NERICA Adoption and Impact:Summary of findings from four countries.

Africa Rice Center (WARDA) 2008

Research and Development Brief. August 2008

The Nerica (New Rice for Africa) rice varieties is a group of rice varieties resulting from interspecific crosses between the Oryza sativa rice species from Asia and the locally adapted and multiple-stress resistant Oryza glaberrima African rice species. They are the outputs of the interspecific hybridization breeding program started in 1991 by the Africa Rice Center (WARDA). The Nerica varieties promise to raise significantly the productivity, income and food security of of rainfed upland rice farmers in sub-Saharan Africa. The Nerica varieties were introduced to rice farmers starting in 1996 in West Africa through Participatory Varietal selection (PVS) trials. To date up to eighteen Nerica varieties have been disseminated in numerous countries across Sub-Saharan Africa through informal channels by farmers and by development projects including the $35 Nerica dissemination project funded by the African Development Bank (starting in 2004). Studies on the adoption and impact of the Nerica varieties are being conducted in 9 countries. In this brief we summarize the main findings on the adoption and impact of Nerica in four countries: Benin, Cote d’Ivoire, Guinea, and Gambia. The methodology used in the studies is briefly described at the end of the document.
