Download or read book Value and Economy of Marine Resources written by André Monaco and published by John Wiley & Sons. This book was released on 2014-12-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine resources and their exploitation, recovery and economic networks they generate are here from the perspective now inevitable growing environmental constraints, policy management and technical innovation. The recent development of marine biotechnology , the discovery of a great pharmacopoeia especially in reef environments , the development of marine renewables , are examples which show that man can develop through these new technologies property and services of the ocean. But this development resources under pressure of global change requires not only taking into account technical, but also social and political. This is the price that the analysis of maritime activities will assess the sustainability and development of various economic sectors and coastal populations, faced with the objectives of a "blue growth" associated with a return to the "good state" of the marine environment.

Download or read book Bioeconomics of Fisheries Management written by Lee G. Anderson and published by John Wiley & Sons. This book was released on 2011-11-18 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries Economics has always been an interdisciplinary field of study with economic analysis based on stock population dynamics, but many published works have focused mainly on theoretical economic issues without much focus on biological details. For the most part, age structured models have been ignored. Bioeconomics of Fisheries Management is a valuable reference text that presents the economic aspects of fisheries management in a broad bioeconomic framework. The book is broken into two parts. Part I covers the traditional areas of fisheries economics, covering topics such as open access, optimal and managed fisheries utilization that is analyzed through a traditional one stock/one fleet model. It also presents the basic results in terms of an age structured model. Part II covers material related to more recent work on bioeconomic models when more rigorous biological components became more prevalent, and views fisheries management with an ecosystems-based approach. Accompanying the book is a user-friendly CD with exercises and examples that aids the reader in applying theoretical principles of population dynamics and fisheries management and regulation. Bioeconomics of Fisheries Management will be a valuable text for researchers, fisheries economists, professionals, and students alike.

Download or read book Coastal Resources Economics and Ecosystem Valuation written by J.Walter Milon and published by MDPI. This book was released on 2019-12-12 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practical importance of economic valuation information can hardly be overstated. Coastal and marine resource policy planning and management benefit from complete information on the impact of policy decisions. In addition, proper accounting of the impacts of these policy decisions is necessary for benefit-cost analyses and measurements of economic growth over time. This special issue focuses on economic valuation of coastal and marine ecosystem services. Economic valuation provides methods and techniques to determine how changes in coastal and marine ecosystem services can be translated into benefits and costs to society. Economic values play an important role in everyday life and provide useful information about human welfare and happiness. Valuation provides a consistent framework to understand human-nature interactions across a broad range of coastal and marine resources, and to evaluate the costs and benefits of these interactions. The focus on ecosystem services provides new research on this perspective of human-nature interactions that has profoundly changed the academic dialogue on natural systems, but has had limited impact on public dialogue and the policy process.

Download or read book Fisheries Bioeconomics written by J. C. Seijo and published by Food & Agriculture Org.. This book was released on 1998 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is presented in seven Chapters. Chapter 1 describes the basic assumptions underlying the optimal allocation of natural resources and the inherent characteristics of fisheries that determine, under unrestricted access, the failure to allocate resources, economic inefficiency and overfishing. To mitigate these undesired effects, the bioeconomic literature invokes the allocation of property rights, which in turn must be implemented within a management context. Thus, in this Chapter we suggest some guidelines to conduct management plans. Static and dynamic bioeconomic models are presented in Chapter 2 as a theoretical framework for the design of intelligent management schemes aiming at sustainable use of fish stocks. Classic models are shown, such as the Gordon-Schaefer based on the logistic. We also develop new bioeconomic approaches, such as a distributed-delay model to add realism to Smith's fleet dynamics approach. Chapter 2 also includes an introductory version of a bioeconomic yield-mortality model, and dynamic age-structured models. A comparison of the dynamic and static trajectories is stressed. The price of time and its implications for optimal resource allocation over time is also discussed. For the sake of adding realism to the above models, the systems approach is used in Chapter 3 to model different technological and ecological complexities that occur in marine fisheries. Ecological interdependencies (competition, predation), as well as technological interdependencies resulting from fleets with different fishing power and/or gear types, operating on components of a stock, or on different target species of a "mixed stock", are specified and modelled.

Download or read book Fisheries Bioeconomics written by J.C. Seijo and published by Daya Books. This book was released on 2001 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overutilization of fish stocks, the overcapitalization of fisheries, the removal of associated benefits to society and growing concern over the conservation of marine biodiversity have resulted in a line of fisheries research that is multidisciplinary, dynamic and precautionary in approach. All the biological, ecological and economic factors need to be analysed if the forces regulating the dynamics of a fishery are to be appraised. This publication looks at the assumptions underlying the optimal allocation of renewable natural resources; lists the bioeconomic points of reference resulting from analysis of fisheries is supposed conditions of equilibrium; analysis bioeconomic models according to ecological interdependence factors (such as competition and predation) and technological factors (such as competition between fleets with different fishing capacity); offers a time-series analysis of fisheries and estimates the level of optimal effort; proposes mathematical models applied to bioeconomic analysis to support fisheries management plans; refutes the assumption of uniform resource distribution, incorporating a spatial dimension in fisheries dynamics analysis; and expounds basic elements of decision-making theory and criteria that reflect different attitudes to risk aversion in fisheries management.

Download or read book The Ecosystem Approach to Marine Planning and Management written by Sue Kidd and published by Routledge. This book was released on 2012-08-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The marine environment is one of our most precious yet fragile natural resources. It provides a wide range of essential goods and services, including food, regulation of climate and nutrient cycling, as well as a setting for transport, recreation and tourism. This environment is however extremely complex and very sensitive to development pressures and other forms of human influence. Planning and management of the sea are similarly complicated, reflecting intricate legal, institutional and ownerships patterns. This creates a situation where marine ecosystems are vulnerable to over-exploitation or neglect. The Ecosystem Approach to Marine Planning and Management describes how growing concern about the state of our seas is resulting in the development of new approaches to marine planning and management. For example, the United Nations Environment Programme has called for the widespread introduction of Marine Spatial Planning (MSP), and the European Union has recently been consulting on a new European Maritime Policy designed to stimulate economic growth but at the same time protect the resource base. Within the United Kingdom, the 2010 Marine Act draws upon the experience of town and country planning and brings into being a new system of Marine Spatial Planning. The authors show that a common feature of all these developments is an appreciation that more integrated forms of planning and management are required for our seas and that new arrangements must draw together understanding from natural science, social science and many other perspectives. Adopting such a trans-disciplinary and holistic (or 'ecosystems') approach, the book distils the expertise of these different disciplines and seeks to promote a broader understanding of the origins and practicalities of new approaches to marine planning and management.

Download or read book The Sunken Billions Revisited written by World Bank and published by World Bank Publications. This book was released on 2017-02-10 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report updates previous studies that measured in economic terms the extent of biological losses attributable to overfishing globally. The new estimates assess these 'sunken billions' at $83 billion annually. The report further shows that a clear path can lead to the recovery of these considerable losses, including through significant reduction in global fishing overcapacity. A breakdown between regions is also included, showing that the effort needed to achieve this reform will not be felt equally throughout the world. While the cost of such reform will likely be high, the expected benefits include an increase in biomass by a factor of 2.7, increase in annual harvests by 13 percent, and a 30-fold increase in annual net benefits accrued to the fisheries sector (from $3 billion to $86 billion annually). This urgent call for action is reinforced by the impacts of climate change on fish stocks and fisheries worldwide.

Download or read book Environmental Management of Marine Ecosystems written by Md. Nazrul Islam and published by CRC Press. This book was released on 2018-03-09 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystem-Based Management (EBM) is one of the most holistic approaches to protecting marine and coastal ecosystems as it recognizes the need to protect entire marine ecosystems instead of individual species. After decades of pollution, habitat degradation and overfishing, now climate change and ocean acidification threaten the health of the ocean in unprecedented way. Environmental Management of Marine Ecosystems illustrates the current status, trends, and effects of climate, natural disturbances and anthropogenic impacts on marine ecosystems. It demonstrates how to integrate different management tools and models in an up-to-date, multidisciplinary approach to environmental management. This indispensable guide provides several case studies from around the world and creates a framework for identifying management tools and their applications in coral reefs, fisheries, migratory species, marine islands and associated ecosystems such as mangroves and sea grass beds. It discusses the physical and chemical compositions of marine ecosystems along with the threats and actions needed to protect them. The application of model framework to several contemporary management issues include the modelling of harmful algal bloom dynamics, understanding the dispersal of sea lice, and the possible impacts on intertidal communities of the provision of novel offshore habitat. The results of extensive research by an international team of contributors, the Environmental Management of Marine Ecosystems is designed to inform scientists, practitioners, academics, government and non-government policymakers on the particularities of marine ecosystems and assist them in understanding the EBM approaches in means of mitigation and adaptation of human activities that result in sustainability. These practices will help change the current methodologies used for resource assessment and the future regulations of marine resources.

It also serves a broader purpose of providing stakeholders and policy actors in each of the world's sixty-four Large Marine Ecosystems, with a comparative example of the challenges and information needs required to implement principled ocean governance generally and marine EBM in particular, at multiple levels. Additionally, the volume serves to supplement the training of graduate level students in the marine sciences by enhancing interdisciplinary understanding of challenges in implementing marine EBM.

Download or read book Sustainable Natural Resource Management written by Daniel R. Lynch and published by Cambridge University Press. This book was released on 2009-03-02 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural resources support all human productivity. The sustainable management of natural resources is among the preeminent problems of the current century. Sustainability and the implied professional responsibility start here. This book uses applied mathematics familiar to undergraduate engineers and scientists to examine natural resource management and its role in framing sustainability. Renewable and nonrenewable resources are covered, along with living and sterile resources. Examples and applications are drawn from petroleum, fisheries, and water resources. Each chapter contains problems illustrating the material. Simple programs in commonly available packages (Excel, MATLAB) support the text. The material is a natural prelude to more advanced study in ecology, conservation, and population dynamics, as well as engineering and science. The mathematical description is kept within what an undergraduate student in the sciences or engineering would normally be expected to master for natural systems. The purpose is to allow students to confront natural resource problems early in their preparation.
