African farmers have developed a range of practices in an effort to store sweetpotato roots and extend shelf-life. These include storage in soil, grass or ash, storage in pits, leaving roots in the ground and harvesting piecemeal as required, or processed into sun-dried chips. β-carotene, an important source of dietary vitamin A, is better retained in fresh storage than in dried chips or flour. Important lessons have been learned regarding pre-storage handling and sorting with respect to curing and pest control. New innovations and local knowledge on root and tuber crops offer the potential for consistent improvements in the shelf-life of sweetpotato in SSA. This poster compares storage innovations at the community level in Ghana and Malawi.
