Bioregional

OSE Bioregional refers to the scale of an economy that is limited to its local economic bioregion. The local economic bioregion is that area which is required to provide everything needed to thrive. This includes all industrial production.

The size can vary, but is in general a 60 mile radius - that which can be traveled easily in a single day. The area can be much smaller, but 60 miles gives ample room for resilience.

This is an area of 10,000 square miles. Since there are 4 million square miles in the USA, this means there are 400 of such areas in the USA, roughly. Worldwide (57 M sq mi), there are thus about 6000 such areas.
