Viewed from the perspective of environmental management, this study
describes the implications and applications of the precautionary
principle - a theory of avoiding risk even when its likelihood
seems remote. This principle has been employed in the United
Nations Framework Convention on Climate Change and the North
Atlantic Convention, yet it is not widely understood. This study
examines the history and context of the principle, and its
applications to law, governmental policies, business and
investment, scientific research and international relations.
Time-variable exposure profiles of pesticides are more often the
rule than exception in the surface waters of agricultural
landscapes. There is, therefore, a need to adequately address the
uncertainties arising from time-variable exposure profiles in the
aquatic risk assessment procedure for pesticides. Linking Aquatic
Exposure and Effects: Risk Assessment of Pesticides provides
guidance and recommendations for linking aquatic exposure and
ecotoxicological effects in the environmental assessment of
agricultural pesticides. Leading international scientists share
their expertise in aquatic exposure assessment, aquatic
ecotoxicology, and the risk assessment and management of plant
protection products. The book incorporates the tools and approaches
currently available for assessing the environmental risks of
time-variable exposure profiles of pesticides. It also discusses
the science behind these techniques. This volume covers the
extrapolation techniques, including models that address the
environmental fate, toxicokinetics, toxicodynamics, and ecological
effects, for performing accurate aquatic environmental risk
assessments of pesticides. It explains how to link aquatic exposure
and effects in the risk assessment procedure for plant protection
products.
Based on discussions at the 2007 SETAC Europe PERAS Workshop in
Coimbra, Semi-Field Methods for the Environmental Risk Assessment
of Pesticides in Soil presents a timely summary of state-of-the-art
higher-tier terrestrial risk assessment of plant protection
products (PPPs). Influential regulators, academics, and industry
scientists provide a comprehensive, science-based view to guide
regulatory authorities and manufacturers in assessing the
higher-tier terrestrial risks of PPPs in the environment. The book
includes a clear description of how to perform a higher-tier
terrestrial risk assessment and provides a single reference on the
subject. It examines various types of semi-field methods for soil
assessment, including the use of terrestrial model ecosystems for
pesticide risk assessment. In addition, the text also explores
legislative and regulatory issues and offers technical
recommendations. The book provides guidance on how to assess the
soil risks of pesticides in the environment and explains how to use
semi-field methods to access how pesticides may lead to spatial and
temporal changes in soil biological communities and the larger
agricultural landscape.
A guide for students and professionals, this introductory course
book covers the basic principles of remote sensing and its
applications in mine environment monitoring. Building from a
reader's basic knowledge of mine monitoring, it teaches how to
implement remote sensing techniques and how to interpret the
acquired data for different purposes. Following a general
introduction to remote sensing principles and image analysis, mine
subsidence monitoring, slope stability monitoring, reclamation
planning and implementation, and post-closure mine and land use
analysis are explained and illustrated. With the help of case
studies, the techniques and tools presented are demonstrated. With
an increasing importance of sustainable mining, this accurate text
is intended for the education of university students in mining,
civil, geological and environmental engineering. Researchers and
professionals in these disciplines may find it beneficial as well
to guide their professional monitoring investigations.
This manual describes all aspects of a field seismic crew, on land,
in terms of their relevance to the activities of the birddog, who
is the company's representative on that field crew. In particular,
it descibes the essential functions of the birddog which are data
quality control (all forms) and testing to ensure optimum data
quality. Some fundamental concepts of the seismic methods are
described. Written in a way that is not specific to any particular
equipment or technology, it concentrates on the principles and
methods of supervision which are common to all procedures and
equipment.
This text challenges the belief that cities will eventually
disappear as territorial forms of social organization as new
information technologies permit the articulation of social
processes without regard for distance, arguing that the specific
role of cities will become more important, and proposing that a
dynamic and creative relationship be built up between the local and
the global. In this way, cities will remain the focus of social
organization, political management and cultural expression,
equipped to deal with the enormous social and environmental
problems of urbanization.
The benefits of modern technology often involve health, safety and
environmental risks that produce public suspicion of technologies
and aversion to certain products and substances. Amplified by the
pervasive power of the media, public concern about health and
ecological risks can have enormous economic and social impacts,
such as the 'stigmatization' experienced in recent years with
nuclear power, British beef and genetically modified plants. This
volume presents the most current and comprehensive examination of
how and why stigma occurs and what the appropriate responses to it
should be to inform the public and reduce undesirable impacts. Each
form of stigma is thoroughly explored through a range of case
studies. Theoretical contributions look at the roles played by
government and business, and the crucial impact of the media in
forming public attitudes. Stigma is not always misplaced, and the
authors discuss the challenges involved in managing risk and
reducing the vulnerability of important products, industries and
institutions while providing the public with the relevant
information they need about risks.
Thermodynamically constrained averaging theory provides a
consistent method for upscaling conservation and thermodynamic
equations for application in the study of porous medium systems.
The method provides dynamic equations for phases, interfaces, and
common curves that are closely based on insights from the entropy
inequality. All larger scale variables in the equations are
explicitly defined in terms of their microscale precursors,
facilitating the determination of important parameters and
macroscale state equations based on microscale experimental and
computational analysis. The method requires that all assumptions
that lead to a particular equation form be explicitly indicated, a
restriction which is useful in ascertaining the range of
applicability of a model as well as potential sources of error and
opportunities to improve the analysis.

Mixture concepts are nowadays used in a great number of subjects of
the - ological, chemical, engineering, natural and physical
sciences (to name these alphabetically) and the theory of mixtures
has attained in all these dis- plines a high level of expertise and
specialisation. The digression in their development has on occasion
led to di?erences in the denotation of special formulations as
'multi-phase systems' or 'non-classical mixtures', 'structured
mixtures', etc., and their representatives or defenders often
emphasise the di?erences of these rather than their common
properties.

Developed for use as a reference work in graduate and undergraduate
courses as well as for researchers, policymakers, and interested
laypersons, the book is a unique collection of authoritative yet
accessible journal articles about risk. Drawn from a variety of
disciplines including the physical and social sciences,
engineering, and law, the articles deal with a wide range of public
policy, regulatory, management, energy, and environmental issues.
The selections are accompanied by introductory notes, questions for
thought and discussion, and suggestions for further reading.
This book bridges the gap between theory and practice, showing how
a detailed definition of the shear-wave velocity (VS) profile can
be efficiently obtained using limited field equipment and following
simple acquisition procedures. It demonstrates how surface waves
(used to define the VS profile) and vibration data (used to
describe the dynamic behaviour of a building) can be recorded using
the same equipment, and also highlights common problems,
ambiguities and pitfalls that can occur when adopting popular
methodologies, which are often based on a series of simplistic
assumptions. Today, most national and international building codes
take into account a series of parameters aimed at defining the
local seismic hazard. Sites are characterised based on the local VS
profile, and the dynamic behaviour of existing buildings is defined
through the analysis of their eigenmodes. The book includes a
series of case studies to help readers gain a deeper understanding
of seismic and vibration data and the meaning (pros and cons) of a
series of techniques often referred to as MASW, ESAC, SPAC, ReMi,
HVSR, MAAM and HS. It also provides access to some of the datasets
so that readers can gain a deeper and more concrete understanding
of both the theoretical and practical aspects.

Here, the authors present modern mathematical methods to solve
problems of differential-operator inclusions and evolution
variation inequalities which may occur in fields such as
geophysics, aerohydrodynamics, or fluid dynamics. For the first
time, they describe the detailed generalization of various
approaches to the analysis of fundamentally nonlinear models and
provide a toolbox of mathematical equations. These new mathematical
methods can be applied to a broad spectrum of problems. Examples of
these are phase changes, diffusion of electromagnetic, acoustic,
vibro-, hydro- and seismoacoustic waves, or quantum mechanical
effects. This is the first of two volumes dealing with the subject.
The critically acclaimed serialized review journal for over 50
years, Advances in Geophysics is a highly respected publication in
the field of geophysics. Since 1952, each volume has been eagerly
awaited, frequently consulted, and praised by researchers and
reviewers alike. Now in its 55th volume, it contains much material
still relevant today--truly an essential publication for
researchers in all fields of geophysics.
The contributions to this book follow a topical trend. In several
geophysical fields evidence is accumulating concerning the
deviation of the earth's structure from radial symmetry. Seismology
provides the most adequate resolution for revealing the earth's
lateral inhomogeneity on a global to local scale. Lateral structure
in the density distribution is also manifest in the earth's gravity
field and in the geoid. Asphericity in physical parameters,
generally supposed only to vary with the vertical coordinate, has a
profound influence on geodynamics. The effects of these deviations
from spherical symmetry concern in particular convection theory,
post-glacial rebound and the dynamics of the lithosphere and upper
mantle in general. At the 16th International Conference on
Mathematical Geophysics which was held in Oosterbeek, the
Netherlands, in 1986, the need was felt to present the state of the
art. Several prospective authors were found interested to
contribute to the present book. This Oosterbeek conference was one
in a long series of topical conferences starting with the Upper
Mantle Project Symposia on Geophysical Theory and Computers in the
1960s, and thence their successors, the conferences on Mathematical
Geophysics, until the present.

The subject of wavelet analysis and fractal analysis is fast
developing and has drawn a great deal of attention in varied
disciplines of science and engineering. Over the past couple of
decades, wavelets, multiresolution, and multifractal analyses have
been formalized into a thorough mathematical framework and have
found a variety of applications with significant impact in several
branches of earth system sciences. Wavelets and Fractals in Earth
System Sciences highlights the role of advanced data processing
techniques in present-day research in various fields of earth
system sciences. The book consists of ten chapters, providing a
well-balanced blend of information about the role of wavelets,
fractals, and multifractal analyses with the latest examples of
their application in various research fields. By combining basics
with advanced material, this book introduces concepts as needed and
serves as an excellent introductory material and also as an
advanced reference text for students and researchers.
Presenting a rigorous treatment of the physical and mechanical
basis for the modelling of sedimentary basins, this book supplies
geoscientists with practical tools for creating their own models.
It begins with a thorough grounding in properties of porous media,
linear elasticity, continuum mechanics and rock compressibility.
Chapters on heat flow, subsidence, rheology, flexure and gravity
consider sedimentary basins in the context of the Earth's
lithosphere, and the book concludes with coverage of pore space
cementation, compaction and fluid flow. The volume introduces
basic, state-of-the-art models and demonstrates how to reproduce
results using tools like MATLAB (R) and Octave. Main equations are
derived from first principles, and their basic solutions are
obtained and then applied. Separate notes sections supply more
technical details, and the text is illustrated throughout with
real-world examples, applications and test exercises. This is an
accessible introduction to quantitative modelling of basins for
graduate students, researchers and oil industry professionals.
