County Ecological Conditions
The County has two main ecological zones:
- The highlands (upper zone) comprise of Maara and Chuka which receive adequate rainfall for agriculture.
- The semi-arid (lower zone) covers Tharaka and receives less rainfall suitable for livestock production.
Poor methods of farming and soil conservation, charcoal burning and overgrazing have left the earth bare and rocky. The sloping areas have experienced uncontrolled soil erosion, which has resulted in deep gullies across the landscape especially in Tharaka.
The drainage pattern consists of rivers and streams that ultimately drain into the Indian Ocean through Tana River.
