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
This book examines the economic costs and benefits of the ecological restoration of estuaries, utilizing case studies from South Africa. Estuaries are important ecosystems from both an ecological and human perspective. Yet, in many parts of the world they are often degraded environments, facing threats from climate change, invasive species, fire and wastewater pollution. While the environmental benefits of restoring degraded environments are well discussed, this book specifically examines the economic benefits of doing so. It applies a cost-benefit analysis, which focuses on a range of key ecosystem services, including human health, fishing value, recreational value and property value. The book utlizes three detailed studies of the Swartkops estuary, the Great Brak estuary and the Knysna estuary in South Africa, but also draws out lessons that can be applied to coastal environments across the world. Overall, this book demonstrates that ecological restoration does pay and that the value of additional ecosystem services gained through restoration far exceeds the costs associated with this restoration process. This book will be of great interest to students and scholars of environmental management and restoration, ecological economics, ecosystem services and environmental conservation.
