Book Description
This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Book Description
Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Book Description
The studies in this volume provide an ethnography of a plantation frontier in central Sarawak, Malaysian Borneo. Drawing on the expertise of both natural scientists and social scientists, the key focus is the process of commodification of nature that has turned the local landscape into anthropogenic tropical forests. Analysing the transformation of the space of mixed landscapes and multiethnic communities—driven by trade in forest products, logging and the cultivation of oil palm—the contributors explore the changing nature of the environment, multispecies interactions, and the metabolism between capitalism and nature. The project involved the collaboration of researchers specialising in anthropology, geography, Southeast Asian history, global history, area studies, political ecology, environmental economics, plant ecology, animal ecology, forest ecology, hydrology, ichthyology, geomorphology and life-cycle assessment. Collectively, the transdisciplinary research addresses a number of vital questions. How are material cycles and food webs altered as a result of large-scale land-use change? How have new commodity chains emerged while older ones have disappeared? What changes are associated with such shifts? What are the relationships among these three elements—commodity chains, material cycles and food webs? Attempts to answer these questions led the team to go beyond the dichotomy of society and nature as well as human and non-human. Rather, the research highlights complex relational entanglements of the two worlds, abruptly and forcibly connected by human-induced changes in an emergent and compelling resource frontier in maritime Southeast Asia.
