Genetically modified food and crops : perceptions of risks

Hall, Clare R. January 2010 (has links)
The debate around genetically modified food and crops has proved to be complex and far-reaching, involving diverse stakeholder groups and many issues. Although the extent of global uptake of GM crops has been substantial (23 countries and 114.65 million hectares by 2007), it is significant that four countries are responsible for 86% of all GM plantings, and that a number of key food markets (for example the EU and Japan) remain largely "GM-free‟. This suggests that there is reluctance on the part of many countries to embrace GM technology. There are likely many reasons for this, but one significant issue is that of the perception of the risks associated with the technology. There is a distinction between risk that exists in the world and that can be measured (objective risk) and risk that is perceived by an individual to exist and that is constructed by them based on their values and preferences. When technical measurement of actual risks is not possible, peoples‟ own perceptions of risks become important. This thesis aims to investigate the topic of risk perceptions associated with GM food and crops. Different stakeholder groups have been targeted, and a range of methodologies from a variety of disciplines have been employed to investigate what factors can be shown to influence risk perception. A range of factors were identified from existing literature, as having potential impact on risk perceptions. A number of these were investigated, some of which were found to have some influence on levels of risk perception. Results demonstrate that factors influencing peoples‟ perceptions of risk relating to GM food and crops, include the uncertainty associated with the technology, and trust in regulators, policy makers and others with control over the future development of the technology. Other factors found to be important to levels of risk perception held by different stakeholder groups, were a range of socio-demographic and cultural variables, the relationship between perceived risks and benefits, the equity of impacts, and the influence of third parties. There are a number of implications for the development of the GM debate arising from the findings. First, as there are socio-demographic and cultural factors linked to the perceptions of risk associated with GM technologies in food and agriculture, it is important to recognise that different people will react differently to the technology. Specifically, results from this thesis show that it may be that men, those who are more highly educated, those with a less ecocentric worldview, and those living in urban areas, are likely to respond more favourably to targeted promotional campaigns. As regards the farming community, results show that the first farming adopters are likely to be those who are both owners and tenants, not in an urban fringe location, potato growers, and not barley growers. Second, this thesis provides evidence that third parties are particularly important to farmers, thus it is crucial to recognise that there is potentially a long chain of action and reaction amongst many different stakeholders and actors impacting on farmers' levels of risk perception, and hence willingness to adopt the technology. Third, results from this research demonstrate that the linked issues of the relationship between risks and benefits, and the equity of (positive and negative) impacts, require that all stakeholders are content that they will receive a share of the benefits (if any) to be derived from the technology, and that neither they nor any other group of stakeholders are unduly impacted by the risks or negative impacts (if any) of the technology. Important here is the recognition that perceptions are as important as actual impacts. Fourth, the issue of trust has been shown by the results obtained by this research to be extremely important to peoples' perceptions of risk. It can be concluded that trust is of wider social and political importance that relates to the need to ensure greater democratisation of decision-making in order to re-establish trust in authorities. In the case of GM food this may require a rethinking of the EU legislation relating to the technology. This also relates to point below about the delivery of messages and education. Information sources must be trusted by those at whom the messages are aimed. More importantly though, if people are to trust decision making processes, there needs to be stakeholder involvement at an early stage of decision making, that allows some impact on decisions taken. In the case of the GM debate it may indeed be too late as decisions about the technology, its applications, the regulatory processes and its inclusion within the food chain are well established. Perhaps the best that can be hoped for is that lessons will be learnt and applied to future technology developments of relevance to the food chain, such as, nano-technology. Finally, this thesis has shown that uncertainty is central to peoples' perceptions of risk. This could be addressed through a combination of additional research into what is uncertain to people, the impacts and implications of the technology, more effective dissemination of existing knowledge, and impartially delivered messages and education strategies from trusted sources that address the concerns that people have about the technology. Importantly however there must be an acknowledgement that uncertainty is not restricted to "knowledge deficit‟ but encompasses the scientific uncertainties inherent within the technology, and is framed by the social and cultural values of those whose views are considered. This thesis uniquely targeted diverse groups and employed a combination of different methods from a variety of disciplines. By doing this the study has increased understanding of the views of two groups (campaigners and farmers) who are crucial to the uptake of the technology, and who are seldom researched in the area of attitudes to GM technologies. The diversity of groups, methods and disciplines brought together in this thesis is important because the issue of GM has proved to be complex and far-reaching, and previous discussions of risk perceptions have been complex and disjointed. All groups investigated here are stakeholders in the process, and as such their views and concerns relating to risk perceptions of GM technologies ought to be taken into consideration.

Cultural impacts on public perceptions of agricultural biotechnology: comparison between South Korea and the United States

Nader, Richard Harrison 25 April 2007 (has links)
According to Millar (1996), the gulf between science and society is growing. Technologies are tools cultures develop to solve society's problems. The rapid dispersion of science and technology across cultural borders through trade, technology transfer and exchange, increasingly requires people in different cultures to make choices about accepting or rejecting artifacts of science and technology such as genetically modified (GM) foods, which originate primarily from the United States. These issues challenge policy makers and scientists to account for the affects of different cultural perspectives on controversial scientific issues. Given the controversy across cultures over acceptance or rejection of genetically modified (GM) foods, GM foods are an excellent example with which to begin to reveal how culture impacts public perceptions of the risk and benefits of science and technology in different societies. This research will: 1. Define public awareness and understanding of science, specifically GM foods; 2. Examine culture's impact on knowledge, including different cultural approaches to research; and 3. Compare recent findings of a bi-national public opinion survey on GM comparing in South Korea and the United States. The proposed research outlines two research questions: 1) How and in what ways do South Koreans and Americans differ in their opinions about GMOs? This question is important for gathering current points of contrast about how the two cultures may differ; and 2) What role does culture play on opinion formation about GM foods? Through grounded theory, the researcher will investigate how cultural differences help explain opinion on public perceptions of GM foods. Is it possible to identify common cultural factors that impact public perceptions of GM foods between South Koreans and Americans? The study will utilize both qualitative and quantitative methodologies. Higher education is a major producer of new science and technology. The study is significant for higher education administrators who must understand cultural factors impacting science internationally and globalization of the academic enterprise.

Democratizing agricultural planning in New Mexico : a participatory model

Jaramillo, Catherine 04 December 2013 (has links)
Rural areas of New Mexico still exhibit post-colonial political patterns. In terms of its agricultural profile, subsistence farming has only recently (in the past generation) begun to give way to highly specialized, big-business farming interests. Older Hispanic and Pueblo communities struggle to maintain their farming traditions in the face of external economic factors. Now, with the increasing use of genetically-modified seeds on major farm operations and the ongoing development of a transgenic chile seed, a heritage crop, these populations are grappling with intellectual property issues and ecological implications that technological manipulation of native seeds bring. Other growers across the state also have serious concerns about their ability to grow crops from non-genetically modified seeds, as consumers have shown a preference for organic, non-genetically modified foods. Using the guiding analytical tools of Latour and Callon's Actor Network Theory (ANT), I assess the dynamics of power and influence among all agricultural stakeholders to find how a network of disparate elements can achieve “compromise among materially diverse elements” (Rutland and Aylett 2008). This work outlines a framework based on deliberative democratic principles to begin a participatory process that builds upon the disconnected agricultural network of New Mexico. A deliberative process enfranchises previously neglected stakeholders to develop an agricultural policy that deals with genetically engineered crops in a way that reflects the values and goals of the public. / text

Tutela de los derechos del consumidor a la información y a la salud ante el consumo de productos que contienen o son elaborados con organismo vivos modificados (OVM) o transgénicos

Santillana-Chiong, Claudia-Mariana January 2015 (has links)
La investigación es relevante ya que la gran rapidez en la producción y el consumo de productos OVM, hace que sea necesaria la realización de un estudio adecuado sobre la inadecuada regulación de estos productos en relación al derecho a la información y a la salud del consumidor. Así entonces, la investigación busca analizar sobre todo las implicancias de los OVM en los derechos del consumidor a la información y a la salud, teniendo en cuenta que, los OVM que más se comercializan, comprenden el grupo de alimentos más utilizados por los consumidores como el maíz, la soja, el trigo y el arroz, entre otro más. De modo que, la adopción de garantías de tutela para la gran cantidad de consumidores del mercado peruano es una situación de urgente y necesaria atención. Esta característica de estos productos, es decir su carácter de constituir productos de comercio masivo, hace necesario desarrollar un trabajo mediante el cual se pueda determinar que existen deficiencias en la protección de los derechos a la información y a la salud de los consumidores respecto a los OVM. / Tesis

Fantastiskt eller vidrigt? : Uppfattningar om genmodifierad mat

Asplund, Therese January 2008 (has links)
Med genteknik är det möjligt att ändra gensammansättningen i våra livsmedel och applikationen har väckt stort intresse, inte minst bland allmänheten. Genmodifierade (GM) livsmedel har varit föremål för diskussion sedan 1970-talet. Syftet med denna uppsats är att studera olika uppfattningar och representationer om genmodifierade livsmedel. Enligt teorin om sociala representationer har representationer dubbla funktioner. Den ena är att konventionalisera objekt och den andra innebär att representationerna intar en förutbestämd form. För att analysera uppfattningar och representationer har jag använt mig av en tematisk innehållsanalys samt en analys av kommunikativa strategier av samtal i fyra fokusgrupper. Analysen av fokusgruppsdatan visar att diskussionerna cirkulerar kring tre teman: risker, möjligheter och mervärden med genmodifierade livsmedel. De risker som associeras med GM livsmedel diskuteras främst utifrån begreppsparet naturligt/antropogent och utgår ofta från ett grundläggande antagande om att naturen har ett positivt värde. De möjligheter som associeras med GM livsmedel diskuteras utifrån begreppsparet Nord/Syd och utgår ofta från antagandet att GM livsmedel först och främst gör nytta i utvecklingsländer. Antagandet om naturens positiva värde samt uppfattningen om GM livsmedlens frånvaro av fördelar för konsumenter i industrialiserade länder resulterar i att deltagarna inte ser några eller få konsumentfördelar med GM livsmedel. Representationerna kring GM livsmedel kan genom ett gemensamt meningsskapande ses både ha en konventionaliserande funktion där GM livsmedel förankras och förstås samt en preskriptiv funktion där representationerna leder till ett visst sätt att tänka.
