Kajiado County is located at the southern tip of the former Rift Valley Province. The landscape of Kajiado County consists of plains plus some volcanic hills and valleys. The region is very dry with no continually flowing rivers and is officially designated as semi-arid. Annual rainfall varies between 500 and 1,250mm.
Pastoralism plays a major role in contributing to the economy of Kajiado County. Livestock production has been on an increase because of the growing commercialization of the pastoral economy. Further efforts to develop the processing capacity for dairy and beef products coupled with improvements in livestock marketing boards would see this industry take the county to greater levels. Agriculture is practised in some parts of the county as more and more of the indigenous people of the county move from relying solely on livestock for their incomes to substituting this with subsistence agriculture. Efforts to develop irrigation projects in the region would see this agricultural production increase and enable the county to be food secure.
Some notable resources in the county includes the Amboseli National Park a popular tourist destination rich with wildlife and diverse ecosystem of flora and fauna and mineral resources particularly Soda ash from Lake Magadi.
