Self-sufficiency refers to the ability of an individual, community, or organization to meet their own needs without relying on external assistance. This can involve producing one's own food, generating their own energy, and providing for their own basic needs without the help of outside sources. Research in the area of self-sufficiency often focuses on ways to increase autonomy and resilience, reduce reliance on centralized systems, and promote sustainability. This can involve studying practices such as homesteading, permaculture, and off-grid living, as well as exploring innovative technologies and strategies for achieving greater self-reliance.
