Akzeptanz und Erfolg kleinräumiger Systeme der Lebensmittelversorgung im urbanen Umfeld am Beispiel Stuttgart : empirische Untersuchungen von Verbrauchern und Unternehmen
(2012) Gebhardt, Beate
The working paper analyzes the acceptance of short-chain food supply systems by consumers and companies in Stuttgart, the provincial capital of Baden-Württemberg, based on theoretical considerations and empirical studies carried out by the Chair of Agricultural Markets and Marketing at the University of Hohenheim. The key questions of the empirical studies focus on the following points: How does the city population reflect the importance of regional foods? What are the attitudes and purchase behavior of urban consumers in regard to regional food or self production and what importance can the subjects gain in the future? Of which importance is regional food to local merchants? assortment in Stuttgart and which future developments can we derive?
Obsoleszenz - auch ein Thema bei Lebensmitteln : Ergebnisse einer Expertenbefragung
(2018) Gebhardt, Beate; Ding, Jana-Lisa; Feisthauer, Philipp
Obsolescence is a topic that also concerns food products. Popular science has speculated that to a more or less significant extent, actors involved in food value chains were responsible for preliminary spoilage of food products. This speculation is true. Research and food experts in the field confirmed this during an expert survey conducted in 2015. This paper presents this survey. Experts confirm the main issue of this analysis which sheds light on the relevance of the following idea: Is obsolescence a topic regarding food products or does it only concern (technical) consumer goods? Only the latter is currently under debate. In total, 19 researchers and practicians from food value chains were surveyed and the majority shares this view. However, not all of them agree. The topic polarises researchers in particular. Eventually, issues such as the waste of ressources and social disparity due to food waste are not very disputed, irrespective of the reasons they emerged, but rather those responsible for the issue as well as the term that is to be used when food products spoil or are disposed preliminarily: obsolescence, food waste, avoidance, or other. The ensuing question focuses on this by addressing the advantages or added value if food waste was introduced into the debate on obsolescence or, on the contrary, if food waste was perceived in light of the debate on obsolescence. In this regard, we must emphasise the following key topics: 1) Avoiding arbitrary authority of definition: Shifting a term and generating authority of definition regarding (planned) obsolescence in merely specific areas is arbitrary. There are no objective reasons to apply obsolescence solely to consumer goods or technical devices. Irrespective of the type of industry, product, or the product’s shelf life, the reasons and circumstances for which products spoil preliminarily are similar in many aspects. Problems and reasons of unnecessary use of resources arise along the value chain due to processes and practices on all markets of modern and innovative societies. 2) Corrective of consumer responsibility: Addressing manufacturers and retailers represents a corrective when handing over responsibility for food waste. Especially in the food sector, to much responsibility is falling on consumers. In general, the aims of mitigating waste of resources are disputed. It should not pursue the way of least resistance and address primarily consumers. The corrective of consumer responsibility enables a corrective for solution-oriented approaches with greater diversity along the whole food value chain. 3) Problem-centred revision of definitions: In light of food waste, the use of natural materials and the role of agriculture are often neglected, described as inevitable, or excluded by definition or regulation (e.g. harvesting losses). However, obsolescence and its clear distinction between natural and artificial (planned) obsolescence does not fundamentally alter the view on natural resources of food and their use. Moreover, the necessity to critically revise regulation (e.g. the German Waste Management and Product Recycling Act) becomes clear. 4) Learning from and with each other: Changes in perspective and exchange among experts in debates on obsolescence and food waste are the bedrock to learn about tools, solutions, as well as experiences and mistakes made by others (e.g. proposal for a shelf life indication for technical devices without referring to experience with best-before indications of food products). Topics for further research include interdependencies and conflicts of targets which concern innovation for sustainability, shortage of product life cycles as well as the establishment of standards as means for more transparency to check their contribution to obsolescence and identify approaches for more appreciation in the overall concept considering all market participants.
Public attitudes towards genetically modified provitamin A Cassava in Brazil
(2010) Gonzalez Rojas, María Carolina; Qaim, Matin
Cassava is a basic staple food crop with worldwide distribution, mainly in developing countries. A fundamental source of energy for the poor, cassava grows well on marginal soils and resists pests and drought. In Latin America, Brazil is the largest cassava producer and consumer. The crop is especially important in the northeastern (NE) part of the country, where poverty and malnutrition rates are higher than in the rest of the country. However, despite the crop?s dietary importance, relatively little is known about consumer preferences, which holds true not only for Brazil but also for other developing countries. Understanding consumer preferences is crucial for technology and market development, especially in the context of provitamin A biofortification, as this entails a yellow-colored cassava root. The first article, titled ?Consumer Preferences for Cassava Characteristics in Pernambuco, Brazil?, addresses this research gap. Consumer preference for different cassava attributes are analyzed using household survey data and econometric techniques. A hedonic price model is specifically developed to estimate the values that consumers place on specific product attributes. Results show the most important characteristics for local consumers are ease of peeling, time of cooking, and texture; however, root color and size as well as market location are other relevant attributes in determining price. The second article, titled ?Consumer Acceptance of Second-Generation GM Foods: The Case of Biofortified Cassava in the Northeast of Brazil?, examines whether consumers would appreciate provitamin A biofortification and accept GM cassava. For this purpose, stated preference data, collected as part of the household survey, are used. Findings suggest that attitudes towards GM biofortified cassava are generally quite positive among local consumers. Three-quarters of all respondents in the survey said they would support the introduction of this new technology. Using contingent valuation techniques, consumers were shown to be willing to pay an average price premium of 64% for GM biofortified cassava. This is high but not unrealistic, given that vitamin A deficiency and related health problems are widespread in NE Brazil. In addition, a contingent ranking choice experiment was used to better understand the trade-offs between different cassava characteristics and estimate the partial willingness to pay (WTP) for each relevant attribute. For the provitamin A attribute alone, the average consumer is willing to pay a large premium of 160%. However, a discount is required for the color change of cassava from white to yellow (-29%), and an additional discount results from the fact that the cassava is genetically modified (-61%). These are important findings for biofortification research programs that have to make choices between conventional and GM breeding techniques. It is noted that a significantly positive WTP does not imply that GM provitamin A cassava will indeed be sold at a premium. The technology is being developed by the public sector with the aim to reduce malnutrition among the poor, so a low price should be sought to enable easy access. Hence, the WTP survey is a tool to better understand consumer attitudes rather than an approach to develop a pricing strategy for a new commercial product. The third article, titled ?Stakeholder Positions toward GM Food: The Case of Vitamin A Biofortified Cassava in Brazil?, gathers experiences from around the world and shows that stakeholder positions can crucially influence the efficiency of GM regulatory approaches and the success of new technologies. This research builds on a survey of a large range of local stakeholders. Overall, stakeholder perceptions about GM foods are relatively positive in Brazil. Statistical analysis shows that three groups of stakeholders can be distinguished: those in favor of GM crops, those against, and those that have a more or less neutral position. Representatives of local and multinational industries and those of several governmental entities belong mostly to the first group; international and national NGOs form the second group, while scientists are mostly found in the third group. Information sources and institutional/personal relationships influence individual stakeholder positions, as do socio-demographic characteristics, such as the level of education and age. An important result is also the high level of trust that stakeholders in Brazil have, in general, in the country?s research and academic sectors. Therefore, taking into account the relevance of information and the role played by the research sector, an effective system of distributing GM crop information via government agencies and/or public media is necessary to complement the knowledge of consumers so that they can make their own informed decisions.
