Available in PDF, EPUB and Kindle. Book excerpt: The present book summarizes parts of the research made in the Norwegian Multispecies program. This program was initiated by the then Norwegian Council of Fisheries Research, which was later integrated in The Research Council of Norway. Modelling has been a key element in the program. In the first place, modelling, be it singlespecies or multispecies modelling, is an efficient way of summing up existing knowledge, and performing analyses of different types on the basis of it. Further more, models may serve as a meeting ground between fishery researchers from differ ent academic fields. This has been an important aspect of the Multispecies program, bringing together oceanographers, biologists, economists, mathematicians and stat isticians in fruitful cooperation. That this has proved possible may be taken as an important result of the program. The multispecies aspect has perhaps underscored the need for inter-disciplinary cooperation. The different authors are, of course, responsible for their respective contributions. Technical assistance in preparing the manuscript has been given by Knut Arrestad and Ian Knutsen, both at the University of Bergen. Bergen, October 1997.

This book was released on 2012-12-06 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this study is twofold: to provide a theoreti cal and an applied analysis of multispecies fisheries. The theoretical part will include concepts and analysis which, hopefully, will be of interest not only to economists, but also to biologists and ecologists. The application of the theoreti cal model and analysis to the Barents Sea fisheries gives empiri cal content to the analysis, which is important for the advance ment of fisheries management science. It is also my firm belief that this kind of work in the end will be beneficial to the people trying to make a living from harvesting marine resources. For thousands of years man has been whaling, sealing and fishing in these cold and harsh surroundings. The relative importance of the different species in the ecosystem has changed throughout history. In the seventeenth century the abundant, slow-swimming Greenland right whale and the Biscayan right whale in the Barents Sea area were so valuable, especially to English and Dutch whalers, that the intensive exploitation of these common property resources probably were the main reason for the extinction of these two stocks. The two species are, however, still present in other parts of the North Atlantic Ocean. Except for these two stocks of whales there is no knowledge of other stocks of sea mammals or fish in this area being extinct in historical time.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive analysis of the legal and policy frameworks for marine fisheries management and examines the efficiency of the institutions responsible for the formulation, implementation and enforcement of marine fisheries laws and policies in Bangladesh. Sustainable management of marine fisheries is a complex, multi-dimensional and multi-stakeholder process that entails sustainable use of marine living resources and conservation of marine biodiversity. Offering a critical analysis to these frameworks that play a crucial role in the conservation and management of fish stocks in areas within and beyond national jurisdiction, this book examines inadequacies and implementation gaps in the legislative, policy and institutional frameworks that contribute to the unsustainable exploitation of marine fish stocks in Bangladesh. It recommends law and policy reform for conservation and sustainable management of marine fisheries in Bangladesh and the Bay of Bengal.

Available in PDF, EPUB and Kindle. Book excerpt: Quantitative modeling methods have become a central tool in the management of harvested fish populations. This book examines how these modeling methods work, why they sometimes fail, and how they might be improved by incorporating larger ecological interactions. Fisheries Ecology and Management provides a broad introduction to the concepts and quantitative models needed to successfully manage fisheries. Walters and Martell develop models that account for key ecological dynamics such as trophic interactions, food webs, multi-species dynamics, risk-avoidance behavior, habitat selection and density-dependence. They treat fisheries policy development as a two-stage process, first identifying strategies for varying harvest in relation to changes in abundance, then finding ways to implement such strategies in terms of monitoring and regulatory procedures. This book provides a general framework for developing assessment models in terms of state-observation dynamics hypotheses, and points out that most fisheries assessment failures have been due to inappropriate observation model hypotheses rather than faulty models for ecological dynamics. Intended as a text in upper division and graduate classes on fisheries assessment and management, this useful guide will also be widely read by ecologists and fisheries scientists.

Book excerpt: Although the progress of environmental restoration projects in the Florida Everglades remains slow overall, there have been improvements in the pace of restoration and in the relationship between the federal and state partners during the last two years. However, the importance of several challenges related to water quantity and quality have become clear, highlighting the difficulty in achieving restoration goals for all ecosystem components in all portions of the Everglades. Progress Toward Restoring the Everglades explores these challenges. The book stresses that rigorous scientific analyses of the tradeoffs between water quality and quantity and between the hydrologic requirements of Everglades features and species are needed to inform future prioritization and funding decisions.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainability rests on the principle that we must meet the needs of the present without compromising the ability of future generations to meet their own needs. Starving people in poor nations, obesity in rich nations, increasing food prices, on-going climate changes, increasing fuel and transportation costs, flaws of the global market, worldwide pesticide pollution, pest adaptation and resistance, loss of soil fertility and organic carbon, soil erosion, decreasing biodiversity, desertification, and so on. Despite unprecedented advances in sciences allowing to visit planets and disclose subatomic particles, serious terrestrial issues about food show clearly that conventional agriculture is not suited any longer to feed humans and to preserve ecosystems. Sustainable agriculture is an alternative for solving fundamental and applied issues related to food production in an ecological way. While conventional agriculture is driven almost solely by productivity and profit, sustainable agriculture integrates biological, chemical, physical, ecological, economic and social sciences in a comprehensive way to develop new farming practices that are safe and do not degrade our environment. In that respect, sustainable agriculture is not a classical and narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. As most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world. This book gathers review articles that analyze current agricultural issues and knowledge, then propose alternative solutions. It will therefore help all scientists, decision-makers, professors, farmers and politicians who wish to build a safe agriculture, energy and food system for future generations.

Book excerpt: 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.

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.
