I would appeal to the people's good sense and reason -
permaculture is all about observing and working with natural systems to achieve maximum benefit. This is great news! Market it as such.....
So show some simple applications that people can easily employ. For example, do not talk up
compost in and of it's self.... many people have bought composters and become burned out using them. Talk compose and how one can start an easy no-fuss pile in corner of their
yard - no extra expense. I did this with my grandmother, she was the dumper mostly, except for the lawnmower boy, and I would help spread it in the spring - easy! You want faster compost - bump in an area with a few
chickens to rotate and add their contributions, also easy! No debates on the 'perfect' compose just a get out there and do-it approach.
Latest thing: It's a new craze to turn one's yard into a urban cottage farm - show 'em how to keep a small flock of birds (most cities allow at least two
chickens or ducks) and grow a few seasonal and
perennial vegetables. Talk up the benefits of not using chemicals to remove weeds and pests, but instead using a couple of lawn ducks and white vinegar.
Marketing: Use a few key phrases like -
improve your soil the natural easy way.
Solve common pest problems.
Employ a few animals to work for you!
Reuse and save big $
Make your property work for you instead of the other way around.
Etc.......
Good luck on your endeavor
