By the time you read the title, another tree had been cut down. Interpol revealed in a report that 90% logging is illegal. Illegal logging has been the second most reason for the climatic change and massive global extinctions.
THE SOLUTION HAS BEEN IN YOUR POCKET THE WHOLE TIME..
Rainforest Connection is a project started back in 2014 that uses old mobile phones as sound detectors and send alerts to local authorities present on the ground and get a real-time action on the loggers.
Topher White-CEO, Founder of Rainforest Connections in his TED Talks about the time when he visited the rainforest of Borneo and observed a thing that despite the presence of full time dedicated guards whose job was, in fact, to guard against illegal logging but within the 5 mins walk they see a man sawing a tree down a few hundred meters from the ranger station and the guards hadn’t been able to listen to chainsaws, because the forest is very very loud.
At that moment as an engineer Topher White come up with a very innovative solution to the problem is to use what is already present there. He observed there was full time dedicated guards that were dedicated to go and stop it but they needed to know what was happening out in the forest so there comes a role of the model that picks up programmatically the sound chainsaws and send an alert.
HOW DOES IT WORK?
The current status for detection of destruction relies on satellites which show rainforest destruction after days or weeks which is too late. Modern smartphones are powerful and versatile tools which have all the required sensors and work really well as wireless sound detectors. Rainforest connection converts recycled smartphones into an autonomous listening device that can detect signs of destructive activities from a great distance.
The moment a sound of the chainsaw is heard in the forest, the device catches the sound of a chainsaw and then it sends an alert through the standard GSM network availabe there to a ranger in the field who can, in fact, show up in real time and stop logging.
HOW DO SMARTPHONES GETS POWER?
Power a cell phone under a tree was still an unsolved engineering challenge. To deal with the problem they built a unique solar power design which was built from recycled byproducts of an industrial process.
