Adoption and impact of an award winning post-harvest technology: The ASI rice thresher in the Senegal River Valley

In Senegal, one of the highest rice import-dependent countries in Sub-Saharian Africa, double cropping is recommended in the new national program for the Great Offensive for Food and Abundance (GOANA) to boost rice production. This target impels the respect of cropping calendar by using improved technologies like the ASI thresher-cleaner. The causal or treatment effect framework (ATE and LATE) is used to estimate the ASI adoption rate and impact. The results show that the true ASI adoption rate would be 86 % if all the population of irrigated rice farmers were exposed to it. The socioeconomic characteristics that increase the probability to adopt the ASI thresher are farmer experience, farm size, and participation to ASI field experiments and/or contact with service providers, and lag between ASI invention (1997) and first awareness. Indeed, irrigated rice farmers who recently become aware of the ASI thresher represent a highly potential group of adopters. The results show, as well, that the ASI thresher adoption could help irrigated rice farmers to cope with labour scarcity by decreasing significantly the number of workers needed. The labour-gain would be 22 man-days per hectare in the subpopulation of potential adopters.
