This one is a challenge ;) I started writing a response and promptly got lost in the weeds ;) 'cuz Permaculture is like that. In my opinion it has to begin with the ethics or it isn't Permaculture. The ethics aren't a huge amount of theory, they're the practical decision making tools applied at every decision point. I think it's probably important to tell people there are not any techniques that define permaculture, i.e. you don't have to do swales or have an herb spiral.
Permaculture is a whole system approach. It teaches us to see everything in relation and connection to everything else. It is probably worth emphasizing this by beginning with
water management. Water management is both fundamental to the success of everything you might wish to do on a site and one of the first systems you need to put in place on a site. Arguably The first system, but we're generally not dealing with blank slates... Anyway - Water management as a key element to their entire
project and as a teaching tool showing the interconnections and relationships of the system's elements. BTW, this takes one all the way down to the Mollison classic analysis of a
chicken. It also leads into Zones, because Zones aren't geography, zones are system workflow diagrams. And that leads into function stacking, because Zones, going from one out to five, are areas of decreasing intensity of function stacking of your labor. Zone 1 is highly labor intensive and each action ought to have multiple purposes, but when you get out to zone 5, your labor is nearly zero and of very limited impact.
Holmgren's twelve principles are probably the most concise guide to teaching Permaculture that I'm aware of, but I get that they're not all obviously "practical". One of them is practical
enough, at many levels, that it ought to be early on in any "practical" permaculture teaching - Use small, slow solutions. Why is it important? Because people get totally overwhelmed by how much they have to do and throw up their hands in despair. And it's entirely understandable. We're asking them to make a paradigm shift. To see their world from a new perspective that changes how they see - well, everything. So here's a really important concept - You Don't need to do it all at once. You ought not to do it all at once ;)
At the end of the day, if what the
class is really after is growing lots of food asap and not changing their entire lives (because whether you thought it was going to or not, learning permaculture chnges your entire life), then I suggest teaching them French Intensive Gardening and leave Permaculture for the ones that come back next year and ask "What more can I do?"
If I'm going to do a design for someone, whatever their knowledge level about any aspect of the process, after a really brief elevator speech style intro to Permaculture, I'm going to begin with asking them what it is they want from the project. As we work our way through what they want, I'll ask lots of leading questions - you said you want to grow your own food; what do you like to eat? Are you willing to take on the responsibilities of having livestock? I can't design with them if I don't know what their goals are, and they probably don't actually know what they are themselves. They may say "We want to grow all of our own food" But they're living in a cold temperate area and cannot live without their citrus - and that's just not going to grow where they live ;) As we go through the process there will be natural opportunities to explain why Permaculture suggests this solution to that issue and I'll try to give responses that don't leave them with their eyes glazing over ;) If you can get it 'right', the way you present the choices leads the client to ask for the reasoning and you can educate them about the permaculture design process in that way.
Thank you, Kate, for bringing this subject up. You've made me think about teaching and all that entails and I've been away from all of that focused on building our own homestead and permaculture design. It's fun to re-visit this facet and recognize ways in which my thinking about it has changed, or not, with our experiences on our own design.
