Handbook Of Energy Utilization In Agriculture

The aim of this volume is to collect and present available data, both published and unpublished, on energy use in agriculture and forestry production. Energy analyses for some sciences such as ecology are not new, but their applications to agriculture started in 1973. These analyses have grown rapidly in number and complexity. This handbook is intended for agriculturalists and others concerned with energy use in crop, livestock, and forestry production.

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.

Adequate food supplies and a reasonable quality of life require energy~both noncommercial and commercial forms. This book is intended to be 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 $3/barrel to more than $40/barrel in 1981 and then back to less than a half of the peak price today. Commercial energy is expensive at any price for rural villagers in developing countries, and energy prices in these countries do not necessarily correspond with world prices. For example, diesel fuel prices in some developing countries have increased, while world oil prices have decreased. The rural sector of developing countries depends heavily on noncommercial energy sources. Availability of noncommercial energy is highly site-specific. This book deals extensively with noncommercial energy~its sources, the technologies for converting energy to more useful gaseous and liquid forms, and its ultimate end uses. Chapter I is an introduction and overview. It emphasizes the essential nature of energy to supplement the limited work output of human beings. Chapter II describes energy use in world agriculture with particular emphasis on fertilizer, machinery, and irrigation. It tabulates cereal grain yields as related to commercial energy input for various regions. Chapter III presents numerous national and regional illustrations of energy use.

This handbook provides a holistic overview of different aspects of energy management in agriculture with an orientation to address the sustainable development goals. It covers possible applications not only from a technical point of view, but also from economic, financial, social, regulatory, and political viewpoints. Agriculture is one of the most imperative sectors that contribute to the economy across different agro-ecologies of the universe with energy inputs in each stage of production, from making and applying chemicals to fueling tractors that lay seeds and harvest crops to electricity for animal housing facilities. The majority of agricultural research has focused on the use of input, production, and productivity, whereas rational energy budgeting and use remain an overlooked and likely underestimated segment, ignored so far while formulating agro-ecosystem framework. Energy management study is a new frontier of agriculture and is challenging duе to complex enterprises, spatial-temporal variability, exposure to pollution, and the predominant effect of the anthropogenic factor on ecology and environment. But it is worth taking the challenge considering the important prerequisite role of energy for sustainable development which has been evidenced from increasing research in recent times. Of recent origin, there are critical, in-depth studies around the globe assessing the capture and flow of energy in the ecosystem, which will help to develop a conceptual framework to incorporate this vital resource in the agriculture management template. This book is a state-of-the-art resource for a broad group of readers including a diversity of stakeholders and professionals in universities, public energy institutions, farmers and farming industry, public health and other relevant institutions, and the broader public as well.

World population growth and the related increase in the demand for food and other goods has intensified agricultural production throughout the world. Some of today's technologies are characterized by relatively low productivity and high consumption of energy resources. The Handbook of Research on Energy-Saving Technologies for Environmentally-Friendly Agricultural Development is a comprehensive research publication that provides insight into new technologies that create efficient and environmentally-friendly energy potential sufficient for the organization of industrial and social-economic activity in rural areas. Highlighting a variety of topics such as economic development, renewable energy, and climate change, this book is ideal for agricultural business executives, engineers, scientists, environmentalists, entrepreneurs, academicians, researchers, students, and those working in the agro-industrial and housing and communal services sectors.

Food and Energy Resources provides an understanding of the influence of energy, land, and water resources on food production. Future supplies of energy resources will have a major impact on the ability of humans to provide themselves with food. A better understanding of these issues will help society make sound choices and enable government leaders to develop and organize the necessary programs for the effective use of energy and food resources. The book begins with a discussion of the energy flow in the food system. This is followed by chapters that examine alternatives for the use of the external solar energy; the role of energy in world agriculture and food supply; the energy, land, and labor inputs in several major crop systems in northeastern China; and energy and food relationships in developing countries. Subsequent chapters deal with issues such as the use of renewable energy sources and the extent to which agricultural resources are used to produce food or fuel. This book will provide engineers, economists, agriculturists, geographers, ecologists, nutritionists, sociologists, and natural resource specialists a perspective that will help solve the problem of providing food for people while protecting natural resources.
