Review of the EPA's Economic Analysis of Final Water Quality Standards for Nutrients for Lakes and Flowing Waters in Florida
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309254930
Category : Nature
Languages : en
Pages : 142
Book Description
The Environmental Protection Agency's estimate of the costs associated with implementing numeric nutrient criteria in Florida's waterways was significantly lower than many stakeholders expected. This discrepancy was due, in part, to the fact that the Environmental Protection Agency's analysis considered only the incremental cost of reducing nutrients in waters it considered "newly impaired" as a result of the new criteria-not the total cost of improving water quality in Florida. The incremental approach is appropriate for this type of assessment, but the Environmental Protection Agency's cost analysis would have been more accurate if it better described the differences between the new numeric criteria rule and the narrative rule it would replace, and how the differences affect the costs of implementing nutrient reductions over time, instead of at a fixed time point. Such an analysis would have more accurately described which pollutant sources, for example municipal wastewater treatment plants or agricultural operations, would bear the costs over time under the different rules and would have better illuminated the uncertainties in making such cost estimates.

Environment and Livelihoods in Tropical Coastal Zones
Author: International Rice Research InstitutePublisher: CABI
ISBN: 1845931076
Category : Science
Languages : en
Pages : 323
Book Description
This book focuses on the challenges people face in managing agricultural crops, aquaculture, fisheries and related ecosystems in inland areas of coastal zones in the tropics of Asia, Africa, Australia and South America. These challenges can create conflicts in the use of natural resources between different stakeholders. Through many case studies, the book discusses the nature of the conflicts and identifies what is known and not known about how to manage them. For example, some case studies relate to the trade-offs between enhancing agricultural production by constructing embankments to keep out saline water and maintaining not only the variety of rural livelihoods but also brackish aquatic biodiversity. Other case studies provide the lessons learnt from the conversion of mangrove forests to shrimp farms.
Toward Sustainable Agricultural Systems in the 21st Century

Book Description
In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.
