While many people around the world worry about deforestation in the Amazon rainforest, to most of us, it’s still remote. Most people have never visited the Amazon, and many have no idea what they can do about deforestation. But a new online tracking system relies on citizen scientists to help monitor the Amazon via satellite.
“You don’t have to be a climate scientist, you don’t have to be a data scientist, you just have to be a citizen that is concerned about the issue of deforestation,” said Elliot Inman, a researcher at systems analysis company SAS, as reported in Huffington Post. SAS worked with Austria-based International Institute for Applied Systems Analysis to create an app that depends on humans to look at images and help train artificial intelligence to spot deforestation.

World Resources Institute oversees the resulting Global Forest Watch tracking system. First, a computer algorithm scans incoming images. When it identifies a place where trees have recently disappeared, it flags that image. Human eyes are needed to help discern what might have caused those missing trees. Volunteers scan the images for signs of human impact, such as roads, farm plots or tree lines that are suspiciously straight. This human input helps train the artificial intelligence, so that eventually the system will be able to digest images more quickly on its own.
The system relies on consensus from multiple users. Sometimes it’s tricky to determine whether a brown patch on an image is due to humans burning trees to clear land for agriculture versus a natural forest fire. With a bit of training, citizen scientists are better able to notice small things that the computer might miss, such as a thin line that indicates a primitive road leading to the burned clearing.
Data gathered by the system will help conservation organizations and governments identify when they should intervene to protect ecosystems. In the future, Global Forest Watch may even help predict where deforestation will happen next. All you need to help is an internet connection and a little bit of free time.
