To support yourself off the natural materials at hand for a year, you would have to cover a lot of area, even if you were by yourself. Hunter-foragers of the past were nomadic because they had to move with the weather and available food. It would be very hard these days. Traveling by itself is labor- and strangth-intensive, not to mention the time.
It seems to me that it would be far easier if you could find some decent soil and had some seeds, to stay in one place. It certainly would take less land.
