Book Description
This report is the result of an examination of the feasibility of isolating contaminated dredged material on the abyssal seafloor. The focus is on the technical and environmental factors that constrain the considerations of feasibility. The sources of the materials are assumed to be in U.S. coastal waters. A thorough conceptual design of a dredging to abyssal deposition system is analyzed with regard to each subsystem and to the entire operational concept. These subsystems include: (1) a low leakage dredge, (2) equipment for material handling and loading into geosynthetic fabric containers (GFCs), (3) the barge for transport and navigation, and (4) the subsystem for releasing the GFCs to sink to the abyssal seafloor isolation site. Particular consideration is given to the exclusion of dredged material from the ocean's productive zone in the upper 1000 m; this exclusion requires highly stable, reliable navigation and seakeeping by the barge transporter and control of the configuration of GFCs within it. New theoretical models and previous empirical results are used to predict GFC motion through the water column and response to impact on the abyssal seafloor, including the case of potential release of contaminated, turbid water at impact. A geochemical model of the temporal and spatial evolution of the post-deposition geochemistry of the water column, the GFC contents and the sediments below is developed and analyzed; the results show that release of metals into the ocean waters would be insignificant. A model of the biological impacts of the introduction of dredged material in the abyssal environment is used to infer that: (1) biological diversity in the vicinity of the deposition site will be diminished, (2) biomass will be increased by dominance of a few fast growing, opportunistic benthic species, and (3) concentrations of trace elements and organic contgt\h1

Book Description
This is a wonderful book rich in empirical detail, full of theoretical insights, offering hope in a bleak world, altogether inspiring. . . a tremendous achievement of having helped to create the disciplines of ecological economics and political ecology, bringing them alive in this book, and making their insights available to the developing worldwide movement for environmental justice. Pat Devine, Environmental Values Any book by the ecological economist Joan Martinez-Alier is a Big Publishing Event. . . this is a book by a writer who loves his subject, knows it well, respects its history, and is driven by the desire to do justice. These are qualities enough to send you to the bookshop or the library in search of The Environmentalism of the Poor. Andrew Dobson, Environment Politics The book is a worthy and in-depth contribution to debates about political ecology and ecological economics. It should be read by all environmental and ecological economists who wish to make their analysis more relevant. Tim Forsyth, Progress in Development Studies A marvellous combination of insight, research and activism. . . A must-read for policymakers, practitioners and academics alike, and for anyone concerned with sustainable development, environmentalism or poverty alleviation. Human Ecology Journal . . . one of the most important environmental books to have been published recently. Martinez-Alier integrates two of the most significant areas of environmental theory political ecology and ecological economics. Eurig Scandrett, Friends of the Earth Scotland The book has three main strengths: its bibliography, which is extensive; the global perspective on the environmental movement and the relationship with poverty; and the general theme of this interdisciplinary work, which is not so much to provide new information, but to consider the existing information in a new light. Martinez-Alier is to be commended for taking such a step in the literature . . . the writing style is extremely approachable . . . Recommended. B.J. Peterson, Choice [Joan] Martinez-Alier combines the honest discipline of a scholar with the passionate energy of an activist. The result, The Environmentalism of the Poor, is highly recommended! Herman E. Daly, University of Maryland, College Park, US The Environmentalism of the Poor has the explicit intention of helping to establish two emerging fields of study political ecology and ecological economics whilst also investigating the relations between them. The book analyses several manifestations of the growing environmental justice movement , and also of popular environmentalism and the environmentalism of the poor , which will be seen in the coming decades as driving forces in the process to achieve an ecologically sustainable society. The author studies, in detail, many ecological distribution conflicts in history and at present, in urban and rural settings, showing how poor people often favour resource conservation. The environment is thus not so much a luxury of the rich as a necessity of the poor. It concludes with the fundamental questions: who has the right to impose a language of valuation and who has the power to simplify complexity? Joan Martinez-Alier combines the study of ecological conflicts and the study of environmental valuation in a totally original approach that will appeal to a wide cross-section of academics, ecologists and environmentalists.
