Genetically Engineered Crops


Book Description

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.




GM Crops and the Global Divide


Book Description

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:The Life and Work of a Scientist in GM Crops, 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.

Environmental Impact of Genetically Modified Crops


Book Description

The genetic modification of crops continues to be the subject of intense debate, and opinions are often strongly polarised. Environmental Impact of Genetically Modified Crops addresses the major concerns of scientists, policy makers, environmental lobby groups and the general public regarding this controversial issue, from an editorially neutral standpoint. While the main focus is on environmental impact, food safety issues, for both humans and animals are also considered. The book concludes with a discussion on the future of agricultural biotechnology in the context of sustainability, natural resource management and future global population and food supply.




Genetically Modified Food Sources


Book Description

Genetically Modified Food Sources reports detailed results of studies on the medical and biological safety of 14 species of genetically modified plant-derived organisms (GMOs). The authors focus on issues in GMO production and world output, specifically the basic legislative regulations of modern biotechnology in the Russian Federation. Also covered are international approaches to the medical and biological assessment of safety and control of the food produced from genetically modified organisms. A special chapter is devoted to the problem of informational coverage of novel biological technologies.Previously available only in a 2007 Russian-language edition published by the Russian Academy of Medical Sciences, this English translation has been completely revised and updated to include the latest developments in regulations and human and animal safety assessment practices.The book is addressed to a wide community of specialists working in the fields of food science, plant genetics, and food safety as well as medicine and biology. Students and postgraduates focusing on the problems of modern biotechnology and biological safety will find it a valuable guide to these topics. - Specific assessments of 14 species of genetically modified plant-derived organisms used for food supply - Addresses the safety assessment requirements to ensure consumer health - International coverage provides comparative insights into regulation development and application




Transgenic Crops of the World


Book Description

Since the first transgenic plants were produced back in the early 1980s, there have been substantial developments towards the genetic engineering of most crops of our world. Initial studies using isolated plant cells and removing their cell walls to form protoplasts, offered the possibility of transferring genetic material by Agrobacterium-mediated gene transfer, chemical agents or electrical charges. However, in those cases were isolated protoplasts could be transformed, often, a shoot regeneration system was not available to induce the production of transgenic plants and any such regenerated plants were subject to mutation or chromosomal of cultured plant organs, such as leaf abnormalities. By the mid-1980s, the use disks, offered the convenience of combining gene transfer, plant regeneration and selection of transformants in a single system. This approach, enabled the production of stable, phenotypically-normal, transgenic potato and tomato plants in culture. By the late 1980s, the use of biolistics offered a means of inserting foreign genes into plant cells which where inaccessible to Agrobacterium infection. Even today, this technology is now standard practice for the production of some transgenic plants.




Seeds of Contention


Book Description

In recent years the media have reported on the increasing use of genetically modified crops in agriculture. This text focuses attention on the less discussed issues of the potential benefits of genetically modified crops for developing countries.




Integration of Insect-Resistant Genetically Modified Crops within IPM Programs


Book Description

Insect pests remain one of the main constraints to food and fiber production worldwide despite farmers deploying a range of techniques to protect their crops. Modern pest control is guided by the principles of integrated pest management (IPM) with pest resistant germplasm being an important part of the foundation. Since 1996, when the first genetically modified (GM) insect-resistant maize variety was commercialized in the USA, the area planted to insect-resistant GM varieties has grown dramatically, representing the fastest adoption rate of any agricultural technology in human history. The goal of our book is to provide an overview on the role insect-resistant GM plants play in different crop systems worldwide. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production.




The Future of Genetically Modified Crops


Book Description

The world is now on the cusp of a new agricultural revolution, the so-called Gene Revolution, in which genetically modified (GM) crops are tailored to address chronic agricultural problems in certain regions of the world. This monograph report investigates the circumstances and processes that can induce and sustain this new agricultural revolution. The authors compare the Green Revolution of the 20th century with the GM crop movement to assess the agricultural, technological, sociological, and political differences between the two movements.
