely. Permaculture includes all that meet the standards of the three ethics. At least that was my take on it.
