Can genetic engineering for the poor pay off? An ex-ante evaluation of Golden Rice in India 31
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...

Economics of Biofortification 31
Qaim, Matin; Stein, Alexander J.; Meenakshi, J.V..
Micronutrient malnutrition affects billions of people world-wide, causing serious health problems. Different micronutrient interventions are currently being used, but their overall coverage is relatively limited. Biofortification – that is, breeding staple food crops for higher micronutrient contents – has been proposed as a new agriculture-based approach. Yet, as biofortified crops are still under development, relatively little is known about their economic impacts and wider ramifications. In this article, the main factors that will influence their future success are discussed, and a methodology for economic impact assessment is presented, combining agricultural, nutrition, and health aspects. Ex ante studies from India and other developing countries...

Health benefits of biofortification - an ex-ante analysis of iron-rich rice and wheat in India 31
Stein, Alexander J.; Meenakshi, J.V.; Qaim, Matin; Nestel, Penelope; Sachdev, H.P.S.; Bhutta, Zulfiqar A..
Hunger is acknowledged to impose a heavy burden on humankind with severe negative health consequences. Micronutrient malnutrition, or "hidden hunger", is an even more widespread problem, to which economic development and income growth alone are not expected to provide a solution any time soon. Existing micronutrient interventions like pharmaceutical supplementation or industrial fortification have their limitations and can be complemented by a new approach: breeding food crops for higher micronutrient densities. Knowledge about the cost-effectiveness of this new tool, also termed biofortification, is scarce. In this study, a framework for economic impact analysis is developed, which is then used for evaluation of iron-rich rice and wheat in India. Health...

Mikronährstoffmangel? Ein gesundheitsökonomischer Bewertungsansatz 31
Zimmermann, Roukayatou; Stein, Alexander J.; Qaim, Matin.
Micronutrient malnutrition is a serious problem in many developing countries. Recently, agricultural technologies have been discussed as a complement to other intervention programs. Plant breeding, targeted at developing staple foods with higher contents of essential vitamins and trace minerals, could benefit the poor in particular. Yet, the economic repercussions of such innovations are still unclear. Because traditional models of technology assessment are inappropriate to capture the specific ramifications, we suggest a health economics approach. Herein, micronutrient malnutrition is understood as a phenomenon that causes health costs through diseases and premature deaths. Details of the methodology are discussed within an ex ante study of Golden Rice in...

Potential Impacts of Golden Rice on Public Health in India 31
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 31
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...
