Maize, millet, rice, and sorghum are the major cereal crops in West Africa, yet yields from these crops are very low compared to the world average and even other regions within Africa. A changing climate will challenge production systems already under pressure to increase output to feed a growing population. IFPRI, with the support of the European Commission, The Bill and Melinda Gates Foundation, and Germany, launched the book West African Agriculture and Climate Change, a collaboration between IFPRI, CGIAR’s Climate Change, Agriculture, and Food Security (CCAFS) research program, the West and Central African Council for Agricultural Research and Development (CORAF/WECARD), and national scientists from the region, uses advanced modeling and available data to develop future scenarios exploring the range of climate change consequences for agriculture, food security, and resource management and offers recommendations to national governments and regional agencies. It offers, for the first time, country-by-country climate data and analysis for Benin, Burkina Faso, Cote d’Ivoire, Ghana, Guinea, Liberia, Niger, Nigeria, Senegal, Sierra Leone, and Togo. The research has received wide media coverage in West African countries and has been featured on the website of the US State Department.
