2022 Amazon Forest Loss Base Map. Deforestation and fire hotspots across the full Amazon biome. Data: UMD/GLAD, ACA/MAAP.

We present a detailed look at the major 2022 Amazon forest loss hotspots, based on the final annual data recently released by the University of Maryland (and featured on Global Forest Watch).

This dataset is unique in that it is consistent across all nine countries of the Amazon, and distinguishes forest loss from fire, leaving the rest as a proxy for deforestation (but also includes natural loss).

Thus, we are able to present both deforestation and fire hotspots across the Amazon.

The Base Map (see right) and Results Graph (see below) reveal several key findings:

  • In 2022, we estimate the deforestation of 1.98 million hectares (4.89 million acres). This represents a major 21% increase from 2021, and is the second highest on record, behind only the peak in 2004.
    k
  • Deforestation hotspots were especially concentrated along roads in the Brazilian Amazon, the soy frontier in the southeast Bolivian Amazon, and near protected areas in northwest Colombian Amazon.
    k
  • The vast majority of the deforestation occurred in Brazil (72.8%), followed by Bolivia (12.4%), Peru (7.3%), and Colombia (4.9%). Note that deforestation in Bolivia was the highest on record, and in Brazil the highest since the early 2000s.
    k
  • Fires impacted an additional 491,223 hectares (1.2 million acres) of primary forest. This total represents a 1.6% increase from 2021, and the 4th highest on record (behind only intense fire seasons of 2016, 2017, and 2020). Moreover, each of the seven most intense fire seasons has occurred in the past seven years. Nearly 93% of the fire impact occurred in just two countries: Brazil and Bolivia.
    k
  • In total, 2.47 million hectares (6.1 million acres) of primary forest were impacted by deforestation and fire. This total represents the third highest on record, only behind the post-El Niño years of 2016 and 2017.
    k
  • Since 2002, we estimate the deforestation of 30.7 million hectares (75.9 million acres) of primary forest, greater than the size of Italy or the U.S. state of Arizona.

Below, we zoom in on the six countries with the highest deforestation (Brazil, Bolivia, Peru, Colombia, Ecuador, and Venezuela) with additional maps and analysis.

Amazon Primary Forest Loss (By Country), 2002-2022

Brazilian Amazon

Brazil Base Map, 2022. Deforestation and fire hotspots in the Brazilian Amazon in relation to major roads. Data: UMD/GLAD, ACA/MAAP.

In 2022, the Brazilian Amazon lost 1.4 million hectares (3.56 million acres) of primary forest to deforestation. Fires directly impacted an additional 348,824 hectares.

The deforestation rose 20.5% from 2021, and was the highest on record since the peak years of 2002 – 2005.

The fire impact was the 4th highest on record, only behind the intense fire years of 2016, 2017, and 2020.

The deforestation was concentrated along the major road networks, especially roads 230 (Trans-Amazonian Highway), 364, 319, and 163 in the states of Amazonas, Pará, Rondônia, and Acre (see Brazil Base Map).

The direct fire impacts were concentrated in the soy frontier, located in southeastern state of Mato Grosso

 

 

 

 

 

 

Bolivian Amazon

Bolivia Base Map, 2022. Deforestation and fire hotspots in Bolivian Amazon. Data: UMD/GLAD, ACA/MAAP.

In 2022, the Bolivian Amazon lost 245,177 hectares of primary forest to deforestation. Fires directly impacted an additional 106,922 hectares.

We highlight that this deforestation was 47% higher than 2021, and the highest on record (by far).

The fire impact was also up from last year, and the second-highest on record behind just the intense year of 2020.

Both the deforestation and fires were concentrated in the soy frontier located in southeastern department of Santa Cruz (see Bolivia Base Map).

 

 

 

 

 

 

 

 

 

 

Peruvian Amazon

Peru Base Map, 2022. Deforestation and fire hotspots in the Peruvian Amazon. Data: UMD/GLAD, ACA/MAAP.

In 2022, the Peruvian Amazon lost 144,682 hectares of primary forest to deforestation. Fires directly impacted an additional 16,408 hectares.

Deforestation increased 6.7% from 2021, and was the 5th highest on record. Fire impact decreased from last year, but was still relatively high.

The deforestation was concentrated in the central and southern Amazon (Ucayali and Madre de Dios regions, respectively) (see Peru Base Map).

In the central Amazon, we highlight the rapid deforestation for a new Mennonite colony (see MAAP #166).

In the southern Amazon, gold mining deforestation continues to be an issue in indigenous communities and within the official Mining Corridor.

 

 

 

 

 

 

 

Colombian Amazon

Colombia Base Map, 2022. Deforestation and fire hotspots in northwest Colombian Amazon. Data: UMD/GLAD, ACA/MAAP, FCDS.

In 2022, the Colombian Amazon lost 97,417 hectares of primary forest to deforestation. Fires directly impacted an additional 12,880 hectares.

Deforestation decreased 2% from 2021, but it was still relatively high (5th highest on record), continuing the trend of elevated forest loss since the FARC peace agreement in 2016.

Fire impact increased from last year and was actually the highest on record, edging out 2018 and 2019.

As described in previous reports (see MAAP #120), the Colombia Base Map shows there continues to be an “arc of deforestation” in the northwest Colombian Amazon (Caqueta, Meta, and Guaviare departments).

This arc impacts numerous Protected Areas (particularly Tinigua and Chiribiquete National Parks) and Indigenous Reserves (particularly Yari-Yaguara II and Nukak Maku).

 

 

 

 

Ecuadorian Amazon

Ecuador Base Map, 2022. Deforestation and fire hotspots in the Ecuadorian Amazon. Data: UMD/GLAD, ACA/MAAP.

Although accounting for just 1% of total loss across the Amazon, deforestation in the Ecuadorian Amazon was the highest on record in 2022 (18,902 hectares), up a striking 80% since 2021.

There are several deforestation hotspots caused by gold mining (see MAAP #182), oil palm plantation expansion, and small-scale agriculture.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Venezuelan Amazon

In the Venezuelan Amazon, deforestation was on par with last year (12,584 hectares).

There is a deforestation hotspot caused by gold mining in Yapacana National Park (see MAAP #173, MAAP #156, MAAP #169).

There are also hotspots in the Orinoco Mining Arc caused by mining and agriculture.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Methodology

The analysis was based on 30-meter resolution annual forest loss data produced by the University of Maryland and also presented by Global Forest Watch.

This data was complemented with the Global Forest Loss due to fire dataset that is unique in terms of being consistent across the Amazon (in contrast to country specific estimates) and distinguishes forest loss caused directly by fire (note that virtually all Amazon fires are human-caused). The values included were ‘medium’ and ‘high’ confidence levels (code 3-4).

The remaining forest loss serves as a likely close proxy for deforestation, with the only remaining exception being natural events such as landslides, wind storms, and meandering rivers. The values used to estimate this category was ‘low’ certainty of forest loss due to fire (code 2), and forest loss due to other ‘non-fire’ drivers (code 1).

For the baseline, it was defined to establish areas with >30% tree canopy density in 2000. Importantly, we applied a filter to calculate only primary forest loss by intersecting 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).

Our geographic range for the Amazon is a hybrid designed for maximum inclusion: biogeographic boundary (as defined by RAISG) for all countries, except for Bolivia and Peru, where we use the watershed boundary, and Brazil, where we use the Legal Amazon boundary.

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 the 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: High: 3-14%; Very High: >14%.

Amazon Base Map. Forest Carbon Flux across the Amazon, 2001-2020. Data: Harris et al 2021. Analysis: Amazon Conservation/MAAP.

We present here the first report of a series focused on the Venezuelan Amazon, which covers over 47 million hectares of the northern section of the Amazon biome (above western Brazil).

As the Amazon Base Map indicates, Venezuela is a key part to the remaining core Amazon that is still functioning as a critical carbon sink, making it an important piece to long-term conservation strategies.

However, deforestation has been increasing in recent years (see graph in Base Map), indicating escalating threats.

Specifically, there is a clear trend of increasing primary forest loss since 2015, including a recent spike in 2019.

We estimate the loss of over 140,000 hectares (345,000 acres) over the past four years, accounting for 1.6% of the total loss across the Amazon during that time period.

Below, we investigate the major hotspots and drivers of deforestation currently in the Venezuelan Amazon.

 

 

Venezuela Base Map. Hotspots of primary forest loss across the Venezuelan Amazon (2017-2020). UMD/GLAD, MAAP.

The Venezuela base map shows the major hotspots of primary forest loss across the Venezuelan Amazon over the past four years (2017-2020).

Note that most hotspots are within the Orinoco Mining Arc, a large area over 11 million hectares created by a controversial presidential decree in 2016 designed to promote mining (SOSOrinoco 2021), as well as within and around the extensive network of protected areas.

These protected areas cover 43% (20 million hectares) of the Venezuelan Amazon and accounted for around 30% of total forest loss. The most impacted areas in recent years are Caura, Canaima, and Yapacana National Parks (over 22,000 hectares combined).

We zoomed in on these hotspots and found that mining, fires, and agriculture (including cattle pasture) are the three primary deforestation drivers across the Venezuelan Amazon. There may be complex interactions between these drivers, such as mining centers leading to fires and agricultural expansion to support the new mining population.

It is worth noting that Venezuela joins Peru, Brazil, and Suriname as countries where mining is now documented to be actively driving major deforestation of primary forest.

We also note that, as in the rest of the Amazon, virtually all fires are caused by humans (that is, not natural events) and most are likely linked to preparing land for agricultural activities. During drier periods, these fires may escape, causing larger forest fires.

Below, we illustrate these drivers in a series of high-resolution (3 meters) and very high-resolution (0.5 meters) images.

High-resolution Zooms

Mining

Zoom A. Yapacana National Park

Yapacana National Park, which is a unique mosaic of natural savannas and forest, is currently experiencing deforestation impacts from active mining operations. We show two examples of recent mining in the Cerro Yapacana mining sector, featuring very-high resolution imagery from late 2021 (see Zooms A1 and A2). These two areas have lost over 550 hectares since the early 2000s.

Methodology

For a study area with maximum inclusion, for the Venezuelan Amazon we used the wider biogeographic boundary (as defined by RAISG) rather than the strict Amazon watershed boundary (which actually only includes a small portion of Venezuela).

We obtained data for the Orinoco Mining Arc (Arco Minero del Orinoco) and protected areas from the organization SOSOrinoco. The latter dataset contains Areas Under Special Administration Regime (Áreas Bajo Régimen de Administración Especial – ABRAE), which meet the IUCN international definition of protected areas: national parks, natural monuments, wildlife refuges, reserves and sanctuaries.

We used “primary forest loss” data as our proxy for 2002-2020 annual deforestation. This 30-meter resolution (based on Landsat) data is produced by the University of Maryland and presented by Global Forest Watch. Note that it includes forest loss from fires and natural causes. 2021 early warning alert data is also from University of Maryland.

To identify primary forest loss 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.

Finally, we investigated the major hotspots with both high resolution (3 meters) and very high resolution (0.5 meters) satellite imagery from the company Planet to identify causes (drivers).

2021 Amazon Forest Loss Base Map. Deforestation and fire hotspots across the full Amazon biome. Data: UMD/GLAD, ACA/MAAP.

We present a detailed look at the major 2021 Amazon forest loss hotspots, based on the final annual data produced by the University of Maryland.

This dataset is unique in that distinguishes forest loss from fire, leaving the rest as a close proxy for deforestation.

Thus, for the first time, the results include both deforestation and fire hotspots across the Amazon.

The Base Map (see right) and Results Graph (see below) reveal several key findings:p

  • In 2021, we estimate the loss of 2 million hectares (4.9 million acres) of primary forest loss across the nine countries of the Amazon biome. This total represents a slight decrease from 2020, but the 6th highest on record.
    l
  • The vast majority of this loss was deforestation (78%), accounting for 1.57 million hectares. This total represents a slight increase from 2020, and the 5th highest on record. This deforestation impacted the entire stretch of the southern Amazon (southern Brazil, Bolivia, and Peru) plus further north in Colombia.
    l
  • This deforestation was concentrated in Brazil (73%), Bolivia (10%), Peru (8%), and Colombia (6%). In Brazil and Bolivia, deforestation was the highest since 2017. In Peru and Colombia, deforestation dropped from 2020 but was still historically high. See below for maps and graphs for each country. See Annex for 2020-21 details.
    k
  • Fires directly caused the remaining primary forest loss (22%), accounting for 436,000 hectares. This total represents a decrease from the severe fire season of 2020, but was the 4th highest on record. Moreover, each of the six most intense fire seasons has occurred in the past six years. Over 90% of the fire impact occurred in just two countries: Brazil and Bolivia. Note that fire impacts were concentrated in the southeast of each country (Mato Grosso and Santa Cruz states, respectively).
    k
  • Since 2002, we estimate the deforestation of over 27 million hectares (67 million acres) of primary forest, greater than the size of the United Kingdom or the U.S. state of Colorado. On top of this, we estimate an additional impact of 6.7 million hectares due to fires.

Below, we zoom in on the four countries with the highest deforestation (Brazil, Bolivia, Peru, and Colombia), with additional maps and analysis.

Amazon Forest Loss Results Graph, 2002-21. Data: UMD/GLAD, ACA/MAAP.

For deforestation, note that in 2021 there was a slight increase across the Amazon, continuing a gradual four-year trend. 2021 had the 5th highest deforestation on record (behind just 2002, 2004, 2005, and 2017).

For fire, in 2021 there was a decrease from the severe fire season of 2020, but was the 4th highest on record (behind just 2016, 2017, and 2020). Moreover, each of the last six years is in the top six worst fire seasons across the Amazon.

For total forest loss (deforestation and fire combined), in 2021 there was slight decrease from 2020, but the 6th highest on record.

Brazil Base Map, 2021. Deforestation and fire hotspots in the Brazilian Amazon. Data: UMD/GLAD, ACA/MAAP.

Brazilian Amazon

In 2021, the Brazilian Amazon lost 1.1 million hectares of primary forest to deforestation. Fires directly impacted an additional 293,000 hectares.

The deforestation was the highest since 2017 and also the peak of the early 2000s (6th highest on record). The fire impact was relatively high (5th highest on record), but less than the peak years of 2016, 2017, and 2020.

The deforestation was concentrated along the major road networks, especially roads 163, 230, 319, and 364 in the states of Acre, Amazonas, Pará, and Rondônia (see Brazil Base Map).

The direct fire impacts were concentrated in the southeastern state of Mato Grosso.

It is also important to note that many areas experienced the one-two combination of initial deforestation followed by fire to prepare the area for agriculture or cattle.

Bolivian Amazon

In 2021, the Bolivian Amazon lost 161,000 hectares of primary forest to deforestation. Fires directly impacted an additional 106,000 hectares.

Deforestation was the third-highest on record, just behind the peak in 2016 and 2017. The fire impact was the second-highest on record, behind just the intense year of 2020 (thus, the last two years are the two highest on record).

Both the deforestation and fires were concentrated in the southeastern department of Santa Cruz (see Bolivia Base Map).

Much of the deforestation was associated with large-scale agriculture, while the fires once again impacted important natural ecosystems, most notably the Chiquitano dry forests.

 

 

 

 

 

 

 

Peru Base Map. Deforestation hotspots in the Peruvian Amazon. Data: UMD/GLAD, ACA/MAAP.

Peruvian Amazon

In 2021, the Peruvian Amazon lost 132,400 hectares of primary forest to deforestation. Fires directly impacted an additional 21,800 hectares.

Deforestation dropped from a record high in 2020, but was 6th highest on record. Thre fire impact was the second-highest on record (behind just 2017).

The deforestation was concentrated in the central and southern Amazon (Ucayali and Madre de Dios regions, respectively) (see Peru Base Map).

We highlight the rapid deforestation (365 hectares) for a new Mennonite colony in 2021, near the town of Padre Marquez (see MAAP #149).

Also, note some additional hotspots in the south (Madre de Dios region), but these are largely from expanding agriculture instead of the historical driver of gold mining.

Indeed, gold mining deforestation has been greatly reduced due to government actions, but this illegal activity still threatens several key areas and indigenous territories (MAAP #154).

Colombia Base Map. Deforestation hotspots in northwest Colombian Amazon. Data: UMD/GLAD, ACA/MAAP, FCDS.

Colombian Amazon

In 2021, the Colombian Amazon lost 98,000 hectares of primary forest to deforestation. Fires directly impacted an additional 9,000 hectares.

Deforestation and fire dropped from last year, but both were the fourth highest on record, following the trend of elevated forest loss and associated fires since the peace agreement in 2016.

As described in previous reports (see MAAP #120), the Colombia Base Map shows there continues to be an “arc of deforestation” in the northwest Colombian Amazon (Caqueta, Meta, and Guaviare departments).

This arc impacts numerous Protected Areas (particularly Tinigua and Chiribiquete National Parks) and Indigenous Reserves (particularly Yari-Yaguara II and Nukak Maku).

The main drivers of deforestation in the Colombian Amazon are land grabbing, expansion of road networks, and cattle ranching.

Amazon Base Map. Deforestation hotspots across the Amazon in 2021 (as of September 18). Data: UMD/GLAD, ACA/MAAP.

We present a first look at the major 2021 Amazon deforestation hotspots.*

The Amazon Base Map illustrates several key findings:p

  • We estimate the loss of over 1.9 million hectares (4.8 million acres) of primary forest loss across the nine countries of the Amazon biome in 2021.
    k
  • This matches the previous two years, bringing the total deforestation to 6 million hectares (15 million acres) since 2019, roughly the size of the state of West Virginia.
    p
  • In 2021, most of the deforestation occurred in Brazil (70%), followed by Bolivia (14%), Peru (7%), and Colombia (6%).
    p
  • In Brazil, hotspots are concentrated along the major road networks. Many of these areas were also burned following the deforestation.
    j
  • In Bolivia, fires once again impacted several important ecosystems, including the Chiquitano dry forests.
    p
  • In Peru, deforestation continues to impact the central region, most notably from large-scale clearing for a new Mennonite colony.
    p
  • In Colombia, there continues to be an arc of deforestation impacting numerous protected areas and indigenous territories.

Below, we zoom in on the four countries with the highest deforestation (Brazil, Bolivia, Peru, and Colombia), with additional maps and analysis.

*Notes and Methodology

The analysis was based on 10-meter resolution primary forest loss alerts (GLAD+) produced by the University of Maryland and also presented by Global Forest Watch. These alerts are derived from the Sentinel-2 satellite operated by the European Space Agency.

We emphasize that this data represents a preliminary estimate and more definitive annual data will come later in the year.

We also note that this data does include forest loss caused by natural forces and burned areas.

Our geographic range for the Amazon is a hybrid between both the biogeographic boundary (as defined by RAISG) and watershed boundary, designed for maximum inclusion.

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.

Widespread Deforestation in the Brazilian Amazon

The Brazil Base Map shows the notable concentration of deforestation hotspots along the major roads (especially roads 163, 230, 319, and 364). Zooms A-C show high-resolution examples of this deforestation, which largely appears to be associated with clearing rainforests for pasture.

Arc of Deforestation in the Colombian Amazon

As described in previous reports (see MAAP #120), the Colombia Base Map shows there continues to be an “arc of deforestation” in the northwest Colombian Amazon (Caqueta, Meta, and Guaviare departments).

This arc impacts numerous protected areas (particularly Tinigua and Chiribiquete National Parks) and Indigenous Reserves (particularly Yari-Yaguara II and Nukak Maku).

Zooms D & E show high-resolution examples of this deforestation, which largely appears to be associated with clearing rainforests for pasture.

Deforestation in the central Peruvian Amazon

The Peru Base Map shows the concentration of deforestation in the central Peruvian Amazon (Ucayali, Huanuco, and southern Loreto regions).

Zooms F & G show two notable examples of this deforestation: the rapid deforestation in 2021 for a new Mennonite colony (299 hectares) and large-scale rice plantation (382 hectares), respectively.

Also note some additional hotspots in the south (Madre de Dios region) from gold mining and medium-scale agriculture.

The hotspot in the north (Loreto region) is natural forest loss from a windstorm.

*Notes and Methodology

The analysis was based on 10-meter resolution primary forest loss alerts (GLAD+) produced by the University of Maryland and also presented by Global Forest Watch. These alerts are derived from the Sentinel-2 satellite operated by the European Space Agency.

We emphasize that this data represents a preliminary estimate and more definitive annual data will come later next year.

We also note that this data does include forest loss caused by natural forces and burned areas.

Our geographic range for the Amazon is a hybrid between both the biogeographic boundary (as defined by RAISG) and watershed  boundary, designed for maximum inclusion.

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 #137: New Illegal Gold Mining Hotspot in Peruvian Amazon – Pariamanu

Posted on by dcadmin
Image 1. Very high-resolution image of the recent gold mining deforestation (10 hectares) in the new hotspot around the Pariamanu river. Data: Planet (Skysat)

In 2019, the Peruvian government launched Operation Mercury to confront the illegal gold mining crisis in the southern Amazonian area known as La Pampa (Madre de Dios region).

As a result, deforestation decreased 90% in this critical area (MAAP# 130).

Some illegal gold mining, however, has moved to several new hotspots (Image 1), although at much lower levels.

The most emblematic hotspot is located along the Pariamanu River, northeast of La Pampa in the Madre de Dios region (see Base Map, below).

We have documented the gold mining deforestation of 204 hectares (504 acres) in the Pariamanu area from 2017 to the present

This mining activity is clearly illegal because it is located within Brazil-nut forestry concessions, and is outside the permitted mining zone (commonly called the “mining corridor”).

Fortunately, a series of timely actions by the Peruvian Government has minimized the irreversible damage along the Pariamanu (see below).

The objective of this report is to present Pariamanu as an emblematic case that links technology with the rapid response action of public entities to address illegal activity in the Amazon.

It also represents a concrete case of strategic collaboration between civil society and the government to try and achieve zero illegal deforestation (and avoided deforestation).

Pariamanu

Base Map

The Base Map shows the location of illegal gold mining along the Pariamanu River, in the southern Peruvian Amazon (Madre de Dios region).

For context, La Pampa (the previous epicenter of illegal mining) and the regional capitol city of Puerto Maldonado are inlcuded. We also show another new illegal mining hotspot next to La Pampa, known as Apaylon.

In total, we have documented the deforestation of 204 hectares (504 acres) of primary forest caused by illegal gold mining in Pariamanu since 2017, indicated in red.

Note that this deforestation is located within Brazil nut forestry concessions and outside the “mining corridor,” thus clearly indicating its illegality.

Satellite Video: Illegal Gold Mining Deforestation in Pariamanu

We present a satellite image video showing an example of illegal gold mining in the Pariamanu area. These images show the deforestation of 71 hectares (175 acres) between 2016 (first image) and 2021 (last image), in the area indicated by the white inset box in the Base Map above. Note that each image is from July of each year (2016-20), with the exception of 2021 which shows January and March. Press the “play” button (lower left) to start the video.

MAAP Reports & Government Action

Operativo en Pariamanu, septiembre del 2020. Foto: FEMA Madre de Dios.

The first MAAP report about Pariamanu was published in November 2016, where we described “the start of mining in a new area” (MAAP #50). We found the mining-caused deforestation of 69 hectares (170 acres) on the banks of the Pariamanu river.

In January 2020, we published the second MAAP report about Pariamanu, documenting that the mining deforestation increased to 99 hectares (245 acres) (MAAP # 115). In this report, we warned that there were indications that some miners displaced by Operation Mercury (in February 2019) have moved to this area.

In response to this situation, the Peruvian Government, led by the Special Prosecutor for Environmental Matters (known as FEMA), carried out a series of field operations in 2020 (May, August and September, respectively), as an extension of Operation Mercury focused on cracking down on the illegal mining in Pariamanu.

The operations were effective in destroying mining equipment and sending a strong message that the government was engaged in this area.

However, we found that gold mining deforestation continued in several small areas between October 2020 and March 2021 (see Image 2), reaching the new total of 204 hectares (504 acres).

Fortunately, the government continues to respond effectively. Most recently (March 19, 2021), FEMA and the Peruvian Coast Guard carried out a new operation in Pariamanu, finding an illegal mining camp and equipment.

As mentioned above, the objective of this section (and this report) is to present Pariamanu as an emblematic case that links technology with the rapid response action of public entities to address illegal activity in the Amazon. It also represents a concrete case of strategic collaboration between civil society and the government to try and achieve zero illegal deforestation (and avoided deforestation).

MAAP #138: As Brazil negotiates with world, Amazon deforestation continues in 2021

Posted on by dcadmin

Expanding new 2021 deforestation in the Brazilian Amazon (Mato Grosso). Data: Planet. Click to enlarge image.

Brazil is currently in high-profile negotiations with countries such as the United States and Norway for international compensation in exchange for improved action to address Amazon deforestation.*

While this may be a positive development diplomatically, on the ground extensive deforestation continues.

We recently reported that, in 2020, Brazil had the sixth-highest primary forest loss on record (1.5 million hectares) and a 13% increase from 2019 (MAAP #136).

Here we present a first look at 2021 Brazilian Amazon deforestation.

This early analysis is important because a) it provides real-time context for the negotiations, and b) these are the first areas that are likely to be burned in the upcoming fire season (see MAAP #129).

We first analyzed a new generation of early warning forest loss alerts, based on 10-meter resolution imagery (a major upgrade from the previous 30-meter alerts).* These alerts indicate the loss of over 175,000 hectares of primary forest thus far in 2021.

We then investigated the most urgent (large alert clusters) with even higher resolution (3 meters) satellite imagery from Planet.

Below, we present a series of high-resolution imagery videos showing key examples of 2021 Brazilian Amazon deforestation.

Primary forest hotspots 2021 (thru April 4). Data: UMD/GLAD, MAAP.

Forest Loss Alerts

The alerts indicate the loss of 175,330 hectares of primary forest in the Brazilian Amazon between January 1 and April 4, 2021.

The Base Map illustrates where this deforestation has been concentrated.

Note the heavy concentrations in the states of Mato Grosso, Pará, and Amazonas, followed by Rondônia and Roraima.

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%.

Base Map. Forest loss hotspots across the Amazon in 2020. Data: UMD/GLAD, RAISG, MAAP. The letters A-G correspond to the zoom examples below.

We present a first look at the major hotspots of primary forest loss across the Amazon in 2020 (see Base Map).*

There are several major headlines:

  • We estimate over 2 million hectares (5 million acres) of primary forest loss across the nine countries of the Amazon in 2020.*
    p
  • The countries with the highest 2020 primary forest loss are 1) Brazil, 2) Bolivia, 3) Peru, 4) Colombia, 5) Venezuela, and 6) Ecuador.
    p
  • The majority of the hotspots occurred in the Brazilian Amazon, where massive deforestation stretched across nearly the entire southern region. Many of these areas were cleared in the first half of the year and then burned in July and August. In September, there was a shift to actual forest fires (see MAAP #129).
    p
  • Several of the most intense hotspots were in the Bolivian Amazon, where fires raged through the dry forests (known as the Chiquitano) in the southeast region.
    p
  • There continues to be an arc of deforestation in the northwestern Colombian Amazon, impacting numerous protected areas.
    p
  • In the Peruvian Amazon, deforestation continues to impact 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).

Below, we show a striking series of high-resolution satellite images that illustrate some of the major deforestation events across the Amazon in 2020 (indicated A-G on the Base Map).

Widespread Deforestation in the Brazilian Amazon

Zooms A-C show examples of a troublingly common phenomenon in the Brazilian Amazon: large-scale deforestation events in the first half of the year that are later burned in July and August, causing major fires due to the abundant recently-cut biomass. Much of the deforestation in these areas appears to associated with clearing rainforests for cattle pastures. The three examples below show the striking loss of over 21,000 hectares of primary forest in 2020.

Zoom C. Deforestation in Brazilian Amazon (Para state) of 15,250 hectares between January (left panel) and October (right panel) 2020. Data: Planet.

Forest Fires in the Brazilian Amazon

In September, there was a shift to actual forest fires in the Brazilian Amazon (see MAAP #129). Zoom D and E show examples of these major forest fires, which burned over 50,000 hectares in the states of Pará and Mato Grosso. Note both fires impacted indigenous territories (Kayapo and Xingu, respectively).

Arc of Deforestation in the Colombian Amazon

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, Zoom G 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.

Deforestation in the central Peruvian Amazon

Finally, Zoom H 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.

*Notes and Methodology

The analysis was based on early warning forest loss alerts known as GLAD alerts (30-meter resolution) produced by the University of Maryland and also presented by Global Forest Watch. It is critical to highlight that this data represents a preliminary estimate and more definitive data will come later in the year. For example, our estimate does include some forest loss caused by natural forces. Note that this data detects and classifies burned areas as forest loss. Our estimate includes both confirmed (1,355,671 million hectares) and unconfirmed (751,533 ha) alerts.

Our geographic range is the biogeographic boundary of the Amazon as defined by RAISG (see Base Map above). This range includes nine countries.

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).

We have entered the peak deforestation season in the Peruvian Amazon, so it is also a critical time for real-time monitoring (MAAP’s specialty).

Here, we highlight the major deforestation events documented so far in 2020 (through August 23).

The Base Map shows the current forest loss hotspots, indicated by the colors yellow, orange and red.

Below, we present the most urgent deforestation cases, caused by gold mining and agriculture (both large and small scale), the current leading deforestation drivers in Peru.

The Letters A-I on the Base Map correspond to the location of the cases described below.

One of the key cases is the new illegal gold mining hotspot along the Pariamanu river (Letter A in the southern Peruvian Amazon).

Another important case is the expanding large-scale agriculture by a Mennonite colony that continues causing an alarming deforestation.

The other cases deal with small-scale agriculture, which cumulatively represent the main deforestation driver in Peru.

Urgent Deforestation Cases 2020

1. Gold Mining

In MAAP #121, we reported that, in general, gold mining deforestation has decreased in the southern Peruvian Amazon following the government’s Operation Mercury, but it does continue in several critical areas. The images below show two of these areas (Pariamanu and Araza) with alarming new deforestation in 2020.

A. Pariamanu

The following image shows the gold mining deforestation of 52 acres (21 hectares) of primary forest along the Pariamanu River in the southern Peruvian Amazon (Madre de Dios region) between January (left panel) and August (right panel) of 2020. We highlight that the Peruvian government has just carried out an operation against the illegal mining activity in this area.

B. Araza

The following image shows the gold mining deforestation of 114 acres (46 hectares) along the Chaspa River in the Puno region, between January (left panel) and August (right panel) of 2020.

2. Large-scale Agriculture

C. Mennonite Colony (near Tierra Blanca)

We reported last year that a new colony of Mennonites caused the deforestation of 4,200 acres (1,700 hectares) between 2017 and 2019 in the Loreto region (MAAP #112). The following image shows the additional deforestation of 820 acres (332 hectares) in 2020 between January (left panel) and August (right panel).

3. Small-scale Agriculture

D. Jeberos

In 2018, we reported on the construction of a new road (65 km) cutting through primary forest in the Loreto region, between the city of Yurimaguas and the town of Jeberos (MAAP #84). The following image shows the deforestation of 40 acres (16 hectares) along the new road in 2020, between January (left panel) and August (right panel).

Metodology

The analysis was based on early warning GLAD alerts from the Universidad de Maryland and Global Forest Watch.

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%.
