You can do permaculture programs at local colleges and universities as well as at horticultural centers. It's a huge topic and I just use it in my garden but, it gets into designing houses and even sustainable urban development.
There's a catch phrase in there: "sustainable development" that gets thrown around by government a lot but, if you look into the permaculture basis of sustainable development, it really has some positive aphorisms.
But, seeing as this is a gardening site: I'll stick to gardening.... check out your local library as well. Lot's of info there, I think I told you this already but, the bible for permaculture gardening (in my opinion) would have to be Gaia's Garden by Toby Hemenway. Definately worth a read, I read it from one of my University's smaller librairies and then bought it. I always see it on tables at local organic and heirloom gardening and plant symposia. So, see if you library has it, I think that if you look at other books they will be more theory related rather than practical uses of permaculture in the garden
And if anyone else knows of any other good books of websites on the topc please share them with us!
Thanks a million for starting this thread Lorax, I personally love having you here at the HG!
Incidentally, if anyone uses facebook: there is a permaculture group in there.
