Monsanto’s Biotechnology Politics: Discourses of Legitimation

Since the first product became commercially available in 1995, biotechnology has become the fastest growing crop technology, dominating large shares of the global agricultural market. The development of biotechnology, however, has given rise to questions regarding human and ecological safety, culminating in local and global political battles. While researchers interested in biotech politics have focused on areas such as media framing, social movements, and campaign work, less attention has been paid to how the industry has historically promoted and legitimized this swift proliferation. In this study, we conduct a discourse analysis of documents available on live and archived websites to discern the legitimation strategies employed by one important corporate actor, Monsanto. Findings show that for nearly two decades, Monsanto consistently employed discursive resources that concealed details about actors and action, reflected trends among experts in global sustainability discourse, and reshaped narratives to promote itself, products, and biotechnology in general.     

A proposed impact assessment method for genetically modified plants (AS-GMP Method)

An essential step in the development of products based on biotechnology is an assessment of their potential economic impacts and safety, including an evaluation of the potential impact of transgenic crops and practices related to their cultivation on the environment and human or animal health. The purpose of this paper is to provide an assessment method to evaluate the impact of biotechnologies that uses quantifiable parameters and allows a comparative analysis between conventional technology and technologies using GMOs. This paper introduces a method to perform an impact analysis associated with the commercial release and use of genetically modified plants, the Assessment System GMP Method. The assessment is performed through indicators that are arranged according to their dimension criterion likewise: environmental, economic, social, capability and institutional approach. To perform an accurate evaluation of the GMP specific indicators related to genetic modification are grouped in common fields: genetic insert features, GM plant features, gene flow, food/feed field, introduction of the GMP, unexpected occurrences and specific indicators. The novelty is the possibility to include specific parameters to the biotechnology under assessment. In this case by case analysis the factors of moderation and the indexes are parameterized to perform an available assessment.     

Chemical synthesis of 6-pentyl-2H-pyran-2-one: a natural antifungal biosynthesized by Trichoderma spp.

Trichoderma spp. biosynthesize 6-pentyl-2H-pyran-2-one (6-PP), a natural antifungal pyrone which could be used as biological control agent (BCA). Unfortunately, biotechnical processes are limited by inhibition of biomass at high concentration of 6-PP. We report herein a new easy synthesis of this natural pyrone, using readily available starting materials. This synthesis, compatible with a large production scale, permit to obtain overweight amounts of 6-PP that in biotechnological routes.     

Exploring the Links Between Science, Risk, Uncertainty, and Ethics in Regulatory Controversies About Genetically Modified Crops

Just as a stream of genetically modifiedcrops looked set to be approved for commercialproduction in the European Union, the approvalprocedure appears to have become bogged down onceagain by disagreements among and within member states.Old controversies have resurfaced in new forms. Theintractability of the issues suggests that theregulatory procedure has had too narrow a focus,leaving outside its boundary many of the morefundamental aspects that cause people in the EuropeanUnion most concern. Regulators have come underconsiderable pressure to ensure their risk assessmentdecisions are soundly science-based. Ethical issueshave been deemed to lie beyond the scope of theregulatory procedure, as a matter to be consideredseparately by professional ethicists. Yet it has beensuggested that all environmental controversies at rootinvolve disputes about fundamental ethical principles.This paper examines how the ethical issues arecurrently suppressed or sidelined. It discusses how anappreciation of systems thinking and a check on thevalues that underpin decisions, using boundary testingquestions, might contribute to a more constructiveregulatory dialogue, with ethical issues considered asintegral in a way that takes better account ofpeople's concerns.     

Vegetarian Meat: Could Technology Save Animals and Satisfy Meat Eaters?

Between people who unabashedly support eating meat and those who adopt moral vegetarianism, lie a number of people who are uncomfortably carnivorous and vaguely wish they could be vegetarians. Opposing animal suffering in principle, they can ignore it in practice, relying on the visual disconnect between supermarket meat and slaughterhouse practices not to trigger their moral emotions. But what if we could have the best of both worlds in reality—eat meat and not harm animals? The nascent biotechnology of tissue culture, originally researched for medical applications, holds out just such a promise. Meat could be grown in vitro without killing animals. In fact, this technology may not just be an intriguing option, but might be our moral obligation to develop.     

The century of biology: three views

The claim that the twenty-first century will be the century of biology could turn out to be true in three very different ways. One view is that developments in biotechnology will help to treat diseases and improve life. Another view is that changes in the biosphere will lead to extreme scarcity and endanger billions of humans. A third view is that biotechnology and climate change will further bifurcate the world into people with good health prospects and people with poor health prospects. I describe these views and show how they involve different accounts of the ethical issues that we will face and the ethical virtues that we will need to cultivate.

Regulatory Oversight of Genetically Engineered Microorganisms: Has Regulation Inhibited Innovation?

/ Using detailed interviews with company representatives and researchers in the field, this paper examines the factors that might account for the slow pace of development of genetically engineered microorganisms (GEMs) intended for environmental release. We specifically analyzed the role of the regulatory system in shaping innovation. We identified at least two cases where industry decided to discontinue the development of a genetically engineered microbial product because of concerns over regulatory oversight. However, most often industry decisions to continue or halt development of GEMs were based on an evaluation of the particular product's efficacy and potential for profitability. Thus the inability of GEMs to perform up to expectations in the field, rather than the regulatory constraints, appears to be the factor responsible for the slow pace of development.
