Overview of Nyandarua County

Nyandarua county is an agriculturally-rich zone located on the north-western part of the former Central Province, west of the Aberdare Mountain Ranges.

Nyandarua, Kenya

It borders five counties; Lakipia to the north and north east, Muran'ga and Nyeri to the east, Nakuru to the west and south west, and Kiambu to the south.

It is located about 100km from Nairobi.

The name Nyandarua means 'pegged hide' in the Gikuyu language perhaps because of the Aberdare Mountain Ranges’ resemblance to an animal skin pegged out to dry.

Religion and Traditional Culture

Majority of people living in Nyandarua County are Christians, with a small number of Muslims being present in major towns.

The Kikuyu people speak Gikuyu; a language widely spoken across the country even in major towns where a majority of people speak Kiswahili. Many Kikuyus also speak English and Kiswahili, and they are among the most educated ethnic group in Kenya.

They traditionally believed in a single god, called Ngai (the provider), living at the top of Mount Kenya. However, most Kikuyus have abandoned their traditional beliefs for Christianity. Top Christian denominations in the county include Roman Catholic, Anglican, PCEA, Assemblies of God and other protestant churches.

Githeri (maize and beans), irio (mashed beans and potatoes) and mukimo (mashed green peas and potatoes) are the staple food for the Kikuyu people.

Major Towns

Ol Kalou:

Is the biggest town in the county and is located about 120km from Nairobi, along the Nairobi-Nyahururu road. It is the headquarters of the Nyandarua County. Trade of farm produce is the main economic activity in Ol Kalou.

Farmers in the county mainly sell their products to traders from Nairobi, Nakuru, Nyeri, Embu, Kirinyaga and Thika. Most of these farmers practise subsistence farming and therefore do not have the capacity to sell directly to the consumers of their produce.

Other major urban centres are Mairo Inya, located four miles east of Thomson’s Falls and Engineer town in North Kinangop. Like Ol Kalou, farming is the backbone of Mairo Inya and Engineer economy.

Climate and Weather

Nyandarua County has predictable weather patterns with temperatures ranging between 12°C during the cold months (June and July) and 25°C during the hot months (January and February).

The county receives between 700mm and 1500mm of rainfall annually. It has two rainy seasons; March-April-May (long rains) and November (short rains).

Economic Activities

Agriculture is the backbone of the Nyandarua County economy, thanks to the county’s fertile soils and favourable climate.

Nyandarua, Kenya farm

The county is considered the bread basket of Kenya because of its high production of potatoes, cabbages, maize and beans that are sold in Nairobi and most other towns in the country. Other crops that flourish in Nyandarua include carrots, kales, tomatoes and peas.

The county was a leading producer of pyrethrum in the 1990s, but production of the crop has since gone down due poor management of the affairs of the sub-sector. In recent years, Nyandarua has attracted floriculturists who have established large flower farms in the county. Some of the largest flower farms in the county include Suera, Prima Rosa and Balaji. Nyandarua flowers are mainly grown for export to Holland, UK and Germany.

Small-scale farmers are yet to make entry into the sub-sector due to the high costs associated with floriculture. Livestock rearing is also a major economic activity in Nyandarua. Farmers in the county engage in dairy farming, sheep rearing, beef production as well as poultry. These products are sold to traders from Nairobi and other neighbouring towns.

Health Facilities

Nyandarua County has more than 100 healthcare facilities serving the residents of the county. Notable hospitals in the county include Nyahururu District Hospital and JM Kariuki Memorial Hospital (formerly Ol Kalou District Hospital).
