Book Description
Norwegian spring-spawning herring and Northeast Arctic cod are two of the largest and commercially most important fish stocks in the North Atlantic. Both these stocks have their spawning fields along the Norwegian coast and they have been the major target species for Norwegian fisheries for a millennium. They are also among the few fish stocks in the world which have been systematically investigated and monitored for more than a century. The scientific results, arrived at early in the 20th century for these two stocks, formed the basis for much of the development in international fisheries science later on. This book describes how fisheries, fisheries science, and management for Norwegian spring-spawning herring and Northeast Arctic cod developed during the 20th century. Over time, both populations developed serious decline in stock size and yield due to overfishing. The herring stock was in a state of collapse for about 20 years. Management measures that were then introduced permitted both stocks to recover in the 1990s. The contributors to the book have all been working as fisheries scientists at the Institute of Marine Research in Bergen.

Book Description
This book has nine chapters on Aquaculture Wetland Ecosystem Services Approach and Climate Change Adaptation, which explain how different aquaculture systems could maximize the benefits that society receives from both aquaculture production and the ecosystem services provided by wetland ecosystems. Sustainable development of aquaculture must take into account the societal value of ecosystem services for an efficient and environmentally sound production of food. Although some issues regarding the potential benefits and implementation of sustainable aquaculture remain, the consideration of food security and minimizing ecosystem impacts suggest that the time has come to take action. If we can efficiently farm the land, why can't we farm more the sea and inland waters?

Book Description
This collective book is a multidisciplinary approach on a key-topic for our common future: overfishing. The focus is addressed to the "Atlantic World", considering the main oceanic geography in which this problem born in the early 20th century. The volume offers a wide range of contributions from experts on the topic covering the most relevant areas of the Atlantic and explaining important case studies on overfishing recent history. Written in a historical perspective, the book looks for institutional regulatory solutions based on multilateral solutions and scientific advising. Founders thought on the topic and the understanding’s evolution of the overfishing problem are mainly considered. This book is an accessible synthesis on overfishing history especially recommended for social scientists, historians, biologists, decision-makers and committed citizens.

Book Description
As world natural resources diminish and the necessity of protecting our environment becomes critical, the need for efficient marine management increases. However, marine boundaries are not easily defined and in disputed areas the prospect of sound management is difficult. The Barents Sea is a perfect example of this. Despite being rich in living resources, the area remains under developed and its eco-system is under growing threat. This inefficient management is largely due to two legal disputes, both of which involve the USSR. Marine Management in Disputed Areas examines the complicated management of the Barents Sea, as well as offering a detailed analysis of two highly sensitive legal disputes.

Book Description
The Arctic has often been seen as a natural area, or even a “wilderness”, where mainly indigenous and subsistence activities have been prominent. Contrary to this, the present volume highlights the very long historical development of resource use systems in northern Europe, across multiple actors and multiple levels, and including varying population groups. The book takes a past-present-future perspective that illustrates the paths to institutional emergence, change or persistence over time. It also illustrates how institutions may themselves drive changes, through a focus on resource use cases in northern Europe. This volume demonstrates that understanding “northern” issues is less about understanding sets of geophysical, climatological or environmental conditions than about understanding social and institutional structures. Understanding these trajectories into the future is seen as a key way of understanding what responses to future change may be likely and what the institutions are that will shape, limit or enable our responses to climate change. This book will be of great use to scholars and graduates in the fields of Arctic and northern-region politics, and to researchers of resource use and climate change with a focus on vulnerability, social vulnerability, adaptation and mitigation.

Book Description
Oceans and Aquatic Ecosystems theme is a component of Encyclopedia of Natural Resources Policy and Management, in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The theme guides the reader through various pathways followed by surface water on earth. It describes the dominant processes that govern how organisms interact with water and with each other, and how they in turn can modify water properties. This knowledge is important for humanity. Indeed, only by understanding our actions impacts upon water, and the animals and plants living in it, can we learn to exploit water, marine and fresh-water habitats and the living organisms, without destroying the resources on which our livelihood and very survival depend. The Theme on Oceans and Aquatic Ecosystems discusses matters of great relevance to our world such as: Freshwater Wetland Resources and Biology; Problems, Restoration and Conservation of Lakes and Rivers; Coastal Regions; The Oceans and Seas; Oceanic Islands These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Book Description
Oceanography and Marine Biology: An Annual Review remains one of the most cited sources in marine science and oceanography. The ever increasing interest in work in oceanography and marine biology and its relevance to global environmental issues, especially global climate change and its impacts, creates a demand for authoritative reviews summarizing the results of recent research. This volume covers topics that include resting cysts from coastal marine plankton, facilitation cascades in marine ecosystems, and the way that human activities are rapidly altering the sensory landscape and behaviour of marine animals. For more than 50 years, OMBAR has been an essential reference for research workers and students in all fields of marine science. From Volume 57 a new international Editorial Board ensures global relevance, with editors from the UK, Ireland, Canada, Australia and Singapore. The series volumes find a place in the libraries of not only marine laboratories and institutes, but also universities. Previous volume Impact Factors include: Volume 53, 4.545. Volume 54, 7.000. Volume 55, 5.071. Guidelines for contributors, including information on illustration requirements, can be downloaded on the Downloads/Updates tab on the volume's CRC Press webpage.

Book Description
Throughout the twentieth century, glaciologists and geophysicists from Denmark, Norway and Sweden made important scientific contributions across the Arctic and Antarctic. This research was of acute security and policy interest during the Cold War, as knowledge of the polar regions assumed military importance. But scientists also helped make the polar regions Nordic spaces in a cultural and political sense, with scientists from Norden punching far above their weight in terms of population, geographical size or economic activity. This volume presents an image of Norden that stretches far beyond its conventional limits, covering a vast area in the North Atlantic and the Arctic Sea, as well as parts of Antarctica. Rich in resources, scarce in population, but critically important in global and regional geopolitics, these spaces were contested by major powers such as Russia, the United States, Canada and, in the Antarctic, Argentina, Australia, South Africa and others. The empirical focus on Danish, Norwegian and Swedish influence in the polar regions during the twentieth century embraces a diverse array of themes, from the role of science in policy and diplomacy to the tensions between nationalism and internationalism, with clear relevance to the important role science plays in contemporary discussions about Nordic engagement with the polar regions.
