Book Description

Volume 111 of AAAS selected symposium, American Association of the Advancement of Science.




Food Chains, Yields, Models, And Management Of Large Marine Ecosoystems


Book Description

Draws on case studies from tropical, temperate, and Arctic waters around the world, comparing multispecies biomass yield models for various large marine ecosystems. Emphasis is given to adaptive management as a strategy for maximizing the sustainability and productivity of living marine resources.




Status and Future of Large Marine Ecosystems of the Indian Ocean


Book Description

This report signals a new approach to ocean monitoring and management that lays a solid base using the principles of ecology and sustainable development while transcending traditional geopolitical and disciplinary divisions. LMEs are relatively large regions, often including the territorial waters of more than one nation, thus making coordination of monitoring and management highly desirable.




Large Marine Ecosystems of the Indian Ocean


Book Description

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 Ecosystem Approach to Fisheries


Book Description

"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.




Fundamentals of Integrated Coastal Management


Book Description

by Elisabeth Mann Borgese Founder and Honorary President International Ocean Institute Adalberto Vallega has been, for decades, a master and great teacher of integrated coastal management and Mediterranean cooperation. This new book, of an almost en cyclopaedic scope, is a most original contribution to the rapidly growing literature on the subject, of equal value to the academic community which will greatly appreciate the theoretical, historic and philosophical underpinning of the work, and to the practi tioner, the planner, regulator and manager, who will find in these pages most useful "checklists" for his duties and responsibilities. Vallega perceives the need for Integrated Coastal Area Management (ICAM) in the broader context of the ongoing third industrial revolution, which he calls the trans-industrial stage, in its interaction with climate change. There have been profound changes in the economies of the industrialized coun tries. The development of the new High Technologies, including micro-electronics, genetic engineering, new materials, has accelerated the transition from an economic system based primarily on production to one based very largely on services. This, in turn, has facilitated "globalization" of production systems and services, including the financial system, as well as the migration of people The ongoing global "Great Peo ple's Migration" is, generally, from the hinterland to the coasts where, already today, over 60 percent of the human population resides, exercising unprecedented pressures on the coastal and marine environment. Clearly, this justifies the current emphasis, at global, regional and national levels, on the need for coastal management.




Southern Ocean Ecology


Book Description

BIOMASS (Biological Investigations of Marine Antarctic Systems and Stocks) was a unique, large-scale, long-term, international research programme established in 1977 to investigate the ecology of the Southern Ocean. Its main aim was to gain a greater understanding of the biological systems and stocks in the marine Antarctic environment, thereby providing a sound basis for the future management of the living resources within this immense ocean. The programme was drawn to a close in 1991 and its completion marked by a colloquium which brought together key researchers to summarise and review the results obtained. This volume, arising from that colloquium, provides a succinct, state-of-the-art account of the ecology of the Southern Ocean and serves as a comprehensive record of this unique and successful international project.







Evaluating and Monitoring the Health of Large-Scale Ecosystems


Book Description

Ecosystem health offers a fresh perspective on the management of natural resources and the environment. While some of the root concepts can surely be traced back to Aldo Leopold and even earlier, it is only in the recent decade that a substantial body of work has emerged on this topic. There is no question that a novel approach which is by its nature cross disciplinary, bridging the health and biological sciences, will initially raise a number of questions particularly pertaining to the use of metaphors and the validity of the analogy. This volume however goes beyond merely the philosophical dimensions of the subject by covering a number of case studies which have given rise to the development of promising quantitative methods for diagnosis and rehabilitation of ecosystems under stress. The focus of most studies is on regional ecosystems i.e. ecosystems of large scale. As such, the methods and approaches should have wide appeal to government agencies charged with the responsibility of sustainable development of regional ecosystems and natural resources. Health is one of those difficult concepts that everyone thinks they can define, until they come to try. We all have personal knowledge about health and illness and this makes the ecosystem analogy so potentially powerful. Yet it is also clear that the uncritical application of the concept could lead to overly simplistic approaches to analysis and management of ecosystem health.
