Coban, I understand your concerns. One thing to remember. though, is that in most
permaculture books and designs that I have seen, a food forest is only a part of the total design, usually in the areas a bit farther from a house, with beds for annual and perennial veggies, herbs, edible flowers, and small fruits, things that are used frequently or need more care and attention, closer to the center of the design. Many pc designs also include space for some grains and/or main crops, such as potatoes, large plantings of food to freeze. bottle, or store in root cellars, etc.
Bill Mollison, the father of
permaculture, in the books I have read, never indicated that we
should eliminate annual crops, but that we should aim to use zones for correct placement of plants and other elements in our system according to how much care they need or how often we use them. A food forest was simply a part of that system, as an alternative to a conventional monocrop orchard that required a lot of labor to maintain it. By incorporating guilds of plants which support the main crop
trees, we reduce our labor and receive more yield while creating habitat for the birds and beneficial insects that are an essential part of a healthy forest.
Another point to consider is that it is possible to make "breads" and other baked goods from non-grain flours such as coconut, almond, chestnut, etc, as many people who share my gluten-intolerance have been learning, with the growing numbers of gluten-intolerant people increasing dramatically in recent years.
Yes, I think most of us try to grow as many kinds of perennial plants as possible, given limitations of hardiness and climate etc, but for the majority of folks,especially in non-tropical areas, beds of annual crops still seem to have a role in helping us meet our individual goals of being more self- or community-reliant in whatever foods we are able to supply by our own efforts or locally (meaning grown within 50 or 100 miles, wherever possible). Whether that is simply fresh herbs to add to a purchased salad, or fresh berries from a neighboring berry farm, or a few beds of salad greens and veggies for stir-fry, or buying food from a
local food co-op or farmers market, it still reduces our dependence on big ag.
I do tend to aim toward having my
yard be mostly a food forest, but it does take years for tiny shrubs and trees to start producing fruits and nuts, etc. In the meantime, my yard does supply me with green onions and other herbs, greens for smoothies, and a green oasis to observe flying, twittering birds and beneficial insects which inhabit the young trees and shrubs. I just harvested a bucketful of sunchokes that I have been using in stir-fries, with
mushrooms, onions, and eggs from my small flock of hens. The sunchokes also made a very nice privacy screen between my back yard and the alley last summer, and the dead stalks are great to add to the
compost pile or just chop n drop.
I don't use dairy products, and didn't use eggs or meat or any cooked food for 10 years, but with my own really fresh, home-grown eggs, from
chickens who are free to scratch and eat bugs, weeds, and greens from my unsprayed garden, eggs have become part of my life again. I do still buy grain for the hens, and we buy bags of rice and other grains to supplement whatever food we can grow, but I don't buy any commercial feed. I recently learned about a method for sprouting the grains for the
chickens, and have started doing that now, at least until the weeds and grasses start growing so the hens can go back on pasture.
I don't know if I ever will be able to supply all my food at home, but I don't think that is really essential. I hope someday I can develop a demonstration garden that might inspire a few others, so we can develop a community of people with different products available, but for now, I just do the best I can to grow what I can. Being in a cold-winter climate with a short growing season, it is not possible to provide all my food, year round, unless I invest in a huge
greenhouse, but whatever I can grow is a real
boost to my budget and my health.
I have read about a community in Spain that I believe is practicing vegan
permaculture, I assume they are probably growing lots of fruit and nut trees, not sure what else. I have also read about others in the UK (Scotland, maybe) that were using chestnuts and hazels as their main source of calories. It might be possible, with a bit of research, to find more about such groups and alternatives to annual crops. But as I said in the beginning, it does take years for most of these to start producing a crop.
Please don't limit your ideas to 'only' a food forest, but look at all the
permaculture tools (hugelbeets, square foot gardens, sheet-mulched garden beds, keyhole beds, sunken greenhouses, and all the other ideas discussed here on permies and in the permaculture literature and videos). Based on my understanding of the PC toolbox, what we are after is an integrated system that uses many tools, according to which ones seem to fit our circumstances, in order to achieve whatever goals and desired outcomes each pc practitioner visualizes, to create an abundant life, while living within a
sustainable or regenerative environment.
