Concept of ecological footprint

Footprint measurements and methodology[ edit ] The natural resources of Earth are finiteand unsustainably strained by current levels of human activity. ForGlobal Footprint Network estimated humanity's ecological footprint as 1. This means that, according to their calculations, humanity's demands were 1.

Cities, due to their population concentrationhave large ecological footprints and have become ground zero for footprint reduction. This approach can also be applied to an activity such as the manufacturing of a product or driving of a car.

This resource accounting is similar to life-cycle analysis wherein the consumption of energybiomass foodfiberbuilding materialwater and other resources are converted into a normalized measure of land area called global hectares gha.

Per capita ecological footprint EFor ecological footprint analysis EFAis a means of comparing consumption and lifestyles, and checking this against nature's ability to provide for this consumption.

The tool can inform policy by examining to what extent a nation uses more or less than is available within its territory, or to what extent the nation's lifestyle would be replicable worldwide. The footprint can also be a useful tool to educate people about carrying capacity and overconsumptionwith the aim of altering personal behavior.

Ecological footprints may be used to argue that many current lifestyles are not sustainable. Such a global comparison also clearly shows the inequalities of resource use on this planet at the beginning of the twenty-first century.

Inthe average biologically productive area per person worldwide was approximately 1. The world-average ecological footprint in was 2. The increase of biocapacity averaged at only 0.

Because of agricultural intensification, biocapacity was at 9. InEarth Overshoot Daythe date where humanity has used more from nature then the planet can renew in the entire year, was estimated to be August 1 [22].

This means their ecological footprint for consumption exceeds the biocapacity of that country.

Despite being populated by relatively "mainstream" home-buyers, BedZED was found to have a footprint of 3. The report did not measure the added footprint of the 15, visitors who have toured BedZED since its completion in Findhorn Ecovillagea rural intentional community in MorayScotlandhad a total footprint of 2.

However, the residents alone have a footprint of 2. However this should not be surprising, since the two methods address different research questions.

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.of the older idea of ecological footprint, a concept invented in the early s by Canadian ecologist William Rees and Swiss-born regional planner Mathis Wackernagel at the University of British Columbia.

On the demand side, the Ecological Footprint measures the ecological assets that a given population requires to produce the natural resources it consumes (including plant-based food and fiber products, livestock and fish products, timber and other forest products, space for urban infrastructure) and to absorb its waste, especially carbon emissions.

Ecological Footprints (EFs) are an assessment of humanities dependence on natural resources. Mathis Wackernagel and William Rees defined the concept of EF.

The Theory [excerpt from srmvision.com] Virtual water content: The virtual-water content of a product (a commodity, good or service) is the volume of freshwater used to produce the product, measured at the place where the product was actually produced (production-site definition).
