Since the publication of the first edition of Food, Energy, and Society, the world’s natural resources have become even more diminished due to the rapid expansion of the global human population. We are faced with dwindling food supplies in certain geographic areas, increasing pressure on energy resources, and the imminent extinction of many threatened species. In light of these major issues, this third edition presents an updated and expanded analysis on the interdependency of food, energy, water, land, and biological resources. Written by internationally renowned experts, the book includes new material on livestock production and energy use, the impacts of pesticides on the environment, and the conservation of biodiversity in agricultural, forestry, and marine systems. It also compares the energy inputs of crop production in developing and developed countries, covers the agricultural and environmental issues related to water resources, and details the threat of soil erosion to food and the environment. In addition, the book explores the very timely topics of solar energy, biomass systems, and ethanol production. Offering a startling glimpse at what our planet may become, this edition shows how to achieve the necessary balance between basic human needs and environmental resources and provides potential solutions to the host of problems we face today.

The petroleum age began about 150 years ago. Easily available energy has s- ported major advances in agriculture, industry, transportation, and indeed many diverse activities valued by humans. Now world petroleum and natural gas s- plies have peaked and their supplies will slowly decline over the next 40–50 years until depleted. Although small amounts of petroleum and natural gas will remain underground, it will be energetically and economically impossible to extract. In the United States, coal supplies could be available for as long as 40–50 years, depending on how rapidly coal is utilized as a replacement for petroleum and natural gas. Having been comfortable with the security provided by fossil energy, especially petroleum and natural gas, we appear to be slow to recognize the energy crisis in the U. S. and world. Serious energy conservation and research on viable renewable - ergy technologies are needed. Several renewable energy technologies already exist, but sound research is needed to improve their effectiveness and economics. Most of the renewable energy technologies are in uenced by geographic location and face problems of intermittent energy supply and storage. Most renewable technologies require extensive land; a few researchers have even suggested that one-half of all land biomass could be harvested in order to supply the U. S. with 30% of its liquid fuel! Some optimistic investigations of renewable energy have failed to recognize that only 0. 1% of the solar energy is captured annually in the U. S.

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.

Food versus Fuel presents a high-level introduction to the science and economics behind a well-worn debate, that will debunk myths and provide quality facts and figures for academics and practitioners in development studies, environment studies, and agricultural studies. Compiled by an internationally renowned scientist and authority, and to include perspectives from 'pro' and 'anti' biofuels experts and activists, from the North and South, the aim of this book is to bring a balanced approach to the current debate on the major issues affecting the development of biofuels in a concise and clear manner in order to provide an informed, nuanced but accessible introduction, grounded in science and economics rather than conjecture and controversy.

Energy and Society (Revised) When first published in 1955, this book was among the first interpretive treatments of the connection between a society's energy conditions and evolution of its culture. The book begins with a basic discussion of the earliest forms of energy uses and evolves through a discussion of how the evolution of alternative energy converters has impacted the growth of civilization. Dr.Cottrell takes us from food gathering societies up through the beginning of the industrial revolution into the age of nuclear power. With each step of change, he discusses how society has changed and the impact these changes have had on economic, moral and social issues. Today, more than any time in history, the questions of energy sources, energy conversion, energy uses and energy distribution are among the greatest challenges faced by civilization. In this book, Dr. Cottrell does not give you answers or predictions but takes you through the thought processes necessary to overcome the multible barriers we face in moving into the future.

Agroecology is a science, a productive practice, and part of a social movement that is at the forefront of transforming food systems to sustainability. Building upon the ecological foundation of the agroecosystem, Agroecology: The Ecology of Sustainable Food Systems, Third Edition provides the essential foundation for understanding sustainability in all of its components: agricultural, ecological, economic, social, cultural, and even political. It presents a case for food system change and why the current industrial model of food production and distribution is not sustainable. See What’s New in the Third Edition: Chapters on animal production and social change in food systems Updated case studies, references, websites, and new research Emphasis on how climate change impacts agriculture Greater focus on health issues related to food The book begins with a focus on the key ecological factors and resources that impact agricultural plants and animals as individual organisms. It then examines all of the components of agroecosystem complexity, from genetics to landscapes and explores the transition process for achieving sustainability and indicators of progress. The book then delves into power and control of food systems by agribusiness, and the need to develop a new paradigm that moves beyond production and explores issues of food justice, equity, food security and sovereignty. The book concludes with a call to action so that research and education can link together for transformative change in our food systems. Groundbreaking in its first edition, respected in its second edition, this third edition of this standard textbook has evolved along with the field. Written by an expert with more than 40 years of experience, the third edition begins with a strong ecological foundation for farming practices and ends with all of us thinking about the critical importance of transitioning to a new paradigm for food and agriculture, and what this means for our future.
