abstract

  • In a time of increasing scrutiny about the usefulness of investments in agricultural research, impactassessment studies assist to demonstrate the value of continued investments in research. Lessonslearnt from impact assessments can be used to improve future research strategies, plans and management.This paper reviews and synthesizes the findings of various studies on the adoption andimpact of the research on sorghum and millet technologies in West and Central Africa (WCA). Thereview covers Burkina Faso, Cameroon, Chad, Mali, Nigeria and Niger, where relatively morebreeding research has been conducted. Furthermore, the information presented in this paper is mainlydrawn from the diffusion and impacts of varieties generated by ICRISAT and the national agriculturalresearch systems (NARS) of WCA. Findings from reviewed studies show that returns to research(and diffusion) investments are quite high, but the performance varies across countries. Theseresults could be of use to policy makers, donors and other scientists within the region of WCA. Thisfundamental information about the levels of adoption and impact of sorghum and millet is criticalfor priority setting and impact assessment. However, the results of the studies reviewed also indicatethat if improved technology is to make a meaningful impact at the farm level, it must beaccompanied by at least three complementary factors: (1) an effective extension service, (2) anefficient inputs distribution system, and (3) appropriate economic incentives
