Abstract

The useful ‘ecological footprint’ approach is not new. In 1967, Bergstrom used the term ‘ghost acreage’ to reflect the area of agricultural land required for food consumption. Using the concept of energy density (the amount of energy consumed per unit of area per year), Odum in 1989 estimated that cities and industrial areas occupy 6 per cent of the continental US, but when their ecosystem shadow area is included, they appropriate about 35 per cent.
