Transgenic Crops

Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Attitudes to GM crops continue to generate tension, even though they have been grown commercially for over 20 years. Negative sentiment towards their development limits their adoption in Western countries, despite there being no evidence of harm to human health. These unfounded concerns about genetically modified crops have also inhibited uptake in many countries throughout Africa and Asia, having a major impact on agricultural productivity and preventing the widespread cultivation of potentially life-saving crops. GM Crops and the Global Divide traces the historical importance that European attitudes to past colonial influences, aid, trade and educational involvement have had on African leaders and their people. The detrimental impact that these attitudes have on agricultural productivity and food security continues to be of growing importance, especially in light of climate change, drought and the potential rise in sea levels – the effects of which could be mitigated by the cultivation of GM and gene-edited crops. Following on from her previous books Genes for Africa, GM Crops: The Impact and the Potential and Food for Africa, Jennifer Thomson unravels the reasons behind these negative attitudes towards GM crop production. By addressing the detrimental effects that anti-GM opinions have on nutrition security in developing countries and providing a clear account of the science to counter these attitudes, she hopes to highlight and ultimately bridge this global divide.

Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.

As development donors invest hundreds of millions of dollars into improved crops designed to alleviate poverty and hunger, Africa has emerged as the final frontier in the global debate over agricultural biotechnology. The first data-driven assessment of the ecological, social, and political factors that shape our understanding of genetic modification, Africa's Gene Revolution surveys twenty years of efforts to use genomics-based breeding to enhance yields and livelihoods for African farmers. Matthew Schnurr considers the full range of biotechnologies currently in commercial use and those in development - including hybrids, marker-assisted breeding, tissue culture, and genetic engineering. Drawing on interviews with biotechnology experts alongside research conducted with more than two hundred farmers across eastern, western, and southern Africa, Schnurr reveals a profound incongruity between the optimistic rhetoric that accompanies genetic modification technology and the realities of the smallholder farmers who are its intended beneficiaries. Through the lens of political ecology, this book demonstrates that the current emphasis on improved seeds discounts the geographic, social, ecological, and economic contexts in which the producers of these crops operate. Bringing the voices of farmers to the foreground of this polarizing debate, Africa's Gene Revolution contends that meaningful change will come from a reconfiguration not only of the plant's genome, but of the entire agricultural system.

Transgenic crops offer the promise of increased agricultural productivity and better quality foods. But they also raise the specter of harmful environmental effects. In this new book, a panel of experts examines: • Similarities and differences between crops developed by conventional and transgenic methods • Potential for commercialized transgenic crops to change both agricultural and nonagricultural landscapes • How well the U.S. government is regulating transgenic crops to avoid any negative effects. Environmental Effects of Transgenic Plants provides a wealth of information about transgenic processes, previous experience with the introduction of novel crops, principles of risk assessment and management, the science behind current regulatory schemes, issues in monitoring transgenic products already on the market, and more. The book discusses public involvementâ€"and public confidenceâ€"in biotechnology regulation. And it looks to the future, exploring the potential of genetic engineering and the prospects for environmental effects.

As the world debates the risks and benefits of plant biotechnology, the proportion of the global area of transgenic field crops has increased every year, and the safety and value continues to be demonstrated. Yet, despite the success of transgenic field crops, the commercialization of transgenic horticultural crops (vegetables, fruits, nuts, and or
