Last year saw an uptick in fire activity in the Amazon basin. This year a new tool has been released that aims to help classify the fires being observed. The Amazon Dashboard classifies each fire as a deforestation fire, a savanna fire, a small clearing and agricultural fire, or an understory forest fire, and tracks whether the fire is in a protected or indigenous territory. NASA Earth Observatory:
The fire analysis tool is already bringing new clarity and insight to the 2020 fire season. In July, Brazil announced a 120-day ban on fires in the Amazon rainforest; it was presented as an effort to limit ecological damage from fires this year. However, the NASA-led fire analysis indicates that there has been a proliferation of fires in key deforestation hotspots in the southern Amazon states of Pará, Mato Grosso, and Amazonas.
Other raw data sources include the Copernicus Atmosphere Monitoring Service (CAMS), fire activity data from which can be viewed here; and MODIS data from NASA’s Terra and Aqua satellites. For a live feed of MODIS data on the Amazon fires, see the MODIS Wildfire Dashboard.
Meanwhile, NASA’s Earth Observatory posted MODIS imagery of several Amazon fires, and had this curious statement that seemed to minimize the scale of the problem: “As of August 16, 2019, an analysis of NASA satellite data indicated that total fire activity across the Amazon basin this year has been close to the average in comparison to the past 15 years. […] Though activity appears to be above average in the states of Amazonas and Rondônia, it has so far appeared below average in Mato Grosso and Pará, according to estimates from the Global Fire Emissions Database, a research project that compiles and analyzes NASA data.”
A subsequent NASA Earth Observatory post seems to contradict the one I mentioned earlier, pointing to “a noticeable increase in large, intense, and persistent fires burning along major roads in the central Brazilian Amazon” which “are more consistent with land clearing than with regional drought” and noted fire detections “higher across the Brazilian Amazon” since 2010.
Contextualizing the amount of fires seems to be a recurring theme in the reporting: the number of fires are up sharply over last year, but close to the average when taking a longer view. It’s helped a lot of bad and insincere actors make it harder to get to the heart of what’s going on over there. They can’t, after all, deny the satellite imagery or the remote sensing: we can see the fires. We can detect the emissions of smoke, carbon dioxide and carbon monoxide (1, 2, 3). We can map them. And those maps can help us understand what’s going on.
On the NGO front, InfoAmazonia has produced the above map comparing fires over the last 24 hours with historical fire data. (They have other maps on this subject as well.)
