Environmental hazards do not respect international boundaries. In this volume, distinguished international researchers make a significant contribution to the understanding and management of the transboundary risks involved.Numerous case studies of transboundary environmental risks are analyzed, including BSE and Himalayan water projects.General issues raised by the cases are considered, including: How are transboundary risks identified and assessed? How are they communicated within and between countries? What forms of risk management are appropriate?Key issues concerning public participation and the political significance of transboundary risks emerge, from which useful practical lessons on the management of risk are drawn.The volume provides valuable evidence and analysis for those working on international environmental issues and all aspects of risk management.
