Introduction / History

The Wanuma Usan in PNG are an indigenous people living in the Madang Province, particularly along the southern slopes of the Adelbert Range. Their communities are typically found in remote inland areas, where rugged terrain has helped preserve their distinct language and identity over many generations.

They are part of the wider grouping of Papuan-speaking peoples in northern Papua New Guinea, a region known for its extraordinary linguistic diversity. The Usan language, also known as Wanuma, belongs to a branch of the Trans–New Guinea language family, linking them to other inland groups with related linguistic roots.

Historically, the Wanuma Usan have lived in relatively small, self-contained communities, with their history and traditions passed down through oral teaching. Contact with the outside world increased through mission efforts and government presence, bringing both change and new opportunities while many traditional patterns remain.


What Are Their Lives Like?

Daily life for the Wanuma Usan is closely tied to the land and forested environment. Gardening is central to survival, with root crops and other locally grown foods forming the basis of their diet. Hunting and gathering also contribute to daily sustenance.

Villages are typically organized around extended family groups, with strong kinship ties shaping leadership, cooperation, and social structure. Respect for elders and shared responsibility within the community are important values.

Homes are built using local materials and are adapted to the mountainous environment. Travel between villages is often by foot along established paths.

The Usan language remains central to identity and daily communication, while Tok Pisin may be used for interaction beyond the immediate community. Oral traditions, storytelling, and the passing down of knowledge continue to play an important role in preserving their heritage.


What Are Their Beliefs?

The Wanuma Usan are identified primarily with Christianity, and churches are present within their communities. Many would describe themselves as followers of Jesus Christ, and Christian teaching has had a meaningful influence on daily life. At the same time, traditional beliefs may still be present in the background, particularly in how certain individuals understand spiritual matters or the causes of illness and misfortune. These perspectives may exist alongside Christian faith in varying degrees. The New Testament has been translated into the Usan language, providing an important resource for personal faith, teaching, and church life.


What Are Their Needs?

There is a continuing need for deeper spiritual growth among the Wanuma Usan, especially in developing a clear and grounded understanding of Scripture. While Christianity is present, strong discipleship is essential so that faith is firmly rooted in God's word.

Church leaders would benefit from encouragement and sound biblical training so they can faithfully teach and guide their communities. Strengthening families in their understanding of Scripture is also important for passing the faith to the next generation.

Access to scripture in forms that are widely used and clearly understood remains important for continued growth.

Like many remote communities, they also face practical challenges related to education, access to resources, and maintaining their language and identity in a changing world.


Prayer Items

Pray that the Wanuma Usan would grow in a deep and faithful relationship with Jesus Christ, grounded in the truth of scripture.
Pray for church leaders to be strengthened, equipped, and committed to teaching God's Word clearly.
Pray that the New Testament in their language would be widely read, understood, and lived out.
