Aquaculture is the farming of aquatic organisms, principally fish, molluscs, crustaceans and marine algae. It has seen phenomenal worldwide growth in the past fifty years and many people view it as the best solution for the provision of high quality protein to feed the world's growing population, particularly with the rapid decline in wild marine fish populations. Aquaculture now contributes approximately one third of the world's fish production, and has increased by about eight per cent annually over the last thirty years, while wild capture fishery production has remained static. Focused on developing more sustainable aquaculture practices, this book provides an ideal advanced-level textbook. It is based on extensive evidence and knowledge of best practices, with guidance on appropriate adaptation and uptake in a variety of environmental, geographic, socio-economic and political settings. The author concentrates on low-impact aquaculture systems and approaches, which have minimal adverse effects on the environment. He also emphasizes socially responsible and equitable aquaculture development; to enhance the natural resource base and livelihoods. Drawing on a range of case-studies from around the world, the objective is to show where progress in terms of developing ecologically sound and socially responsible forms of aquaculture has been made. A tool-box of approaches to support widespread adoption and appropriate adaptation of regenerating aquaculture strategies is provided, ensuring the book will have practical relevance for both students and professionals.

In this second edition of The Sociology of Food and Agriculture, students are provided with a substantially revised and updated introductory text to this emergent field. The book begins with the recent development of agriculture under capitalism and neo-liberal regimes, and the transformation of farming and peasant agriculture from a small-scale, family-run way of life to a globalized system. Topics such as the global hunger and obesity challenges, GM foods, and international trade and subsidies are assessed as part of the world food economy. The final section concentrates on themes of sustainability, food security, and food sovereignty. The book concludes on a positive note, examining alternative agri-food movements aimed at changing foodscapes at levels from the local to the global. With increased coverage of the financialization of food, food and culture, gender, ethnicity and justice, food security, and food sovereignty, the book is perfect for students with little or no background in sociology and is also suitable for more advanced courses as a comprehensive primer. All chapters include learning objectives, suggested discussion questions, and recommendations for further reading to aid student learning.

Depolarizing Food and Agriculture

Many issues in food and agriculture are portrayed as increasingly polarized. These include industrial vs. sustainable agriculture, conventional vs. organic production methods, and global vs. local food sourcing, to name only three. This book addresses the origins, validity, consequences, and potential resolution of these and other divergences. Political and legal actions have resulted in significant monetary and psycho-social costs for groups on both sides of these divides. Rhetoric on many issues has caused misinformation and confusion among consumers, who are unsure about the impact of their food choices on nutrition, health, the environment, animal welfare, and hunger. In some cases distrust has intensified to embitterment on both sides of many issues, and even to violence. The book uses economic principles to help readers better understand the divisiveness that prevails in the agricultural production, food processing and food retailing industries. The authors propose solutions to promote resolution and depolarization between advocates with seemingly irreconcilable differences. A multifaceted, diverse, but targeted approach to food production and consumption is suggested to promote social well-being, and reduce or eliminate misinformation, anxiety, transaction costs and hunger.

Was wissen wir heute über die natürliche Produktivität der Auwälder an großen Flüssen vor der Regulierung und über deren ehemalige Funktion als Rohstoffquelle für erneuerbare Energie? Können wir aus einer historischen Rekonstruktion der ehemals verfügbaren Holzressourcen Rückschlüsse für ein nachhaltiges Ressourcenmanagement ziehen? Die Beantwortung dieser Fragen war Ziel des Forschungsprojekts „Genug Holz für Stadt und Fluss? - Wiens Holzressourcen in dynamischen Donau-Auen“. Am Beispiel der Wiener Donau-Flusslandschaft vor der Regulierung 1820 - 1830 untersuchte ein interdisziplinäres Team bestehend aus Flussmorphologen, Gewässer-, Vegetations- und Forstökologen sowie Umwelthistorikerinnen drei zentrale Themenkreise: (1) Flussmorphologisch-forstökologische Standortsbedingungen und natürliches Potenzial der dynamischen Donau-Auen vor der Regulierung Holzressourcen zu produzieren, (2) Historischer Umgang einer ehemals biomassebasierten Gesellschaft mit lokal verfügbaren Holzressourcen in Wien, (3) Zukünftige Entwicklungsmöglichkeiten von Donau-Auwäldern unter Berücksichtigung ökologisch-naturschutzfachlicher Ziele und forstwirtschaftlicher Anforderungen für die Produktion erneuerbarer Energieressourcen. Neben naturwissenschaftlichen Erkenntnissen für eine nachhaltige Nutzung naturnaher, teilweise „redynamisierter“ Auwälder lieferte das Forschungsprojekt auch neue Beiträge zur Wiener Stadtgeschichte und zur historischen Veränderung der Donau-Flusslandschaft.
