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).

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.

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

Amazon Conservation’s sister organization Conservación Amazónica – ACCA, with support from Google.org, just finished up a two-year initiative that trained community members to use cutting-edge satellite and field technologies to combat deforestation in the southern Peruvian Amazon, now protecting over 150,000 acres of lowland forests.
Before this program, concessionaires and their communities lacked capacity to monitor these large, remote areas and a way to rapidly and safely report deforestation in their territories. Our innovative methodology of combining real-time satellite imagery analysis and drone field technology (which includes smartapps and other technologies developed by Google) with legal training, gave concessionaires the ability to detect and report deforestation as it happened in their territory. This is a stark contrast from before, when the only way to monitor thousands of acres of forests was through foot patrols that took days to complete.
Through this program, over 153,000 acres (62,000 hectares) of forests are now monitored and protected with technology by the local people we empowered. Moreover, technological kits were donated to each individual or local association, each containing a drone, a maintenance kit, a laptop and a printer, giving them the knowledge and tools needed to safeguard forests..
The project, led by our director of our Southwest Amazon Drone Center, Carlos Castañeda, will continue to provide technical support to maintain the donated drones and training to reinforce what they learned, as well as be available to answer any questions that may arise during monitoring and surveillance of their concessions. Thus, the continuity of the project and its sustainability are ensured.

For the past year our team in Bolivia and Peru have been working with EUROCLIMA+, an initiative of the European Commission focused on combating climate change in Latin America. We are working with local communities to pilot climate change resilience in their sustainable use of forest resources.
n Bolivia, coordinates this project. His team works in the northern part of Bolivia, where local communities heavily depend on these forest goods to make a living. “Almost all the families dedicate themselves to harvesting forest fruits, mainly the Brazil nut, which is their main economic activity.”
Tying the importance of conservation of these forests not only to climate change but also to economic sustainability of local and global economies is vital for countries and communities to see the value of forests. In fact, our area of work in Bolivia holds 85% of the Brazil nut production in the world, and keeping those forests standing through sustainable activities will have a significant impact in the fight against deforestation and carbon emissions.
A key aspect of our work with EUROCLIMA+ is recognizing how these sustainable forest economies help mitigate the effects of climate change on communities and on the planet, which hadn’t previously been as much on peoples’ minds. This pilot work is also helping local communities become aware of how climate is changing the forests on which they depend, so they can plan for their long-term, sustainable use, without needing to turn to destructive practices like timber extraction and cattle ranching if a harvesting season is affected by global warming. This involves not only making sure we have healthy forests, but also helping communities diversify their source of income sustainably, such as harvesting other complementary forest products like açaí berries and sustainably farming paiche fish.
The Escazú Agreement, a regional agreement on access to information, public participation and access to justice in environmental matters in Latin America and the Caribbean whose ratification is soon to be debated in Congress, has generated an intense reaction and discussion. There is a sector that affirms that this agreement would attempt against our sovereignty in the Amazon. Considering that if this agreement is ratified, the important decisions for the economic development of the country would remain in the hands of international spheres. On the other hand, others consider that such an agreement leads to improved information flow and citizen participation. Both are necessary for the development of the country, particularly in Peru where social and environmental conflicts have paralyzed many important works for the economy. Understanding the scope of the agreement and its true implications is crucial for the future of Peru.
How can the Escazú Agreement threaten national sovereignty, and in particular, with our Amazon? To begin with, this is a Latin American regional agreement, which has been signed by 22 democratic nations (including those Amazonian), and so far, has been ratified by 9 of them. The agreement clearly states that decisions are the affairs of each country, within their own regulatory frameworks. It also stipulates that in cases where the conflict is between States, these – and only under a bilateral agreement – can be submitted to arbitration by the International Court of The Hague, as an international instance. That court does not have jurisdiction for internal affairs of a country, such as those between private, communities and the State. The resolution of controversies within a country is another matter, and only after exhausting the national justice mechanisms, they can be resolved by resorting to international bodies, which have nothing to do with the Escazú agreement.







seedlings mixed with biochar. The first 1,250 seedlings were transplanted to a target area of 2.1 hectares (5.2 acres), which had been verified as an ideal area for restoration through reforestation using this species. A tractor and a short boat trip down the river helped bring the seedlings to their new home, where they were planted throughout the end of 2019.
