> To grow all the food for one person's needs for the whole year requires, for most people, at least 4,000 square feet—though some diet designs are possible that can use a smaller area.
> A 0.44 acre of land can produce enough vegetables and fruits to meet up with the daily calories needed for one person to feed for a year.
Food and Agriculture Organization of the United Nations, 1993:
> It is realistic to suppose that the absolute minimum of arable land to support one person is a mere 0.07 of a hectare–and this assumes a largely vegetarian diet, no land degradation or water shortages, virtually no post-harvest waste, and farmers who know precisely when and how to plant, fertilize, irrigate, etc.
> The minimum amount of agricultural land necessary for sustainable food security, with a diversified diet similar to those of North America and Western Europe (hence including meat), is 0.5 of a hectare per person. This does not allow for any land degradation such as soil erosion, and it assumes adequate water supplies.
Cut out meat and it gets better, but not that much better.
Only if you use traditional farming. Hydroponics, Aeroponics, and Aquaponics use far less resources (more startup capital but far less inputs), can grow year round (assuming indoor grows), and has 5-10x the yield per sq ft.
