The ecological footprint: a non-monetary metric of human consumption applied to North America
Abstract
This paper employs ecological footprint analysis as a potential non-monetary metric of human consumption and ecological productivity in a simulation-modeling framework, applied to North America. The ecological footprint provides an indirect basis for considering the long-term ecological risk and sustainability of human settlements, regions or, in this case, a continent. We examine several scenarios for human consumption, ecological productivity and material efficiency, to explore which variables have influence on the ecological budget of North America over the coming century. Only one scenario, which assumes considerable reductions in human consumption, is likely to yield an ecological surplus. Unlike monetary measures of societal well-being, ecological footprint analysis shows that increased economic activity and consumption creates deficits in terms of the balance of ecological productivity and consumption in a region, and may reduce long-term ecological sustainability. Several advantages and disadvantages of this metric are discussed.
