500 m2 in Ávila: Is it enough to eat when collapse comes?
There is a paradox in any attempt to prepare for the future: the cheaper the refuge, the harder it is to make a living there. An IT professional working in New York has just bought a renovated house in a village in Ávila, Spain, with only two inhabitants, antiestéticaturing a 500-square-meter plot surrounded by a 2.5-meter wall, at 1,150 meters altitude and 450 mm of annual rainfall. He paid 60,000 euros, including taxes and notary fees, after negotiating a discount from 80,000. He now asks what to plant. The answer is less bucolic than he expected.
How much food can you get from 500 square meters?
The first calculation in the conversation is devastating: with 50 square meters of potatoes, you can harvest nearly 150 kilos, according to an estimate circulating among participants. That is three kilos per square meter, a figure that sounds good until compared to a person's annual consumption. Potatoes yield well, but not that much.
The most repeated recommendation is to
dedicate at least a third of the land to tubers, not out of romanticism: potatoes require less vigilance than other crops and can be stored for months. The historical argument cited is the Irish famine of the 19th century, when dependence on a single variety turned into catastrophe. The lesson is not "don't plant potatoes," but "don't plant only potatoes."
Someone who warns that the garden is not the priority is a participant who knows the terrain:
with such few square meters, forget planting in the ground if you seek yield. His proposal involves fruit trees that provide shade, raised beds, pots, and scheduled irrigation. He rules out carrots due to complexity; sweet potatoes, beets, peppers, and tomatoes are viable. The mindset shift required is summarized by him: moving from consumer to producer, and accepting that things take time.
Animals: from chickens to quails
The buyer had thought of chickens. The response is that chickens are fine, but there are more efficient options:
caged quails, rabbits, and some broiler chickens appear as a complement to three or four laying hens. The reasoning is caloric efficiency: a small animal eats less and converts faster.
The problem no one fully solves is the feed. Without your own land to grow corn and wheat, animal self-sufficiency is bought at the supermarket, breaking the logic of the project. The suggested solution is having access to neighbors' plots for cereal, something not impossible in depopulated Spain but not guaranteed.
For the pantry, the conversation becomes practical:
closed one-kilogram packages instead of ten-kilogram sacks, because weevils and moths cause more damage in large sacks. And a detail that sounds like a joke but isn't: having cats. In the countryside, there are mice, and a pantry raided by rodents is a serious problem.
Water and climate: 450 mm and 1,150 meters altitude
With 450 mm annually, water is the bottleneck. The buyer has decided to build a 5,000-liter tank to collect rainwater, a figure sufficient for supplementary irrigation but not for demanding crops. The 1,150-meter altitude shortens the season and requires learning to dry, bottle, and smoke food to stretch production.
The climate warning is concrete: the province of Ávila has very varied climates, from temperate zones without frost with hot summers in the south of Gredos to areas with late frosts. Without knowing which strip the house is in, any crop recommendation is a shot in the dark. The most sensible advice given is to observe what local people grow.
The 2.5-meter wall and the fantasy of collapse
The conversation shifts to the scenario that gives the issue its title. One participant summarizes it with sarcasm:
when Mad Max arrives, it's better you have nothing in the garden because they will come with machine guns to harvest your crops. Another points out that in a real collapse, it doesn't matter what you plant, because they would raid it. The physical security of the project remains in question.
The buyer, meanwhile, insists that his goal is not speculation but moving. He works as an IT manager at a school in New York, a presencial position he cannot perform from Ávila. The village's fiber optics, however, give him an advantage others do not have. His plan is to live there within a year or a year and a half, and he admits that the global situation is getting out of hand.
The true cost of self-sufficiency
The emerging consensus is uncomfortable: 500 square meters are enough to supplement the pantry, not to sustain a person. Total self-sufficiency requires cereal, legumes, oil, salt, and feed, none of which fit within the wall. The garden reduces the supermarket bill and provides occupation; it does not replace a salary.
The buyer knows this. That is why he remains in New York while renovating the house, relying on a friend and a relative who supervise it weekly, and pays for it. The unanswered question is not what to plant. It is how he pays the mortgage, heating oil, and chicken feed when his presencial job on another continent is no longer an option.
