The Daasanach are also called Marille, especially by their neighbours, the
Turkana of Kenya. The Daasanach are traditionally
pastoralists, but in recent years have become primarily agropastoral. Having lost the majority of their lands over the past fifty years or so, primarily as a result of being excluded from their traditional Kenyan lands, including on both sides of Lake Turkana, and the '
Ilemi Triangle' of South Sudan, they have suffered a massive decrease in the numbers of cattle, goats and sheep. As a result, large numbers of them have moved to areas closer to the
Omo River, where they attempt to grow enough crops to survive. There is much disease along the river, including both
human and
animal trypanosomiasis (the
tsetse fly has increased with forest and woodland development there), however, making this solution to their economic plight difficult. Like many pastoral peoples throughout this region of Africa, the Daasanach are a highly egalitarian society, with a social system involving age sets and clan lineages, both of which involve strong reciprocal relations. ==Language==
