Science for Ecosystem-based Management: Narragansett Bay in the 21st Century addresses the broad problem of coastal nutrient pollution. In the U.S., approximately two thirds of the coastal rivers and bays are moderately to severely degraded from nutrient pollution. However, debates continue about how large a problem nutrient pollution is and what actions to take, and since effective management requires decisions at a local scale, an in-depth case study can provide valuable guidance.Narragansett Bay is one of the best-studied estuaries in the world. Rhode Island has been developing regulatory and management actions to reduce nutrient inputs, particularly those of nitrogen, to the waters of Narragansett Bay. This book was developed in response to a symposium addressing this mandate with coastal/estuarine scientists and environmental management agency personnel. The contributors use long-term data sets to discuss the interactions among biological, ecological, chemical, and physical processes, and discuss what is known about nutrient inputs to the bay ecosystem, the impacts related to nutrient inputs, and how the ecosystem might respond to a sudden reduction in these inputs.

Fishery products are the world's most important source of animal protein, especially for the poor. Meeting the basic human needs for protein foods in the future will be a difficult challenge, especially as demand for fish has doubled since the 1950s. Realistically we can not expect to catch more food from the sea, so we must now turn to farming the waters, not just hunting them. The new challenge for planners is to accelerate aquaculture development and to plan for new production. As millions of people are moving from rural, inland areas to coastal cities we need to make urban areas not only centres of marketing and distribution, but also of production, particularly using recycled urban wastewater. This book on urban aquaculture includes papers from authors in the USA, Europe and Asia that review these emerging issues from the perspective of both developed and developing countries.
