Satellite system prevents Africa's deforestation

A system that uses satellite data to send an alert alert when a tree is felled has contributed to a significant reduction in forest loss in Africa, the Thomson Reuters Foundation reported, citing researchers and educators.
Deforestation dropped by an average of 18 per cent in nine countries in central Africa after the whistleblowing system was triggered, a study published in the magazine found.Nature Clymouth Change”, quoted by BTA.

"It's a small revolution,” says study head Fanny Moffett, a postdoctoral fellow at the University of Wisconsin-Madison.

Trees absorb about a third of the world's greenhouse gas emissions, but rainforests in 2019 were disappearing at breakneck speed - every six seconds a forest array the size of a football field was disappearing, according to data from a forest surveillance project Global Forest Watch.

Scientists have examined whether the system triggered by Global Forest Watch in 2016 affects deforestation in 22 tropical countries in South America, Africa and Asia.

The system works by using artificial intelligence, viewing and comparing satellite images from a database updated every eight days. When the pictures show that trees have disappeared, the system signals the subscribers in the relevant area so they can examine what is happening on the ground and take action. Among the subscribers of the system are governments, parks management, NGOs.

They use the submitted data to deploy additional patrols to areas where tree felling has been recorded and to catch offenders on the ground, says Katherine Shea of Global Forest Watch.

The risk of deforestation fell by 18 per cent for the period 2016-2018 compared to previous years in Cameroon, the CAR, the Democratic Republic of the Congo and six other African countries.

However, the system has not affected similarly and has not reduced deforestation in South America and Asia.
