Insiza District is one of the seven districts located in the Matabeleland South province of Zimbabwe. It is a rural area. Insiza District lies to the South East of Bulawayo and borders Gwanda District to the South, Zvishavane District to the east, and Umzingwane District to the West. The total distance between Insiza and Bulawayo is 77 km and 469 km from Harare. The district is mostly in natural region four. This region experiences fairly low total rainfall (450–650 mm) and is subject to periodic seasonal droughts and severe dry spells during the rainy season. The rainfall is too low and uneven for cash cropping except in certain very favourable localities, where limited drought resistant crops can afford a side-line. The farming system, in accord with natural factors, should be based on livestock production, but it: can be intensified to some extent by the growing of drought resistant fodder crops.
