Cashew nut cultivation in Kenya developed primarily in coastal and near-coastal regions, particularly in Mombasa, Kilifi, and Malindi districts, where agroclimatic conditions matched the crop's requirements. The cashew tree, introduced from its native Western hemisphere, found suitable growing conditions in Kenya's lowland tropical zones with their warm temperatures and moderate to high rainfall patterns during the growing season.
Commercial cashew cultivation expanded gradually from the 1950s onward, accelerated by colonial government promotion of cash crops suited to coastal soils and climate. Early plantations established by both European settlers and later by Kenyan farmers demonstrated the economic viability of cashew production, particularly as international demand for cashew nuts remained consistently strong in global markets. The crop generated valuable foreign exchange through export of processed cashew kernels to European, North American, and Asian markets.
The processing of raw cashew nuts into edible kernels required specialized infrastructure. Early processing was conducted abroad, with Kenya exporting raw cashew nuts in shell. During the 1970s and 1980s, the government invested in domestic cashew processing capacity to increase value addition and employment. Processing factories, concentrated in coastal towns, employed hundreds of workers in the labor-intensive task of extracting kernels from the hard cashew shell, which required both mechanical processes and skilled hand labor.
Cultivation practices adapted cashew production to local conditions through selection of suitable landraces and spacing systems appropriate for intercropping with coconuts and other perennial crops. The cashew byproducts including cashew apple (the accessory fruit attached to the nut) were utilized as livestock feed or for fresh consumption, adding to the crop's overall productivity and economic value.
Market dynamics shaped cashew farming profitability significantly. Price fluctuations in international markets affected farmer returns and investment in plantation maintenance. Competition from other cashew-producing nations including Tanzania, Mozambique, and India influenced Kenya's export volumes and market share. Despite these fluctuations, cashew remained an important income source for coastal farming communities throughout the late 20th century.
Environmental and social considerations shaped the sustainability of cashew cultivation. Competition for land between cashew plantations and other uses, particularly as coastal populations grew, created tensions between agricultural expansion and alternative land use patterns. Smallholder farmers integrated cashew trees into mixed farming systems alongside coconuts, mangoes, and other tree crops, creating agroforestry landscapes that provided multiple sources of income and food security.
