The Nyishi tribe practices jhum cultivation as a community, with each family participating in shifting agriculture. They are also skilled in basketry and weaving, crafts shared among the tribe. Conflict resolution is managed communally through nyelee gatherings, led by elders, to ensure social harmony. These gatherings emphasize collective responsibility and follow traditional customary laws. Their communitarian way of life fosters self-reliance and cooperation within the community, reflecting their deep-rooted tribal unity.

The Nyishi tribe residing in Arunachal Pradesh are the "people of the highlands." The Nyishi word is derived from 'nyi' equals human and 'shi' equals highland. They migrated from Yunnan Province in China, claiming descent from their mythical ancestor Abhu Thanyi. Some have converted to Christianity, while others continue to follow the indigenous religion of Donyi Poloism, with Donyi (sun) and Polo (moon) as their deities of worship. Their temples, known as Nyeder Namlo, are seen all over Nyishi territory, preserving the cultural heritage.

A communal social structure headed by elders (nyagam aabhu/nyub aabhu) who chair nyelee meetings to settle conflicts is valued in Nyishi society. Consensus-based decision-making promotes community welfare. These events take place in communal places such as the Nyele Miram and Arekh Merem. Leadership is frequently hereditary, and the society respects elders' authority, which ensures tribe unity and stability. Social cohesion is fundamental to their organization.

The Nyishi tribe's foundation value consists of a worship of nature, particularly Donyi Poloism which is careful in temple worship of Donyi (sun) as well as Polo (moon), thus forming a temple called Nyeder Namlo. They carry out oral traditions and myths with moral teachings about harmony with nature, respect for an elder, which becomes a strong cohesion of community and is connected to the land, thus making them sustainable-oriented. All through the parts mentioned above, they keep alive a vibrant tribal identity along with inter-generational continuity.

Communitarian life of the Nyishi enhances cooperation and resource sharing among members through collective farming, festivals, and rituals. These acts forge strong social bonds between members. They ensure food self-sufficiency and keep the cultural identity alive.

The communitarian traditions of the Nyishi serve to sustain their resilience in adapting to change but, more importantly, their heritage and traditional values.
