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 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.

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.

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.

This book includes 6 chapters examining the relevance of transgenic crops in food production, prices and the environment. It initially describes the historical evolution of biotechnology and defines key terms, before moving on to explore transgenic technology and food regime concepts. It analyses genetically modified organism (GMO) policy as part of overall agrarian policy, considering neoregulation in the USA, the EU, Brazil, Russia, China, India, South Africa and Serbia, as well as discussing agricultural performance, support and trade relations. The effect of transgenic food production on world food prices is also examined, along with food security at global and regional levels, and the links between GMOs and world hunger. The environmental implications of transgenic technology are considered through analysis of pesticide and fertilizer usage and efficiency, and pesticide consumption in GMO and non-GMO producing countries. Finally, the book considers the entry of transgenic ingredients into the food chain and lists GMOs approved for use in foods and products contaminated with unapproved GMOs. The key features of this book include: a detailed analysis of economic data; a comparison of international trends, including BRICS countries (Brazil, Russia, India, China and South Africa) and Serbia; evaluation of environmental and food security implications; and glossary of important terms. This book is intended for a wide range of professionals and researchers whose interests relate to all aspects of the global food system, including policy makers, policy advisers and analysts, NGOs, students and other interest groups.

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.

Dealing with the challenges presented by climate change or rapid urban development require cooperation and expertise from engineering, social and natural sciences. Earth systems engineering is an emerging area of multidisclinary study that takes a holistic view of natural and human system interactions to better understand complex systems. It seeks to develop methods and tools that enable technically sound and ethically wise decisions. Engineering and Environmental Challenges presents the proceedings of a National Academy of Engineering public symposium on Earth systems engineering.
