We have documented 1,650 major fires in the Brazilian Amazon this year, and well over half (60%) have occurred in September.*

We have been detecting around 62 major fires a day during September, relative to 18 in August (and 2 in July).

Moreover, we flag the major spike in Amazon forest fires, defined here as human-caused fires in standing forest.

We found over 700 forest fires, which now account for 43% of all major fires, up from 13% in August (and just 1% in July).

We roughly estimate that 4.6 million acres (1.8 million hectares) have been impacted by these forest fires in the Brazilian Amazon.

The satellite image to the right is just one example of a recent major forest fire in the Brazilian Amazon. Below, for greater context, we show a before and after panel of that same fire.

Many of the major fires (49%) continue to burn recently deforested areas, defined here as areas where the forest was previously and recently cleared (between 2018 and 2020) prior to burning. This percentage, however, was much higher earlier in the fire season (For example, 84% in July).

Check out Mongabay’s real-time Brazilian Amazon fire tracker based on our analysis.

*The data, updated through September 20, is based on our novel real-time Amazon Fires Monitoring app, which is based on the detection of elevated aerosol emissions that indicate the burning of large amounts of biomass (defined here as a “major fire.”

Although August was severe, early September saw the Brazilian Amazon fires intensify even more.

September shot up to an average of 53 major fires per day across the Brazilian Amazon, up from 18 in August (and 2 in July).*

In addition, the surrounding Pantanal, the world’s largest tropical wetlands, is experiencing unprecedented fires.

The Base Map shows major fires scattered across the Brazilian Amazon in relation to the huge fire complex to the south in the Pantanal, as seen in our novel real-time fire monitoring app from early September.

Red indicates the most intense fires burning the highest levels of biomass.

Overall, we have now detected 963 major fires this year in the Brazilian Amazon with the app.

*Data updated through September 7, 2020.

Increase in Amazon Forest Fires

Also noteworthy is the major spike in Amazon forest fires, defined here as human-caused fires in standing forest. Forest fires now account for a striking 27% of all major fires, up from 13% in August (and 1% in July).

An estimated 896,000 acres (362,000 hectares) have been impacted  by these Amazon forest fires.

The majority of the major fires (66%) continue to burn recently deforested areas, defined here as areas where the forest was previously and recently cleared (between 2018-20) prior to burning.

In fact, over 1.3 million acres (540,000 hectares) of recently deforested areas has burned in 2020.

Thus, most of the fires are actually a smoking indicator of the current rampant deforestation in the Brazilian Amazon.

Protected Areas and Indigenous Territories

We also must highlight that we have detected 80 major fires in protected areas and indigenous territories of the Brazilian Amazon. The most impacted areas are the Xingu and Kayapó indigenous territories, and Jamanxim National Forest.

*Notes and Methodology

Our novel Real-time Amazon Fire Monitoring app

Data updated as of September 7, starting from the first major fire detected on May 28.

We detected 569 major fires during August in the Brazilian Amazon.

Prior to August, we detected only one forest fire, and that was on July 31.

The app specializes in filtering out thousands of the traditional heat-based fire alerts to prioritize only those burning large amounts of biomass (defined here as a major fire).

In a novel approach, the app combines data from the atmosphere (aerosol emissions in smoke) and the ground (heat anomaly alerts) to effectively detect and visualize major Amazon fires.

When fires burn, they emit gases and aerosols. A new satellite (Sentinel-5P from the European Space Agency) detects these aerosol emissions. Thus, the major feature of the app is detecting elevated aerosol emissions which in turn indicate the burning of large amounts of biomass. For example, the app distinguishes small fires clearing old fields (and burning little biomass) from larger fires burning recently deforested areas or standing forest (and burning lots of biomass).

We define “major fire” as one showing elevated aerosol emission levels on the app, thus indicating the burning of elevated levels of biomass. This typically translates to an aerosol index of >1 (or cyan-green to red on the app). To identify the exact source of the elevated emissions, we reduce the intensity of aerosol data in order to see the underlying terrestrial heat-based fire alerts. Typically for major fires, there is a large cluster of alerts. The major fires are then confirmed, and burn areas estimated, using high-resolution satellite imagery from Planet Explorer.

See MAAP #118 for additional details on how to use the app.

No fires permitted in the Brazilian state of Mato Grosso after July 1, 2020. No fires permitted in all of Brazilian Amazon after July 15, 2020. Thus, we defined “illegal” as any major fires detected after these respective dates.

A major fire may be classified as burning across multiple land categories (for example, both recently deforested area and surrounding forest fire) so those percentages do not total 100%.

There was no available Sentinel-5 aerosol data on July 4, 15, and 26.

The Brazilian Amazon just passed a grim milestone: Over 500 illegal major fires thus far in 2020.

The other major headline is that, although most fires continue to burn recently deforested areas, we are now seeing an increase in forest fires.

Our Real-time Amazon Fire Monitoring app has detected 504 major fires in the Brazilian Amazon as of August 24 (starting from the first major fire detected on May 28).

Finer M, Vale H, Villa L, Nicolau A (2020) Over 500 Illegal Major Fires in Brazilian Amazon. MAAP.

Our innovative new app for Real-time Amazon Fire Monitoring has now detected over 350 major fires in the Brazilian Amazon this season.*

Specifically, we have detected 365 major fires as of August 17, since the first major fire detected on May 28.

The fire season is accelerating, as 79% of the major fires have occured in August.

Below, we present a series of satellite images showing key examples from August 2020.

We highlight our key finding that the vast majority of major fires (88%) burned recently deforested areas covering 557,000 acres (226,000 hectares). Thus, the fires are actually a striking indicator of the rampant deforestation currently threatening the the Brazilian Amazon.

We have detected 4 Forest fires (1% of the major fires) covering 2,790 acres (1,130 hectares) and 3 savanna fires covering 38,000 acres (15,000 hectares). The rest of the major fires are burning older agricultural areas.

Other key findings include:

• The vast majority of the fires (96%) are illegal, occuring past the 120 day moratorium established in July.
• At least 18 of the major fires have been in protected areas or indigenous territories.
• Most of the fires (70%) have occurred in two departments: Amazonas and Para. Mato Grosso and Rondonia each account for 15%.

We have detected an additional 10 major fires in the Bolivian Amazon, and that will be the feature of a future report.

Our innovative new app for Real-time Amazon Fire Monitoring has detected over 200 major fires in 2020.

The app specializes in filtering out thousands of the traditional heat-based fire alerts to prioritize only those burning large amounts of biomass (defined here as a major fire).*

Our key findings include:

• We have detected 227 major Amazon fires (Brazil 220, Bolivia 6; Peru 1), as of August 10.
  ,
• The vast majority of major fires have been in the Brazilian Amazon, where a strikingly high number (85%) have burned recently deforested areas. Thus, the fires are actually a smoking indicator of the rampant deforestation now in Brazil.
  k
• In Brazil, we have detected two forest fires, but this risk increases as we get deeper into the dry season. The rest of the fires have been on older fields.
  l
• In Brazil, the vast majority (94%) of the major fires have been illegal, in violation of the state and national fire moratoriums established in July. In fact, despite the moratoriums, the number of major fires is accelerating: 143 so far in August following 77 in May through July.
  m
• In Brazil, 14 of the fires have been in Protected Areas.
  k
• In the Bolivian and Peruvian Amazon, we have recently started detecting fires in the drier ecosystems (savannahs and grasslands).

See below for a more detailed breakdown of the results.

Additional Results

The Base Map is a screen shot of the app’s “Major Amazon Fires 2020” layer.

The vast majority of the fires have been in the Brazilian Amazon: Pará (37%) and Amazonas (39%), followed by Mato Grosso (17%) and Rondônia (8%).

Importantly, the vast majority of the major fires in the Brazilian Amazon (85%) have burned recently deforested areas (cleared between 2018 and 2020) covering 280,000 acres (113,000 hectares). Thus, we argue that the central issue is actually deforestation and the fires are actually a smoking indicator of this forest loss.

We have detected the first two forest fires, burning 388 acres (1,447 hectares) in Mato Grosso and Para.

The rest of the major fires have been on older cattle or agricultural lands (deforested prior to 2018).

The most impacted protected areas are Jamanxim and Altamira National Forests in Pará. We emphasize, however, that these fires were burning recently deforested areas (not forest fires) and so, again, the primary issue is deforestation.

In Brazil, the vast majority of the major fires (94%) appear to be illegal as they violate the state and national government mandated fire moratoriums established in July. In fact, despite the moratoriums, the number of major fires is accelerating: 143 so far in August, following 64 in July, 12 in June, and the first one in May.

In the Bolivian Amazon, we have recently started detecting fires in the savannahs in the department of Beni. We also detected one fire in a recently deforested area in the Santa Cruz department.

In the Peruvian Amazon, we have recently started detecting fires in the upper elevation grasslands. The biggest one was actually within a protected area (Otishi National Park). There have also been smaller grassland fires near the buffer zone of upper Manu National Park.

Key Examples of 2020 Fires

Overall our key finding is that most major Brazilian Amazon fires are burning recently deforested areas, and not raging forest fires. Below is a series of satellite image time-lapse videos showing examples of recent deforestation followed by a major 2020 fire.

As of the end of July, we have detected 77 major Amazon fires thus far in 2020, all in Brazil.

In summary, 84% of the major fires are burned recently deforested areas and 83% were illegal (in violation of fire moratoriums). We detected the first forest fire on the last day of the month.

We have started detecting large and uncontrolled fires in the drier ecosystems of Bolivia, but outside the Amazon watershed.

Base Map. Screen shot of the app’s “Major Amazon Fires 2020” layer.

As noted above, we have detected 77 major Amazon fires thus far in 2020, all in Brazil.

The first major fire was detected on May 28 in the state of Mato Grosso in southeastern Brazilian Amazon (see MAAP #118). This event was followed by 12 major fires in June, all in Mato Grosso (see Fire Tracker #12).

The number of major fires in Mato Grosso decreased in July, suggesting the state’s new fire moratorium (starting July 1) may be working.

Starting in mid-July, the major fire activity shifted to the surrounding Brazilian states of Amazonas, Rondônia and Pará. This shift coincided with national fire moratorium (starting July 15), indicating it has not been as effective.

Overall, most of the major fires (83%) appear to be illegal as they violate the state and national government mandated fire moratoriums established in July.

Importantly, most of the major fires (84%) have burned recently deforested areas (deforested 2018-20) covering 108,000 acres (44,000 hectares). See MAAP #113 for more on this important point in regards to the 2019 fires.

We detected the first forest fire on the last day of the month. It burned 388 acres (157 hectares).

The other major fires have been in older cattle or agricultural areas (deforested pre 2018).

We have started detecting large and uncontrolled fires in the drier ecosystems of Bolivia, but outside the Amazon watershed.

Key Examples of 2020 Fires

Overall our key finding is that most major Brazilian Amazon fires are burning recently deforested areas, and not raging forest fires. Below is a series of four satellite images time-lapse videos showing examples of recent deforestation (2019) followed by a major 2020 fire burning lots of biomass that was detected by the app.

As presented in MAAP #118, Amazon Conservation launched a real-time fire monitoring app that specializes in the rapid and user-friendly detection and visualization of major Amazon fires.

In a novel approach, the app combines data from the atmosphere (aerosol emissions in smoke) and the ground (heat anomalies) to effectively monitor large Amazon fires.

2020 Amazon major fire #12, in Mato Grosso Brazil, on June 29. Data: Planet. Analysis: MAAP/Amazon Conservation.

As detailed below, the app just detected the 12th major Amazon fire of the year on June 29, 2020 (see the high-resolution image to the right).

It burned 587 hectares (1,451 acres) of land deforested in 2019.

Thus far, all 12 major Amazon fires of 2020 have:

• Occured in the state of Mato Grosso, in the southeastern Brazilian Amazon.
• Burned recently deforested areas (that is, areas deforested in 2018, 2019, or 2020). In other words, these are not forest fires. See MAAP #113 for background on this important point.

Below, we describe the process of using the app to detect and confirm the fire on June 29.

Step 1.

Detection of elevated emissions in the southeastern Brazilian Amazon (Mato Grosso).

Step 2.

Zoom in to confirm the elevated aerosol emissions, indicating the burning of abundant biomass.

Step 3.

Adjust the transparency to see the underlying fire alerts that indicate the exact location of the fires. Obtain coordinates of the source of the fires.

Step 4.

Confirm fire with satellite imagery. For example, here is a high resolution image from Planet Explorer showing the fire burning on June 29.

Step 5.

Using Planet’s extensive imagery archive, we were able to determine that the fires were burning an area deforested in 2019 (and not a forest fire). In the timelapse below, see that the deforestation occurred between September and October 2019, and then burned on June 29, 2020. The final image shows the day after the fires, June 30, to see the full extent of the burn.
