Like many Bantus the Akamba were originally hunters and gatherers, became long distance traders because of their knowledge of the expansive area they inhabited and good relations with neighbouring communities as well as excellent communication skills, later adopted subsitence farming and pastoralism due to the availability of the new land that they came to occupy. The Akamba traded in locally produced goods such as sugar cane wine, ivory, brass amulets, tools and weapons, millet, and cattle. The food obtained from trading helped offset shortages caused by droughts and famines experienced in their Kamba land. They also traded in medicinal products known as ‘Miti’ (literally: plants), made from various parts of the numerous medicinal plants found on the Southeast African plains. Maingi Ndonye Mbithi, commonly referred by his peers and locals as Kanyi, from Kimutwa village in Machakos was best known for his concoction of herbs mixed with locally fermented brew (kaluvu) with the ability to heal cancerous boils (Mi’imu). The Akamba are still known for their fine work in wood carving, basketry and pottery and the products . Their artistic inclination is evidenced in the sculpture work that is on display in many craft shops and galleries in the major cities and towns of Kenya.
In the mid-eighteenth century, a large number of Akamba pastoral groups moved eastwards from the Tsavo and Kibwezi areas to the coast. This migration was the result of extensive drought and lack of pasture for their cattle. They settled in the Mariakani, Kinango, Kwale, Mombasa West (Changamwe and Chaani) and Mombasa North (Kisauni) areas of the coast of Kenya, creating the beginnings of urban settlement. They are still found in large numbers in these towns, and have been absorbed into the cultural, economic and political life of the modern-day Coast Province. Several notable businessmen and women, politicians, as well as professional men and women are direct descendants of these itinerant pastoralists
