Book Description
All coastal states have ambitions for the development of their fisheries. Not only do fisheries play an important role in sustaining peoples' livelihoods, but also in many countries in the north and the south, fisheries are important for the national economy. Moreover, fisheries are part of the process of globalisation, which, for better or worse, means that fisheries issues and problems have implications that extend beyond the level of the nation state. Fisheries development: the institutional challenge is the result of a long-term research programme on fisheries in developing countries. The book explains how fisheries development strategies changed over the years, from simple ideas of modernising the production equipment (boats and gear) to complex programmes involving management and institution building. It highlights the role of the state and the community in resource management and the challenges offered by new concepts such as ecosystem management in a Third World setting. Book jacket.

Book Description
Jedes Jahr breiten sich invasive gebietsfremde Arten in neue Ökosysteme aus. Die von den Eindringlingen verursachten Auswirkungen können sich in kürzester Zeit bemerkbar machen und verheerend sein. Das Thema der invasiven gebietsfremden Arten ist umfassend, komplex und auf verschiedenen Ebenen von globaler Bedeutung. Verschärft wird es durch die Globalisierung der Weltwirtschaft und den zunehmenden Handel, durch den die natürlichen Barrieren für den Transfer von Arten durchbrochen werden. Invasive gebietsfremde Arten bedrohen die weltweite Nahrungsmittelversorgung, die Qualität und Verfügbarkeit von Trinkwasser sowie die Stromproduktion und -versorgung. Zusammen mit den zusätzlichen Risiken durch den globalen Klimawandel ist die weltweite Homogenisierung von Pflanzen, Tieren und Mikroben ein wesentlicher Faktor für den sich verschlechternden Gesundheitszustand der Ökosysteme und die nachlassenden Ökosystemdienstleistungen überall auf der Welt. Um dieser Entwicklung entgegenzuwirken, besteht die dringende Notwendigkeit einer einheitlichen Ausrichtung von Regierungen, Kulturen und Programmen und einer besseren grenzüberschreitenden Koordination. Nur so lassen sich die vielfältigen Bedrohungen durch invasive gebietsfremde Arten für die Umwelt, die Wirtschaft und die Gesundheit von Pflanzen und Tieren sowie insbesondere die menschliche Gesundheit effektiv bekämpfen. Dieses vierbändige Werk ist das erste, das einen umfassenden Satz nützlicher Materialien zu den zentralen Themen bereitstellt, um die gesamte globale Bedrohung durch invasive gebietsfremde Arten sowie die vielfältigen Probleme in verschiedenen Teilen der Welt deutlich zu machen, und es enthält Material, in dem potenziell replizierbare Lösungen zur Überwindung dieser Bedrohungen aufgezeigt werden. Das Werk betont die Bedrohung durch invasive gebietsfremde Arten auch im Sinne eines globalen ?Aufrufs zum Handeln?. Invasive Arten kennen keine Grenzen. Daher hoffen wir, dass wir durch die Zusammenstellung von Material, das unterschiedliche wissenschaftliche und gesellschaftliche Standpunkte aus aller Welt berücksichtigt, sowie durch die Vermittlung von Erkenntnissen und Beispielen zu einer Vielzahl damit zusammenhängender Themen das globale Bewusstsein stärken und einheitliche nationale Reaktionen auf die Bedrohung durch invasive gebietsfremde Arten fördern können.

Book Description
Upwelling systems are special places in the oceans where nutrient-enriched water is brought into the euphotic zone to fuel phytoplankton blooms that, via marine food-web interactions, create the world’s richest fish resources. This book introduces the reader to the interdisciplinary science of upwelling and provides a comprehensive overview of the world’s most productive marine ecosystems in the context of climate variability, climate change and human exploitation. This material presented is suitable for undergraduate and postgraduate study or just for anyone interested to learn about the creation of life in the oceans and how this is compromised by human activities.

Book Description
As we search urgently for a strategy of sustainable natural resource management, an international debate is brewing over destructive modern fishery methods. Namibia's Fisheries is a timely contribution to this discussion as it examines Namibia's Benguela upwelling system, an area that supports traditional and modern forms of fishery. This volume analyzes the Namibian experience in fishery management, featuring essays by researchers, Namibian fishery managers, and international specialists that cover a range of ecological and social issues. Namibia's Fisheries will be a valuable resource for researchers, conservationists, and students of fishery management.

Book Description
This is a book which examines much of what we know and also what we don’t know about the Benguela Current Large Marine Ecosystem and its inherent variability. Building on recent work and exciting findings about the predictability of the Benguela and other coastal upwelling ecosystems, the book takes a look towards the future and highlights the difficulty of making predictions in such a complex and variable region. The book illustrates what scientists and managers from developed and developing countries can achieve by working together, and it lays a solid base upon which to build wise management and ensure sustainable use of the ecosystem. Essential reading and a valuable reference work on the Benguela Current Large Marine Ecosystem Covers what we know about variability in the Benguela and its impacts Provides information on forecasting in the Benguela and offers insight in what is predictable and what is not Discusses key elements of a future integrated observing and forecasting system
