New satellite programme aims to cut down illegal logging in real time
Taken from outer space, the satellite images show illegal loggers cutting a road into a protected area in Peru, part of a criminal enterprise attempting to steal millions of dollars worth of ecological resources.
With the launch of a new satellite mapping system on Wednesday, governments and environmentalists will have access to hard evidence of these types of crimes almost in real time as part of a push by scientists to improve monitoring of tropical deforestation.
Tropical forests nearly the size of India are set to be destroyed by 2050 if current trends continue, a study warned last year, causing species loss, displacement and a major increase in climate-changing greenhouse gas emissions.
Prior to the launch of the Global Land Analysis and Discovery (GLAD) alerts, researchers would have to manually track images of logging in specific areas.
The new process, developed by scientists at the University of Maryland and Google, uses an algorithm to analyze weekly updates of satellite images and sends automatic notifications about new logging activity.
"This is a game changer," said Matt Finer from the Amazon Conservation Association, an environmental group.
His organization tracks illegal logging in Peru, sending images of deforestation to policymakers, environmentalists and government officials to try and protect the Amazon rainforest.
In the past, he would rely on tips from local people about encroachment by loggers, then look at older satellite images to try and corroborate the claims.
"With this new data we can focus on getting actionable information to policy makers," Finer told the Thomson Reuters Foundation.
