Despite the important role of Neglected and Underutilized Species (NUS) in diversifying agriculture, supporting traditional farming systems and improving food and nutritional security particularly in marginal lands, very little attention is being paid to their mainstreaming in national policies and institutions. Based on a detailed review of the regulatory frameworks governing the conservation, sustainable use and equitable sharing of benefits arising out of plant genetic resources and the circulation and registration of seeds and improved varieties, this paper discusses the extent to which the measures in place in India may favour or affect the conservation and use of NUS. In addition to these frameworks, in view of the major change realized by the 2013 National Food Security Act which has included coarse cereals in the country’s Public Distribution System (PDS), the paper also incorporates this latest policy in its analyses. A special focus is given to small millets, a group of species with unexploited economic and nutritional potential but extremely important for marginal communities’ food security and livelihoods. A set of policy recommendations and opportunities to explore are proposed to address the identified constraints with the purpose of creating a more supportive policy environment and enhancing the national capacity to promote NUS.  相似文献

The European Union is contemplating making the provision ofnutritional labels in food products mandatory. Using data collectedfrom food shoppers, we assessed consumers' valuation of nutritionallabels by analysing their willingness to pay a premium for abox of cookies with a nutritional label. On average, the meanwillingness to pay (WTP) for a box of cookies with a nutritionallabel is estimated to be about 11 per cent above the price ofthe box of cookies without a nutritional label. Consistent withprior expectations, our results also indicate a difference betweenthe WTP of individuals suffering from diet-related health problems(estimated mean 13 per cent) and those who do not suffer anydiet-related health problems (estimated mean 9 per cent).  相似文献

Abstract

The increase in food-related diseases in society has led to a variety of public policy and private sector initiatives, such as the use of nutritional labels. Although nutritional labels have been shown to be broadly effective in terms of informing food choice, their influence is moderated by a variety of factors, such as how information is conveyed and processed by consumers. Recent advances in technology might overcome these limitations. Using a choice experiment, this paper examines consumer preferences for alternative technological devices that may aid consumer processing of nutritional information on food packaging. The results show which attributes of the technology consumers prefer, and identifies three distinct segments of consumers (‘information hungry innovators’, ‘active label readers’, and ‘onlookers’), and differences between them in relation to their preferences, demographics, and psychographic characteristics. The identification of segments is a novel aspect of this research, and highlights the importance of finding more customised solutions to the communication of nutritional information – an issue to which technology can contribute.  相似文献

Organic and national brand manufacturers position their offerings as nutritious meals for adults and children. Do these brands serve as reliable signals of nutritional quality? To find an answer, this study analyzed a very popular, ready-to-eat breakfast cereal food category based on all the available data from 2011 (324 offerings) from a large UK grocery comparison website, mysupermarket.co.uk. The study shows that it is possible to find store and basic brand offerings that are almost identical to national brand offerings, but much cheaper and with less sugar (the main concern in cereal). Hedonic price regression analysis further confirms that brand and size explain most of cereal’s price variability, regardless of nutritional quality. The findings also reveal that low-sugar cereals are hard to find regardless of price, and almost all cereals targeted at children have high levels of sugar. A replication study (337 offerings in 2012) revealed that, on average, cereal sugar levels and prices increased, while nutritional value decreased.  相似文献
