In the past years, half-nomadic tribes, like the Massai, Wasukuma and Wamangati, have immigrated in growing numbers from northern Tanzania. These tribes live on cattle breeding and therefore own big herds of cattle.
Katika miaka iliyopita, makabila yenye asili ya ufugaji wa kuhamahama kama Wamasai, Wasukuma na Wamang’ati wamehama kwa ongezeko kubwa kutoka kaskazini mwa Tanzania. Makabila haya hutegemea sana ufugaji na hivyo humiliki kiasi kikubwa cha mifugo.
