DOWNLOAD EBOOKDrawing on a number of case studies from around the world, this publication considers how the local knowledge and practices of indigenous fishing communities are being used in collaboration with scientists, government managers and non-governmental organisations to establish effective frameworks for sustainable fisheries science and management. It seeks to contribute towards achieving the goal of establishing international responsibility for the ethical collection, preservation, dissemination and application of fishers' knowledge.

DOWNLOAD EBOOKIt is almost thirty years since Professor G. G. Winberg established the basis for experimental studies in fish energetics with the publication of his monograph, Rate of Metabolism and Food Requirements of Fishes. His ultimate aim was to develop a scientific approach to fish culture and management, and the immense volume of literature generated in the ensuing years has been mainly in response to the demand for information from a rapidly expanding, world-wide aquaculture industry and to the shortcomings of contemporary practices in fisheries management. The purpose of this book is not to review this literature compre hensively, but, assuming an informed readership, to focus attention on topics in which new knowledge and theory are beginning to be applied in practice. Most emphasis has been placed on food; feeding; production (growth and reproduction) and energy budgeting, as these have most influence on the development of fish culture. Some chapters offer practical advice for the selection of methods, and warn of pitfalls in previous approaches. In others the influence of new theory on the interpretation of studies in fish energetics is discussed in the context of resource allocation and adaptation. We hope that the scope of material presented here will have sufficient interest and value to help significantly to fulfil Winberg's original objectives.

DOWNLOAD EBOOKWhether the result of an oil well blowout, vessel collision or grounding, leaking pipeline, or other incident at sea, each marine oil spill will present unique circumstances and challenges. The oil type and properties, location, time of year, duration of spill, water depth, environmental conditions, affected biomes, potential human community impact, and available resources may vary significantly. Also, each spill may be governed by policy guidelines, such as those set forth in the National Response Plan, Regional Response Plans, or Area Contingency Plans. To respond effectively to the specific conditions presented during an oil spill, spill responders have used a variety of response optionsâ€"including mechanical recovery of oil using skimmers and booms, in situ burning of oil, monitored natural attenuation of oil, and dispersion of oil by chemical dispersants. Because each response method has advantages and disadvantages, it is important to understand specific scenarios where a net benefit may be achieved by using a particular tool or combination of tools. This report builds on two previous National Research Council reports on dispersant use to provide a current understanding of the state of science and to inform future marine oil spill response operations. The response to the 2010 Deepwater Horizon spill included an unprecedented use of dispersants via both surface application and subsea injection. The magnitude of the spill stimulated interest and funding for research on oil spill response, and dispersant use in particular. This study assesses the effects and efficacy of dispersants as an oil spill response tool and evaluates trade-offs associated with dispersant use.

DOWNLOAD EBOOKThe Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

DOWNLOAD EBOOKThis textbook presents a comprehensive overview of the environmental impacts of various types of adventure tourism and how these can be best managed. This volume follows on from the authors previous textbook – ‘Outdoor Recreation: Environmental Impacts and Management’ and continues the aim of developing a deeper understanding of how tourist numbers impact the environment and to provide practical solutions to these problems. Combining their own first-hand experience and research with extensive literature review the authors' present several popular adventure tourism destinations from across the globe, including the Arctic, the Himalayas, Africa, Australia and Scotland as case studies. Chapters cover the particular challenges faced by each region: including impacts on animals and birds; the spread of invasive plant species and diseases; trail impacts on vegetation; impacts on geological, historical and archaeological sites and pollution and waste issues. A discussion and evaluation of the possible management actions for minimising these impacts and how outdoor recreation tourists can be regulated concludes each chapter. This practical and engaging textbook will be invaluable to students and scholars of adventure tourism and outdoor recreation as well as practitioners and managers working in the field.

DOWNLOAD EBOOKThis document provides a review, commentary and tabulations of the main trends that have occurred in exploitation of fisheries resources since the 1970s, largely as they are reflected in the FAO database on fishery landings, supplemented with selected information from the fishery literature. Reviews were prepared separately for the 15 main areas into which FAO divides the world's oceans for statistical purposes. They are then compared from a global perspective to reveal relative trends by species and areas, which are highlighted. Several special topics are reviewed, including tuna and tuna-like species, whales and dolphins, and environmental issues in fisheries.
