The standard-sized allotment (ie. 30 feet by 90 feet) was supposed to be able to keep a family of four in vegetables for at least three-quarters of the year.
I suppose there is an issue of calories here. If we wanted to eat potatoes all year we could provide most of our calorific needs but it wouldn't be a very exciting diet?I'm also thinking about crops which crow well on allotments but don't transport very well (in supermarket lorries). These cash-crops would be beneficial to be grown in urban areas as you would get more money for them if you sold them locally.
