 The Yaeda Valley, long uninhabited due to the tsetse fly, is now occupied by Datooga herders; the Datooga are clearing the Hadza lands on either side of the now fully settled valley for pasture for their goats and cattle.They hunt out the game, and the clearing destroys the berries, tubers, and honey that the Hadza rely on, and watering holes for their cattle cause the shallow watering holes the Hadza rely on to dry up.Most Hadzabe are no longer able to sustain themselves in the bush without supplementary food such as ugali.
