What is your ecological footprint in hectares?


Sharing is Caring


Your ecological footprint value is measured in global hectares (gha). A global hectare equates to 10,000 square meters (or 2.471 acres) and is approximately the size of a soccer field. Global hectares (gha) are used as a measurement unit to look at the physical area across various land-use types.

How many acres of land are biologically productive?

In contrast, globally there are currently 1.8 hectares (4.5 acres) of biologically productive land and sea area available per person. Maintenance of biodiversity also depends on this area.

What are biologically productive areas?

Biologically productive areas include cropland, forest and fishing grounds, and do not include deserts, glaciers and the open ocean. Using a common unit, i.e., global hectares, allows for different types of land to be compared using a common denominator.

How much productive land area is there on Earth?

There were ~ 12.2 billion hectares of biologically productive land and water on Earth in 2019.

How big is your ecological footprint?

The average human uses 2.6 global hectares yearly, which is more than the 1.7 gha per person available in the world. Our average footprint is so huge that we’re on track to exhaust the earth’s resources if we don’t make big changes soon.

What environment has the highest biological productivity?

An important measure of natural ecosystems is the biological production of its plants and animalsโ€”that is, the total amount of biomass produced by living organisms within a given area in a specific period of time. In polar regions the greatest biological production occursโ€ฆ

How many hectares are there in the world?

The Land Area of the World is 13,003 million ha.

Which ecosystem has greatest biological productivity?

The highest net primary productivity in terrestrial environments occurs in swamps and marshes and tropical rainforests; the lowest occurs in deserts.

How much larger is our ecological footprint than the rate the planet can regenerate?

For 2017 Global Footprint Network estimated humanity’s ecological footprint as 1.73 planet Earths. According to their calculations this means that humanity’s demands were 1.73 times more than what the planet’s ecosystems renewed.

Which country has the largest ecological footprint per person?

1. China. China had an ecological footprint of 3.71 hectares per capita and a biocapacity of 0.92 per capita in 2017. China’s total ecological footprint is 5.3 billion gha, the highest of any country in the world.

How much land is taken up by agriculture?

Agricultural land use and ownership remained virtually unchanged at 3.7 million hectares in 2020. 6.2 million hectares in 2020.

How much of the world’s land is arable?

The world has 15.749 million km(2) of arable land. Arable land is land ploughed or tilled regularly, generally under a system of crop rotation.

What is the average ecological footprint for a person living in the United States?

Ecological Footprint of average U.S. citizen is 7.0 gha (global hectares).

How many earth would we need if everyone lived like you?

Here’s how we calculate that, using the United States as an example: The Ecological Footprint for the United States is 8.1 gha per person (in 2018) and global biocapacity is 1.6 gha per person (in 2018). Therefore, we would need (8.1/ 1.6) = 5.1 Earths if everyone lived like Americans.

What country has the smallest ecological footprint and why?

While the smallest ecological footprint for a sovereign country is that of China’s neighbour North Korea, with 62,644.7 global hectares in total. North Korea is only surpassed by the British Overseas Territory of Montserrat in the Caribbean, with its footprint of 23,148.9 global hectares.

How many planets does it take to support your lifestyle?

It has been suggested that if everyone on the planet consumed as much as the average US citizen, four Earths would be needed to sustain them.

Which has highest productivity?

Solution : Coral reefs ecosystem has the highest gross primary productivity.

Which is highest productivity?

  1. Ireland. Ireland’s productivity per hour is the highest of any country at $99.13.
  2. Norway. Norway’s productivity per hour is $80.83.
  3. Switzerland. Switzerland is the third-most productive country.
  4. Luxembourg.
  5. Germany.
  6. United States.
  7. Denmark.
  8. France.

What is primary productivity in biology?

Primary productivity is the process by which organisms make their own food from inorganic sources. The majority of primary producers are terrestrial plants and microbial life, such as algae.

How many hectares does it take to feed a person?

The baseline diet โ€” what Americans are eating today โ€” required the most land at 1.08 hectares (2.67 acres, or more than two football fields) per person per year, followed by the reduced-fats-and-sweeteners diet at 1.03 hectares (2.55 acres) per person per year.

Which country has the best soil in the world?

Found in Ukraine, parts of Russia and the USA, mollisols are some of the world’s most fertile soil. This type of soil includes black soils with high organic content. Vertisols โ€“ 2.5% of the world’s ice-free land.

Which ecosystem makes up approximately 70% of the earth’s surface?

2 The marine biome is primarily made up of the saltwater oceans. It is the largest biome on planet Earth and covers around 70% of the Earth’s surface and over 90% of life on Earth lives in the ocean.

What are the top 3 most productive ecosystems?

In terrestrial ecosystems the order of productivity in decreasing order is 1. Swamps, marshes, tropical rain forests (most productive), 2. Temperate forest, 3. Northern coniferous forest (taiga), 4.

What is net productivity in biology?

Net primary productivity, or NPP, is gross primary productivity minus the rate of energy loss to metabolism and maintenance. In other words, it’s the rate at which energy is stored as biomass by plants or other primary producers and made available to the consumers in the ecosystem.

Why is China’s ecological footprint so small?

China is so densely populated that the per capita footprint is relatively small to the total ecological footprint.
