Optimizing Nitrogen Management In Food And Energy Production And Environmental Protection

The production of food and energy interfere with the natural nitrogen cycle of the earth. Many of these changes are beneficial, while others are detrimental to societies and the environment. The changing nature of nitrogen in the global environment crosses scientific disciplines, geographical boundaries and political divisions and challenges the creative minds of natural and social scientists, economists, engineers, business leaders and planners. The papers in this book give readers a panoramic view of the changing nature of reactive nitrogen in the global environment, enabling them to make better choices about nitrogen management in food production and consumption, energy production and use, and environmental protection.

Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.

Livestock production systems are the result of an interaction between domestic animals and the environment, modulated by man, that dates back to Neolithic times. As a consequence of this interaction among the wide diversity of animal resources, natural habitats and population needs, very different farming systems have developed across the Mediterranean Basin. Understanding the mechanisms and effects of these relationships is key to design the farming systems best adapted to each condition, guaranteeing an adequate balance between target animal production and environmental outcomes provided by these systems. This is indeed a multidimensional topic, influenced by animal genetics, feeding resources, flock management, and economic and social aspects inside and outside the household. Therefore, this book focuses on the basis of the animal-environment interactions and the impact of human activities on the type and magnitude of these interactions. In this context, the issue of sustainability of livestock production is evaluated considering economic, social and environmental aspects. This book contributes to upgrade the state of the art in Mediterranean conditions, providing indicators and procedures of application across a wide range of systems, and hence of interest for researchers, students and professionals concerned with livestock production and the environment.

Bringing together a wealth of knowledge, Environmental Management Handbook, Second Edition, gives a comprehensive overview of environmental problems, their sources, their assessment, and their solutions. Through in-depth entries and a topical table of contents, readers will quickly find answers to questions about environmental problems and their corresponding management issues. This six-volume set is a reimagining of the award-winning Encyclopedia of Environmental Management, published in 2013, and features insights from more than 400 contributors, all experts in their field. The experience, evidence, methods, and models used in studying environmental management are presented here in six stand-alone volumes, arranged along the major environmental systems. Features The first handbook that demonstrates the key processes and provisions for enhancing environmental management Addresses new and cutting-edge topics on ecosystem services, resilience, sustainability, food–energy–water nexus, socio-ecological systems, and more Provides an excellent basic knowledge on environmental systems, explains how these systems function, and offers strategies on how to best manage them Includes the most important problems and solutions facing environmental management today In this fourth volume, Managing Water Resources and Hydrological Systems, the reader is introduced to the general concepts and processes of the hydrosphere with its water resources and hydrological systems. This volume serves as an excellent resource for finding basic knowledge on the hydrosphere systems and includes important problems and solutions that environmental managers face today. This book practically demonstrates the key processes, methods, and models used in studying environmental management.

This book will change the way we understand the future of our planet. It is both alarming and hopeful. James Gustave Spetch, renowned as a visionary environmentalist leader, warns that in spite of all the international negotiations and agreements of the past two decades, efforts to protect Earth's environment are not succeeding. Still, he says, the challenges are not insurmountable. He offers environmental threats around the world. The author explains why current approaches to critical global environmental problems Climate change, biodiversity loss, deterioration of marine environments, deforestation, water shortages, and others don't work now and won't work in the future. He provides a stinging critique of the failure of U.S. leadership and offers intriguing insights into why the U.S. has been able to address domestic environmental threats with some success while largely failing at the international level. Setting forth eight specific steps to a sustainable future, Speth convincingly argues that dramatically different and far-reaching actions by citizens and governments are now urgent. If ever a book could be described as essential , this is it.
