2.600 Komo Ganza live in the forested plains of the Blue Nile Province of Sudan. They also live in South Sudan and in Ethiopia.
The Komo Ganza are shepherds and farmers. They raise cattle, sheep, and goats. Their crops include sorghum, maize, sesame, okra, peppers, cotton, and tobacco. They engage in some hunting and fishing, and also do some trading with other nearby peoples. The men hunt, fish, and do most of the herding and milking, while the women help the men with farm labour. The women also collect honey from the hives in the bush.
Komo Ganza marriages take place by the exchange of sisters from one village to the next. Marriage between close relatives is forbidden. The groom is not required to perform a bride-service (working for the bride's family before a marriage can take place), and a bride-price is uncommon. Polygamy (having more than one spouse) exists, but only a few of the wealthiest Komo Ganza have more than one wife.
Each village (or small group of villages) has a headman who inherits his office and exercises limited authority. He is considered "the Father of the Land." Although families clear and cultivate the fields, individual families do not own the land. Instead, the land collectively belongs to the entire village, under the leadership of the headman. The headman also keeps in his possession the symbolic insignia of the Komo Ganza, such as strings of beads, spears, and village drums.
"Rain-makers" (men who conduct rituals in order to bring much needed rain) also inherit their positions and may sometimes serve as village headmen. In addition, each village has a religious expert who specializes in magic and is subject to inspiration from spirits.
Most Komo Ganza follow their traditional ethnic religion. This religion teaches the worship of a supreme god who is considered the creator of all things, and the worship of the spirits of dead ancestors. Divination (the use of supernatural powers), magic, and rain-making are also a part of the traditional religion.
