Can ecological footprints be calculated for individual people or for populations?

Does ecological footprint depend on population?

Population density can affect the size of the average ecological footprint of a person. A low population density means that there is a lot of land area per person in that country. More land area and resources may be available for a person to use in his/her lifestyle.

Are ecological footprints the same for every person?

Every human produces an individual ecological footprint that is determined largely by the wealth and level of development in the country they live in—more developed countries have a larger footprint on average—but the choices we make in our daily lives also contribute.

What is ecological footprint per person?

It is the ratio of an individual’s (or country’s per capita) Footprint to the per capita biological capacity available on Earth (1.6 gha in 2019). In 2019, the world average Ecological Footprint of 2.7 gha equals 1.75 planet equivalents.

Why do ecological footprints vary between individuals?

Your ecological footprint is affected by how much land you live on, if you drive (how much do you drive, what is the gas mileage of your car, what are the emissions laws in your country for cars), what foods you eat and where they come from, where your electricity comes from, and so forth.

How ecological footprint is calculated?

The Ecological Footprint of a person is calculated by adding up all of people’s demands that compete for biologically productive space, such as cropland to grow potatoes or cotton, or forest to produce timber or to sequester carbon dioxide emissions.

What factors go into calculating an ecological footprint?

The calculation of the ecological footprint takes into account the following two factors:

  • The Earth’s biocapacity, i.e. the planet’s capacity to produce resources;
  • Human activity and its ecological impact, i.e. the resources consumed by humans and their waste.

What is human population size that the Earth can support if everyone has your ecological footprint?

The average American uses about 9.7 hectares. These data alone suggest the Earth can support at most one-fifth of the present population, 1.5 billion people, at an American standard of living.

Which country has the largest ecological footprint per person?

Countries and regions

Rank Country/region Ecological footprint
(gha/person)
World 2.75
1 Luxembourg 15.82
2 Aruba 11.88

How is per capita ecological footprint calculated?

The sum of the global hectares needed to support the biocapacity demand of the population gives that population’s total Ecological Footprint. The Ecological Footprint values (expressed in gha) can be divided by the size of the population to determine the Ecological Footprint per capita (expressed as per capita gha).

How do we use the ecological footprint to evaluate where the human population is relative to the our carrying capacity?

An ecological footprint is the area required to sustainably support a given population rather than the population that a given area can sustainably support. An ecological footprint is therefore the inverse of carrying capacity and provides a quantitative estimate of human carrying capacity.

How do you think average per capita income is related to ecological footprints?

The empirical results show that the effect of GDP per capita on the ecological footprint varies for different income levels. The effect of urbanization is significantly positive across income levels, which means that the higher the rate of urbanization in high or low income country, the higher the ecological footprint.
