Book Description
This book analyses the risky behavior of farmers in the Mekong Delta, Vietnam, in their shift from rice to shrimp farming, as well as the role of social capital in these farmers’ economic activities. Emphasizing the rationality of the market does not fully explain the nature of farmers’ economic behavior. Therefore, this book explores farmers’ risk mitigation and dispersion, so as to provide a systematic outlook on the issue. It finds that “food security” and “subsistence margin” influence farmers’ behavior to some extent. In the context of current social relations, farmers do not completely avoid risks, but they have different risk-taking strategies. As the book shows, social reciprocity in terms of capital, labor, and land allows poor farmers to participate in shrimp farming in a risky manner.

Book Description
This book focuses on the challenges people face in managing agricultural crops, aquaculture, fisheries and related ecosystems in inland areas of coastal zones in the tropics of Asia, Africa, Australia and South America. These challenges can create conflicts in the use of natural resources between different stakeholders. Through many case studies, the book discusses the nature of the conflicts and identifies what is known and not known about how to manage them. For example, some case studies relate to the trade-offs between enhancing agricultural production by constructing embankments to keep out saline water and maintaining not only the variety of rural livelihoods but also brackish aquatic biodiversity. Other case studies provide the lessons learnt from the conversion of mangrove forests to shrimp farms.

Book Description
The 2020 edition of The State of World Fisheries and Aquaculture has a particular focus on sustainability. This reflects a number of specific considerations. First, 2020 marks the twenty-fifth anniversary of the Code of Conduct for Responsible Fisheries (the Code). Second, several Sustainable Development Goal indicators mature in 2020. Third, FAO hosted the International Symposium on Fisheries Sustainability in late 2019, and fourth, 2020 sees the finalization of specific FAO guidelines on sustainable aquaculture growth, and on social sustainability along value chains. While Part 1 retains the format of previous editions, the structure of the rest of the publication has been revised. Part 2 opens with a special section marking the twenty fifth anniversary of the Code. It also focuses on issues coming to the fore, in particular, those related to Sustainable Development Goal 14 and its indicators for which FAO is the “custodian” agency. In addition, Part 2 covers various aspects of fisheries and aquaculture sustainability. The topics discussed range widely, from data and information systems to ocean pollution, product legality, user rights and climate change adaptation. Part 3 now forms the final part of the publication, covering projections and emerging issues such as new technologies and aquaculture biosecurity. It concludes by outlining steps towards a new vision for capture fisheries. The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to-date information to a wide audience – policymakers, managers, scientists, stakeholders and indeed everyone interested in the fisheries and aquaculture sector.

Book Description
Published in Cooperation with THE WORLD AQUACULTURE SOCIETY Shrimp is the most important commodity, by value, in the international seafood trade. The shrimp industry has grown exponentially in the last decades, and growth is expected to continue for years to come. For future success in the shrimp industry, shrimp farmers and aquaculture scientists will find a thorough knowledge of the economics, market, and trade as important as an understanding of disease management or husbandry. Shrimp Culture: Economics, Market, and Trade brings together recent findings of researchers from around the world working in various aspects of the economics of shrimp farming. This volume covers all major aspects of the economics, trade, and markets for shrimp worldwide, with chapters written by experts from major consuming countries such as the U.S.A. and major providers such as China, Thailand and Brazil. The book has been carefully edited by PingSun Leung and Carole Engle, both well known and respected internationally for their work in this area. Shrimp Culture is an essential purchase for everyone involved in this massive industry across the globe.

Book Description
Systems studied in environmental science, due to their structure and the heterogeneity of the entities composing them, often exhibit complex dynamics that can only be captured by hybrid modeling approaches. While several concurrent definitions of “hybrid modeling” can be found in the literature, it is defined here broadly as the approach consisting in coupling existing modelling paradigms to achieve a more accurate or efficient representation of systems. The need for hybrid models generally arises from the necessity to overcome the limitation of a single modeling technique in terms of structural flexibility, capabilities, or computational efficiency. This book brings together experts in the field of hybrid modelling to demonstrate how this approach can address the challenge of representing the complexity of natural systems. Chapters cover applied examples as well as modeling methodology.

Book Description
INVESTIGATIVE REPORTERS & EDITORS Book Award, Finalist 2014 "Greenberg’s breezy, engaging style weaves history, politics, environmental policy, and marine biology." --New Yorker From the acclaimed author of Four Fish and The Omega Principle, Paul Greenberg uncovers the tragic unraveling of the nation’s seafood supply—telling the surprising story of why Americans stopped eating from their own waters in American Catch In 2005, the United States imported five billion pounds of seafood, nearly double what we imported twenty years earlier. Bizarrely, during that same period, our seafood exports quadrupled. American Catch examines New York oysters, Gulf shrimp, and Alaskan salmon to reveal how it came to be that 91 percent of the seafood Americans eat is foreign. In the 1920s, the average New Yorker ate six hundred local oysters a year. Today, the only edible oysters lie outside city limits. Following the trail of environmental desecration, Greenberg comes to view the New York City oyster as a reminder of what is lost when local waters are not valued as a food source. Farther south, a different catastrophe threatens another seafood-rich environment. When Greenberg visits the Gulf of Mexico, he arrives expecting to learn of the Deepwater Horizon oil spill’s lingering effects on shrimpers, but instead finds that the more immediate threat to business comes from overseas. Asian-farmed shrimp—cheap, abundant, and a perfect vehicle for the frying and sauces Americans love—have flooded the American market. Finally, Greenberg visits Bristol Bay, Alaska, home to the biggest wild sockeye salmon run left in the world. A pristine, productive fishery, Bristol Bay is now at great risk: The proposed Pebble Mine project could under¬mine the very spawning grounds that make this great run possible. In his search to discover why this pre¬cious renewable resource isn’t better protected, Green¬berg encounters a shocking truth: the great majority of Alaskan salmon is sent out of the country, much of it to Asia. Sockeye salmon is one of the most nutritionally dense animal proteins on the planet, yet Americans are shipping it abroad. Despite the challenges, hope abounds. In New York, Greenberg connects an oyster restoration project with a vision for how the bivalves might save the city from rising tides. In the Gulf, shrimpers band together to offer local catch direct to consumers. And in Bristol Bay, fishermen, environmentalists, and local Alaskans gather to roadblock Pebble Mine. With American Catch, Paul Greenberg proposes a way to break the current destructive patterns of consumption and return American catch back to American eaters. The Washington Post: "Americans need to eat more American seafood. It’s a point [Greenberg] makes compellingly clear in his new book, American Catch: The Fight for our Local Seafood...Greenberg had at least one convert: me.” Jane Brody, New York Times “Excellent.” The Los Angeles Times “If this makes it sound like American Catch is another of those dry, haranguing issue-driven books that you read mostly out of obligation, you needn’t worry. While Greenberg has a firm grasp of the facts, he also has a storyteller’s knack for framing them in an entertaining way.” The Guardian (UK) “A wonderful new book” Tom Colicchio: "This is on the top of my summer reading list. A Fast Food Nation for fish.”

Book Description
The Mekong Delta of Vietnam is one of the most productive agricultural areas in the world. The Mekong River fans out over an area of about 40,000 sq kilometers and over the course of many millennia has produced a region of fertile alluvial soils and constant flows of energy. Today about a fourth of the Delta is under rice cultivation, making this area one of the premier rice granaries in the world. The Delta has always proven a difficult environment to manipulate, however, and because of population pressures, increasing acidification of soils, and changes in the Mekong’s flow, environmental problems have intensified. The changing way in which the region has been linked to larger flows of commodities and capital over time has also had an impact on the region: For example, its re-emergence in recent decades as a major rice-exporting area has linked it inextricably to global markets and their vicissitudes. And most recently, the potential for sea level increases because of global warming has added a new threat. Because most of the region is on average only a few meters above sea level and because any increase of sea level will change the complex relationship between tides and down-river water flow, the Mekong Delta is one of the areas in the world most vulnerable to the effects of climate change. How governmental policy and resident populations have in the past and will in coming decades adapt to climate change as well as several other emerging or ongoing environmental and economic problems is the focus of this collection.
