Whether permaculture is anthropocentric depends vastly on the individual person practicing it, his/her belief system, his/her influences, and probably the overall time permaculture is practiced.
The longer I do permaculture, the more I let the ecosystem make decisions, and the more I withdraw from the responsibility of influencing cultivation. After all, it is the plants, the fungi, the insects and worms who do most of the work, not me. They instinctively know what to do, I don’t. I have to learn all of that.
My main job is to assist the ecosystem during its recovery, increase soil fertility, reintroduce native species and “friendly” plants like keystone species trees that prepare the land for yet others to come; and from there on I let the gods (or whomever else) decide. Seeds often come with the soil (or in bird shit), so when a particular plant grows in a particular place, I’m like “Alright, if this is where you want to grow…”. Maybe I didn’t intend for this plant to grow in this place, but if it clearly wants to grow there I accept that and help it where I can. There’s few places in my garden where only a handful of individuals of the same species were purposely planted close together, because if you go to the jungle (the ultimate functional and self-sustaining ecosystem) the plants there grow wildly mixed, and it works perfectly without composting systems, planting, mulching, weeding or tilling.
To me, permaculture is healing of the land and healing of the (human) spirit; Masanobu Fukuoka said that “the healing of the land and the purification of the human spirit is the same process”. The longer I do permaculture, the more I realize that there are much bigger things at work, and it is best to go with the flow, to follow the Tao.
Anthropocentric permaculture is practiced by those who not yet or still don’t understand how Nature works. If you keep an open mind and listen to your ecosystem, it becomes obvious that the goal of Nature (and therefore the goal of permaculture, which is a form of cooperation between humans and the rest of the ecosystem) is wilderness - and we humans learn along the way of practicing permaculture what our place in that ecosystem is: what plants and animals we should eat and how much of them in any given season, what the limits and boundaries are, etc.
If I can’t grow tomatoes in the tropics, well, I eat something else. There is no point in building plastic greenhouses to artificially help a species survive that doesn’t want to grow in this environment.
When the plants get weaker at the end of dry season, I eat more insects (who are abundant) and fish (the water level drops so they are easier to catch).
In my opinion, permaculture automatically renders itself meaningless after the ecosystem recovered and you have helped create an ecosystem that sustains itself and allows to hunt and gather for food, much as the Taoist teaching of yin and yang is merely a guideline for times of imbalance and should only be followed until ‘humans and beasts live together in harmony’ again. After all, in the beginning, when humans still were humans and the ecosystem was still in balance, there was no need for the differentiation between yin and yang (and no need for permaculture).
All in all, I do not think that permaculture is fundamentally anthropocentric. From my heart I would say that anyone practicing permaculture with an anthropocentric mind is simply not fully there yet and maybe needs to open his/her ears and eyes to what the land itself wants.
