Do you have a mature, commercially active Permaculture operation?

The question constantly comes up in both pro-permaculture and permaculture-skeptical literature.  Finally, here's a chance to generate published scientific data on yield/land use for permaculture food producers! 

If you have a mature permaculture operation, and produce lots of food (especially for sale to the surrounding community), I'd love to talk to you about including your operation in my thesis research.  I hope to generate a case study on at least 3 solid operations.  The result will be a sustainable development MSc thesis, which will hopefully be published in a scientific journal. 

I'll happily work with producers on any continent.  If you get in touch, I can explain the methodology a little more thoroughly.  It will require significant record-keeping, but I think the benefits (global awareness, and hopefully scientific validation for permaculture and forest gardening yield sustainability) will be worth the effort!! 

Thanks, fellow permies, for your help!

Here are three operations you might want to try contacting, if you haven't already:
