Self-Sufficiency Acreage Requirement?
If you look at Buffalo Bird Woman's Garden: http://digital.library.upenn.edu/wom...en/garden.html You can see what they did for subsistence living in North America 150 years ago. Corn & squash for carbohydrates, beans for protein, sunflowers for fats, ground cherries for vitamins. (She mentions buffalo scrotums & deer antlers as tools, but I don't recall if she says how much meat they needed by hunting.) Jeavons books aim at something like what you are interested in: http://www.bountifulgardens.org/grow...e-books.html#1 I don't know if anyone ever actually lived exclusively on the produce they grew in these little plots. Looks pretty hard to me. Hope this helps, -- Bob Mounger gregpresley wrote: Although people have talked about the work, the land, the crops, and maybe the animals, you really have to think about your caloric needs, and what is practical/possible to grow to supply those. Vegetables are great, (my favorites), but most are low in calories, so they won't supply the energy you need to do the farming. For that you need concentrated sources of carbohydrates. A large quantity of potatoes can be grown on small plots, which is how the Irish survived when most of their most farmable land was owned by the English. When potatoes are your SOLE source of carbohydrates, you are probably talking something like 5 pounds per day....Grains like wheat need a fair amount of land to grow, as only a tiny part of the plant translates into useable food. Most cereal grains, like wheat,corn and oats, need more land, but less intensive cultivation, except at planting and harvest time. (In biblical times, didn't they just scratch the ground and then throw the seed on the field out of bags or something?) Some of the small grains eaten whole, such as quinoa and amaranth, could probably be grown on a much smaller plot and could provide a good carbohydrate alternative to potatoes - as well as adding some needed variety - but only if you like their taste. I think buckwheat can also be grown compactly, as it is not a true grain. Root vegetables such as turnips, parsnips, and rutabagas are also pretty good sources of carbohydrates - and carrots too, if eaten in quantity. Hard winter squash is also a pretty good source of carbohydrates. That might need more land if you are going to plant enough to last through the winter. With a total vegetarian diet, you will also need to think about sources of fat. It would be a good idea to plant a nut tree - however, it might be 15-25 years before you get an impressive crop. Beans, dried peas, and other legumes can supply the majority of protein needs, but again, you have to like them - and you have to have a successful crop. Most people would want to have eggs for an additional protein source, but keeping chickens adds another layer of work to a one-person operation. If you wanted milk, then you are talking about cows and/or goats, which again, add another layer of work - and more land requirements - as well as setting aside some land solely for grazing. In some cultures, certain types of insects are eaten as sources of protein - for example, termites. But that might be hard for a person from Western Cultures to stomach. "Down Under On The Bucket Farm" wrote in message ... Hi Everybody, I am working on long-term plans for self-sufficiency, oriented to buying some bare land and building an off-grid house, rainwater catchment, composting toilet, etc, etc. One issue is the question of how much physical space would be needed to grow enough food to completely support myself? I am willing to eat anything that is healthy, preferably remaining vegetarian (although I am quite willing to have chickens for eggs, and perhaps a goat for milk.) This would involve one person living alone, in decent physical condition, willing to do hard work and learn whatever is needed. I realise that the yearly food yield will have to be spread out via preserving, canning, etc. My "day job" can be done remotely, via wireless Internet connection, with flexible hours, thus leaving time and opportunity for extensive gardening/farming, etc. I do understand the risk of, for example, having a bad year, bad weather, etc, and so would have money set aside to buy food in that case. But the plan is to avoid that if at all possible. I live in New Zealand, with plenty of rain in winter, but also reasonable sunshine in summer. So... How many acres of flat, farm-able land will I need? Thanks in advance! -V. -- Guide To DIY Living http://www.self-reliance.co.nz (Work in progress) |
