Dumo culture
Agriculture
Sago is the main staple food, where the clan owns individual palms. Within the clan trees are allocated to individual families, if it was planted by an ancestor. Sago takes an average of 40 years to grow so a man plants the sago for his grandchildren. A man's status is measured by the number of plants he plants for his descendants. Food gardens are a joint responsibility where men clear the larger trees, and women clear the undergrowth. Although decision making was supposedly made by the men, the women had covert decision-making power behind the scenes over many gardening decisions. Most of the planting is mostly done by the women, who collect seeds from other women, although men too can collect and plant a garden. Traditionally pigs were raised by the women although traditionally owned by the men.Economy
The Dumo culture has its own currency called the Deh and Hu-o. The Deh has the form of green jade beads stored on a string, in which they have an base 8 counting system for payments. One could give one Deh to someone who provides a fish or sago meal. If my brother gives a lot of fish, and I get a basket of sago too, I would recompense with 8 Deh. There is a lot of superstition about how the Deh came about. For example, there is a legend that Deh fell as seeds from a tree that fell into Lake Sentani, in West Papua, and changed into Jade Beads. There are also other legends about how they came about. The most recent findings is that they were made in Asia, somewhere in Borneo, Brunei, Pakistan, or India. They are not just normal beads, local people are very discriminating as to which are the genuine article. Different types of Deh have different prices – so that green ones have a value of about 5 Kina, the blue have greater value. The light blue are very rare, dark blue is the most expensive. Brown, white, and transparent, varieties have intermediate value. The dark blue Deh has a value of about 20 Kina.Ho-u is made of the same Green Jade, some are white or brown, or clear glass. It currently has a value of about 500K for one. Each Hu-o is circular with a diameter of about and they are about ½ an inch thick, with a central hole about 3-4 centimetres in diameter.
Hu-o are used usually for brideprice and death ceremonies. For example, when some member of a clan dies. A woman and her male sons are the property of her brothers and the clan. At her death the Hu-o goes to her immediate clan brother, and 24 Deh are paid to other male clan members. To attend a celebratory feast, a woman must pay 24 Deh plus a minimum of 100 Kina, to the brothers and other male Clan members who have organized the feast.
The Deh and Hu-o are believed to have come from somewhere in the west. They came with migration. Women wear a belt with beads set in a distinctive pattern that tells members where they come from, for example a Papua New Guinea woman may wear beads that inform others that she came from Skuo, just across the West Papuan Border. The Deh of poorer quality are used for decoration, where the pattern of decoration tells others which clan you are from.
