Permaculture is, among else, a design method. But would it have been enough if Bill Mollison stayed in the bush growing his own food and letting the world go further in the toxic way, without showing what he is doing? Wouldn't we be happy to know how even our grandfathers and grandmothers gardened?
There is a network who documents sustainableland management technologies all around the world. It consists of diverse groups, persons, universities, ... and everything is available for free to anyone with an internet connexion.
You can do a restricted search matching your conditions (climatic, cultivation...) and see what is done and you could do. If you register, you can document your own technologies or the ones of friends. This is the link to it.
I would love to see some questionnaires about swales, as it helps to spread it. It is also helpful because the costs and the time needed are in the summary, so if someone needs more than just a general idea to convince someone it could be available. In the network, they are helpful (but sometimes slooooowww) if you need help to document something. The questionnaire helped me, (and the people I interviewed) to understand better how the technologies work.
