 The Batwa are generally considered to be the surviving remnants of nomadic Bushmen who inhabited Zambia long before the Bantu peoples began to arrive from the Congo basin to the north.The area is now dominated by Ila and Balundwe (or Lundwe, or Plateau Tonga) farmers and cattle herders, in at least 21 chieftaincies, who came to the area between 200 and 300 years ago.They depended on farming, fishing, cattle rearing and wildlife, often moving between a fixed settlement in the woodlands and cattle camps in the flats after the floods have receded.
