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 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 is your ecological footprint in hectares?
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.
What is biological capacity?
Similar term(s): biological capacity. Definition: Biocapacity refers to the capacity of a given biologically productive area to generate an on-going supply of renewable resources and to absorb its spillover wastes. Unsustainability occurs if the area’s ecological footprint exceeds its biocapacity.
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.
What country has the largest ecological footprint?
China Trends China continues to have the largest total Ecological Footprint of any country—no surprise given its huge population.
What environment has the highest biological productivity?
An important measure of natural ecosystems is the biological production of its plants and animals—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 occurs…
How big is a global hectare?
Hectare equivalents A hectare (/ˈhɛktɛər/; symbol ha) is a unit of area equal to 10,000 square metres (107,639 sq ft) (a square 100 metres on each side or 328 feet on each side), 2.471 acres, 0.01 square kilometers, 0.00386102 square miles, or one square hectometre (100 metres squared).
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.
How many Earths does it take to produce the resources humanity used in a year?
According to 2017 Global Footprint Network data reported by the World Wildlife Fund, the US is a close second to Australia in being a resource hog. The WWF report shows that it would take five planet earths to support humanity for a year if everyone lived the way Americans do.
What country has the smallest ecological footprint 2021?
According to the most recent data published by the GFN, the countries with the smallest ecological footprint per person are East Timor (aka Timor Leste) in south-east Asia and Eritrea in East Africa, each with 0.5 global hectares per citizen.
What is the maximum population the Earth can sustain?
Earth’s capacity Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people.
What is carrying capacity of Earth?
Depending on the metrics used, estimates of the earth’s carrying capacity can range from as small as a half a billion people to as large as 14 billion people.
What are the biological capacity for humans?
Scientists have determined that the carrying capacity of Earth for humans lies somewhere between four billion and 15 billion persons.
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.
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.
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.
Why is China’s ecological footprint so high?
China is now the nation with the world’s largest total Ecological Footprint. Two factors that drive increasing total Ecological Footprint are increasing per capita Ecological Footprint (a measure of increasing consumption) and population growth. It is widely known that China has the world’s largest population.

Which 3 ecosystems have the highest productivity and which 3 have the lowest productivity?
What types of ecosystems have the highest productivity per unit area? Estuaries, swamps and marshes, tropical rain forests, and temperate rain forests. What ecosystems have the least amount of productivity per unit area? Tundras, the open ocean, desert scrubs, and the extreme desert.
How much are overshooting our planet’s bio capacity?
Since global biocapacity that year was 1.7 gha per person, the EF of humanity overshot Earth’s biocapacity by 1.1 gha. In other words, 1.7 “Earths” would be needed to sustain current resource demands or, alternatively, it takes Earth more than one year and eight months to regenerate what is used in one year.
What is a high ecological footprint?
All the food we eat, the clothes we wear, the products we buy and the waste we generate – they all use up our natural resources and affect our environment. If you buy food mindlessly, waste half of it, do not recycle and use your vehicle to go a couple of blocks away, then you have a high Ecological Footprint.
