12 pages, To date, there has been an increase in genome modification biotechnologies that improve production and food security but the process has not been accompanied by the delivery of information about them intended for citizens. This is essential considering that to achieve better health, food security and sustainability these biotechnologies need to be incorporated into production systems. This study aimed to explore perceptions and attitudes of Chilean citizens towards the use of genome modifications with an emphasis on transgenes and genome editing (CRISPR). An electronic questionnaire was applied, and afterwards the results were analysed through descriptive statistics, GLM, Spearman’s correlation and Wilcoxon Signed Rank test. A total of 702 questionnaires were analysed. High awareness of concepts such as transgenic and cloning was reported with CRISPR being the least known term. Most respondents perceived negative effects on health regarding the consumption of genetically modified products, with women having a significantly more negative attitude. Still, a high willingness to use CRISPR for improving animal and human health was reported. When comparing vegetable and animal products that underwent CRISPR or transgenes, the willingness to consume these products was higher for vegetables. The results show that changes in perception can be achieved after providing the definition of CRISPR and transgenic, therefore, consumer education seems to be essential. Science communication focused on making information about genome modification biotechnologies available to citizens could promote more positive attitudes and perceptions and facilitate their future implementation in the country.
10 pages, Biotechnology use in food production has been a polarizing topic that has encountered resistance from some consumers. The discovery of genome editing biotechnology, in which no foreign genetic material is introduced into the host organism while making accurate and efficient changes in genomes, has the potential to revolutionize food biotechnology in a more socially acceptable and less polarizing fashion. The success and adoption of gene-edited foods, however, ultimately depends on consumer acceptance. This study reports the results of a geographically disperse Chinese consumer acceptance study (n = 835) in which individuals evaluated rice and pork products that were bio-engineered to address two significant hazards that have recently garnered international attention: cadmium contamination in rice and African swine fever. We explore the role that food technology neophobia has on consumer acceptance and assess how information on the differences between transgenic and gene editing technologies affects consumer preferences. While averse to the use of biotechnology in food products, consumers were considerably more accepting of products that have undergone genome editing rather than transgenic modification. We find differential impacts of information provision on preferences between pork and rice products and on preferences for product provenance. Our analysis indicates that a reduction in consumers’ fear of novel food technologies can substantially increase consumer valuation and market acceptance of bioengineered food products and reinforces the need to consider attitudes in measuring acceptance of novel food products.

Notes:
126 pages., ISBN: 9780438013049, Via ProQuest Dissertations and Theses., Genetically modified foods and crops are a topic of heated debate in the United States. As with all issues, messaging has the potential to influence and change an individual’s attitude. Through the lens of social judgment theory, this quasi-experimental study investigated the influence of an evidence-based message on millennial agricultural students’ attitudes towards genetically modified foods and crops, while taking into account participants’ ego-involvements for the issue. Sixty-nine undergraduate students in the College of Agriculture participated in this study – comprised of a pre-test and post-test questionnaire with an evidence-based message intervention between.
The major finding from this study was that for the issue of genetically modified foods, millennial agricultural students’ with high ego-involvement are capable of attitude change and moving their anchor points in the direction of viewing genetically modified foods and crops less favorably than prior to the evidence-based message intervention. This result was unexpected, but important. Another key finding is that the majority of millennial agricultural students reported holding favorable attitudes towards genetically modified foods. In regards to the risks of genetically modified foods, the majority of participants disagreed that there is any risk associated with eating genetically modified foods and were neutral towards any environmental risks of genetically modified crops. This study also investigated the role of ego-involvement and the widths of the latitudes of acceptance, noncommitment, and rejection. While there was a trend for the latitude of acceptance to increase and for the latitude of rejection to decrease for both the high and low ego-involvement groups, these findings were insignificant.
Overall, this study’s findings provides great insight to science communicators who are messaging with the goal of influencing attitude change. Utilizing key elements of science communication including, weight of evidence reporting, weight of experts reporting, reinforcement of self-identity, credibility, valence, and framing theory, it is possible to influence attitude change, at least for millennial agricultural students with high ego-involvement for the issue of genetically modified foods. Future research should expand to include other segments of the population, as well as other science issues.
6 pages., Gene editing (GE) and gene modification (GM) technologies demonstrate noticeable differences. GE technologies introduce changes in DNA, which are intrinsic to the species, while GM technologies incorporate changes from foreign species. The potential benefits of GE have been highlighted in a number of recent scientific studies, pointing to the opportunities that are opening up in addressing the food availability problems as a result of the growing world population. However, the implementation of GE technology in food production would rely on public awareness, acceptance, and attitudes toward genetically modified and genetically edited food products. Based on the Theory of Reasoned Action (TRA), we surveyed Lithuanian consumers, farmers, and producers for their awareness, attitudes, and behavioural intentions towards GM and GE food. The 251 consumers, 50 farmers, and 56 food producers participated in the survey. Consistent across all samples (consumers, farmers, and producers, respectively), GM technology-related products’ self-assed awareness was significantly higher than the level of self-assed awareness of GE products. Awareness of GEO in all samples is relatively low. The level of support for GMO and GEO is also low in all groups of respondents. All groups – consumers, farmers, and producers – are less negative about food produced from GE than from GM raw materials. There was a statistically significantly higher overall likelihood for future use of GEO than the GMO. Producers would be less likely than consumers and farmers to use GMOs in the future. The same inclinations are observed with regard to GEO, with statistically significant differences in the sample of consumers, farmers, and producers.
9 pages, Humans have improved plants for their utility through selective self-pollination, crossing, and progeny selection for >10,000 years, largely based on physical characteristics. Less than 200 years ago, the genetic basis of heritability in selection was revealed, enabling breeders to accelerate genetic gain. Breakthroughs in genomics and molecular markers for the past century have enabled breeders to locate and select genomic regions affecting desirable traits, improving breeding precision. Transgenesis has enabled crop insertion of desirable exogenous genes, enabling de novo functionality. These technologies, along with agronomic practices, have generated more than sixfold yield improvements in crops such as corn in the past century. Gene editing, with its unique ability to precisely edit, change expression, and move genes within a crop's genome, has the potential to be the next breakthrough technology. For this to come to fruition, it is critical to take a holistic view considering perspectives of scientists, farmers, regulators, and consumers.
15 pages, Bioeconomy is deemed to be an ambiguous term with multiple facets: new products from biomass, circular and cascading resource systems, developments of new and more resilient plants, or synthetic biology for molecular biotechnology, to name a few. Accordingly, the term is interpreted just as diversely by involved stakeholders and the broader public. Enabling a clear and constructive dialog on bioeconomy strategies with and among society requires a profound understanding of these perceptions. To address this issue, a representative survey was conducted among the German population in order to scrutinize the general public's understanding of the term bioeconomy, citizens’ knowledge, fears, and expectations, as well as factors explaining their attitudes toward the bioeconomy. Our results indicate that, so far, German citizens are not very familiar with the concept. Its underlying ideas, however, are vastly appreciated. Support for a sustainable bioeconomy is thus strong and connected to high expectations in terms of environmental and economic benefits, which needs to be taken into account both in the implementation and communication of bioeconomy strategies. Support for the bioeconomy is furthermore connected to beliefs that reflect environmental concern and to pro-environmental behavior. While most measures and principles related to the bioeconomy (e.g., the use of biogas, biofuels, renewable materials for everyday products or buildings, or the cascading and circular use of resources) are strongly appreciated, the use of genetic engineering, for example, is opposed, mainly with regard to its applications in agriculture and industry, to a lesser extent in medicine.
18 pages., via online journal, The aim of this paper is to investigate the perceptions of small-scale farmers in Brazil towards genetically modified (GM) crops based on a sample of 15 focus groups involving 111 individuals. The analysis of the corpus shows heterogeneous perceptions regarding these crops, shaped by diverse factors, including economic prospects and concerns with the impact on health and the environment. There are many misgivings about these effects among the farmers, who are keen to receive unbiased information on the topic. These uncertainties affect them more as consumers, as most would prefer eating GM-free food, than as producers, as they consider other aspects, especially economic feasibility, when deciding what to grow. Although most farmers believe they should have a voice in decision-making on agricultural issues, few have made concerted efforts to be heard.

98 pages., ISBN: 9780438072190, Via ProQuest Dissertations and Theses., This study explored how preexisting values influence attitudes about GMOs and if aligning messages about GMOs with these values would lead to a greater chance of central processing, and subsequently, greater alignment with message-congruent attitudes. Utilizing the Elaboration Likelihood Model as a theoretical foundation, an online experiment was used to measure several values of participants, including altruistic, biospheric and egoistic value orientations as well as agricultural identity. Attitude accessibility and pre- and post-opinions were also measured in order to determine how much of an effect the presented stimuli had on the participants. All participants were presented with a stimulus that either aligned or didn’t align with their self-ranked GMO value-argument. It was found that attitude accessibility, agricultural identity and in some cases a biospehric value orientation were the most important predictors for a number of constructs related to GMO attitudes. In addition, agricultural identity did not correlate with any other value orientation, yet was the strongest predictor of many related attitudes. Future research should continue to explore the complexity of values within agricultural communication contexts and expand the understanding of how agricultural identity influences such outcomes.
