Book Description
This book explores the types of conflicts that occur over marine and coastal resources, the underlying causes, and attempts to prevent them. Despite the emergence of various marine and coastal governance approaches to address the effects of human activities within the marine environment, conflict continues. In this book, the author outlines the reasons conflicts can, and do, arise in the marine and coastal environment. Drawing on case studies from both the northern and southern hemispheres, the book takes a broad view of how we interact with our environment, of how and why conflict is perpetuated as a political and cultural phenomenon, and how this varies or remains constant across space and place. The case studies explore not only the underlying perceptions and needs of those involved in marine and coastal conflict and the types of conflicts that arise in oceanic and coastal areas, but also the underpinning reasons for these conflicts. Marine and coastal resource conflicts have the potential to derail conservation efforts and blue growth policies, as well as the United Nations Sustainable Development Goals. Thus, it is imperative we understand the drivers and exacerbating factors of marine and coastal conflict. Arguing that there is an urgent need for renewed thinking and focus on conflict prevention, the author develops a theory of marine and coastal conflict which allows us to understand those factors and the means to help prevent such conflicts arising in the first place. This book will be of interest to students and researchers of coastal and marine science and environmental management as well as those working in the field of marine resource management, including coastal zone managers and fisheries managers.

State Ocean Jurisdiction
Author: Patrick Henri Ghislain Vrancken
Publisher: Taylor & Francis
ISBN: 1000901300
Category : Law
Languages : en
Pages : 246
Book Description
Proposing a systematic analytical framework which assists in understanding and applying the international law regime governing State ocean jurisdiction with a view to improved ocean governance for sustainable development, this book distinguishes between, and focuses on, the form, the ground, the scope and the purpose of State ocean jurisdiction. Defining jurisdiction as the international-law authority of a State to be involved in a factual matter on the basis of a valid legal ground to perform authoritative acts impacting on that matter, it disaggregates the concept the complexity of which often leads to States failing to make full use of their existing ocean jurisdictions. In the process, it identifies when and to what extent there are gaps and overlaps of jurisdictions. Bringing clarity on an inevitably complex and often misunderstood framework that is aimed at striking a universally accepted balance of competing interests, the book lays the foundation for future research, contextualising the position of State ocean jurisdiction not only in terms of ocean governance, but in the whole of public international law. With an original systematic focus on State ocean jurisdiction, the book will be of interest to academics, students and practitioners working in the areas of international law of the sea, ocean governance, human rights and environmental law.

Marine and Fisheries Policies in Latin America
Author: Manuel Ruiz Muller
Publisher: Routledge
ISBN: 0429761236
Category : Law
Languages : en
Pages : 193
Book Description
This book reviews the frameworks and implementation of marine, fishery and coastal laws and policies in Chile, Mexico and Peru. Chile, Mexico and Peru share biodiverse coastal and marine environments which are being affected by unregulated and informal developments, and thus share similar challenges. Each country is currently at a different stage of advancement in their institutional response to these complex challenges. By providing a comparison of the frameworks, approaches and overall implementation of policies and laws, this book acts as a tool to influence and inform further efforts in conservation and sustainable use of marine resources, particularly fisheries, in these countries and others in Latin America and the Caribbean. A broad range of issues are covered including food security, tourism, fisheries, oil and mineral extraction from the seabed, wind power, coastal and marine pollution and endangered species conservation. The chapters compare how each country addresses these issues from an institutional, legal and policy perspective. The book concludes by identifying common lessons, reoccurring challenges and develops scalable recommendations applicable to the case study countries and the wider region. The book will be of interest to advanced students, policy makers and researchers in marine and fishery science, law and policy.

Transdisciplinary Marine Research
Author: Sílvia Gómez
Publisher: Taylor & Francis
ISBN: 1000836614
Category : Nature
Languages : en
Pages : 291
Book Description
Drawing on the expertise of marine researchers from both the natural and social sciences, this book examines how we, as both scientists and societies, can return to a sustainable co-existence with the ocean and use the tools of transdisciplinarity to bring together the diverse forms of knowledge needed to achieve this important task. The marine sciences play a vital role in producing and providing the knowledge needed for a transition towards ocean sustainability. With a multitude of actors involved in using, exploiting, and safeguarding the seas, however, this task cannot be solved by science alone. Transdisciplinary research is needed, bringing together scientists and all other actors of society to jointly co-produce the knowledge and innovations that we so urgently need. In this context, this book examines and answers key questions at the forefront of transdisciplinary marine research: How can we provide approaches that integrate marine biodiversity and social systems in an appropriate relationship? What methodologies are most suitable to engage stakeholders in participatory processes providing new knowledge and tools for co-designing solutions with balanced socio-ecological embeddedness? How do we best integrate scientific with lay and local knowledge, and how are diverse knowledges valued in engagement activities? How can we reconcile socio-economic activities and the often divergent values attached to them to provide ethical principles for fair and equitable policy decisions? The book addresses these questions by combining an array of chapters about new theoretical approaches to transdisciplinary marine research, methodological considerations, as well as case studies from the nexus of the research and practices of engagement with a variety of stakeholder groups across the globe. This book will be of great interest to students and scholars studying marine science and ocean research across a wide range of disciplines, including marine biology, environmental governance and policy, ocean resource management, oceanography, environmental anthropology, human geography and sustainability. It will also be of interest to those looking to build a greater understanding of transdisciplinary research and knowledge co-production, and practitioners working alongside academics. ‘Chapter 1 and Chapter 8 of this book is available for free in PDF format as Open Access from the individual product page at www.routledge.com.

Oceans and Society
Author: Ana K. Spalding
Publisher: Taylor & Francis
ISBN: 1000832821
Category : Nature
Languages : en
Pages : 259
Book Description
This unique textbook presents an introduction to the interdisciplinary field of marine studies, exploring the dynamic relationship between people and the marine environment. Emphasizing the human dimension of coastal and ocean issues, the book provides an innovative examination of the complex marine–human environment dynamics by drawing on social science and humanities approaches. Applying these interdisciplinary approaches, the textbook addresses key challenges facing the marine environment, including changing climate, fisheries, aquaculture, marine pollution, energy production, and management of areas beyond national jurisdiction. While leading with a human dimension approach to these challenges, the chapters are all firmly grounded in foundational knowledge about coastal and ocean environments and processes. The textbook also includes examples of professional or academic areas of specialization within marine studies such as social and environmental justice, governance, global perspectives, traditional ecological knowledge and management, entrepreneurship, community development, conservation, and the blue economy. Ultimately, the book provides the first cohesive resource on marine studies to educate students, train interdisciplinary marine leaders, inspire new knowledge about people and the sea, generate innovative solutions for sustainable oceans, and build capacity for a new generation of marine-focused professionals. Oceans and Society is essential reading for students on marine studies courses, as well as those studying marine governance, policy, conservation, and law more broadly. It will also be of great interest to students, researchers, and professionals interested in applying interdisciplinary approaches to environmental challenges.

Fishing Europe's Troubled Waters
Author: David Symes
Publisher: Taylor & Francis
ISBN: 1000848302
Category : Nature
Languages : en
Pages : 193
Book Description
Spanning the last 50 years of fisheries policy in Europe, this book is the parting contribution and career-spanning reflection from one of Europe’s most renowned social scientists working in the field of fisheries management and policy. The last 50 years have without doubt been the most turbulent years in the history of North Atlantic fisheries – a turbulence brought about by the actions of fishers, scientists and above all politicians. It is a period of change that sees a radical redrawing of the political geography of fisheries, globalisation of trade, the development of fisheries management towards increasingly restrictive regulation, and declining fish stocks. The book explains why the bold but deeply flawed Common Fisheries Policy persistently failed to deliver its basic goal of sustainable fisheries. The spotlight falls on the monolithic, highly centralised, command and control nature of the Policy that strives to apply a universal ‘one size fits all’ approach, thus creating a governing system wholly unsuited to the system to be governed, out of kilter with preferred models of governance, and disconnected from the practical realities of fishing as a livelihood in a challenging environment. A final section on Brexit focuses on its halting progress from concept to reality, the implications for the fisheries sector and the fateful final negotiations with the EU over the fisheries question. Seeking to explain why the anticipated benefits for the UK industry failed to materialise, attention is drawn to the misplaced political hubris over regaining ‘sovereignty’ in areas like the North Sea. This book will be essential reading for students, scholars, professionals and policymakers working on fisheries, marine governance, natural resource management, environmental policy and the European Project.

This book is an ethnographic study of several coastal communities in the Kei Islands of eastern Indonesia. Central to Dr. Adhuri’s argument is an insistence that systems of local marine resource management cannot be studied on their own, in isolation from either the complex cultural and historical conditions that give impetus to community action or from the equally complex regional and national contexts within which such action is undertaken.
