Research on Ghost Roads in Tropical Forests

Ghost roads, often illegal or informal, are roads created for exploiting natural resources. Researchers found that there are significantly more ghost roads in the Asia Pacific region than previously documented. The study utilized volunteers and AI technology to map these hidden highways, revealing up to 6.6 times more roads than existing maps showed. The impact of these ghost roads on deforestation was substantial, contributing significantly to habitat loss and biodiversity decline.

00:46 Mapping ‘ghost roads’ in tropical forests

Across the world, huge numbers of illegal roads have been cut into forests. However, due to their illicit nature, the exact numbers of these roads and their impacts on ecosystems is poorly understood. To address this, researchers have undertaken a huge mapping exercise across the tropical Asia-Pacific region. Their findings reveal over a million kilometers of roads that don’t appear on official maps, and that their construction is a key driver for deforestation.
