Biocapacity
The productive capacity of biologically productive land and water areas to provide resources and absorb wastes.
Formula
Biocapacity (gha) = Area × Yield Factor × Equivalence Factor
Real World
Brazil has one of the world's highest biocapacities due to the Amazon rainforest, giving it roughly 9.5 gha per person — far above the global average — making it a net ecological creditor nation.
Exam Focus
Use global hectares (gha) as your unit and distinguish biocapacity from biodiversity — examiners penalise conflation of the two terms.
