We have that little land. The location is simply more important. You must have an income stream. I think it is difficult living from the land in financial terms. I recently talked to a very small farmer. They work off site. Selling any produce, meat or
milk boils down to government regulation and transport costs. He told me that his neighbours if they do not work outside make money with luxury, like breeding special dogs, race horses etc. This has nothing to do with a
permaculture lifestyle working for the upper 5% of the society, but this is recession proof.
If you have little land look what surrounds that land. Is it subdivisions with suburban houses? Then I would not take it. If there is open best wild land around I would go for it. If your neighbour sprays on a small block of land your whole block will be sprayed too.
Our land is soil wise very very bad. We are still developing it. At the moment we have all our veggies and the
trees are still small but we will have all our fruit. I am developing the site bit by bit and that means we will have a part of our staples too. We have all our eggs too.
You can keep even sheep and goats there, but there is very much work involved as the food has to be brought from outside. And as the area is too small you will have to take them for a walk.
