50,000 Farmers in 13 Countries: Results from Scaling up the System of Rice Intensification in West Africa is a publication by Dr Erika Styger and Dr Gaoussou Traore, written for the West and Central Africa Council for Agricultural Research and Development, (CORAF/WECARD), Africa's largest sub-regional research organization. The 120-page book documents the results of using the SRI approach in rice farmers’ fields in 13 West African countries between 2014 and 2016: Benin, Burkina Faso, Côte d’Ivoire, the Gambia, Ghana, Guinea, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, and Togo.
Our SRI-Rice Center was the technical lead on this World Bank-funded project, which Erika Styger and Devon Jenkins worked on from 2013 to 2016.
