Marrakech, Morocco, 20–25 March 2017 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-06-01 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most contentious issues in management of marine fisheries is the use of mobile bottom contacting gears, mainly trawls and dredges. There are growing concerns about the overall ecosystem impacts of bottom trawling. Some countries have banned bottom trawling and some major retailers refuse to stock fish caught using bottom trawl gears. However, such decisions are not always based on the best available scientific advice. The initiative “Finding common ground on the scientific knowledge regarding trawling best practices (TBP)” is an international collaboration of leaders in the scientific community to understand how trawling and other forms of towed bottom-contacting gears interact with seabed habitats and their biota. An analysis of the datasets to which the project has had access has revealed an underrepresentation of fisheries from tropical regions. Bottom trawl fishery is important in the region because it provides food and livelihoods for a large number of people. The TBP project in collaboration with FAO held an expert workshop in 2014 in Bangkok (Thailand) covering South and Southeast Asia and another workshop in 2016 in Cartagena (Colombia) covering the Latin American region. It was considered important to address the data gap and to engage stakeholders in Africa to raise awareness about potential best practices for trawling. Therefore, the TBP project, in collaboration with FAO, conducted a workshop on use of best available science in developing and promoting best practices for trawl fishing operations in Africa in March 2017 in Marrakech, Morocco. Key research institutions, universities, organizations and independent experts involved in data collection and research on assessment and/or management of ecosystem impacts of bottom trawling in Africa were invited to attend the workshop. The workshop first summarized the progress made in the five phases of the project and then (i) identified availability of data on spatial distribution of trawling activities, source of data as well as gaps in knowledge in the African region; (ii) evaluated availability and applicability of data on habitat, bycatch and ecosystem impacts of bottom trawling in the region; (iii) began to assemble data on trawling intensity in representative ecosystems; and (iv) developed an arrangement for expertise and data sharing, and for continuing to collaborate to develop best practices for trawling to enhance sustainability of marine ecosystem that contribute to food security and livelihoods in Africa.

This book was released on 2021-10-25 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical report describes efforts to mitigate bycatch through gear modifications and adaptations in the tropical shrimp-trawl fisheries of over 30 countries. It provides a summary of efforts by each country and then synthesizes them to identify and describe best practice. A best practice in bycatch reduction is the application or adoption of appropriate, recognized approaches to modifying fishing gear, with the objective of reducing bycatch to the greatest extent practicable. This information serves as a benchmark to identify countries that are taking appropriate steps to reduce bycatch and those that are not. It also provides context from which the outcomes of research on bycatch reduction can be evaluated and compared, including the identification of effective bycatch reduction devices, and serves to identify future research priorities. In the context of this report, best practice includes the installation and use of TEDs and BRDs that are optimally rigged and operated so as to reduce bycatch. It also includes the application of appropriate regulations to ensure effective performance, as well as the introduction of effective outreach and extension programmes to enhance and sustain best practice to reduce bycatch.

Available in PDF, EPUB and Kindle. Book excerpt: Underwater Acoustic Modeling and Simulation, Fourth Edition continues to provide the most authoritative overview of currently available propagation, noise, reverberation, and sonar-performance models. This fourth edition of a bestseller discusses the fundamental processes involved in simulating the performance of underwater acoustic systems and emphasizes the importance of applying the proper modeling resources to simulate the behavior of sound in virtual ocean environments. New to the Fourth Edition Extensive new material that addresses recent advances in inverse techniques and marine-mammal protection Problem sets in each chapter Updated and expanded inventories of available models Designed for readers with an understanding of underwater acoustics but who are unfamiliar with the various aspects of modeling, the book includes sufficient mathematical derivations to demonstrate model formulations and provides guidelines for selecting and using the models. Examples of each type of model illustrate model formulations, model assumptions, and algorithm efficiency. Simulation case studies are also included to demonstrate practical applications. Providing a thorough source of information on modeling resources, this book examines the translation of our physical understanding of sound in the sea into mathematical models that simulate acoustic propagation, noise, and reverberation in the ocean. The text shows how these models are used to predict and diagnose the performance of complex sonar systems operating in the undersea environment.

Available in PDF, EPUB and Kindle. Book excerpt: This book fills an important gap in the literature, and presents contributions from scientists and researchers working in the field of sustainable development who have engaged in dynamic approaches to implementing sustainability in higher education. It is widely known that universities are key players in terms of the implementation and further development of sustainability, with some having the potential of acting as “living labs” in this rapidly growing field. Yet there are virtually no publications that explore the living labs concept as it relates to sustainability, and in an integrated manner. The aims of this book, which is an outcome of the “4th World Symposium on Sustainable Development at Universities” (WSSD-U-2018), held in Malaysia in 2018, are as follows: i. to document the experiences of universities from all around the world in curriculum innovation, research, activities and practical projects as they relate to sustainable development at the university level; ii. to disseminate information, ideas and experiences acquired in the execution of projects, including successful initiatives and good practice; iii. to introduce and discuss methodological approaches and projects that seek to integrate the topic of sustainable development in the curricula of universities; and iv. to promote the scalability of existing and future models from universities as living labs for sustainable development. The papers are innovative, cross-cutting and many reflect practice-based experiences, some of which may be replicable elsewhere. Also, this book, prepared by the Inter-University Sustainable Development Research Programme (IUSDRP) and the World Sustainable Development Research and Transfer Centre (WSD-RTC), reinforces the role played by universities as living labs for sustainable development.

This book was released on 2020-12-14 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This third edition of the State of Mediterranean and Black Sea Fisheries provides a comprehensive overview of the status of fisheries in the region, looking at their main features and trends, in order to better inform their management and better examine current and future challenges that they will face in the near future. The aim of this report is to produce a document that could provide useful analysis and direction for decision-making and future action. In this respect, this publication also represents a convenient source of information for the FAO Committee on Fisheries and offers a practical complement to the data provided in the State of World Fisheries and Aquaculture published by the FAO Fisheries and Aquaculture Department. This volume includes seven chapters divided into two sections: a first part on the status and trends of different aspects of Mediterranean and Black Sea fisheries, including fleet, catches, socio-economic variables and bycatch, and a second part that focuses on the management of Mediterranean and Black Sea fisheries, including an overview on small-scale fisheries. This report is based to a large extent on the most up-to-date data available submitted by GFCM contracting and cooperating non-contracting parties, including information on stock status, national catches, fleet and socio-economic information up to 2018. It is also complemented with information from other sources.

Available in PDF, EPUB and Kindle. Book excerpt: While economic and social indicators in many Middle East and North Africa (MENA) countries have improved over the past three decades, the region’s blue natural assets—clean air, healthy seas, and coastlines—have degraded virtually everywhere. Air pollution levels in the region’s cities are among the highest in the world. Per capita marine plastic pollution is among the highest in the world; coastal erosion rates are the second fastest in the world. These combined challenges threaten local communities, livelihoods, and economies. In fact, the economic cost of MENA’s deteriorating skies and seas is estimated at more than 3 percent of GDP per year. Blue Skies, Blue Seas: Air Pollution, Marine Plastics, and Coastal Erosion in the Middle East and North Africa reviews integrated solutions that the authors identify as the “four I’s†?: • Inform stakeholders about the sources of these challenges. • Provide incentives that improve environmental outcomes for the public and the private sector. • Strengthen institutions to lower air and plastic pollution and to mitigate uncontrolled development and erosion of coastlines. • Invest in abatement options and promote sustainable solutions. Restoring MENA’s blue skies and seas will benefit the health, livelihoods, and incomes of residents. There will inevitably be trade-offs, but choosing a path of green growth will create jobs, diversify economies, and make the region a better place for current and future generations. The actions of policy makers today will shape the trajectory of economies and communities for decades to come.

This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
