Economic Welfare Change Attributable to Biological Control of Lepidopteran Cereal Stemborer Pests in East and Southern Africa: Cases of Maize and Sorghum in Kenya, Mozambique and Zambia

This study adopted the economic surplus model to evaluate the impact of the biological control program (BC), implemented by the International Centre of Insect Physiology and Ecology (icipe), on cereal crops production in Kenya, Mozambique and Zambia. The BC was implemented in East and Southern Africa between 1993 and 2008, with the aim of helping small scale farmers to reduce cereal yield losses due to stem-borers and improve their well-being. Findings show that BC-intervention substantially contributes to consumer and producer welfare in the three countries. The net present value of $US 271.76 million, the attractive Internal Rate of Return of 67%, as well as the estimated Benefit Cost Ration of 33.47, imply the efficiency of investment in BC-program. Moreover, 0.35%, 0.25% and 0.20% of poor are yearly lifted out of poverty respectively in Kenya, Mozambique and Zambia. These findings underscore the need for increased investment in BC in the sub-region.
