Agricultural Energetics

Fundamentals of energy and agriculture, Energy in nonindustrial food and production systems, Energy use in industrialized food production, Agricultural energy analysis, Energy and economics, Energy requirements for agricultural inputs, Evaluation of alternatives, Evaluation of specific practices, New sources of energy, The future.

This last volume of the Energy in World Agriculture series is in many ways the series' Alpha and its Omega. It addresses the broad issues related to the use of energy in agricultural production, and also characterizes and quantifies the energy involvements of many agricultural production technologies. It is a compilation of descriptive and analytical information and design principles and data of energy use in this field. A significant aspect is the relationship between energy and agricultural productivity, increased knowledge and resulting improved management of energy-consuming operations on the farm. Information provided here has not been published elsewhere before. Throughout the book are examples of the important role that energy inputs have played in increasing productivity of the world's agricultural systems. Together with a revived interest in energy for agricultural production due to increases in energy costs, this volume meets that interest with valuable information and insights.

Agriculture and Energy consists of the proceedings of a conference held at Washington University, St. Louis, Missouri, on June 17-19, 1976. The conference aims to bring together a broad spectrum of researchers concerned with obtaining a better understanding of the energy consumption by agriculture. These researchers are also concerned with developing ways to help food production adapt to occurring and anticipated resource availability problems. This book is organized into nine parts, separating the papers of the conference as chapters. It describes the quantity of energy consumed in particular production processes or in production at various levels of aggregation in the field of agriculture. It also dwells into the economic impacts of energy problems on agricultural production. It looks into the comparative economic and energy costs of the various methods for producing a specific product. Furthermore, this reference material discusses unconventional production methods that can reduce the need for fossil energy inputs by using renewable energy sources or recycling materials. Lastly, the implications of the energy situation for agricultural policy, both in the U.S. and in developing countries, are shown.

This book examines the characteristics and opportunities for farm energy in the northeast quadrant of the United States, with attention to energy use, strategic energy management, and energy production by solar, wind, biomass, and other means. Throughout, the distinct characteristics of the region and their impact on energy solutions are discussed, and the outlook for future energy strategies is considered. Farm energy production and use are topics of increasing interest, as the need for improved efficiency and the opportunity for sustainable energy production both drive agricultural enterprises to reduce energy use and pursue opportunities for renewable energy production and use on the farm. However, the unique regional characteristics of agriculture make it challenging to apply a single approach to all situations.

Energy and agriculture are both extremely broad subjects and their interactions - the subject of this book - cover almost the full spectrum of the agricultural sciences. Yet the subject is a relatively new one whose importance first received widespread recognition barely a decade ago, following the dramatic increase in oil prices during 1973. The impact of this increase was such as to promote a world-wide debate on the future direction that agriculture should take. This debate was, and is, of particular concern in countries where agriculture plays a leading role in economic and social development. During the last half century many national agricultural systems have been transformed from almost closed, self-sufficient systems with few locally produced inputs geared to satisfy local requirements, to intensive, open systems, utilizing large quantities of energy-rich inputs such as fossil fuel for manufactured agro-chemicals, water distribution and imported animal feedstuffs to produce a range of sophisticated products, often for export, which in tum require many energy-rich inputs for their marketing. This industrialization of agriculture has proved to be very successful in many respects and indeed was accepted as a general model for agricultural development allowing increased productivity and efficiency per unit land, labor and water, even in areas with limited natural resources.

Adequate food supplies and a reasonable quality of life require energy - both in commercial and non-commercial forms. This handbook is intended as a reference for individuals who want a comprehensive overview of energy for agriculture, many of whom are located in remote areas with limited library resources. The purpose is to put energy for agriculture in perspective by presenting numerous national and regional examples of energy usage.Since the early 1970s, world petroleum prices have fluctuated from US$3/barrel to more than US$40/barrel in 1981, and then back to one-third of the peak price today. Consequently, the rural sector depends heavily on non-commercial energy sources. Availability of such energy is highly site-specific. This handbook deals extensively with non-commercial energy - its sources, the technologies for converting energy to more useful gaseous and liquid forms, and its ultimate end-uses.Photographs, tables, line drawings and graphs are used extensively. Over 600 references are listed along with agency names and addresses for obtaining further information.
