Download or read book Ecosystem Based Management for the Oceans written by Karen McLeod and published by Island Press. This book was released on 2012-09-26 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional management approaches cannot meet the challenges faced by ocean and coastal ecosystems today. Consequently, national and international bodies have called for a shift toward more comprehensive ecosystem-based marine management. Synthesizing a vast amount of current knowledge, Ecosystem-Based Management for the Oceans is a comprehensive guide to utilizing this promising new approach. At its core, ecosystem-based management (EBM) is about acknowledging connections. Instead of focusing on the impacts of single activities on the delivery of individual ecosystem services, EBM focuses on the array of services that we receive from marine systems, the interactive and cumulative effects of multiple human activities on these coupled ecological and social systems, and the importance of working towards common goals across sectors. Ecosystem-Based Management for the Oceans provides a conceptual framework for students and professionals who want to understand and utilize this powerful approach. And it employs case studies that draw on the experiences of EBM practitioners to demonstrate how EBM principles can be applied to real-world problems. The book emphasizes the importance of understanding the factors that contribute to social and ecological resilience —the extent to which a system can maintain its structure, function, and identity in the face of disturbance. Utilizing the resilience framework, professionals can better predict how systems will respond to a variety of disturbances, as well as to a range of management alternatives. Ecosystem-Based Management for the Oceans presents the latest science of resilience, while it provides tools for the design and implementation of responsive EBM solutions.
Download or read book The Ecosystem Approach to Fisheries written by Gabriella Bianchi and published by CABI. This book was released on 2008 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Sustainable use of aquatic ecosystems is high on regional, national and international agendas and central to the implementation of international agreements on biological diversity, responsible fisheries and fish stock management. Since 2001, when political commitments were made to implement the ecosystem approach, countries have begun to incorporate ecosystem considerations into their fisheries management and have met with varied success." "The Ecosystem Approach to Fisheries covers both theoretical andapplied aspects of sustainable management, with a particular emphasis on reviewing concepts and addressing implementation issues in the form of case studies from around the world. Personal experiences are considered from diverse backgrounds and discuss the constraints encountered, strategies identified and best practices to facilitate further implementation."--BOOK JACKET.

[...] In relation to the diversity of the benthos, the spatial distribution of ecosystem types on the eastern Scotian Shelf could be defined, as well as the amount of total area of each type which is being used or impacted by human activities. [...] Trends and indicators for the oceanography, the benthos and biodiversity were covered on day two, while day three was devoted to presentations and discussion on the trends and indicators of the fisheries and the 13 Ecosystem Considerations Maritimes Region for the Eastern Scotian Shelf ecosystem. [...] The ESSIM initiative is the implementation of one of the recommendations from the 1998 Sable / Gully Conservation Strategy that integrated management approaches be applied to the larger ocean area surrounding the Gully AOI.
Download or read book Ecosystem Based Management for Marine Fisheries written by Andrea Belgrano and published by Cambridge University Press. This book was released on 2011-02-03 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Showing how big-picture patterns can help overcome the failures of conventional management, this book is ideal for students, researchers and professionals involved with marine fisheries. It explores not only the current practice of the 'ecosystem approach' to fisheries management but also its critical importance to even larger perspectives. The first section gives a valuable overview of how more and more of the complexity of real-world systems is being recognized and involved in the management of fisheries around the world. The second section then demonstrates how important aspects of real-world systems, involving population dynamics, evolution and behavior, remain to be taken into account completely. This section also shows how we must change the way we think about our involvement in, and the complexity of, marine ecosystems. The final chapters consider how, with the use of carefully chosen macroecological patterns, we can take important steps towards more holistic management of marine fisheries.
Download or read book Large Marine Ecosystems of the North Atlantic written by H.R. Skjoldal and published by Elsevier. This book was released on 2002-04-16 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ecosystem Ecology Research Trends written by Junying Chen and published by Nova Publishers. This book was released on 2008 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem ecology is the integrated study of biotic and abiotic components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. A major focus of ecosystem ecology is on functional processes, ecological mechanisms that maintain the structure and services produced by ecosystems. These include primary productivity (production of biomass), decomposition, and trophic interactions. Studies of ecosystem function have greatly improved human understanding of sustainable production of forage, fibre, fuel, and provision of water. Functional processes are mediated by regional-to-local level climate, disturbance, and management thus ecosystem ecology provides a powerful framework for identifying ecological mechanisms that interact with global environmental problems, especially global warming and degradation of surface water. This book presents the latest developments in the field from around the world.

This book was released on 2013 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Atlantic Zone Monitoring Program (AZMP) was implemented in 1998 with the aim of increasing Fisheries and Oceans Canada's (DFO's) capacity to understand, describe, and forecast the state of the marine ecosystem, and quantifying the changes in ocean physical, chemical, and biological properties. A critical element in the observational program of AZMP is an annual assessment of the distribution and variability of nutrients and the plankton they support. Herein, the optical, chemical, and biological oceanographic (lower trophic levels) conditions observed in 2012 in the Maritimes Region, including the Georges Bank/Gulf of Maine/Bay of Fundy system and the Scotian Shelf are reviewed. In the context of record warm conditions in 2012, this report focused on evaluating changes in phytoplankton and zooplankton annual production cycles and community composition.--Document.
