This book deals with sedimentary sulfides which are the most
abundant authigenic minerals in sediments.Special emphasis is given
to the biogeochemistry that plays such a central role in the
formation of sedimentary sulfides. It will be of interest to
scientists in a number of disciplines, including geology,
microbiology, chemistry and environmental science. The sulfur
system is important to environmental scientists considering the
present and future effects of pollution and anoxia.The development
of the sulfur system - particularly the characteristics of ocean
anoxia over the last 200 Ma - is useful in predicting the future
fate of the Earth surface system as well asin understanding the
past. The biochemistry and microbiology of the sulfur systemare key
to understanding microbial ecology and the evolution of life.
First monograph on sedimentary sulfides, covering the ancient and
modern sedimentary sulfide systemsComprehensive, integrating
chemistry, microbiology, geology and environmental scienceAll key
references are included and discussed

In Asia and the Pacific, climate change is now a well-recognised
risk to water security but responses to this risk are either under
reported, or continue to be guided by the incremental or business
as usual approaches. Water policy still tends to remain too narrow
and fragmented, compared to the multi-sectoral and cross-scalar
nature of risks to water security. What's more, current water
security debates tend to be framed in discipline specific or
academic ways, failing to understand decision making and
problem-solving contexts within which policy actors and
partitioners have to operate on a daily basis. Much of the efforts
to date has focussed on assessing and predicting the risks in the
context of increasing levels of uncertainty. There is still limited
analysis of emerging practices of risks assessment and mitigation
in different contexts in Asia and the Pacific. Going beyond the
national scales and focussing on several socio-ecological zones,
this book captures stories written by engaged scholars on recent
attempts to develop cross-sectoral and cross-scaler solutions to
assess and mitigate risks to water security across Asia and the
Pacific. Identifying lessons from successes and failures, it
highlights management and strategic lessons that water and climate
leaders of Asia and the Pacific need to consider. This book
showcases reflective and analytical thought pieces written by key
actors in the climate and water spaces. Several critical
socio-ecological zones are covered - from Pakistan in the west to
pacific islands in the east. The chapters clearly identify
strategies for improvement based on the analysis of emerging
responses to climate risks to water security and gaps in current
practices. The book will include an editorial introduction and a
final synthesis chapter to ensure clear articulation of common
themes and to highlight the overall messages of the book.
Examining the science of stream restoration, Rebecca Lave argues
that the neoliberal emphasis on the privatization and
commercialization of knowledge has fundamentally changed the way
that science is funded, organized, and viewed in the United States.
Stream restoration science and practice is in a startling state.
The most widely respected expert in the field, Dave Rosgen, is a
private consultant with relatively little formal scientific
training. Since the mid-1990s, many academic and federal agency -
based scientists have denounced Rosgen as a charlatan and a hack.
Despite this, Rosgen's Natural Channel Design approach,
classification system, and short-course series are not only
accepted but are viewed as more legitimate than academically
produced knowledge and training. Rosgen's methods are now promoted
by federal agencies including the Environmental Protection Agency,
the U.S. Forest Service, the U.S. Fish and Wildlife Service, and
the Natural Resources Conservation Service, as well as by resource
agencies in dozens of states. Drawing on the work of Pierre
Bourdieu, Lave demonstrates that the primary cause of Rosgen's
success is neither the method nor the man but is instead the
assignment of a new legitimacy to scientific claims developed
outside the academy, concurrent with academic scientists'
decreasing ability to defend their turf. What is at stake in the
Rosgen wars, argues Lave, is not just the ecological health of our
rivers and streams but the very future of environmental science.
CHECK DAM CONSTRUCTION FOR SUSTAINABLE WATERSHED MANAGEMENT AND
PLANNING Authoritative and comprehensive reference on the potential
for watershed development through the use of check dams Check Dam
Construction for Sustainable Watershed Management and Planning
summarizes current knowledge of check dams as key soil and water
conservation structures in some of the most sensitive and
vulnerable ecosystems in the world, as exemplified by the
Mediterranean area and the Chinese Loess Plateau, providing
detailed information on check dam design and watershed planning,
the use of advanced modeling techniques, challenges in dam
construction and how to overcome them. The work integrates decades
of research in the field of soil and water conservation and gully
management, including advanced studies in check dam construction
and watershed management. It also covers important new techniques
and methods, such as hydrological modeling, isotope tracing, and
more. To aid in reader comprehension, the five highly qualified
editors have divided the work into three distinct sections.
Sections I and II focus on the experience gained from the erosion
hotspots in the Chinese Loess Plateau, whereas Section III expands
the scope to other regions with different functions for check dams,
including headwater ecosystems and alpine environments. Sample
topics covered in Check Dam Construction for Sustainable Watershed
Management and Planning include: The regulating effect of check dam
systems on sediment redistribution and the formation and
development of dam systems in small watersheds Water and soil
conservation made possible by check dam construction and sediment
source analysis of water-sediment retarding effects of check dams
The regulation of check dam systems on the erosion dynamic process
and the mechanism of erosion reduction by check dams Flood control
risk assessment on warping dam systems and the development and
utilization model of check dam systems With its systematic coverage
of all aspects of dam construction and maintenance, Check Dam
Construction for Sustainable Watershed Management and Planning
supports decision making by local authorities and can also be used
as a professional guide for ecologists, hydrologists, and water
resource managers.
Few terms have garnered more attention recently in the sciences,
humanities, and public sphere than the Anthropocene, the proposed
epoch in which a human "signature" appears in the
lithostratigraphic record. Anthropocene Reading considers the
implications of this concept for literary history and critical
method. Entering into conversation with geologists and geographers,
this volume reinterprets the cultural past in relation to the
anthropogenic transformation of the Earth system while showcasing
how literary analysis may help us conceptualize this geohistorical
event. The contributors examine how a range of literary texts, from
The Tempest to contemporary dystopian novels to the poetry of Emily
Dickinson, mediate the convergence of the social institutions,
energy regimes, and planetary systems that support the reproduction
of life. They explore the long-standing dialogue between
imaginative literature and the earth sciences and show how
scientists, novelists, and poets represent intersections of
geological and human timescales, the deep past and a posthuman
future, political exigency and the carbon cycle. Accessibly written
and representing a range of methodological perspectives, the essays
in this volume consider what it means to read literary history in
the Anthropocene. Contributors include Juliana Chow, Jeffrey Jerome
Cohen, Thomas H. Ford, Anne-Lise Francois, Noah Heringman, Matt
Hooley, Stephanie LeMenager, Dana Luciano, Steve Mentz, Benjamin
Morgan, Justin Neuman, Jennifer Wenzel, and Derek Woods.
In 1997 sixty-two containers fell off the cargo ship Tokio Express
after it was hit by a rogue wave off the coast of Cornwall,
including one container filled with nearly five million pieces of
Lego, much of it sea themed. In the months that followed,
beachcombers started to find Lego washed up on beaches across the
south west coast. Among the pieces they discovered were octopuses,
sea grass, spear guns, life rafts, scuba tanks, cutlasses, flippers
and dragons. The pieces are still washing up today.
The Mediterranean region contains a diverse and interesting climate
ranging from areas with permanent glaciers to areas of subtropical,
semiarid regions. The region is potentially sensitive to climate
change and its progress has environmental, social, and economic
implications within and beyond the region. Produced by the
Mediterranean Climate Variability and Predictability Research
Networking Project, this book reviews the evolution of the
Mediterranean climate over the past two millennia with projections
further into the twenty-first century as well as examining in
detail various aspects of the Mediterranean region's climate
including evolution, atmospheric variables, and oceanic and land
elements. Integrated with this, the book also considers the social
and economic problems or vulnerabilities associated with the
region. Written and reviewed by multiple researchers to ensure a
high level of information presented clearly, Mediterranean Climate
Variables will be an invaluable source of information for
geologists, oceanographers, and anyone interested in learning more
about the Mediterranean climate.
