Uasin Gishu is mainly agricultural in character, dominated by farms of maize, sunflower, wheat, pyrethrum, potatoes and barley. Its Arable land covers 2,995 km2 of which 910 km2 is under maize; 4.5 million bags are harvested yearly and by far the most important cereal grown in the County. It also produces more than one-third of total wheat in Kenya. Stunning forests cover 29,802 ha; 13,184 ha is under plantation, and 16,618 ha is indigenous forests.
There is a sharp contrast in the landscape as you move from these highlands down Kerio Escarpment which links the cool and humid Uasin Gishu with the warm and semi-arid Elgeyo Marakwet County; and over the Nandi Hills which separate it from Kisumu County. This provides an exceptional opportunity to appreciate the ecological range in Kenya.
