Agriculture is one of Zambia’s economic drivers and a mainstay of the livelihood of a larger proportion of the country’s population. Agricultural production is mainly dependent on seasonal rain-fed cultivation with maize as the principal staple food crop. Crop diversification can be used as a tool to augment farm income, generate employment, alleviate poverty and conserve soil and water resources. In striving to improve food security and minimize risks associated with heavy dependence on maize monoculture, the Zambian government has been gradually promoting diversification into high-value crops of late. The Farmer Input Support Program has led to reduced crop diversification rates because of its biased support towards maize production. There is no access to subsidised inputs and government-driven consumption market as well as substantial extension service for non-staple food crops.
