Many international forums have identified the need for comprehensive, scientific methods for the pre-release testing and post-release monitoring of transgenic plants to ensure their environmental safety and sustainable use. In response to this requirement, the International Project on GMO Environmental Risk Assessment Methodologies develops biosafety testing methodologies in support of risk assessment for transgenic plants. This second volume focuses on transgenic cotton that is resistant to insect pests in Brazil, and addresses both environmental and agricultural impacts. It draws out a general risk assessment concept and demonstrates the need for case-by-case analysis. This book makes a significant contribution to this field and will interest readers in crop science, biotechnology, ecology, pest management and policy analysis, with a focus on the needs of developing countries.
