Book Description
'The Sunken Billions: The Economic Justification for Fisheries Reform' shows the difference between the potential and actual net economic benefits from marine fisheries is about $50 billion per year, or some $2 trillion over the last three decades. If fish stocks were rebuilt, the current marine catch could be achieved with approximately half the current global fishing effort. This illustrates the massive overcapacity of the global fleet. The excess competition for the limited fish resources results in declining productivity, economic inefficiency, and depressed fisher incomes. The focus on the deteriorating biological health of world fisheries has tended to obscure their equally critical economic health. Achieving sustainable fisheries presents challenges not only of biology and ecology, but also of managing political and economic processes and replacing pernicious incentives with those that foster improved governance and responsible stewardship. Improved governance of marine fisheries could regain a substantial part of this annual economic loss and contribute to economic growth. Fisheries governance reform is a long-term process requiring political will and consensus vision, built through broad stakeholder dialogue. Reforms will require investment in good governance, including strengthening marine tenure systems and reducing illegal fishing and harmful subsidies. Realizing the potential economic benefits of fisheries means reducing fishing effort and capacity. To offset the associated social adjustment costs, successful reforms should provide for social safety nets and alternative economic opportunities for affected communities.

Book Description
Women make up the vast majority of activists and organizers of grassroots movements fighting against environmental ills that threaten poor and people of color communities. [This] collection of essays ... pays tribute to the ... contributions women have made in these endeavors. The writers offer varied examples of environmental justice issues such as children's environmental-health campaigns, cancer research, AIDS/HIV activism, the Environmental Genome Project, and popular culture, among many others. Each one focuses on gender and sexuality as crucial factors in women's or gay men's activism and applies environmental justice principles to related struggles for sexual justice. Drawing on a wide variety of disciplinary perspectives, the contributors offer multiple vantage points on gender, sexuality, and activism.-Back cover.

Book Description
Do environmental problems and processes produce violence? Current U.S. policy about environmental conflict and scholarly work on environmental security assume direct causal links between population growth, resource scarcity, and violence. This belief, a staple of governmental decision-making during both Clinton administrations and widely held in the environmental security field, depends on particular assumptions about the nature of the state, the role of population growth, and the causes of environmental degradation.The conventional understanding of environmental security, and its assumptions about the relation between violence and the environment, are challenged and refuted in Violent Environments. Chapters by geographers, historians, anthropologists, and sociologists include accounts of ethnic war in Indonesia, petro-violence in Nigeria and Ecuador, wildlife conservation in Tanzania, and "friendly fire" at Russia's nuclear weapons sites. Violent Environments portrays violence as a site-specific phenomenon rooted in local histories and societies, yet connected to larger processes of material transformation and power relations. The authors argue that specific resource environments, including tropical forests and oil reserves, and environmental processes (such as deforestation, conservation, or resource abundance) are constituted by and in part constitute the political economy of access to and control over resources. Violent Environments demands new approaches to an international set of complex problems, powerfully arguing for deeper, more ethnographically informed analyses of the circumstances and processes that cause violence.

Book Description
Food engineering has become increasingly important in the food industry over the years, as food engineers play a key role in developing new food products and improved manufacturing processes. While other textbooks have covered some aspects of this emerging field, this is the first applications-oriented handbook to cover food engineering processes and manufacturing techniques. A major portion of Handbook of Food Engineering Practice is devoted to defining and explaining essential food operations such as pumping systems, food preservation, and sterilization, as well as freezing and drying. Membranes and evaporator systems and packaging materials and their properties are examined as well. The handbook provides information on how to design accelerated storage studies and determine the temperature tolerance of foods, both of which are important in predicting shelf life. The book also examines the importance of physical and rheological properties of foods, with a special look at the rheology of dough and the design of processing systems for the manufacture of dough. The final third of the book provides useful supporting material that applies to all of the previously discussed unit operations, including cost/profit analysis methods, simulation procedures, sanitary guidelines, and process controller design. The book also includes a survey of food chemistry, a critical area of science for food engineers.

Book Description
Polymers are permeable, whilst ceramics, glasses and metals are gener ally impermeable. This may seem a disadvantage in that polymeric containers may allow loss or contamination of their contents and aggressive substances such as water will diffuse into polymeric struc tures such as adhesive joints or fibre-reinforced composites and cause weakening. However, in some cases permeability is an advantage, and one particular area where this is so is in the use of polymers in drug delivery systems. Also, without permeable polymers, we would not enjoy the wide range of dyed fabrics used in clothing and furnishing. The fundamental reason for the permeability of polymers is their relatively high level of molecular motion, a factor which also leads to their high levels of creep in comparison with ceramics, glasses and metals. The aim of this volume is to examine some timely applied aspects of polymer permeability. In the first chapter basic issues in the mathema tics of diffusion are introduced, and this is followed by two chapters where the fundamental aspects of diffusion in polymers are presented. The following chapters, then, each examine some area of applied science where permeability is a key issue. Each chapter is reasonably self-contained and intended to be informative without frequent outside reference. This inevitably leads to some repetition, but it is hoped that this is not excessive.

Book Description
Trends in Food Engineering presents a wide vision of food engineering, with an emphasis on topics vital to the food industry today. The first section deals with physical and sensory properties of food. The emphasis in these chapters is on structure-function relationships, food rheology, and the correlations between physicochemical and sensory data. The second section, on advances in food processing, includes recent developments in minimal preservation and thermal and nonthermal processing of foods. The book concludes with current topics in food engineering, including applied biotechnology, food additives, and functional properties of proteins.
