It'd still be interesting to know how small a community (in how much land) could realistically be self sufficient.

With my peak oil hat on, I'd say that that could even be a vital question,

I think it's a fair question, I've been asked and have wondered myself what land resource is required for self sufficiency, but as Judith says I think it's an awful long time since humans lived in self sufficient family groups on a large scale.

If the question is changed slightly to how much land would a family of 4 need to be 95% efficient and the 5% is essentials such as medicines that cannot be grown or made. That gives us a bit of room to think. If we also use the peak oil example and think of, say, 50 years time then we may have to produce enough for all our needs.

So, using some info from my 'Small Woods' info pack from the Small Woods Association, it suggests you need about 3 hectares of woodland to heat a 4 bedroom house all year. That's a little over 7 acres and I think if you allow for a smaller house and cooking then 10 acres of quality woodland is required.

If you have this sort of land I expect you to be able to gather some food from it. Coppice cut on a 10 year cycle would have a couple of acres each year that could produce some crops. There would also be meat in the form of vermin you have to control (rabbit and pigeon mainly) and possibly food from the trees from leaves and fruit, although coppice may not produce much fruit.

I've always had the idea of about 50 acres in my mind for a smallholding. Large amounts of woodland even if it's just very wide hedges with trees in for firewood. I would feel comfortable of being able to live off the land with a small family if I had to.

That sounds rather a lot, treac. I heard somewhere (I think it was Monty Don) that you can keep yourself in heating if you have 1 acre of coppiced ash trees. Having said that, it got to be very variable, as in how many rooms you're heating, and how much heat you want - Are you out with your oxen ploughing fields all day, and only want a couple of hours in the evening!? - or on insulation etc etc etc.

I guess we go through a half shedful (6 x 10) a year, but the fire isn't our only heating, and is only alight about 50 percent of the time, Ocotber to March. We don't cook on it either....., but even if you allow say, 5 times that, I reckon we're only talking in numbers of a handful of trees still, I know there are differnet stages of copppice, and not all be be mature at once, but it still seems like an acre or two would do it.

Mind you, I have absolutely no aspirations to be self-sufficient, although I would like one day to be able to produce all of my meat, and the majority of its food, and my veg. Not this year, though

I think that 50 years is rather optimistic,

Or, more sensibly, back in the middle ages, how much land did you have (as a serf),

It is quite amazing what the middle ages serf did not have. Most of our staple fruits and vegetables are of recent origin, either from breeding or from crossing with American species. That's why the peasants mainly lived off bread and beer. The large number of modern species and varieties, not to mention greenhouses and cloches, makes us less dependent of agriculture now than ever before.

Of course, our hypothetical family would still need to buy greenhouses.

And on another thought, how do you make a polytunnel without oil?

But what did they have!? A few acres for wheat and barley? Some more for their oxen?
