What is biologically productive land?
Table of Contents
biologically productive land and water. The land and water (both marine and inland waters) area that supports significant photosynthetic activity and the accumulation of biomass used by humans. Non-productive areas as well as marginal areas with patchy vegetation are not included.
How much of the earth is biologically productive for human use?
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 an example of an Ecological Footprint?
The Ecological Footprint tracks the use of productive surface areas. Typically these areas are: cropland, grazing land, fishing grounds, built-up land, forest area, and carbon demand on land.
What is ecological Reserve?
Ecological reserves are areas selected to preserve representative and special natural ecosystems, plant and animal species, features and phenomena. Scientific research and educational purposes are the principal uses of ecological reserves.
What is biocapacity person?
Biocapacity is expressed in terms of global hectares per person, thus is dependent on human population. A global hectare is an adjusted unit that represents the average biological productivity of all productive hectares on Earth in a given year (because not all hectares produce the same amount of ecosystem services).
What is an ecological reserve?
How much are overshooting our planet’s biocapacity?
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 the US biocapacity?
United States The U.S. has an ecological footprint of 8.04 gha per capita, one of the highest in the world, with a biocapacity per capita of only 3.45 hectares.
What is human ecological footprint?
The simplest way to define ecological footprint would be to call it the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.
Why are ecological reserves important?
Ecological reserves provide important wildlife habitat in many landscapes, and the functional connectivity of reserves and other suitable habitat patches is crucial for the persistence and resilience of spatially structured populations.

What is protected land in the United States?
Protected areas in the US conserve the wild flora and fauna of the country. The national parks are an important part of protected land in the United States. As of 2015, protected areas of the United States constituted 499,800 square miles. This area is 14% of the total land area of the US and a tenth of the world’s protected land area.
How are protected areas managed in the US?
Protected areas of the US are operated by various authorities. The authorities could be local, tribal, state or federal. Other areas are managed between levels of government. The level of protection of these areas is unique to each area. Some areas are managed as wildernesses.
How much land do Americans live in urban areas?
Small But Mighty: U.S. Urban Areas It’s clear that even a little space goes a long way. Although urban areas take up only 2% of land, an overwhelming majority of Americans call cities their home. As of 2018, urbanites made up over 82% of the U.S. population.
Who manages the national parks in the US?
The other areas are managed by the United States Fish and Wildlife Service, the Bureau of Land Management and the United States Forest Service. The International Union for Conservation of Nature (IUCN) describes the levels of protection.
