BACKGROUND The density of minerals and vitamins in food staples eaten widely by the poor may be increased either through conventional plant breeding or through the use of transgenic techniques, a process known as biofortification. OBJECTIVE HarvestPlus seeks to develop and distribute varieties of food staples (rice, wheat, maize, cassava, pearl millet,(More)
Biofortification is increasingly seen as an additional tool to combat micronutrient malnutrition. This paper presents, for the first time, evidence on the costs and potential benefits of biofortification for a large number of countries in Africa, Asia and Latin America. We use a modification of the Disability‐Adjusted Life Years framework to conclude that(More)
Deficiencies of vitamin A, iron, and zinc affect over one-half of the world's population. Progress has been made to control micronutrient deficiencies through supplementation and food fortification, but new approaches are needed, especially to reach the rural poor. Biofortification (enriching the nutrition contribution of staple crops through plant(More)
OBJECTIVE To estimate the potential impact of zinc biofortification of rice and wheat on public health in India and to evaluate its cost-effectiveness compared with alternative interventions and international standards. DESIGN The burden of zinc deficiency (ZnD) in India was expressed in disability-adjusted life years (DALYs) lost. Current zinc intakes(More)
HarvestPlus Technical Monographs are designed to provide a forum for HarvestPlus research outputs. Technical Monographs can be of two kinds: • state-of-the-art reviews that help to establish and define HarvestPlus research questions or • " gold standard " procedures to be followed in HarvestPlus research. HarvestPlus technical monographs are written by(More)
The success of biofortified staple crops depends on whether they are accepted and consumed by target populations. In the past 8 years, several studies were undertaken to understand consumers’ acceptance of foods made with biofortified staple crops. Consumer acceptance is measured in terms of their sensory evaluation and economic valuation of biofortified(More)
Vitamin A deficiency (VAD) persists in Uganda and the consumption of β-carotene-rich orange sweet potato (OSP) may help to alleviate it. Two large-scale, 2-y intervention programs were implemented among Ugandan farmer households to promote the production and consumption of OSP. The programs differed in their inputs during year 2, with one being more(More)
This study analyzes consumer acceptance of biofortified orange maize in rural Zambia by eliciting consumers’ willingness to pay. It attempts to examine the impact of nutrition information, comparing the use of simulated radio versus community leaders in transmitting the nutrition message, on consumer acceptance. Finally, it assesses whether product(More)
Vitamin A deficiency is a major health problem in Africa and in many other developing countries. Biofortified staple crops that are high in beta‐carotene and adapted to local growing environments have the potential to significantly reduce the prevalence of vitamin A deficiency. One such example is the orange sweet potato (OSP). Because of its distinctive(More)
Iron deficiency is a widespread nutrition and health problem in developing countries, causing impairments in physical activity and cognitive development, as well as maternal mortality. Although food fortification and supplementation programmes have been effective in some countries, their overall success remains limited. Biofortification, that is, breeding(More)
