Available in PDF, EPUB and Kindle. Book excerpt: En la segona meitat del segle XX, la industrialització dels vaixells pesquers va donar lloc a una sobreexplotació dels recursos marins a les àrees costeres dels estats tradicionalment pesquers. En conseqüència, els països pesquers industrialitzats van començar a explorar les aigües llunyanes, en gran part sense traves legals, per alimentar la creixent demanda de peix i marisc. Amb l'entrada en vigor de la Convenció de les Nacions Unides de 1982 sobre el Dret del Mar (UNCLOS, en anglès), així com l'Acord de Recursos Pesqueres ("Fish stock agreement") de les Nacions Unides de 1995, es van reestructurar radicalment els drets i les responsabilitats de la pesca de captura marina. No obstant això, aquestes noves legislacions van deixar molt d'espai a l'explotació econòmicament ineficient i ecològicament insostenible dels recursos pesquers. En tres assaigs, aquesta tesi dóna llum a la interacció entre les flotes industrialitzades d'aigües llunyanes i les regions sovint vulnerables on s'hi pesca. El primer assaig revisa críticament el desenvolupament de la pesca en aigües llunyanes en el món tropical durant els darrers 50 anys i ofereix una anàlisi quantitativa de la relació entre les flotes d'aigües llunyanes i els països tropicals d'acollida. Es conclou que hi ha un clar canvi de poder dels països tradicionalment pesquers als nouvinguts, sobretot asiàtics, i que els països petits i econòmicament febles són els més vulnerables a relacions d'explotació amb els estats que pesquen en aigües llunyanes. El segon assaig aborda la qüestió de si, des d'un punt de vista econòmic, els Països Insulars del Pacífic (PICs, en anglès) haurien de continuar concedint accés als estats pesquers d'aigües llunyanes, o si s'hauria d'intentar desenvolupar una indústria pròpia pesquera nacional. Amb aquesta finalitat, un nou model bioeconòmic amb múltiples espècies i actors és analitzat. Els resultats del model mostren que els PICs maximitzarien els seus beneficis mitjançant l'eliminació gradual dels acords d'accés amb els estats pesquers d'aigües llunyanes, substituint-los per un esforç pesquer nacional. L'alternativa és elevar considerablement les tarifes d'accés, tot i que, per descomptat, això pot tenir diferents conseqüències a llarg termini. En el tercer assaig, es descriu un model empíric per inferir el pes viu de la pesca de la tonyina vermella a l'Atlàntic Est i al Mediterrani (EBFT, en anglès) a partir de dades mensuals del comerç entre 2005 i 2011. En base a la captura total estimada, s'arriba a la conclusió que l'EBFT ha estat persistentment sobreexplotada al llarg de tot el període esmentat. En conclusió, aquesta tesi ha contribuït a la literatura tot estudiant l'impacte de la pesca en aigües llunyanes sobre la salut de les poblacions de peixos en alta mar i en les zones econòmiques exclusives en regions tropicals, així com en el benestar dels països en desenvolupament que són abundants en recursos pesquers.

Download or read book Alternative Arrangements for Marine Fisheries written by Francis T. Christy, Jr. and published by Routledge. This book was released on 2015-08-11 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The maintenance of the freedom of fishing in the face of the changing circumstances that were occurring at the time of this title’s original publication in 1973 had produced several damaging consequences. It had led to considerable waste, in both biological and economic terms, and had been the source of increasing conflict. This waste can only be prevented by the adoption of management measures and by the removal of the condition of free and open access. This book explores various techniques for this, and will be of interest to students of environmental management.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an up-to-date review of our current understanding of climate change in the North Sea and adjacent areas, as well as its impact on ecosystems and socio-economic sectors. It provides a detailed assessment of climate change based on published scientific work compiled by independent international experts from climate-related disciplines such as oceanography, atmospheric sciences, marine and terrestrial ecology, using a regional evaluation and review process similar to that of the Intergovernmental Panel on Climate Change (IPCC). It provides a comprehensive overview of all aspects of our changing climate, discussing a wide range of topics including past, current and future climate change, and climate-related changes in marine, terrestrial and freshwater ecosystems. It also explores the impact of climate change on socio-economic sectors such as fisheries, agriculture, coastal zone management, coastal protection, urban climate, recreation/tourism, offshore activities/energy, and air pollution.

Download or read book China s Distant water Fishing Fleet written by Miren Gutiérrez and published by . This book was released on 2021 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: With 16,966 vessels, China’s DWF fleet is 5–8 times larger than previous estimates. Trawlers are the most common DWF vessel, and most vessels are in the Northwest Pacific. Almost 1,000 Chinese DWF vessels are registered in other countries. The ownership and operational control of China’s DWF fleet is both complex and opaque. At least 183 vessels in China’s DWF fleet are suspected of involvement in IUU fishing. The Government of China can take steps to demonstrate global leadership on the governance of DWF, sustainability of global fisheries and combatting IUU. More work is needed to explore the ecological, social and economic impacts of China’s DWF fleet in developing countries, and to investigate the behaviour of transnational companies engaged in DWF, particularly those registered in flag-of-convenience states and tax havens.

Download or read book Ecosystems of the Deep Oceans written by P.A. Tyler and published by Elsevier. This book was released on 2003-03-27 with total page 581 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume examines the deep sea ecosystem from a variety of perspectives. The initial chapters examine the deep-sea floor, the deep pelagic environment and the more specialised chemosynthetic environments of hydrothermal vents and cold seeps. These environments are examined from the perspective of the relationship of deep-sea animals to their physico-chemical environment. Later chapters examine the biogeography of the main deep oceans (Atlantic, Pacific and Indian) with particular attention to the downward flux of surface-derived organic matter and how this drives the processes within the deep-sea ecosystem. The peripheral deep seas including the polar seas and the marginal deep seas (inter alia the Mediterranean, Red, Caribbean and Okhotsk seas) are explored in the same context. The final chapters examine the processes occurring in the deep sea and include an analysis of why the deep sea has high species diversity, how the fauna respond to organic input and how species have adapted reproductive activity in the deep sea. The volume concludes with an analysis of the anthropogenic impact on the deep sea.

Download or read book Freshwater Recreational Fishing written by William J. Vaughan and published by Routledge. This book was released on 2015-09-16 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Federal Water Pollution Control Act, signed into law in 1972, dramatically redirected the nation’s water pollution control efforts and set out ambitious national goals, expressed both in terms of discharge controls and of resulting water quality. Originally published in 1982, this title examines the benefits that a reduction in the discharge of water pollutants has for recreational fisherman including an increase in the total availability of fishable natural water bodies and an improvement in the aesthetic quality of the fishing experience. It is a valuable resource for students interested in environmental studies and public policy making.

Download or read book The State of World Highly Migratory Straddling and Other High Seas Fishery Resources and Associated Species written by Jean-Jacques Maguire and published by Food & Agriculture Org.. This book was released on 2006 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries for highly migratory species are important in all oceans and semi-enclosed seas, except for polar regions. Fisheries for straddling fish stocks are much more localised, primarily occurring in a few regions where continental shelves extend beyond the 200 miles Exclusive Economic Zone (EEZ), while most fisheries for other high seas fishery resources are deep-water fisheries. This publication examines issues relating to the stocks of these resources, including information on their state of exploitation. Findings include that about 30 percent of the stocks of highly migratory tuna and tuna-like species, more than half of highly migratory oceanic sharks and nearly two-thirds of the straddling stocks and the stocks of other high seas fishery resources are overexploited or depleted. Although the stocks concerned represent only a small fraction of the world fishery resources, they are key indicators of the state of an overwhelming part of the ocean ecosystem which appears to be more overexploited than EEZs.

Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Linking Social and Ecological Systems written by Fikret Berkes and published by Cambridge University Press. This book was released on 2000-04-13 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is usually the case that scientists examine either ecological systems or social systems, yet the need for an interdisciplinary approach to the problems of environmental management and sustainable development is becoming increasingly obvious. Developed under the auspices of the Beijer Institute in Stockholm, this new book analyses social and ecological linkages in selected ecosystems using an international and interdisciplinary case study approach. The chapters provide detailed information on a variety of management practices for dealing with environmental change. Taken as a whole, the book will contribute to the greater understanding of essential social responses to changes in ecosystems, including the generation, accumulation and transmission of ecological knowledge, structure and dynamics of institutions, and the cultural values underlying these responses. A set of new (or rediscovered) principles for sustainable ecosystem management is also presented. Linking Social and Ecological Systems will be of value to natural and social scientists interested in sustainability.
