Methods for Risk Assessment of Transgenic Plants


Book Description

The Berne Symposium invited leading scientists of risk assessment research with transgenic crops on an international level in order to enhance the discussion regulators and members of the biotech industry. The goal was to determine the status quo and also to make progress in times of a first global spread of transgenes in agrosystems about risk assessment. The dialogue between scientists, regulators and industry representatives also revealed some lacunes of risk assessment research, which will have to be filled in the future: We still lack longterm experience, for which we will have to collect data with scientific precision. The symposium concluded asking for a risk-oriented longterm monitoring system based on critical science and hard data. This volume presents the discussion sessions as well as the scientific contributions and thus mirrors the risk assessment debate, based not on exaggerated negative scenarios but on critical science and hard data.




The Pan-European Ecological Network--taking Stock


Book Description

The pace of biodiversity decline is quickening worldwide. Habitat break-up, pollution, over-use of natural areas and the creation of artificial landscapes increase the rate of erosion, while reducing species' opportunity for migration, dispersion and exchange. In 1995, when the European Ministers of the Environment met in Sofia, they launched the Pan-European Biological and Landscape Diversity Strategy, so as to strengthen environment and biodiversity conservation policies. The setting up of the Pan-European Ecological Network covering Eurasia was one of the key steps taken under the Strategy. Work has continued on this project, and it is now based on the numerous national, regional and transregional ecological networks being set up throughout Europe.In Kiev, in 2003, the Ministers and heads of delegation noted these positive developments, expressed firm support for the creation of the Pan-European Ecological Network and asked for its constituent parts to be identified and mapped on a pan-European scale.This book looks at the implementation of this Network in the 55 states concerned. It has been written by a team comprising, under the aegis of the Council of Europe, numerous government experts and specialists dealing with the issue of ecological networks. It is intended to reassure Ministers, policy-makers and scientists that they made the right decision in supporting the creation of the Pan-European Ecological Network with a view to (re-)creating a true green infrastructure for Europe.




Corridors for Birds Within a Pan-European Ecological Network


Book Description

This report considers the signifiance of corridors for high priority bird species within the development of Pan-European Ecological Network. This involves a brief review of existing research and policy, the testing of recent corridor ideas and typologies, the application of these ideas to fifteen birds "species of European Conservation Concern" and discussion of the next steps for research and policy development.




General Guidelines for the Development of the Pan-European Ecological Network


Book Description

The Pan-European Biological and Landscape Diversity Strategy, which was endorsed by ministers from 54 countries in the UN-ECE region on 25 October 1995, provides for the establishment by 2005 of the Pan-European Ecological Network. These Guidelines provide a reference document for all those involved in establishing and managing the network. The document aims to provide a coherent framework for guiding an array of co-operative, decentralised measures which aim to ensure the conservation and sustainable use of the ecosystems, habitats, species and landscapes of European importance.




Monitoring and surveillance of genetically modified higher plants


Book Description

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).







Methods for Risk Assessment of Transgenic Plants


Book Description

The present work is a continuation of the work initiated in Autumn 1991, which resulted in the book, published by Birkhauser Verlag in 1994, entitled: Methods for Risk Assessment of Transgenic Plants. I. Competition, Establishment and Ecosystem Effects. Already when the work on volume 1 started, it was obvious to the authors, that not only the physical establishment of a transgenic plant outside the cultivated area was important for risk assessment, but also the possible gene-transfer from transgenic plants to other plants had to be considered. It was then decided to write a second volume on test methods, as a complement to the first, covering the main topics: Pollination, gene-transfer and population impacts. The main user groups for this volume are scientists and students working with plant population genetics and risk assessment and administrators with responsibility for legislation of transgenic plants. In order to cover such a broad range of topics, specialist knowledge was required. Therefore, colleagues in Denmark and Switzerland, working in these fields in relation to the concerns of using transgenic plants, were asked to participate. The result was a Danish-Swiss cooperation. A list of contributors to the book and their addresses is shown on p. VII. Financial support, which made the work possible, was given by: The National Environmental Research Institute, Denmark, the Federal Office of Environment, Forest and Landscape, Switzerland, the National Forest and Nature Agency, Denmark, the Danish Environmental Protection Agency and the European Commission, DC XI.




Pan-European Biological and Landscape Diversity Strategy


Book Description

Text drawn up in collaboration with the European Centre for Nature Conservation, Tilburg, the Netherlands, submitted by the Council of Europe at the Ministerial Conference "Environment for Europe" (Sofia, Bulgaria, 23-25 October 1995), and approved by the ministers of the environment of the 55 states present at the conference




Bacillus thuringiensis Biotechnology


Book Description

Bacillus thuringiensis (Bt) has been used as a biopesticide in agriculture, forestry and mosquito control because of its advantages of specific toxicity against target insects, lack of polluting residues and safety to non-target organisms. The insecticidal properties of this bacterium are due to insecticidal proteins produced during sporulation. Despite these ecological benefits, the use of Bt biopesticides has lagged behind the synthetic chemicals. Genetic improvement of Bt natural strains, in particular Bt recombination, offers a promising means of improving efficacy and cost-effectiveness of Bt-based bioinsecticide products to develop new biotechnological applications. On the other hand, the different Bacillus species have important biotechnological applications; one of them is carried out by producing secondary metabolites, which are the study object of natural product chemistry. The amazing structural variability of these compounds has attracted the curiosity of chemists and the biological activities possessed by natural products have inspired the pharmaceutical industry to search for lead structures in microbial extracts. Screening of microbial extracts reveals the large structural diversity of natural compounds with broad biological activities, such as antimicrobial, antiviral, immunosuppressive, and antitumor activities that enable the bacterium to survive in its natural environment. These findings widen the target range of Bacillus spp., in special B. thuringiensis, besides insecticidal activity and help people to better understand its role in soil ecosystem.
