Subsistence refers to the means by which individuals or communities secure the basic necessities of life, such as food, water, and shelter. It often involves practices like farming, hunting, and gathering, where people rely on natural resources to meet their daily needs. Subsistence economies are typically found in rural areas where people engage in small-scale agriculture or foraging. In many cultures, subsistence living is closely tied to traditional knowledge and sustainable practices. For example, indigenous peoples often use techniques passed down through generations to manage their resources effectively. This approach helps maintain ecological balance while ensuring that communities can thrive without relying heavily on external markets.
