Ecological footprint

These figures are the basis of claims such that if all of humanity consumed like the average American, five Earths would be needed. Furthermore, such moral conclusions seem to be an argument for autarky.

Ecological footprint

Both can be applied to products, people or whole societies. Meanwhile, social scientists have used the EF as a comprehensive indicator of the ecological impacts of humans on the planet in order to test empirically different social theories of the forces driving those impacts.

List of countries by ecological footprint

Newman has argued that the ecological footprint concept may have an anti-urban bias, as it does not consider the opportunities created by urban growth.

EFs also vary greatly within countries according to level of affluence. Critics also argue that the EF methodology rewards more-intensive production methods that increase yields per unit of land in the short term but might actually be less sustainable in the long run—for example, accelerating land degradation.

Those calculators allow people to calculate their personal EF and to make comparisons with estimates of available biocapacity or to average footprints of other people locally and globally. The first set of standards for proper calculation and communication of the EF was produced inand continual revisions are occurring.

Despite being populated by relatively "mainstream" home-buyers, BedZED was found to have a footprint of 3. This is because these communities have little intrinsic biocapacity, and instead must rely upon large hinterlands.

The World Nuclear Association provides a comparison of deaths due to accidents among different forms of energy production.

One hectare equals 2. Similarly, if organic farming yields were lower than those of conventional methods, this could result in the former being "penalized" with a larger ecological footprint. Cities, due to population concentrationhave large ecological footprints and have become ground zero for footprint reduction.

While improvements are still possible, there are already standards available sincewith updates in This compares to for natural gas and for coal according to this study. Footprint measurements and methodology[ edit ] The natural resources of Earth are finiteand unsustainably strained by current levels of human activity.

If the use of ecological footprints are complemented with other indicators, such as one for biodiversitythe problem might be solved. The resulting figures can also be compared with how much productive area—or biocapacity—is available.

Ecological footprint: Ecological footprint (EF), measure of the demands made by a person or group of people on global natural resources. It has become one of the most widely used measures of humanity’s effect upon the environment and has been used to highlight both the apparent unsustainability of current practices and.

First, we need a little information from you.

National ecological surplus or deficit, measured as a country's biocapacity per person (in global hectares) minus its ecological footprint per person (also in. First, we need a little information from you.: Ecological Footprint Quiz by Center for Sustainable Economy.

The Ecological Footprint tracks the use of six categories of productive surface areas: cropland, grazing land, fishing grounds, built-up land, forest area, and carbon demand .
