You are very welcome to use anything on this site for your own enjoyment or to design or improve your own permaculture system. You are also welcome to share it (with credit) and include it in any course that is provided free of charge or any publication that is distributed free of charge.
If you wish to include my material in a paid course, or any kind of publication that generates a profit, please contact me about permission and payment. I am happy to negotiate either a donation to an aligned charity, a one-off fee, a licence fee or some form of ‘in kind’ payment or to just let you use my stuff for free, but I think we can all agree that the choice should be mine. Please don’t profit from my work without discussing it with me. That would be inconsistent with the permaculture ethics of fair share and people care.
I am the legal owner of all content on this site apart from that content which is credited to others, or linked. I never intentionally use someone else’s work without credit. Permaculture is a vast body of knowledge and it is possible that, from time to time, I unintentionally recycle someone else’s ideas. If you think I should credit you with something please let me know.
