Biocapacity is nature's supply, and sustainability depends on whether it can keep up with demand

Definition

Biocapacity

Biocapacity is the capacity of a biologically productive area to continuously provide renewable resources and assimilate the waste generated by human activities.

Biocapacity is the capacity of a given area of biologically productive land and water to regenerate resources and absorb waste.
It is measured in global hectares (gha), the same unit as the ecological footprint, so the two can be compared directly.
A global hectare standardises land and water by average global productivity, so one gha represents the same regenerative capacity anywhere.

Example

A hectare of fertile farmland has a higher biocapacity than a hectare of desert.

Biocapacity is the supply side of the sustainability balance

The ecological footprint is the demand a population places on land and water, and it is defined in article 1.3F.
Biocapacity is the supply, meaning how much productive land and water is available to meet that demand.
