true, i understand your point, its awkward if somebody is telling an old experienced gardener that mulching really is better while that older guy might have never experienced any advantages, just disadvantages (slags and snails?), and the somebody only has one growing season behind him. awkward even when this somebody can back up his point because his teachers really did perfect the art...
but the problem is that the intimate relation that some people formed with their land is based on that land. things that work there, can not work somewhere else, and the other way around. they way i understand it, the goal of a permaculture course should be to teach the abilities for people to learn themselves about their land, and how to form that intimate relationship. its the way of listening to your land, the way of working with nature. the mind-set if u will, that can be taught to people, not the way how to.
(well to some extend you can learn 'how to' -knowledge that is quite universal, like how to make
compost. what elements are necisary in a guild etc. but the basic knowledge and understanding of plantlife (for example) has to be learnt by people themselves. you learn this by experience, and preferably in the long term, forming a relation with that land, if you have land.)
When owning a piece of land, why not give educational purposes to it, without pretending to know it all. you can also teach without pretention. teaching is maybe a big word then, sharing knowledge or experience can also be done as you go cant it? Im involved in a project that promotes natural and organic ways of gardening in a city, learning about permaculture for us means a discovery quest, which, as we go and develop, we share with our surroundings, in a non-pretentional way, explaining:
"here we are trying out different ways of fertilizing, mulching, composting, liquid-nettle-comfreyfeed (whats the english word?) etc." and sum up the advantages etc we allready know of.
The problem here, i dont know how it is elsewhere, is that there simply aint enough pc-teacher, left alone pc teachers with a lifetime of experience. And i think it would build up to slow to meet demand, if everybody needed to perfect themselves, and their ways, before being able to teach or share...
Second thing i question (a bit, in a superfriendly way) is the notion (that follows from the point that you made) that you can only 'do permaculture' if you own land, or at least a garden, and that it neccisarily involves growing stuff yourselves... which i dont think to be true.... i think the permaculture designmethods can be used for designing gardens and land, but also a house or the way you live your life, an organisational structure, etc...
or dont you agree?
