Environmental Accounting Emergy and Environmental Decision Making In this important new work, Howard T. Odum, widely acknowledged as the father of systems ecology, lucidly explains his concept of emergy, a measure of real wealth that provides a rational, science-based method of evaluating commodities, services, and environmental goods. Using specific real-world examples, Dr. Odum clearly demonstrates the revolutionary role of emergy in environmental management and policy making. Environmental Accounting: Emergy and Environmental Decision Making offers environmental professionals—policymakers, managers, ecologists, planners, developers, and activists—a systematic approach to environmental and economic valuation that will eliminate much of the rancor and adversarial decision making that often plagues environmental issues. Specifically, this book:
- Describes the theoretical basis, calculation procedures, and applications of emergy
- Introduces the concept of «transformity,» the ratio of emergy (work put into a product) and energy (value received from the product)
- Provides formulas for emergy calculations, procedures for making an emergy evaluation table, and parameters for updating evaluations
- Demonstrates the use of emergy to evaluate environments, minerals, waters, primary energy sources, economic developments, and international trade
- Compares the emergy approach to environmental evaluation with others
En 1996 ya había una edición revisada a cargo de University Press of Colorado. La de 2008 parece ser la 3ª edición.
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.
