The Law of the Seabed reviews the most pressing legal questions raised by the use and protection of natural resources on and underneath the world’s seabeds. While barely accessible, the seabed plays a major role in the Earth’s ecological balance. It is both a medium and a resource, and is central to the blue economy. New uses and new knowledge about seabed ecosystems, and the risks of disputes due to competing interests, urge reflection on which regulatory approaches to pursue. The regulation of ocean activities is essentially sector-based, and the book puts in parallel the international and national regimes for seabed mining, oil and gas, energy generation, bottom fisheries, marine genetic resources, carbon sequestration and maritime security operations, both within and beyond the national jurisdiction. The book contains seven parts respectively addressing the definition of the seabed from a multidisciplinary perspective, the principles of jurisdiction delimitation under the United Nations Convention on the Law of the Sea (UNCLOS), the regimes for use of non-living, living and marine biodiversity resources, the role of state and non-state actors, the laying and removal of installations, the principles for sustainable and equitable use (common heritage of mankind, precaution, benefit sharing), and management tools to ensure coexistence between activities as well as the protection of the marine environment.

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.

This book on the current state of knowledge of submarine geomorphology aims to achieve the goals of the Submarine Geomorphology working group, set up in 2013, by establishing submarine geomorphology as a field of research, disseminating its concepts and techniques among earth scientists and professionals, and encouraging students to develop their skills and knowledge in this field. Editors have invited 30 experts from around the world to contribute chapters to this book, which is divided into 4 sections – (i) Introduction & history, (ii) Data & methods, (ii) Submarine landforms & processes and (iv) Conclusions & future directions. Each chapter provides a review of a topic, establishes the state-of-the-art, identifies the key research questions that need to be addressed, and delineates a strategy on how to achieve this. Submarine geomorphology is a priority for many research institutions, government authorities and industries globally. The book is useful for undergraduate and graduate students, and professionals with limited training in this field.

The deep sea covers over 60% of the surface of the earth, yet less than 1% has been scientifically investigated. There is growing pressure on deep-sea resources and on researchers to deliver information on biodiversity and the effects of human impacts on deep-sea ecosystems. Although scientific knowledge has increased rapidly in recent decades, there exist large gaps in global sampling coverage of the deep sea, and major efforts continue to be directed into offshore research. Biological Sampling in the Deep Sea represents the first comprehensive compilation of deep-sea sampling methodologies for a range of habitats. It reviews the real life applications of current, and in some instances developing, deep-sea sampling tools and techniques. In creating this book the authors have been able to draw upon the experiences of those at the coal face of deep-sea sampling, expanding on the existing methodological texts whilst encompassing a level of technical detail often omitted from journal publications. Ultimately the book will promote international consistency in sampling approaches and data collection, advance the integration of information into global databases, and facilitate improved data analyses and consequently uptake of science results for the management and conservation of the deep-sea environment. The book will appeal to a range of readers, including students, early-career through to seasoned researchers, as well as environmental managers and policy makers wishing to understand how the deep-sea is sampled, the challenges associated with deep survey work, and the type of information that can be obtained.

Human activities have taken place in the world's oceans and seas for most of human history. With such a vast number of ways in which the oceans can be used for trade, exploited for natural resources and fishing, as well as concerns over maritime security, the legal systems regulating the rights and responsibilities of nations in their use of the world's oceans have long been a crucial part of international law. The United Nations Convention on the Law of the Sea comprehensively defined the parameters of the law of the sea in 1982, and since the Convention was concluded it has seen considerable development. This Oxford Handbook provides a comprehensive and original analysis of its current debates and controversies, both theoretical and practical. Written by over forty expert and interdisciplinary contributors, the Handbook sets out how the law of the sea has developed, and the challenges it is currently facing. The Handbook consists of forty chapters divided into six parts. First, it explains the origins and evolution of the law of the sea, with a particular focus upon the role of key publicists such as Hugo Grotius and John Selden, the gradual development of state practice, and the creation of the 1982 UN Convention. It then reviews the components which comprise the maritime domain, assessing their definition, assertion, and recognition. It also analyses the ways in which coastal states or the international community can assert control over areas of the sea, and the management and regulation of each of the maritime zones. This includes investigating the development of the mechanisms for maritime boundary delimitation, and the decisions of the International Tribunal for the Law of the Sea. The Handbook also discusses the actors and intuitions that impact on the law of the sea, considering their particular rights and interests, in particular those of state actors and the principle law of the sea institutions. Then it focuses on operational issues, investigating longstanding matters of resource management and the integrated oceans framework. This includes a discussion and assessment of the broad and increasingly influential integrated oceans management governance framework that interacts with the traditional law of the sea. It considers six distinctive regions that have been pivotal to the development of the law of the sea, before finally providing a detailed analysis of the critical contemporary issues facing the law of the sea. These include threatened species, climate change, bioprospecting, and piracy. The Handbook will be an invaluable and thought-provoking resource for scholars, students, and practitioners of the law of the sea.

What constitutes animal welfare? With animals being used for companionship, service, research, food, fiber, and by-products, animal welfare is a topic of great interest and importance to society. As the world’s population continues to increase, a major challenge for society is the maintenance of a strong and viable food system, which is linked to the well-being and comfort of food animals. Animal Welfare in Animal Agriculture: Husbandry, Stewardship, and Sustainability in Animal Production explores the pressing issue of farm animal welfare in animal production systems in the United States and globally. A framework for open discussion on animal welfare, this multidisciplinary book brings together the perspectives of 40 highly qualified and recognized experts in their respective fields. Fourteen chapters address a range of topics that includes ethics, sociology, food safety, ecology, feed resources, biotechnology, government regulations, and sustainability, as well as animal comfort, health, and contributions to society. The book also offers a historical perspective on the growth of animal agriculture from family farms to industrial animal agriculture—and the impact this has had on society. Illustrating the diversity of viewpoints, the concept of animal welfare is defined from the perspectives of an ethicist and philosopher, a research scientist, a veterinarian, an industrialist, and an activist, as well as from the perspective of sustainability and product quality. Written primarily for students, but also highly relevant for professionals in varying fields of academia and industry, this timely book reveals important insights into animal welfare and animal agriculture. Unique in its depth, breadth, and balance, it underscores the need for dialogue on wide-ranging and often contentious issues related to animal production systems.

With shortages, volatile prices and nearly one billion people hungry, the world has a food problem - or thinks it does. Farmers, manufacturers, supermarkets and consumers in North America and Europe discard up to half of their food - enough to feed all the world's hungry at least three times over. Forests are destroyed and nearly one tenth of the West's greenhouse gas emissions are released growing food that will never be eaten. While affluent nations throw away food through neglect, in the developing world crops rot because farmers lack the means to process, store and transport them to market. But there could be surprisingly painless remedies for what has become one of the world's most pressing environmental and social problems. Travelling from Yorkshire to China, from Pakistan to Japan, and introducing us to foraging pigs, potato farmers, freegans and food industry directors, Stuart encounters grotesque examples of profligacy, but also inspiring innovations and ways of making the most of what we have. Combining front-line investigation with startling new data, Waste shows how the way we live now has created a global food crisis - and what we can do to fix it.
