## How to Calculate Biocapacity
Biocapacity measures the capacity of ecosystems to produce useful biological materials and absorb waste.
### Formula
**Biocapacity (gha) = Area (ha) * Equivalence Factor * Yield Factor**
### Equivalence Factors
- Cropland: 2.51 gha/ha
- Forest: 1.26 gha/ha
- Grazing land: 0.46 gha/ha
- Fishing grounds: 0.37 gha/ha
Yield factor adjusts for local productivity relative to world average (e.g., 1.5 for fertile US farmland, 0.5 for arid regions).

Exemple Résolu
200 acres cropland, 500 acres forest, 300 acres grazing with yield factor 1.0.
- Cropland: 200 * 0.4047/10000 * 2.51 * 1.0 = 0.0203 gha
- Forest: 500 * 0.4047/10000 * 1.26 * 1.0 = 0.0255 gha
- Grazing: 300 * 0.4047/10000 * 0.46 * 1.0 = 0.0056 gha
- Total biocapacity: 0.0514 gha
