Basically, a bioregion is defined as a geographical area that forms a natural unit in terms of natural features, such as landforms, soils, climate, flora and fauna and water catchment area. In addition, a bioregion is also through interconnected and related social Systems, traditions and local customs marked.

​

Alan van Newkirk described a bioregion as a habitat in which all life, i.e. people, plants and animals, form a community that ensures survival, that is, living together in sustainable cycles and cooperation and respecting one another.

​

The term bioregion also describes a regional, sustainable economic system within which people work with regionally and organically grown, renewable raw materials. Regional, cooperation-based trading and sales structures are of particular importance.
