Using an energy systems language that combines energetics, kinetics, information, cybernetics, and simulation, Ecological and General Systems compares models of many fields of science, helping to derive general systems principles.

First published as Systems Ecology in 1983, Ecological and General Systems proposes principles of self-organization and the designs that prevail by maximizing power and efficiency. Comparisons to fifty other systems languages are provided. Innovative presentations are given on earth homeostasis (Gaia); the inadequacy of presenting equations without network relationships and energy constraints; the alternative interpretation of high entropy complexity as adaptive structure; basic equations of ecological economics; and the energy basis of scientific hierarchy.

Part I introduces energetics, hierarchy, and systems modeling. Part II features design elements: intersections, autocatalytic modules, loops, series, parallel elements, and webs. Part III includes embodied energy, spectra of energy quality, temperature, complexity, spatial distribution, and diversity. Part IV discusses production, consumption, ecosystems, succession, economic systems, anthropological models, urban and regional models, global biogeochemistry, and the universe.

A Prosperous Way Down (2001), the last book by Howard T. and Elisabeth C. Odum, has shaped politics and planning as nations, states, and localities begin the search for ways to adapt to a future with vastly increased competition for energy.

A Prosperous Way Down considers ways in which a future with less fossil fuel could be peaceful and prosperous. Although history records the collapse of countless civilizations, some societies and ecosystems have managed to descend in orderly stages, reducing demands and selecting and saving what is most important.

The authors make recommendations for a more equitable and cooperative world society, with specific suggestions based on their evaluations of trends in global population, wealth distribution, energy sources, conservation, urban development, capitalism and international trade, information technology, and education.

Available for the first time in paperback, this thoughtful, provocative book forces us to confront assumptions about our world 's future and provides both a steadying hand and a call to action with its pragmatic analysis of a global transition.
