Spatial modeling analysis reveals that commodity production drives 27% of global forest loss, highlighting unfulfilled corporate commitments to halt permanent land conversion.

Key Points

To distinguish permanent deforestation from temporary canopy disturbance and classify the primary drivers of global forest loss between 2001 and 2015.
Developed a spatial classification model using satellite imagery to evaluate global forest disturbance from 2001 to 2015.
Attributed forest loss to dominant land cover and land use drivers, separating permanent conversion from temporary disturbances.
Permanent deforestation for commodity production drove 27% of global forest loss.
Temporary disturbances accounted for the remaining 73% of loss, divided among forestry operations (26%), shifting agriculture (24%), and wildfires (23%).
Commodity-driven deforestation rates failed to decline over the 15-year period, indicating supply chains must eliminate 5 million hectares of conversion annually to achieve zero deforestation.
