Impact of NERICA Adoption on Rice Yield: Evidence from West Africa



There is an urgent need to accelerate the growth in domestic rice production in West Africa to reduce its unsustainable and risky dependency on rice imports. Also important is resistance to drought and other climatic risks in rice farming in West Africa where precipitation is low and uncertain. The improved drought-resistant upland rice varieties, NERICAs, were introduced to rice farming system in Côte d’Ivoire, Guinea, Gambia and Benin from the late 1990s through participatory varietal selection trials. Farmers then started disseminating them through their informal channels. The objective of this chapter are to assess the characteristics of NERICA adopters and the potential contribution of the NERICA varieties to the improvement of land productivity in upland rice farming by applying the potential outcome framework to farm household survey data collected in the four West African countries.
