The county can be divided into five Agro- Ecological Zones (AEZ), which define areas that have similar characteristics such as annual mean temperatures, vegetation and humidity.
Coconut-Cassava Zone: This zone has the highest potential for crop production in the county spreading along the coastal uplands and low-level coastal plains. Major farming activities include tree cropping (mango, citrus, cashew nuts, and coconuts), vegetables (chilli, brinjals, okra etc.), food crops (maize, bananas, cowpeas, green grams etc.) and upland rice. Dairy farming also does well in this zone. It has an average precipitation of 1,300mm per annum and mean annual temperature of 24 0C.
Lowland Ranching: It varies in altitude of 90-300m with mean annual temperature of 270 C and annual precipitation of 350-700mm. Major activities within this zone include ranching and wildlife.
Coconut Cashew nut-Cassava Zone: This zone is mainly found in Kilifi South and North Constituencies and is the smallest of all the zones. It varies in altitude from 30-310m above sea level with mean temperature of 270 C and annual precipitation of 900mm per annum.
The area has potential for those crops grown in the coconut-cassava zones and cashew nut- cassava zones.College of Biological and Physical Sciences School of Biological Sciences
