A community that cooperates and harnesses its resources together is said to be practising

Communalism is a traditional system of social organisation in which members of a community cooperate, pool their resources, and work together for the common good of the group. Under communalism, land and other productive resources are often held collectively, and the fruits of communal labour are shared among community members.

This system was widely practised in pre-colonial African societies, where the extended family or village community worked together on farming, building, and other tasks. The emphasis is on collective ownership, mutual aid, and shared responsibility rather than individual accumulation of wealth.

The other options describe different economic or political ideologies:

• Capitalism is an economic system based on private ownership of the means of production, individual profit, and market competition.
• Communism is a political ideology advocating classless society where the state owns all means of production, as theorised by Karl Marx.
• Socialism is a system where the state or community controls major means of production, aiming to reduce inequality, but allows some private property.

The distinguishing feature of communalism is its voluntary, community-level cooperation without state control - unlike communism or socialism, which operate at the national or state level.
