“This year, 5,800 square kilometres (km2) were cleared, which was an 11% drop compared to last year. You can see this in the chart below, which shows deforestation rates since the late 1980s.
This data comes from PRODES (Program for the Calculation of Deforestation in the Legal Amazon), which carries out satellite monitoring of the region to detect deforestation. It also incorporates data from DETER, which is a rapid alert system that tries to detect changes in forests as they happen.”
