The National Institute for Space Research ('INPE - Instituto Nacional de Pesquisas Espaciais') reported on Thursday (28th) that, during the quarter of February, March and April this year, the forest cover change alerts from Amazon, including clear-cutting (total destruction) and degradation (partial destruction) totaled 550 km2. This number is 62.7 larger than the 338 km2 recorded in the same period last year.

The INPE reported on Thursday (28th) that, during the quarter of February, March and April this year, the forest cover change alerts from Amazon, including clear-cutting (total destruction) and degradation (partial destruction) totaled 550 km2. This number is 62.7 km2 larger than the 338 km2 recorded in the same period last year.
Of the total identified by INPE between February and April this year, an estimated 362 km² (65.8%) are areas of deforestation by clear-cutting and 180 km2 correspond to areas of forest degradation. Mato Grosso is the State that had the largest area of alerts – 264.4 of 550 km2.
The information is from 'Deter' - the real-time detection system.
According to the INPE, the 'Deter' serves to guide the supervision in the field and curb the illegal deforestation. The system is not used for the accurate measurement of area, as is done with moderate resolution satellite images and there's always a margin of false positives.
In addition, it takes into account the cloud cover, which can disrupt the satellite view of the territory.
