Baseline study for impact assessment of high quality insect resistant cowpea in West Africa por Coulibaly, O., Aitchedji, C.C., Gbegbelegbe, Sika, Mignouna, H., Lowenberg-Deboer, J.

“…Availability of Bt cowpea lines with resistance to Maruca will contribute significantly to: (1) increased production and incomes, (2) improved nutrition, (3) enhanced soil fertility, (4) increased storability, and (5) decreased pesticide use.The study initiated by AATF and executed by the International Institute of Tropical Agriculture (IITA) and Purdue University aims to:1. elicit consumer preferences, acceptability, willingness to pay and adaptability of Bt cowpea to local conditions in west Africa 2. assess the competitiveness and potential market niches for Bt cowpea3. identify strategies for capacity building of west African seed organisations for Bt cowpea 4. assess the ex-ante economic impact of Bt cowpea at farm, country and region levels.Preliminary results show that: 1. information exchange and awareness are important for the adoption and large diffusion of Bt cowpea2. there is a high willingness to pay for Bt cowpea seed by farmers 3. given the potential of reducing health hazards by lowering the use of toxic synthetic pesticides, both farmers and consumers are willing to pay a premium price for Bt cowpea as an alternative to harmful cotton pesticides. …”
