New research from the International Initiative for Impact Evaluation (3ie) supports claim that uptake of biofortified vitamin A-enriched orange sweet potato (OSP) benefits the people of Uganda both in farming and in diet.
IFPRI-led research teams carried out two impact evaluations to assess OSP’s health impacts and farmers’ sustained adoption of it. The first impact evaluation found that the vitamin A status of deficient children improved after they consumed OSP. The second impact evaluation, which was supported by 3ie, showed that four years after HarvestPlus distributed OSP, farmers’ adoption and cultivation of it had stabilised at approximately 50 per cent in two out of three districts.
The International Initiative for Impact Evaluation (3ie) is an international grant-making NGO promoting evidence-informed development policies and programmes. We are the global leader in funding, producing and synthesising high-quality evidence of what works, for whom, why and at what cost. We believe that high-quality and policy-relevant evidence will help make development more effective and improve people’s lives.
We are part of the CGIAR Research Program on Agriculture for Nutrition and Health (A4NH) which helps realize the potential of agricultural development to deliver gender-equitable health and nutritional benefits to the poor. CGIAR is a global agriculture research partnership for a food-secure future. The HarvestPlus program is coordinated by two of these centers, the International Center for Tropical Agriculture (CIAT) and the International Food Policy Research Institute (IFPRI).
