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...

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...

The paper aims to contribute to the longstanding technology-push vs. demand-pull debate and to the literature on renewable energy diffusion and renewable energy policy assessment. The authors argue that in addition to the traditional push-pull dichotomy, the drivers of technological change must...

In causal inference for longitudinal data, standard methods usually assume that the underlying processes are discrete time processes, and that the observational time points are the time points when the processes change values. The identification of these standard models often relies on the...

In many community-based surveys, multi-level sampling is inherent inthe design. In the design of these studies, especially to calculate theappropriate sample size, investigators need good estimates ofintra-class correlation coefficient (ICC), along with the cluster size,to adjust for variation...

Vitamin and mineral deficiencies are a significant health problem in much of the developing world, causing illness, disability, mortality and reduced productivity. Biofortification of staple food crops has been proposed as a cost-effective solution. This paper calculates disabilityadjusted life...

Food fortification presents practical and cost-effective alternative to the fight against micronutrient malnutrition. Vitamin A deficiency and lack of iron bears the greatest economic importance in Kenya. Consequently, the National Food Security and Nutrition Policy in Kenya focus on pilot...

This paper estimates country-specific costs and benefits of scaling up key nutrition investments in Nigeria. Building on the methodology established in the global report scaling up nutrition: what will it cost? Authors first estimate the costs and benefits of a nationwide scale up of ten...

"Agriculture is fundamental to achieving nutrition goals: it produces the food, energy, and nutrients essential for human health and well-being. Gains in food production have played a key role in feeding growing and malnourished populations. Yet they have not translated into a hunger-free world...
