Abstract: Genetically modified (GM) food crops are considered to have the potential of providing food security especially in developing countries. Scientists have raised concern over the hazards associated with the consumption of genetically modified organisms (GMOs). One of these hazards, which have great controversy reports, is the possible horizontal gene transfer from GM-food or feed …

Abstract: The International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD) was the biggest review ever of global agriculture. It developed different approaches for alleviating hunger and poverty, focussing on the productivity of small household farms and supporting low-tech and cost-free strategies. Not long before the final IAASTD plenary, the chemical-biotech indus try …

To the editor: A News article in the July issue1 brings up some important questions about our report, Failure to Yield, which analyzes the contribution of genetic engineering to increased food and feed production in the United States, and its potential for contributing to global food security. I would like to clarify some points by …

Abstract: From the countryside to the cubicle, this contribution explores vulnerabilities to genetically modified (GM) contamination of maize landraces in northern Guatemala following the DR-CAFTA (Dominican Republic-Central America-United States Free Trade Agreement). Although some industrial farmers elsewhere in Guatemala might welcome GM seeds, in this lowland refuge zone, transnational agribusiness corporations would largely face a …

Abstract: Advances in genetic modification technology and the production of human-altered genomes have led to an array of genetically modified organisms utilized to address numerous global issues. The human need-based development of these modified organisms often presents unprecedented phenotypes which will interact with the world’s existing biodiversity in unknown ways. One such example is Bt …

Abstract: The arguments presented by Espinoza et al. in their paper “Relationship of genetically modified crops with the environment and health of the Costa Rican human population” published in this journal (Rev. Biol. Trop. 52: 727-732, 2004) are questioned and refuted. The arguments are confronted with evidence offered by scientists and national and international independent …

Abstract: The potential for genetically modified (GM) crops to threaten biodiversity conservation and sustainable agriculture is substantial. Megadiverse countries and centers of origin and/or diversity of crop species are particularly vulnerable regions. The future of sustainable agriculture may be irreversibly jeopardized by contamination of in situ preserved genetic resources threatening a strategic resource for the …

Abstract: The authors discussed the prospects in application of transgenic technologies for commodity production of fish in commercial aquarium, for the use of fish as bioindikator organism with clear determinate pathological symptoms (for instance, for ecological monitoring, valuation of risk, influence of acute exposure of high doses and chronic effect of small doses of chemical …

Abstract: There is intense debate about the role of genetically modified (GM) food crops in combatting low yields and food insecurity amongst smallholders in Africa. Bt maize is still the only commercialised GM food crop in Africa and thus provides an unique opportunity for an empirical evaluation on this matter. South Africa is the only …

Abstract: Genetic modification or GMO is a new technology that assures to give food security to the developing nations. Commercial growth of genetically modified crops has been increasing very rapidly. But some disagreements are also associated of using genetically modified crops. Though GM crops promises to give the food security to developing countries, at the …

Abstract: Objective. To expose the likely impact of genetically modified foods in Collective Feeding. Methods: This was a case study conducted on a steel company (SC) in Rio de Janeiro State. The likely impact recognition began with the preparation of a soy food products’ list. Then, we verified these products’ frequency on the Food and …

Abstract: This paper frames genetically modified organisms (GMOs) as invasive species. This offers a way of considering the reception, diffusion and management of GMOs in the foodscape. “An invasive non-native species is any non-native animal or plant that has the ability to spread causing damage to the environment, the economy, our health and the way …

Abstract: In order to developing a methodology evaluating the alimentary security of transgenic products, it has been done a ninety-days study using thirty-two BALB/c mice aging 6 to 8 weeks, where transgenic with Cry1Ab, an insecticide protein against Lepidoptera bugs was used. The animals were divided in four groups of eight; and received control diet …

Abstract: This article highlights some of the hundreds of cases of genetic contamination that have been registered in different regions of the world by the organizations GeneWatch and Greenpeace International. You will be reading about confirmed cases in Costa Rica of GMO contamination of seeds and foods imported from abroad. There are comments on the …

Abstract: The first of the Millennium Development Goals – halve the proportion of people who suffer from hunger by 2015 – is essential for eradicating poverty, as most of the poor live in rural areas. The role of agriculture is, therefore, key to the fight against poverty.Nevertheless, over the last years rich countries diminished their …

Abstract: This paper challenges the recent hailing of agricultural biotechnology as a panacea for food insecurity and rural poverty in countries of the global South. Based on an empirical investigation of the neoliberal soy regime in Paraguay, I document how the profound transformation of this country’s agricultural mode of production over the past two decades, …
