The
commons is the cultural and natural resources accessible to all members of a society, including natural materials such as air, water, and a habitable Earth. These resources are held in common even when owned privately or publicly. Commons can also be understood as natural resources that groups of people manage for individual and collective benefit. Characteristically, this involves a variety of informal norms and values employed for a governance mechanism.
Commons can also be
defined as a social practice of governing a resource not by state or market but by a community of users that self-governs the resource through institutions that it creates.
