Download or read book The Economics of Agri Environmental Policy Volume II written by Sandra S. Batie and published by Routledge. This book was released on 2017-11-30 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume set collects key essays examining economic theory, methods, and issues salient to agri-environmental policy in the US and in Europe, as well as in other countries. The topics under discussion are arranged thematically and include theoretical, numerical and empirical works; all are grounded in policy and economics. The introduction to these volumes reviews the evolution of agri-environmental policies, with an important focus on the history of US policy and European agri-environmental policy. A key feature within this is the importance of the Environmental Protection Agency (EPA) in the US, particularly its move towards more 'market-based incentives' from the 1980s onwards. Within the European context, the effects of the CAP (Common Agricultural Policy) on agri-environmental programmes and schemes within the member states, are discussed. Significantly, the essays republished here have provided the knowledge base that has influenced further applied work, creating an influential impact on policy development.
Download or read book Soil Nitrogen Uses and Environmental Impacts written by Rattan Lal and published by CRC Press. This book was released on 2018-03-15 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen (N) is potentially one of the most complex elements on the Earth. It is necessary for all biological activity, but creates negative impacts on water and air quality. There is a balancing act between deficiency and surplus and the forms of N available further complicate our understanding of the dynamics. Biological fixation provides some plants with N supply while others are totally dependent upon N being available in the soil profile for the roots to extract. Nevertheless, the demand for N will increase because the human population with its increasing growth requires more protein and thus more N. Understanding the global N cycle is imperative to meeting current and future nitrogen demands while decreasing environmental impacts. This book discusses availability, production, and recycling of N in air, water, plants, and soils. It features information on N impacts to soil and water quality, management of N in agroecosystems, and techniques to maximize the use efficiency while minimizing the risks of leakage of reactive N into the environment. This volume in the Advances in Soil Science series is specifically devoted to availability, production, and recycling of N with impact on climate change and water quality, and management of N in agroecosystems in the context of maximizing the use efficiency and minimizing the risks of leakage of reactive N (NO-3, N¬2O) into the environment.

Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nitrogen in the Environment Sources Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
