From the beginning of 21st century, there has been an awareness of
risk in the environment along with a growing concern for the
continuing potential damage caused by hazards. In order to ensure
environmental sustainability, a better understanding of natural
disasters and their impacts is essential. It has been recognized
that a holistic and integrated approach to environmental hazards
needs to be attempted using common methodologies, such as risk
analysis, which involves risk management and risk assessment.
Indeed, risk management means reducing the threats posed by known
hazards, whereas at the same time accepting unmanageable risks and
maximizing any related benefits. The risk management framework
involves evaluating the importance of a risk, either quantitatively
or qualitatively. Risk assessment comprises three steps, namely
risk identification (data base, event monitoring, statistical
inference), risk estimation (magnitude, frequency, economic costs)
and risk evaluation (cost-benefit analysis). Nevertheless, the risk
management framework also includes a fourth step, risk governance,
i.e. the need for a feedback of all the risk assessment
undertakings. There is currently a lack of such feedback which
constitutes a serious deficiency in the reduction of environmental
hazards. This book emphasises methodological approaches and
procedures of the three main components in the study of
environmental hazards, namely forecasting - nowcasting (before),
monitoring (during) and assessment (after), based on geoinformatic
technologies and data and simulation through examples and case
studies. These are considered within the risk management framework
and, in particular, within the three components of risk assessment,
namely risk identification, risk estimation and risk evaluation.
This approach is a contemporary and innovative procedure and
constitutes current research in the field of environmental hazards.
Environmental Hazards Methodologies for Risk Assessment and
Management covers hydrological hazards (floods, droughts, storms,
hail, desertification), biophysical hazards (frost, heat waves,
epidemics, forest fires), geological hazards (landslides, snow
avalanches), tectonic hazards (earthquakes, volcanoes), and
technological hazards. This book provides a text and a resource on
environmental hazards for senior undergraduate students, graduate
students on all courses related to environmental hazards and risk
assessment and management. It is a valuable handbook for
researchers and professionals of environmental science,
environmental economics and management, and engineering. Editor:
