Self-sufficiency




Self-sufficiency is usually applied to varieties of Sustainable Living in which nothing is consumed outside of what is produced by the self-sufficient individuals. Examples of attempts at self-sufficiency in North America include Voluntary Simplicity , Luddism , Homesteading , Survivalism , and the Back To The Land movement.

Practices that enable or aid self-sufficiency include Autonomous Building , Permaculture , Sustainable Agriculture , and Renewable Energy .

The existence of an effectively closed system makes self-sufficiency a necessity for any form of Space Colonization . An extreme experimental example of self-sufficiency could therefore be said to be the Biosphere 2 project.

The term is also applied to more limited forms of self-sufficiency, for example growing one's own food or becoming economically independent of state Subsidies or (in the case of larger political entities) Foreign Aid .
