Ecological Monitoring Of Genetically Modified Crops

Proponents of agricultural biotechnology believe that genetically modified (GM) crops have the potential to provide great ecological benefits, such as reduced pesticide and land use, as well as agricultural benefits. However, given the rapid emergence of commercial GM crops and the likely increase in their use, many groups have raised concerns about the potential unintended, adverse ecological effects of these crops. Some ecological concerns are enhanced development of pest resistance, crosspollination with wild relatives, and reductions in beneficial insects or birds. Ecological Monitoring of Genetically Modified Crops considers the latest in monitoring methods and technologies and to asks-What are the challenges associated with monitoring for ecological effects of GM crops? Is ongoing ecological monitoring of GM crops a useful and informative activity? If so, how should scientifically rigorous monitoring be carried out in the variety of ecological settings in which GM crops are grown?

There is an urgent need for guidelines for monitoring of genetically modified higher plants, GMHP. Biotech crops are now cultivated in large scale in North America and elsewhere. In Europe, new genetically modified (GM) products will probably be placed on the market soon and made available of any negative ef for cultivation in the field. Monitoring and surveillance programs for detection fects to the environment must be designed and ready when these crops are released. This also corre sponds to the current intentions made by the European Commission to include monitoring in current biotechnology regulation. Monitoring of changes in biological systems is different from other types of environmental monitoring, such as monitoring fate of chemical pollutants, by focusing primarily on organism survival and organism interactions instead of physical and chemical parameters. The difficulties involved in monitoring biological systems are great, due to the complex interactions between organisms and the variability in responses. Problems concerning spatial and temporal pa rameter variation increase the difficulties, but may be remedied somewhat by the use of "baselines". These and many other questions are discussed in the present book with the aim of presenting practi cal solutions to the needs of GMHP monitoring. A project was initiated in 1998 to produce a book with guidelines for monitoring and surveillance of GMHP. In two earlier books, compilations of current test methods for risk assessment of GMHP were presented (Kjellsson & Simonsen 1994, Kjellsson et al. 1997).

The Food and Agriculture Organization (FAO) hosted an Expert Consultation on "Genetically Modified Organisms in Crop Production and Their Effects on the Environment: Methodologies for Monitoring and the Way Ahead" from 18 to 20 January in Rome. The main objective of the consultation was to review the scientific basis for, and procedures to establish, effective post-release monitoring of genetically modified (GM) crops and develop guidelines to strengthen member countries' capacities to design and carry out monitoring programmes. The consultation was a follow-up to the earlier FAO Expert Consultation on "Environmental Effects of Genetically Modified Crops", which had recommended the environmental effects of GM crops be assessed on a case-by-case basis and emphasized the need to monitor possible medium- to long-term environmental impacts. The main outputs of the meeting were: a review of the scientific criteria and procedures; strategies that could form the basis of efficient monitoring programmes; recommendations for both scientists managing the monitoring process and policy makers.

This book covers a broad spectrum of topics related to GMOs and allied new gene-based technologies, biodiversity, and ecosystem processes, bringing together the contributions of researchers and regulators from around the world. The aim is to offer a clear view of the benefits and effects of genetically modified crops, insects, and other animals on the soil microbiome and ecological processes. Contributors examine issues related to the development of risk assessment procedures and regulations designed to maximize benefits while minimizing risks. Beyond the scientific challenges of GMOs, the book explores the broad and contentious terrain of ethical considerations. The contributors discuss such questions as the unintended, possibly unforeseen, consequences of releasing GMOs into ecosystems, and the likelihood that the full effects of GMOs could take years, even decades, of close monitoring to become evident. The importance of developing a precautionary approach is stressed. The final chapter describes the critical issues of governance and regulation of new and emerging gene-based technologies, as nations grapple with the consequences of adopting the Cartagena Protocol on Biosafety (CPB). The volume includes an extensive Annex which outlines legal perspectives on the state of GMO governance around the world, with more than 20 examples from nations in Africa, South and Central America, Asia, Australasia, and Europe.

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.
