An introduction to the use of expert systems in environmental planning, which describes the manner in which heuristic and practical knowledge can be represented through computer programs. The text presents ways of solving such problems as noise control and environmental impact assessment.
The connections between economics, planning, and the environment are receiv ing increased attention among scholars and policy makers in many countries. The common denominator among these three variables is the earth's life support sys tems, the ecosystems on which the world depends. When we describe our physi cal surroundings as a collection of possible uses, we are establishing linkages between economics, planning, and the environment. Because possible alternative uses compete with each other, and conflicts arise over scarce land resources, the varying environmental impacts of alternative uses are major concerns for the cur rent as well as the next generation. How to achieve sustainable development is the pressing question for today's environmental professionals. Environmental planners and engineers help us study the implications of our choices, and new technologies and techniques that improve the practice of environmental planning should enhance our ability to protect our future. The depletion of the earth's natural resources and loss of biodiversity, the deg radation of air, land, and water quality, the accumulation of greenhouse gases leading to changes in our climate, and the depletion of the ozone layer comprise only a partial list of environmental issues that concern our policy makers. To sup port their decisions, environmental planning must be a multidimensional and multidisciplinary activity that incorporates social, economic, political, geograph ical, and technical factors. Solutions for problems in these areas frequently re quire not only numerical analyses but also heuristic analyses, which in turn depend on the intuitive judgements of planners and engineers.
