Autarky is the characteristic of self-sufficiency, usually applied to societies, communities, states, and their economic systems.

ability to cope with a life crisis, adapt in the face of stressors, or to adjust and return to pre-crisis status

Self-sustainability and self-sufficiency are overlapping states of being in which a person, being, or system needs little or no help from, or interaction with others. Self-sufficiency entails the self being enough (to fulfill needs), and a self-sustaining entity can maintain self-sufficiency indefinitely. These states represent types of personal or collective autonomy. A self-sufficient economy is one that requires little or no trade with the outside world and is called an autarky.
