Biocapacity And Ecological Footprints Flashcards
How many organisations make up the global footprint network?
70 organisations
What sort of organisations are part of the global footprint network?
National governments
Research organisations
Social benefit organisations
What does the global footprint network produce information on?
Ecological footprints
Bio capacity
What is bio-capacity?
A measure of the biological productivity of an area (the whole planet or a selected smaller area)
What 5 areas is bio capacity calculated for?
Forests
Marine and inland waters
Cropland
Grazing land
Built-up areas
What can bio-capacity be affected by?
Human management methods such as farming methods as well as natural productivity
How can bio-capacity be increased?
Good management by humans
What can reduce bio-capacity of an area?
Habitat destruction or degradation
What does bio-capacity not assume?
That any land is reserved for the other species that could use the same area
What is land that is set aside for other species and wildlife communities called?
Biodiversity buffer
What is an ecological footprint?
The area of the earths surface that is needed to provide the resources that are used by the human population and to deal with the wastes produced
What will the total footprint need to be to support the human population sustainably?
The total footprint of the entire human population would need to be lower than the area of earths surface
What is a global hectare?
Refers to a hectare of land with a bio capacity that is the average of the whole planet
What is the concept of earth overshoot days?
Used to describe exploitation of the planets resources that occurs at a faster rate then the replacement rate so it will take more than a year for the earth to recover from a year of human exploitation
What is a carbon footprint?
This is the part of an ecological cycle that relates to the emission of carbon dioxide and other greenhouse gases
