a person can have a small patio or kitchen garden.
if they own land people can plant fruit and nut trees and have free food for years.
When I was a kid in the fiftys, we rented a house with two apple, two pear, a sweet cherry, and sour cherry trees and what seemed like a gigantic blackberry patch. Heaven for a 5 year old. Of course there was an outdoor toilet and baths in a galvanized tub.
