Book Description
Despite advances in modeling, such as graphical user interfaces, the use of GIS layers, and databases for developing input files, the approaches to modeling phosphorus (P) have not changed since their initial development in the 1980s. Current understanding of P processes has evolved and this new information needs to be incorporated into the current models. Filling this need, Modeling Phosphorus in the Environment describes basic approaches to modeling P, how the current models implement these approaches, and ways to improve them. The book sets the scene with a review of general approaches to modeling runoff and erosion, P in runoff, leaching of P, stream processes that affect P, and an examination of the important issue of model uncertainty. It describes state-of-the-science watershed-scale P transport models including dynamic semi-disturbed models, models of intermediate complexity, and two lumped models. Phosphorus Indexes (PIs) represent one end of the modeling spectrum and the book takes a comprehensive look at PIs developed in each state, and illustrates some of the problems encountered when incorporating PIs into farm-scale manure management software. The book discusses monitoring data, which is critical for calibrating models, and concludes with suggestions for improving the modeling of P. From researching mechanisms to applying regulations, the uses of phosphorus models have increased as our knowledge of the effects of phosphorus in the environment has increased. Drawing on contributions from experts, the book gives you the tools to select the model that best fits your needs.

Book Description
Nanoscale science and computing is becoming a major research area as today's scientists try to understand the processes of natural and biomolecular computing. The field is concerned with the architectures and design of molecular self-assembly, nanostructures and molecular devices, and with understanding and exploiting the computational processes of biomolecules in nature. This book offers a unique and authoritative perspective on current research in nanoscale science, engineering and computing. Leading researchers cover the topics of DNA self-assembly in two-dimensional arrays and three-dimensional structures, molecular motors, DNA word design, molecular electronics, gene assembly, surface layer protein assembly, and membrane computing. The book is suitable for academic and industrial scientists and engineers working in nanoscale science, in particular researchers engaged with the idea of computing at a molecular level.

Book Description
In recent years, water resource management in the United States has begun a shift away from top-down, government agency-directed decision processes toward a collaborative approach of negotiation and problem solving. Rather than focusing on specific pollution sources or specific areas within a watershed, this new process considers the watershed as a whole, seeking solutions to an interrelated set of social, economic, and environmental problems. Decision making involves face-to-face negotiations among a variety of stakeholders, including federal, state, and local agencies, landowners, environmentalists, industries, and researchers. Swimming Upstream analyzes the collaborative approach by providing a historical overview of watershed management in the United States and a normative and empirical conceptual framework for understanding and evaluating the process. The bulk of the book looks at a variety of collaborative watershed planning projects across the country. It first examines the applications of relatively short-term collaborative strategies in Oklahoma and Texas, exploring issues of trust and legitimacy. It then analyzes factors affecting the success of relatively long-term collaborative partnerships in the National Estuary Program and in 76 watersheds in Washington and California. Bringing analytical rigor to a field that has been dominated by practitioners' descriptive accounts, Swimming Upstream makes a vital contribution to public policy, public administration, and environmental management.

Book Description
Innovative Strategies for Managing Weeds in an Environmentally Protective Manner Successfully meeting the challenge of providing weed control without relying on dangerous chemicals that endanger the ecosystem or human lives, this compendium focuses on management strategies that reduce herbicidal usage, restore ecological balance, and increase food production. It also provides new insights and approaches for weed scientists, agronomists, agriculturists, horticulturists, farmers, and extentionists, as well as teachers and students. In the Handbook of Sustainable Weed Management, experts from Asia, Europe, North America, and Australia organize in one resource information related to weeds and their management from different ecosystems around the world that has been until now been scattered throughout the literature.. The text captures the multifaceted impacts of and approaches to managing weeds from field, farm, landscape, regional, and global perspectives. Generously illustrated with tables and figures, this book not only describes the various techniques for weed management but shows you what methods work best in a given region, or in response to a specific, invasive weed or invaded crop. Covering the full scope of modern weed science the handbook examines different aspects of weed management, including— • Cultural practices • Cover crops • Crop rotation designs • Potential of herbicide resistant crops • Bioherbicides • Allelopathy • Microorganisms • Integrated weed management In spite of advancement in technologies and procedures, weeds continue to pose a major ecological and economical threat to agriculture. Handbook of Sustainable Weed Management takes a broad view of weeds as a part of an agricultural system composed of interacting production, environmental, biological, economic, and social components all working together to find balance. This comprehensive book is a vital addition to the debate over how global weed management is changing in the 21st century. Also available in soft cover
