Uncovering the Impact of 'Ghost Roads' on Tropical Deforestation

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.
