There 7.68 billion acres of arable land. if everyone did this and lived one one tenth of an acre then that’s room for 76 billion people just on the arable land where there is actually 36 billion acres of land on the planet.
If farming were turned into vertical farming building with ten floors a piece at 1/10th and acre per level that’s 760 billion. At 100 floors that’d be 7.6 trillion. I would need to review an Isaac Arthur video about the maximum occupancy of the planet, there may be heat problems with trillions of people on the planet.
A tenth of an acre would be a square around 65 × 65 feet, or so.
Over 6,000 pounds of food per year, on 1/10 acre located just 15 minutes from downtown Los Angeles. The Dervaes family grows over 400 species of plants, 4,300 pounds of vegetable food, 900 chicken and 1,000 duck eggs, 25 lbs of honey, plus seasonal fruits throughout the year.
From 1/10th of an acre, four people manage to get over 90% of their daily food and the family reports earnings of $20,000 per year (AFTER they eat from what is produced). This is done without the use of the expensive & destructive synthetic chemicals associated with industrial mono-cropping, while simultaneously improving the fertility and overall condition of the land being used to grow this food on. Scaled up to an acre, that would equal $200,000 per year!
To follow the Dervaes and their Urban Homesteading activites, you can find them at.
Believe it or not, but in Soviet Union everyone were given 600m2 for free. All my relatives, friends, friends of friends, etc still preserve their 600-2000m2 where they grow vegetables, fruits, and berries. I heard that in Russia there is still 80 millions personal farms like this and that most of the food produced in the country is grown by people for themselves. You don’t have to pay any license for fishing (unless you use nets) and forests are full of mushrooms and berries.
