Can genetic engineering for the poor pay off? An ex-ante evaluation of Golden Rice in India AgEcon
Stein, Alexander J.; Sachdev, H.P.S.; Qaim, Matin.
Genetic engineering (GE) in agriculture is a controversial topic in science and society at large. While some oppose genetically modified crops as proxy of an agricultural system they consider unsustainable and inequitable, the question remains whether GE can benefit the poor within the existing system and what needs to be done to deliver these benefits? Golden Rice has been genetically engineered to produce provitamin A. The technology is still in the testing phase, but, once released, it is expected to address one consequence of poverty " vitamin A deficiency (VAD) " and its health implications. Current interventions to combat VAD rely mainly on pharmaceutical supplementation, which is costly in the long run and only partially successful. We develop a...

Ex-Ante Evaluation of Nutrition and Health Benefits of Biofortified Cassava Roots in Nigeria: The Dalys Approach AgEcon
Manyong, Victor M.; Bamire, A.S.; Sanusi, I.O.; Awotide, D.O..
Cassava is a major staple that supplies more than 50% of daily energy to more than 200 million persons in sub-Saharan Africa (SSA). Cassava roots are known to be low in micronutrients such as vitamin A, iron, and zinc. Micronutrient deficiencies threaten the lives of millions of poor households and those located in remote rural areas of SSA often not targeted by fortification programmes. This paper presents results from an ex-ante evaluation of nutrition and health benefits of increased vitamin A status of cassava roots through biofortification for at-risk-target-groups using the disability-adjusted life years (DALYs) approach. Results showed that Vitamin A deficiency (VAD) causes an annual loss of about 553,000 years of “healthy” life in Nigeria with...

Health impact assessment of folate biofortified rice in China AgEcon
De Steur, Hans; Gellynck, Xavier; Storoshenko, Sergei; Liqun, Ge; Lambert, Willy; Van der Straeten, Dominique.
Introduction: As folate deficiency is mainly caused by the dependency on folate-poor staple crops, such as rice, the implementation of rice with a high level of natural folate could be a successful pro-rural and pro-poor intervention strategy to reduce folate deficiencies in China, where about 260 million people are considered to be folate deficient. Consuming folate biofortified rice instead of conventional rice could prevent someone from negative health outcomes of folate deficiency, such as megaloblastic aneamia and neural-tube defects. Especially for poor Chinese women of childbearing age, folate biofortification could be important to prevent them from having a baby with a neural-tube defect, the main adverse health outcome. As Northern and Southern...

Potential Impacts of Golden Rice on Public Health in India AgEcon
Stein, Alexander J.; Sachdev, H.P.S.; Qaim, Matin.
Vitamin A deficiency (VAD) affects millions of people world-wide, causing serious health problems. Golden Rice (GR), which has been genetically engineered to produce beta-carotene, is being proposed as a remedy. While this new technology has aroused controversial debates, its nutritional impact and cost-effectiveness remain unclear. We determine the current burden of VAD in India from a public health perspective,and simulate the potential alleviating impact of GR using representative household food consumption data. Given broad public support, GR could more than halve the overall burden of VAD. Juxtaposing health benefits and overall costs suggests that GR is very costeffective.

Potential Impacts of Iron Biofortification in India AgEcon
Stein, Alexander J.; Qaim, Matin; Meenakshi, J.V.; Nestel, Penelope; Sachdev, H.P.S.; Bhutta, Zulfiqar A..
Iron deficiency is a widespread nutritional problem in developing countries, causing impaired 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 crops for higher micronutrient content, is a relatively new approach. We propose a methodology for ex-ante impact assessment of iron biofortification, which builds on disability-adjusted life years (DALYs) and a large household data set. Our analysis of iron-rich rice and wheat in India indicates sizeable potential health benefits. The cost-effectiveness of iron biofortification compares favourably with other...
