The earth has approximately 148,847,000 km2 and a population of 6,596,991,167 people. So the equation 148,847,000 km2 / 6,596,991,167= 0.2256km2/person
So thats about 2,428,338.19 square feet per person. Now keep in mind that counts many of the deserts and the mountain ranges that are inhospitable.
Enter the term "biocapacity." Biocapacity is a measure of the biological productivity in an area. It is a measure of the productivity of various ecosystems within the area, for example, arable or crop land, pasture, forest and bioproductive sea, built or degraded land.
The worldwide biocapacity is approximately 4 to 5 global acres per person.
The Ecological Footprint is expressed in "global acres." Each unit corresponds to one acre of biologically productive space with "world average productivity."
So there you have it. I hope one of those two measurements meets with your needs.

I am confused by your question.
Greenspace or Green Space (other countries refer to it as green belts or greenbelt) may refer to:
* Greenspace, an open urban space with plant life.
* Greenbelt, a policy or land use designation used in land use planning.
* Greenspace, an open source software for repositories.
* Greenway, a linear greenspace running through an urban area.
What information are you actually seeking?
