What percent of land is biologically productive?

Wrap-up: Remind students that only the green and blue sections — about 23 percent of the Earth's surface — are biologically productive. This small percentage of land and water is all we have to produce all of our food, materials, and energy, and to absorb our waste.

What is the most biologically productive area?

The five area types for biocapacity that support the 6 Footprint demand types are: Cropland: Cropland is the most bioproductive of all the land-use types and consists of areas used to produce food and fiber for human consumption, feed for livestock, oil crops, and rubber.

What are examples of biologically productive land?

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.

What is the average ecological footprint?

The world-average ecological footprint was 2.75 global hectares per person (22.6 billion total) and the average biocapacity was 1.63 global hectares.

What country has the smallest Ecological Footprint 2020?

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 much land would every person have?

Subtracting this uninhabitable 57% (32,665,981 mi²) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land. Divide this figure by the current human population of 7 billion (that's 7,000 million people) and you get 2.3 acres (about one hectare) per person.

What's productivity in biology?

Definition of Biological productivity:

The quantity of organic matter or its equivalent in dry matter, carbon, or energy content which is accumulated during a given period of time.

What are the two most biologically productive habitats on Earth?

Two of the Most Diverse Ecosystems on Earth

Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

What is primary productivity in biology?

primary productivity, in ecology, the rate at which energy is converted to organic substances by photosynthetic producers (photoautotrophs), which obtain energy and nutrients by harnessing sunlight, and chemosynthetic producers (chemoautotrophs), which obtain chemical energy through oxidation.

What is gha per capita?

The global hectare (gha) is a measurement unit for the ecological footprint of people or activities and the biocapacity of the earth or its regions. ... "Global hectares per person" refers to the amount of production and waste assimilation per person on the planet.

Why is America's Ecological Footprint so high?

countries often listed as offering a higher or comparable quality of life than the U.S. Page 23 The primary explanation for the very large Ecological Footprint of the United States relative to Europe is higher energy and fossil fuel consumption, and the related function of biological resources in carbon cycling.

How much larger is our United States Ecological Footprint than the rate the planet can regenerate?

The U.S. footprint per capita was 9.0 gha, and that of Switzerland was 5.6 gha, while China's was 1.8 gha. The WWF claims that the human footprint has exceeded the biocapacity (the available supply of natural resources) of the planet by 20%.

How many Earths does the average American use?

Today humanity uses the equivalent of 1.75 Earths to provide the resources we use and absorb our waste, based on the 2022 edition of the National Footprint and Biocapacity Accounts. This means it now takes the Earth one year and eight months to regenerate what we use in a year.
