This brief gives an overview of sweetpotato Action for Security and Health in Africa SASHA project.  Briefly the project started in 2009, with a goal of improving the food security and health of poor families in sub-Saharan Africa (SSA) by exploiting the untapped potential of sweetpotato. Further, by tackling the bottlenecks along the sweetpotato value chain that prevent the full exploitation of crop’s potential. The success of Phase I led to development of Phase II which has a strategic focus on adaptive research to break the remaining bottlenecks to unleashing the potential of sweetpotato for reducing undernutrition and food insecurity. In conclusion all these initiatives seek to develop the essential capacities, products, and methods to reposition sweetpotato in food economies to alleviate poverty and undernutrition in Africa.
