Part 3 · Subsistence First
What a Subsistence System Is
A subsistence system grows the household's calories, protein, fat and micronutrients from its own land, with a store for the bad year. A vegetable garden is not one.
Most permaculture courses end at the vegetable bed. The bed is real work and real food, but it answers a smaller question than the one a household actually faces. The bed feeds you in August. Subsistence asks whether you eat in February, and in the year the harvest fails, from your own ground instead of from the shop.
A subsistence system is a system that produces the household's calories, its protein, its fat and its micronutrients from its own land, with labour and inputs it can sustain year after year, and with a store that carries it through a bad year. Everything the system does not grow is a supplement. That definition is stricter than the way the word is usually used, and this part of the course is built on it.
The two loops
A farm runs on two loops at once, and the difference between a subsistence farm and a hobby farm is which loop carries the weight.
The first loop is internal: land feeds soil, soil feeds crops, crops and animals feed labour, labour feeds processing and preservation, the processed food feeds the household, and the household's energy feeds the labour again. When this loop turns, the farm makes its own fertility and its own hands.
The second loop is external: purchased inputs make production possible, production makes you depend on the seller, and the dependence is the vulnerability. A farm that runs on this loop looks productive and is fragile. Subsistence is the degree to which the first loop closes and the second loop stays short.
Neither loop is ever fully closed. The core research question of the subsistence curriculum on file in the vault is exactly this: how a household obtains its food, nutrition and resilience from a limited land base while minimising dependence on external inputs. Minimising, not eliminating.
What counts, and what does not
Vegetables are micronutrients and appetite. Grain, legume and oil are calories. In Alik Pelman's design, the three rainfed staples supply about 85 percent of the calories in the diet, and the irrigated garden supplies the rest of the nutrition. A homestead of raised beds with no staple block is a supplement to a food system, not a food system, no matter how abundant it looks in high summer.
This is the first idea that separates a subsistence course from a gardening course. The crop that fills the store and carries the winter is dull, a field crop that takes most of the ground. The crop that thrills the table is a side dish in the arithmetic.
The proof of concept
The claim that a household can actually do this is not a wish. Alik Pelman, a philosopher at the Technion in Haifa, bought a 0.2 hectare plot in the western Galilee in Israel and has lived in nutritional self-sufficiency on it since May 2013. The cultivated area is 740 square metres according to the peer-reviewed paper, and he says 750 square metres in his own videos. The farm produces a complete diet for one adult: about 2,000 kilocalories a day with all recommended nutrient intakes met except calcium, which reaches about 80 percent.
State plainly where those numbers come from. The land area, yields, labour and nutrient adequacy are published in two 2024 peer-reviewed papers, but the papers are a single case study written by Pelman and his co-authors about Pelman's own farm. They are strong evidence and they are self-reported. The figures he gives in interviews after 2024, the cost of wheat, the area of vegetables per person, the offsetting costs of seed and compost, are his own account and have not been independently verified. Treat both as his numbers, and say so when you repeat them.
Subsistence is not withdrawal
There is a version of this argument that says the answer is to leave the economy. Pelman's own 2026 paper with Ohad Nachtomy refuses that version. It argues for self-sufficiency as a political virtue, defined as "domain-sensitive reduction of market reliance," and it says the position is "universalizable without requiring social withdrawal or technological regression." He concedes the benefits of industrial society. So cite him for the diagnosis, that heavy reliance on distant production carries social and ecological complicity, and do not cite him as a case for dropping out.
Loop Farmstead's own position, stated once: subsistence first, then a fair price for surplus. Markets and trade are fine. What is not fine is a farm that cannot feed the people on it.
Exercise
Your household's subsistence baseline
List every person who eats from your kitchen, with age and weight. Write each person's daily calorie need (start at 2,000 for an adult, less for children). Multiply by 365 to get the annual calories the household needs, then add 20 percent for waste, storage loss and a bad year. Write the total on one line at the top of a page. Every lesson in Part 3 adds to this page.
Exercise
Name where every number came from
Take the baseline you just wrote. Next to each figure, write its source in one of three words: measured, published, or assumed. If a number came from nobody but you, mark it assumed and treat it as a placeholder you will replace with a real measurement. A subsistence plan is only as honest as its worst-sourced number.
Fieldwork
Walk the ground and name the blocks
Walk your ground with a tape measure and a notebook. Sketch the whole parcel. Mark where the house is, where water arrives or collects, where the sun lands, and where the ground is flattest. Do not plan yet. You are finding where a staple block could sit on rain alone, and where a garden could sit near the house and the water.
Failure mode
The garden-only trap. A property full of beds, fruit and salad that grows no calorie crop is a garnish for a supermarket. It will look abundant every August and empty every February, and the first real supply interruption will show the difference between a farm and a food decoration.
