John Jeavons and others have worked out how to grow complete diets on even smaller plots of land, as small as 4000 square feet per person.
I would be worried to grow such a small number of species, personally. But it seems to have worked well for you for a long time.
Not really "permaculture" though.
How I envy Ludi's visiting 'The Farm' at Willits.
I just finished reading Carol Deppe's new book, "The Resilient Gardener", and she also talks about gardening from the standpoint of providing a total diet. She is gluten-intolerant. Her mainstay crops are potatoes, ducks, squash and pumpkins, beans, and grain corn. She talks a bit about amount of land needed, but talks a lot more about growing, varieties, processing, storing, and cooking.
Very thought-provoking read. AFter reading it once, I am going to let it percolate a bit, and read it again. I can see that with her methods and additional veggies, nuts and fruits for variety and flavor, a person could live very well. These are of course temperate zone crops, but she explains how she settled on the crops she uses, and her thinking process could be applied in different climates.
She reminds me of Steve Solomon, not so much in her methods, but in her thinking outside the box. Don't miss this one.
I'm not sure if one or two olive trees could produce enough.
Has anyone here read "A Survival Acre" by Linda Runyon? She apparently was able to live for years on wild food collected on one acre in the Adirondacks. I'm thinking of getting this book or more probably the next version "The Essential Wild Food Survival Guide."
