Amazon Fire Tracker 2021: Brazilian Amazon Fire Season Begins

Posted on by dcadmin
2021 Brazilian Amazon Fire #2. Mato Grosso. Data: MAAP, Planet.

Last year (2020), we demonstrated the power of our real-time Amazon fire monitoring app (see MAAP #118 and MAAP #129).

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

Using the app, we just detected the first two major fires in the Brazilian Amazon for 2021.

These fires occurred on May 19 and 20, respectively, both on the southern edge of the Amazon in the state of Mato Grosso. For comparison, last year’s intense fire season started on May 28.

We confirmed both fires using high-resolution imagery from the satellite company Planet.

Importantly, the imagery also revealed that both fires burned recently deforested areas. That is, instead of being actual “forest fires,” both areas were actually first deforested in 2020 and then burned in 2021. See MAAP #113 for background on this important point.

Below, we show a striking series of satellite imagery videos showing this critical process of Amazon deforestation followed by Amazon fires.

2021 Brazilian Amazon Fire #1

We detected the first major fire of the year in the Brazilian Amazon on May 19, on the southern edge of the Amazon in the state of Mato Grosso. As the satellite video shows, this area was first cleared in 2020 and then later burned in 2021.

2021 Brazilian Amazon Fire #2

We detected the second major fire of the year in the Brazilian Amazon the following day, on May 20, also on the southern edge of the Amazon in the state of Mato Grosso. As the satellite video shows, this area was also first cleared in 2020 and then later burned in 2021.

*App Background

We launched a new and improved version of the Amazon real-time fire monitoring app in May 2021. The app is hosted by Google Earth Engine and updated every day by the organization Conservación Amazónica, based in Peru.

The app displays aerosol emissions as detected by the European Space Agency’s Sentinel-5 satellite. Elevated aerosol levels indicate the burning of 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 (aerosol definition: Suspension of fine solid particles or liquid droplets in air or another gas). 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). The spatial resolution of the aerosol data is 7.5 sq km. The high values in the aerosol indices (AI) may also be due to other reasons such as emissions of volcanic ash or desert dust so it is important to cross reference elevated emissions with heat data and optical imagery.

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.

Since the data updates daily and is not impacted by clouds, real-time monitoring really is possible. Our goal is to upload each day’s new image in the late afternoon/early evening.

In January, we presented the first look at 2020 Amazon deforestation based on early warning alert data (MAAP #132).

Here, we update this analysis based on the newly released, and more definitive, annual data.*

The Base Map illustrates the final results and indicates the major hotspots of primary forest loss across the Amazon in 2020.

We highlight several key findings:

  • The Amazon lost nearly 2.3 million hectares (5.6 million acres) of primary forest loss in 2020 across the nine countries it spans.
    g
  • This represents a 17% increase in Amazon primary forest loss from the previous year (2019), and the third-highest annual total on record since 2000 (see graph below).
    j
  • The countries with the highest 2020 Amazon primary forest loss are 1) Brazil, 2) Bolivia, 3) Peru, 4) Colombia, 5) Venezuela, and 6) Ecuador.
    h
  • 65% occurred in Brazil (which surpassed 1.5 million hectares lost), followed by 10% in Bolivia, 8% in Peru, and 6% in Colombia (remaining countries all under 2%).
    k
  • For Bolivia, Ecuador, and Peru, 2020 recorded historical high Amazon primary forest loss. For Colombia, it was the second highest on record.

In all of the data graphs, orange indicates the 2020 primary forest loss and red indicates all years with higher totals than 2020.

For example, the Amazon lost nearly 2.3 million hectares in 2020 (orange), the third highest on record behind only 2016 and 2017 (red).

Note that the three highest years (2016, 2017, and 2020) had one major thing in common: uncontrolled forest fires in the Brazilian Amazon.

See below for country-specific graphs, key findings, and satellite images for the top four 2020 Amazon deforestation countries (Brazil, Bolivia, Peru, and Colombia).

 

 

 

Brazilian Amazon

2020 had the sixth-highest primary forest loss on record (1.5 million hectares) and a 13% increase from 2019.

Many of the 2020 hotspots occurred in the Brazilian Amazon, where massive deforestation stretched across nearly the entire southern region.

A common phenomenon observed in the satellite imagery through August was that rainforest areas were first deforested and then later burned, causing major fires due to the abundant recently-cut biomass (Image A). This was also the pattern observed in the high-profile 2019 Amazon fire season. Much of the deforestation in these areas appears to associated with expanding cattle pasture areas.

In September 2020 (and unlike 2019), there was a shift to actual Amazon forest fires (Image B). See MAAP #129 for more information on the link between deforestation and fire in 2020.

Note that the three highest years (2016, 2017, and 2020) had one major thing in common: uncontrolled forest fires in the Brazilian Amazon.

Image B. Forest fire in Brazilian Amazon (Para state) that burned 9,000 hectares between March (left panel) and October (right panel) 2020. Data: Planet.

Bolivian Amazon

2020 had the highest primary forest loss on record in the Bolivian Amazon, surpassing 240,000 hectares.

Indeed, the most intense hotspots across the entire Amazon ocurred in southeast Bolivia, where fires raged through the drier Amazon forests (known as the Chiquitano and Chaco ecosystems).

Image C shows the burning of a massive area (over 260,000 hectares) in the Chiquitano dry forests (Santa Cruz department).

Peruvian Amazon

2020 also had the highest primary forest loss on record in the Peruvian Amazon, surpassing 190,000 hectares.

This deforestation is concentrated in the central region. On the positive, the illegal gold mining that plagued the southern region has decreased thanks to effective government action (see MAAP #130).

Image D shows expanding deforestation (over 110 hectares), and logging road construction (3.6 km), in an indigenous territory south of Sierra del Divisor National Park in the central Peruvian Amazon (Ucayali region). The deforestation appears to be associated with an expanding small-scale agriculture or cattle pasture frontier.

Colombian Amazon

2020 had the second-highest primary forest loss on record in the Colombian Amazon, nearly 140,000 hectares.

As described in previous reports (see MAAP #120), there is an “arc of deforestation” concentrated in the northwest Colombian Amazon. This arc impacts numerous protected areas (including national parks) and Indigenous Reserves.

For example, Image E shows the recent deforestation of over 500 hectares in Chiribiquete National Park. Similar deforestation in that sector of the park appears to be conversion to cattle pasture.

*Notes and Methodology

To download the report, click “Print” instead of “Download PDF” at the top of the page.

The analysis was based on 30-meter resolution annual data produced by the University of Maryland (Hansen et al 2013), obtained from the “Global Forest Change 2000–2020” data download page. It is also possible to visualize and interact with the data on the main Global Forest Change portal.

Importantly, this data detects and classifies burned areas as forest loss. Nearly all Amazon fires are human-caused. Also, this data does include some forest loss caused by natural forces (landslides, wind storms, etc…).

Note that when comparing 2020 to early years, there are several methodological differences from the University of Maryland introduced to data after 2011. For more details, see “User Notes for Version 1.8 Update.”

It is worth noting that we found the early warning (GLAD) alerts to be a good (and often conservative) indicator of the final annual data.

Our geographic range includes nine countries and consists of a combintion of the Amazon watershed limit (most notably in Bolivia) and Amazon biogeographic limit (most notably in Colombia) as defined by RAISG. See Base Map above for delineation of this hybrid Amazon limit, designed for maximum inclusion. Inclusion of the watershed limit in Bolivia is a recent change incorporated to better include impact to the Amazon dry forests of the Chaco.

We applied a filter to calculate only primary forest loss. For our estimate of primary forest loss, we intersected the forest cover loss data with the additional dataset “primary humid tropical forests” as of 2001 (Turubanova et al 2018). For more details on this part of the methodology, see the Technical Blog from Global Forest Watch (Goldman and Weisse 2019).

To identify the deforestation hotspots, we conducted a kernel density estimate. This type of analysis calculates the magnitude per unit area of a particular phenomenon, in this case forest cover loss. We conducted this analysis using the Kernel Density tool from Spatial Analyst Tool Box of ArcGIS. We used the following parameters:

Search Radius: 15000 layer units (meters)
Kernel Density Function: Quartic kernel function
Cell Size in the map: 200 x 200 meters (4 hectares)
Everything else was left to the default setting.

For the Base Map, we used the following concentration percentages: Medium: 7-10%; High: 11-20%; Very High: >20%.

MAAP #133: Deforestation Continues in National Parks of Colombian Amazon

Posted on by dcadmin
Base Map. Deforestation 2020-21 in the National Parks of the Colombian Amazon. Data: MAAP.

As we have indicated in previous reports (MAAP #120), there is an “arc of deforestation” in the northwest Colombian Amazon, impacting numerous protected areas and indigenous reserves.

Here, we emphasize that this deforestation currently impacts four National Parks: Tinigua, Macarena, Chiribiquete and La Paya.

In the Base Map, the red circles indicate the areas most impacted by recent deforestation within these parks.

The letters (A-D) indicate the location of the high-resolution satellite images (Planet) below.

While Tinigua and Macarena continue as the most impacted National Parks, below we focus on the new deforestation fronts in Chiribiquete and La Paya.

Specifically, we show the most recent and urgent deforestation, since September 2020 to the present (February 2021).

 

 

 

 

Chiribiquete National Park

Chiribiquete National Natural Park lost more than 1,000 hectares (2,500 acres) in the last six months, in six different areas of the park (see Base Map above). Much of this deforestation appears to be associated with the conversion of primary forest to illegal cattle pasture. The following satellite images show deforestation in three of these areas (A-C) between September 2020 (left panel) and February 2021 (right panel). *It is important to note that immediately prior to this publication authorities carried out a major intervention to crack down on the illegal activity within the park (see news here).

Fire Season

In addition, the fire season has started in the Colombian Amazon. Interestingly, now (February to March) is typically Colombia’s peak deforestation and fire season, in contrast with Brazil, Bolivia, and Peru, whose seasons peak between June and October.

MAAP #129: Amazon Fires 2020 – Recap of Another Intense Fire Year

Posted on by dcadmin
Base Map. Major Amazon fires 2020 (orange dots) within Amazon watershed (blue line). Data: MAAP.

Following the intense Amazon fire season of 2019 that made international headlines, here we report another major fire year in 2020.

Using the novel data from our real-time Amazon Fires Monitoring app,* we documented over 2,500 major fires across the Amazon in 2020 (see Base Map).

The vast majority (88%) of the major fires were in the Brazilian Amazon, followed by the Bolivian Amazon (8%) and Peruvian Amazon (4%). No major fires were detected in the other Amazonian countries.*

We highlight several major headlines:

  • In the Brazilian Amazon, we detected 2,250 major fires. Most (51%) burned recently deforested areas, defined as fires in areas previously cleared between 2018 and 2020. These fires burned an estimated 1.8 million acres, emphasizing the current high deforestation rates in Brazil. In September, there was a major spike in forest fires, impacting vast areas of standing forest (over 5 million acres).
    m
  • In the Bolivian Amazon, we detected 205 major fires. The vast majority (88%) burned in Amazonian savanna and dry forest ecosystems. Notably, a quarter of these fires burned within protected areas.
    ,
  • In the Peruvian Amazon, we detected 116 major fires. There were three major types: 41% burned high elevation grasslands (impacting 26,000 acres), 39% burned recently deforested areas, and 17% burned standing forest (impacting 6,700 acres).
    v
  • The vast majority of the major fires across all three countries were likely human-caused and illegal, in violation of governmental fire management regulations and moratoriums.
    k
  • The app was only fully implemented in 2020, so we do not have comparable data for 2019. However, our extensive analysis of satellite imagery indicates that, in the Brazilian Amazon, both 2019 and 2020 had in common the extensive burning of recently deforested areas. The late season shift to forest fires seemed much more intense in 2020. In the Bolivian Amazon, both 2019 and 2020 had in common the extensive burning of Amazon savannas and dry forests.

See below for additional and more detailed findings for each country. Also, check out Mongabay’s real-time Brazilian Amazon fire tracker based on our analysis.

Brazilian Amazon

Image 1. Major fire burning recently deforested area in Brazilian Amazon (Mato Grosso). Data: Planet.

We emphasize the following additional findings for the Brazilian Amazon:

  • Of the 2,250 major fires, over half (51%) burned recently deforested areas, defined as areas where the forest was previously cleared between 2018 and 2020 prior to burning (Image 1). These fires burned an estimated 1.8 million acres (742,000 hectares), highlighting the current high deforestation rates in Brazil.
    .
  • A striking number (40%) were forest fires, defined here as human-caused fires in standing forest. A rough initial estimate suggests that 5.4 million acres (2.2 million hectares) of Amazon forest burned.
    .
  • Over half (51%) occurred in September, followed by August and October (25% and 15%, respectively). September was also when we documented a major shift from fires in recently deforested areas to forest fires.
    .
  • An important number of major fires (12%) occurred within indigenous territories and protected areas. The most impacted were Xingu and Kayapó Indigenous Territories, Jamanxim National Forest, and Nascentes da Serra do Cachimbo Biological Reserve.
    .
  • The vast majority of the major fires (97%) appear to be illegal, occurring after the Amazon fire moratoriums established in July (the government established a 4-month national fire moratorium starting July 15).
    ,
  • Pará  (38%) and Mato Grosso (31%) states had the most fires, followed by Amazonas (15%), Rondônia (11%), and Acre (4%).

Bolivian Amazon

Image 2. Major fire in Noel Kempff Mercado National Park, in the Bolivian Amazon. Data: Planet.

We emphasize the following additional findings for the Bolivian Amazon:

  • Of the 2015 major fires, many (46%) occurred in Amazon savannas.
    .
  • Another 42% of the fires were located in forests, mostly in the dry forests of the Chiquitano. Note, in November there was a major spike in these fires.
    .
  • Importantly, 25% of the major fires were in protected areas. The most impacted were Noel Kempff Mercado National Park (Image 2), Copaibo Municipal Protected Area, Iténez National Park, Keneth Lee Reserve, Rios Blanco y Negro Wildlife Reserve, and Pampas del Río Yacuma Integrated Management Natural Area.
    k
  • The vast majority of the fires (96%) were likely illegal, occuring after the fire moratoriums (August 3 in Beni and Santa Cruz, followed by October 5 nationally).
    .
  • Most of the fires occurred in the department of Beni (51%), followed by Santa Cruz (46%).
    .
  • August had the most fires (27%) followed closely by each of September, October, and November (24% each).
    h

Peruvian Amazon

Image 3. Major fire in higher elevation grassland of the Peruvian Amazon. Data: Planet.

We emphasize the following additional findings for the Peruvian Amazon:

  • Of the 116 major fires, many (39%) burned recently deforested areas. Although the pattern is similar to the Brazilian Amazon, the burned (and previously deforested) areas are much smaller (4,660 vs 1.8 million acres).
    ,
  • There were also numerous major fires (41%) in higher elevation grasslands across several regions (Image 3). These fires impacted 26,000 acres (10,000 hectares). We likely underestimated the number of these fires because, due to the lack of biomass in these ecosystems, they didn’t always register as a major fire in the app.
    k
  • Another 17% were forest fires, impacting 6,700 acres (2,700 hectares).
    k
  • All of the fires in the Peruvian were likely illegal, according to Peruvian fire management regulations.
    j
  • 15 regions experienced major fires, reflecting the mix of both grassland and forest fires. The regions with the most fires were Madre de Dios (23%), Ucayali (12%) and Junin (11%).
    h
  • November surprisingly had the most major fires (46%), followed by October and September (29% and 22%, respectively).
    j

*Notes and Methodology

The data is based on our analysis of Amazon Conservation’s novel real-time Amazon Fires Monitoring app. We started daily monitoring in May and continued through November. Specifically, he first major fire was detected on May 28 and the data was updated daily through November 30.

The app displays aerosol emissions as detected by the European Space Agency’s Sentinel-5 satellite. Elevated aerosol levels indicate the burning of 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 (aerosol definition: Suspension of fine solid particles or liquid droplets in air or another gas). 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). The spatial resolution of the aerosol data is 7.5 sq km. The high values in the aerosol indices (AI) may also be due to other reasons such as emissions of volcanic ash or desert dust so it is important to cross reference elevated emissions with heat data and optical imagery.

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.

Some additional country-specific notes:

Bolivia – As note above, the high values in the aerosol indices (AI) may also be due to other reasons such as emissions of volcanic ash or desert dust. Hence, some areas, such as the Salar de Uyuni, in western Bolivia, often have orange or red tones.

Colombia – Our daily 2020 monitoring took place from May until November, but Colombia’s drier burning season was likely earlier in the year (January – March). We will be monitoring Colombia during this time frame in 2021.

MAAP: Fires in the Bolivian Amazon 2020

Posted on by dcadmin
Base Map. Major fires in the Bolivian Amazon during 2020. Data: MAAP/ACEAA.

We have detected 120 major fires this year in the Bolivian Amazon, as of the first of October (see Base Map).*

The majority of these fires (54%) occurred in savannas, located in the department of Beni.

Another 38% of the major fires were located in forests, mostly in the dry forests of the Chiquitano.

We emphasize that 25% of the major fires were located in Protected Areas (see below)..

*The data, updated through October 1, is based on our novel real-time Amazon Fires Monitoring app, which is based on the detection of elevated aerosol emissions (by the European Space Agency’s Sentinel-5 satellite) that indicate the burning of large amounts of biomass (defined here as a “major fire”).

Amazon Fire Season Intensifies; Shifts to Raging Forest Fires

Posted on by dcadmin
Forest Fire in the Brazilian Amazon (Mato Grosso). Data: Planet.

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.”

Brazilian Amazon Fires Intensify in September

Posted on by dcadmin
Base Map. Amazon fires in relation to Pantanal fires as seen in our Real-time Amazon Fire Monitoring app (September 6). Red indicates most severa fires. Data: MAAP/ACCA.

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.

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 vast majority of the major fires (79%) continue to burn recently deforested areas, defined here as areas where the forest was previously and recently cleared (between 2018-20) prior to burning.
p
In fact, over 1.1 million acres (453,000 hectares) of recently deforested areas has burned in 2020. Thus, the fires are actually a smoking indicator of the current rampant deforestation in the Brazilian Amazon.

Amazon Fire Tracker 2020: Over 500 Illegal Major Fires in Brazilian Amazon

Posted on by dcadmin

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).

Some striking stats about this year’s major fires:

  • 97% have occured after the burning moratoriums established in July and are illegal.
    l
  • 85% have occurred in August. Thus, the fire season has been accelerating.
    p
  • 83% have burned recently deforested areas. Thus, the fires are actually a smoking indicator of the rampant deforestation.
    p
  • 12% have been Forest Fires. This number marks a major increase from previous estimate as the fire season intensifies. By “Forest Fire” we mean human caused fires in standing forest (there are no “wildfires” as we understand the situation).
    p
  • 4% have occurred in Protected Areas or Indigenous Territories.
    p
  • 856,000 acres (353,000 hectares) have burned in the recently deforested areas fires.
  • 165,000 acres (66,000) have burned in the forest fires.

Base Map

The Base Map is a screen shot of the app’s “Major Amazon Fires 2020” layer. The majority of the major fires in the Brazilian Amazon have been in the states of Pará (42%) and Amazonas(31%), followed by Mato Grosso (13%) and Rondônia (13%). Note we are also now seeing an increase in major fires in the Bolivian Amazon, particularly savannah fires, and that will be the subject of a future report.

Amazon Fire Tracker 2020: Images of the Brazilian Amazon Fires

Posted on by dcadmin

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.
