MEANINGS OF ENVIRONMENTAL TERMS

Certain terms and expressions that relate to the environment are probl ematic in that they vary widely in usage within and between discipline s, and several have been used as synonyms. In an attempt to correct th e problem and standardize usage, this paper defines or redefines 10 of the most common environmental terms. Two of these terms, natural envi ronment and environmental change, are defined on the basis of what is meant by natural as reflected by common usage and dictionary entries. The three degradation terms, environmental degradation, land degradati on, and soil degradation, are defined as any change or disturbance to the environment, land, or soil perceived to be deleterious or undesira ble. A sixth term, soil regeneration, is defined as the reformation of degraded soil through biological, chemical, and/or physical agencies. The remaining four terms, environmental quality, air quality, soil qu ality, and water quality, are defined as measures of the condition or state of each relative to the requirements of one or more biotic speci es and/or to any human need or purpose.
