EVIDENCE REPORT No 127: Reducing Hunger and Undernutrition

This case study examines the outcomes if interventions in Tanzania that have promoted the production and consumption of orange-fleshed sweet potato (OFSP) – a biofortified crop with the objective of reducing vitamin A deficiencies. The report contributes to policy efforts to promote nutrition-sensitive agriculture by providing lessons for the introduction of biofortified crops in Tanzania and elsewhere. The case study is particularly instructive because OFSP has been a flagship of biofortification efforts, and because Tanzania appeared to have high potential for uptake of the crop. The country is a major producer of sweet potato, although the vast majority of production is of the nutrient-poor white-fleshed varieties (WFSP) Sweet potato is an important food security crop for small farming households , particularly in Tanzania’s Lake Zone. The crop has the advantage of requiring little land and few inputs , and can be stored on-farm for several months. The crop also has commercial value, and white-fleshed varieties are available in urban markets throughout the year.
