Sweetpotato for Profit and Health Initiative (SPHI)
The SPHI is a multi-partner, multi-donor initiative that seeks to reduce child malnutrition and improve smallholder incomes in 10 million African families by 2020 through the effective production and expanded use of sweetpotato.
The first five-year phase (2010-2014) focused on Proving the Potential, building up the supply of adapted varieties and testing delivery models. The second five-year phase (2015-2019) focuses on Achieving the Potential, ensuring that effective “seed” systems are delivering improved planting material to 10 million sub-Saharan African households in 17 countries.
The SPHI Steering Committee is committed to partnership for collective impact. The committee provides strategic guidance and undertakes high level advocacy and resource mobilization for the initiative. It is co-led by the International Potato Center (CIP), represented by Jan Low and Forum for Agricultural Research in Africa (FARA), represented by Yemi Akinbamijo.
