What we count
The annual net reduction in global forest area: deforestation losses after subtracting gains from natural expansion and planting.
Net forest area loss this year
Net forest area loss worldwide so far this year, based on FAO's latest assessment, and how net loss differs from deforestation.

What lies behind this number
The annual net reduction in global forest area: deforestation losses after subtracting gains from natural expansion and planting.
How the source derives it
FAO's Global Forest Resources Assessment harmonises national forest inventories, mapping and official country reports.
What one number cannot show
Net loss is smaller than gross deforestation and says nothing about the quality of new forests. Natural forest loss is not always offset by planting elsewhere.
Source value
The calculation uses the latest published annual value reported by FAO Global Forest Resources Assessment 2025 for 2015–2025 (average annual net change).
How the value is used: The running number shows the share corresponding to time elapsed since the start of the calendar year.
