The amount of biocapacity available per person globally is calculated by dividing the 11.2 billion global hectares of biologically productive area by the number of people on Earth (6.3 billion in 2003). This ratio gives the average amount of biocapacity available on the planet per person - 1.8 global hectares.
How is biocapacity deficit calculated?
The biocapacity of an area is calculated by multiplying the actual physical area by the yield factor with the appropriate equivalence factor. Biocapacity is usually expressed in global hectares (gha).
What is biocapacity measured in?
global hectares
How do you quantify the Ecological Footprint and biocapacity?
The Ecological Footprint of a person is calculated by adding up all of people's demands that compete for biologically productive space, such as cropland to grow potatoes or cotton, or forest to produce timber or to sequester carbon dioxide emissions.
How do you calculate the area of a footprint?
Conventionally in construction the building footprint is the area of a building measured from the outer surface of the exterior of the building multiplied by the depth measured in the same manner to give a square area.
How do you calculate your carbon footprint manually?
- Multiply your monthly electric bill by 105.
- Multiply your monthly gas bill by 105.
- Multiply your monthly oil bill by 113.
- Multiply your total yearly mileage on your car by .79.
- Multiply the number of flights you've taken in the past year (4 hours or less) by 1,100.
