The environment is a complex and dynamic system, encompassing both nature and built elements, incorporating people as its key actors. Environmental protection is a science- and engineering-based management practice. However, even current best-management practices are insufficient to achieve the complex and challenging goals of environmental protection and land use. This book presents the main outcomes of the MOKKA project. The actual methods and technologies developed within the MOKKA project include new tools for risk management, risk assessment and risk reduction. The overview provided in this book comprises a broad range of scientific summaries and specific methodological issues, which will contribute to the development of environmental science, technology and management, and establishes a comprehensive approach to environmental problems of our planet. This book will be of interest to environmental scientists in academia, research institutes, industry and the government.
