  • Can genetic engineering help quench crops’ thirst?

    Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close ...

  • The complex nature of GMOs calls for a new conversation

    An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many ...

  • Indian government still ‘flip flopping’ on GM trials

    In August, India’s ruling nationalist Bharatiya Janata Party (BJP) stopped its legislators from accepting Monsanto sponsorship to attend a farm exhibition in the US state of Iowa. On the surface this might seem strange: attending the Farm Progress Show should be innocuous, as Monsanto routinely takes farmers, industry experts, media and MPs from various countries to visit the show and ...

  • The problems with the arguments against GM crops

    New evidence shows that arguments against GM crops are unfounded, says Margaret Karembu. The year 2013 marked the 18th consecutive year of commercial cultivation of genetically modified organisms (GMOs) or now commonly referred to as biotech crops. And in just under two decades, the volume of ...

  • Risks of neonicotinoid insecticides to honeybees

    The European honeybee, Apis mellifera, is an important pollinator of agricultural crops. Since 2006, when unexpectedly high colony losses were first reported, articles have proliferated in the popular press suggesting a range of possible causes and raising alarm over the general decline of bees. Suggested causes include pesticides, genetically modified crops, habitat fragmentation, and ...

  • The socio–economic impacts of currently commercialised genetically engineered crops

    A substantial and growing body of literature now exists on the socio–economic impacts of genetically engineered (GE) crops. While the bulk of literature has focused on the primary impacts of commercialised GE technology, in terms of changes in yields, costs and profitability, researchers have increasingly addressed a range of additional questions such as the distribution of impacts across groups, ...

  • How negative product attributes alter consumer perceptions of folate biofortified rice in a high risk region of China

    Folate biofortified rice is recently developed as a future strategy to reduce folate deficiency, particularly in poor, rural high risk regions, like Shanxi Province. Although 62% of rice consumers in this Chinese region are likely to accept this GM product, biofortification could negatively change product attributes, which may hamper acceptance. The results of this ex–ante evaluation show ...

  • Accumulation and translocation of 198Hg in four crop species

    The uptake and transport of mercury (Hg) through vegetation play an important role in the biogeochemical cycling of Hg. However, quantitative information regarding Hg translocation in plants is poorly understood. In this study, Hg uptake, accumulation and translocation in four corps rice (Oryza.sativa L.), wheat (Triticum L.), corn (Zea mays L.) and oilseed rape (Brassica campestris L.) grown ...

  • Asia–Pacific Analysis: Plan for growth in biotech crops

    South-East Asian nations should follow the Philippines down the path to biotech crops for food security, argues Crispin Maslog. Since biotechnology-derived crops were introduced in 1996, they have been adopted at an unprecedented rate, according to the 2011 annual report of the International Service for the Acquisition of Agri-biotech Applications (ISAAA) released earlier this year. ...

  • Molecular genetic linkage map for allotetraploid colonial bentgrass

    Interspecific hybridization is a widely used approach to improve crop species. We are pursuing the possibility of using interspecific hybridization between the turfgrass species colonial bentgrass (Agrostis capillaris L.) and creeping bentgrass (A. stolonifera L.) for the improvement of resistance to the fungal disease dollar spot (Sclerotinia homoeocarpa F.T. Bennett) in creeping bentgrass. From ...

  • Could food shortages bring down civilization?

    One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...

  • Property claims in genetically and non-genetically modified crops: intellectual property rights vs. brand property rights in postindustrial knowledge societies

    Conceptualising the ongoing conflict over genetically modified vs. non-genetically modified crops in the frame of property rights, one can see that economic valorisation dynamics and aspirations are working on both sides, within two differently evolving agri-food paradigms, with biotechnology companies propagating intellectual property rights on seeds and crops within a productivist strategy, and ...

  • Social resistance to biotechnology: attempts to create a Genetically Modified-free territory in Brazil

    This paper looks at the attempt to create a territory free of transgenic crops in the state of Rio Grande do Sul (RS) Although the state government had legal grounds under federal law and court decisions that banned these crops in Brazil, resistance by groups representing local farmers managed to disseminate the planting of transgenic soybeans in the state. The reasons for the government's ...

  • A differentiated account of the role of trust in consumers' acceptance of genetically modified foods in Germany

    This paper proposes a sequential model to contrast the causal chain and associationist models on the role of trust in GM food acceptance. Data from 60 laddering interviews suggest the role of trust in evaluating the perceived consequences of GM food production and consumption is small and that the link between risk and trust is rather weak, too. Lending further support to the relevancy of the ...

  • The economic impacts of second generation Bt cotton in West Africa: empirical evidence from Burkina Faso

    West Africa has been slow in adopting agricultural biotechnology. The most progressive stance has been taken by Burkina Faso, which began field testing Bt cotton in 2003. This paper reports the first three years of Bt cotton field trials, which found that Bt cotton increased cotton yields by an average of 20% and reduced insecticide applications by two-thirds. While the technical success of Bt ...
