Deforestation in Papua New Guinea
Since 2001, Papua New Guinea has lost about 1.99 million hectares of forest (about 20,000 km²): 4.6% of the forest it had in 2000. The biggest cause was shifting farming (43%), after which forest can grow back. About 264,000 hectares (13%) was deforestation: forest cleared for good for farms, mines or towns.

Causes
What is causing deforestation in Papua New Guinea?
- 13%cleared for good (deforestation)
- 85%can grow back (fire, logging, storms)
- 1.5%cause unknown
- Shifting farming43% · 858,000 ha
Can grow back. Small patches cleared to grow crops for a few seasons, then left to grow back.
- Logging27% · 540,000 ha
Can grow back. Trees cut for timber or paper. The land usually stays forest and grows back.
- Farms, pasture and plantations13% · 253,000 ha
Cleared for good. Forest cleared for crops, cattle pasture or tree plantations: the biggest cause of deforestation in the world.
- Storms, floods and other natural causes8.6% · 171,000 ha
Can grow back. Trees killed by storms, floods, landslides, pests or disease.
- Wildfires6.2% · 122,000 ha
Can grow back. Forest burned. It often grows back, though fire is sometimes used to clear land for good.
- Unknown causes1.5% · 30,500 ha
Cause unknown. The satellites saw the trees go, but not why.
Also, each under 1%: towns and roads, mining and energy.
Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.
Is all forest loss deforestation?
No. When forest is cleared for farms, mines or towns, it is gone for good: that is deforestation. When it is logged or burned, it usually grows back. We count both as forest lost, but only the first as deforestation, so a country with a bad fire year isn't shown as clearing its forest for good.

Frequently asked
Questions about deforestation in Papua New Guinea
How much forest has Papua New Guinea lost since 2001?
Since 2001, Papua New Guinea has lost about 1.99 million hectares of forest (about 20,000 km²): 4.6% of the forest it had in 2000. The biggest cause was shifting farming (43%), after which forest can grow back. About 264,000 hectares (13%) was deforestation: forest cleared for good for farms, mines or towns.
Is deforestation in Papua New Guinea getting worse?
Forest loss has stayed about the same: about 89,000 hectares a year in 2021–2025, against 116,000 hectares a year in 2016–2020. These are five-year averages from 2011 on, the years the satellite maps were all made the same way.
What is causing deforestation in Papua New Guinea?
The main causes of forest loss since 2001 are shifting farming (43%), logging (27%), farms, pasture and plantations (13%). About 264,000 hectares was deforestation, meaning forest cleared for good for farms, mines or towns. Causes for 2025 are estimates, based on what caused forest loss in the same places up to 2024.
What was the worst year for forest loss in Papua New Guinea?
The worst year was 2016, when about 176,000 hectares of forest were lost.
How is forest loss measured?
We use satellite maps from the University of Maryland (Hansen and colleagues) that show, for every 30 × 30 m patch of land on Earth, the year its trees were cut down, burned or died, from 2001 to 2025. We add up those patches in Papua New Guinea, counting only places that were at least 30% covered by trees in 2000. The cause of each loss comes from a map made by the World Resources Institute and Google DeepMind. All figures are estimates.
