The Pacific Rim - a vast area of the globe taking in one third of the world's population and a diversity of economic, climatic and ecological conditions - is also one of the fastest developing. The imbalance between short-term economic gain and longer-term socioeconomic benefit is diminishing the value of the marine resources of the Pacific Rim at a critical point in time. Human interventions and climate change have altered the productivity of the large marine ecosystems (LMEs) of the Pacific and put the region under tremendous stress. Fortunately both the global environmental community and local interests are sensitive to these pressures and keen to assess, monitor and mitigate them through concerted action. Containing contributions from Asian, Australian and North American scientists and policy-makers, particular attention is paid to those LMEs under the greatest pressures, for example the LMEs of the Yellow Sea and South China Seas. The transboundary marine resources within these LMEs are unmanaged and continue to be subjected to unsustainable human activities including overexploitation of fisheries, coastal pollution, and the continuing loss of coastal habitat. Timely and hugely informative, this book contains a wealth of recommendations to guide future management practices for the region. The eight case studies illustrate the emerging trends in changing biomass yields and offer useful insights for future studies. With the initiation of science-based management practices, this book demonstrates how these LMEs can provide a more sustainable source of economic growth, improved food security, and nutritional benefits than is presently being realized.

This is the first book to provide assessments of multidecadal changes in resources and environments of the Large Marine Ecosystems (LMEs) of the North Atlantic. Using the case study method, researchers examine the forces driving the changes and actions underway aimed at turning the corner from declining trends in biomass yields, toward recovery of depleted species populations and improvements in ecosystem integrity. Recently a distinguished group of 24 scientists argued eloquently that a new Sustainability Science was emerging that was focused on "meeting fundamental human needs while preserving the life support systems of planet Earth". The contributions contained in this volume are at the cutting edge of Sustainability Science and the results presented by the contributors are pertinent to one of the core questions: "How are long-term trends in environment and development, including consumption and population, reshaping nature-society interactions in ways relevant to sustainability?" (Science Vol. 292, 27 April 2001). The case studies demonstrate the utility of an ecosystem-based approach to the assessment and management of biomass yields and species sustainability. Movements toward ecosystem-based management have emerged from the case studies on the initiation of recoveries of several depleted groundfish stocks of the US Northeast Shelf LME; the collapse of the Newfoundland-Labrador Shelf cod; the assessment of physical and biological changes on the Scotian Shelf, West Greenland Shelf, Iceland Shelf LME, and the Faroe Plateau, the North Sea, and the Barents Sea LMEs. Uncertainties, with regard to environmental and human-generated forcing, are addressed in assessment of the states of the Iberian Coastal and Biscay-Celtic LMEs, and in broad-scale studies of the influences at the base of the food chain of climatic variability on the productivity and biodiversity of plankton communities of the North Atlantic. The volume concludes with an insightful perspective on the approaches used and the results reported by the eminent marine scientist and former President of ICES, Professor Gotthilf Hempel.

In this volume marine experts from countries of East Africa and southern Asia describe the conditions of marine resources of the large marine ecosystems of the Indian Ocean. Countries of the region represent over a quarter of the world's population, most of whom are existing at or below the poverty level. The potentials for economic growth through the development of coastal tourism, mariculture, fisheries, mineral extraction, and oil and gas production are examined by the authors in relation to the need for ensuring the long-term sustainability of marine resources. Case studies of resource assessments presented by several authors illustrate the magnitude of risk from continuing degradation of resources under the prevailing unmanaged conditions extending over much of coastal areas of East Africa and southern Asia. The authors explore the application of multidisciplinary ecosystem-based assessment and management strategies to the future economic development of the large marine ecosystems of the region. With the initiation of science-based management practcies, the ecosystems of the area can provide an important source of economic growth, improved food security, and nutritional benefits to the populations of stakeholders in coastal areas bordering the Indian Ocean

The shift away from the management of individual resources to the broader perspective of ecosystems is no longer confined to academia and think tanks where it first began; the ecosystem paradigm also is beginning to take root in government policy and programs. This volume provides innovative and timely approaches for improving and sustaining socioeconomic benefits from LMEs. The authors describe methodologies and actions for moving forward in halting the downward resource sustainability spiral and advancing toward the recovery of depleted fish stocks, restoration of degraded habitats, and reduction and control of pollution within the framework of an ecosystem-based approach for the governance of LMEs. * First book to ever publish that focuses on the human dimension of large marine ecosystem management * Offers set of guidelines for possible interrelationship management programs * Addresses taxing issues and problems pertaining to the world's marine ecosystems * Provides a matrix of the interdependence of economic, social, cultural and governance elements

The Gulf of Guinea volume is part of a series on the Large Marine Ecosystems. This volume combines the latest research on the Gulf of Guinea from scientists working primarily in the region and from Europe. It covers the dynamics of the oceanic and coastal waters of the region, the major biological resources, pollution in the marine environment and the socio-economics and governance of marine fisheries. A significant number of new data sets, including some which have been repatriated from outside the region, are now made available through this publication. The combination of the various chapters underlines the interlinkages that exist between the interannual and seasonal dynamical behaviour of the oceanic offshore waters and the living marine resources along the coast, and the direct effect they have on the livelihoods of the populations living throughout the Gulf of Guinea. The volume is intended for those who have a general interest in the region as well as those who work professionally in the field. It will also be of immense value to resource managers and policy-makers as a demonstration project on how research can help solve the pressing problems of economic and food security in coastal regions.

The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
