Posted on by dcadmin
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%.

Gold mining continues to be one of the main causes of deforestation in the southern Peruvian Amazon, especially in the Madre de Dios region.

Here, we provide a comprehensive look at the most recent (2021-2022) gold mining-related deforestation in the area, combining two important types of data for the first time:

  1. Deforestation within the Mining Corridor, a large area delimited by the Peruvian government to organize and promote mining. Mining activity in this corridor, officially known as the “Small-scale and Artisanal Mining Zone in the department of Madre de Dios,” can be formal, informal, or illegal.1
    j
  2. Deforestation outside the Mining Corridor, which represents our estimate of illegal mining. According to current regulations (Legislative Decree No. 1336), illegal mining occurs in one or more territorial categories such as protected natural areas, indigenous reserves, and natural bodies of water (such as lakes or rivers). Therefore, for this report, the presence of mining-related deforestation in protected natural areas and their buffer zones, as well as indigenous communities, is considered an indicator of illegality. However, it is important to recognize the possibility that some of these findings may be covered by current regulations regarding mining formalization.2 Therefore, it is recommended to consider the findings of illegal deforestation as referential.

These two study areas cover a total of 1.38 million hectares and include all detected mining areas in the southern Peruvian Amazon.

We highlight several important findings (see Base Map and Table 1):

  • Table 1. Data: ACA/MAAP.

    We estimate a total deforestation of 18,421 hectares (45,520 acres) due to gold mining in the southern Peruvian Amazon in the last two years (2021-2022).
    l

  • Of this total, the majority of mining-related deforestation (76.6%, or 14,117 hectares) occurred within the Mining Corridor.
    l
  • The remaining deforestation (23.4%, or 4,304 hectares) took place outside the Mining Corridor. Breaking down this percentage, 15% is found in indigenous communities, 4.8% in buffer zones of protected natural areas, 0.8% in forest concessions, and 2.8% in non-zoned areas.
    j
  • Furthermore, we found that mining within protected natural areas, such as the Tambopata National Reserve and the Amarakaeri Communal Reserve, has been effectively controlled by the Peruvian government through the National Service of Protected Natural Areas (SERNANP).
    j
  • It is important to highlight that mining has stopped in the core of La Pampa (the most critical zone during the years 2014-2018) following Operation Mercury in early 2019 and the subsequent Restoration Plan in 2021.
    j
  • Compared to the years prior to Operation Mercury (2017-2018), there has been an approximate decrease of 4.5% (866 hectares) in mining-related deforestation. Most notably, there has been a major reduction in mining outside the corridor (from 47.7% to 23.4%), and a greater concentration within the corridor (from 52.3 to 76.6%).3  That is, an apparent major reduction in illegal mining.

Mining Corridor

Our main finding is that the vast majority (76.6%) of gold mining-related deforestation in the southern Peruvian Amazon occurred within the Mining Corridor.

We estimate that the deforestation due to mining is 14,117 hectares within the Mining Corridor in the last two years (2021-2022). Below, we present a series of zooms of some emblematic examples of recent mining-related deforestation in the corridor (Images A-C).

Image C: Mining Corridor

Outside of the Mining Corridor

The remaining deforestation due to mining (23.4%) is located outside the Mining Corridor. Breaking this down, 15% (2,769 hectares) occurred within indigenous territories, 4.8% (876 hectares) in buffer zones of protected areas, 0.8% (141 hectares) in forest concessions (for Brazil nuts), and 2.8% (517 hectares) in non-zoned areas during the last two years.

Regarding indigenous communities, the most affected were Barranco Chico (816 hectares) and San José de Karene (602 hectares), followed by Tres Islas (482 hectares), San Jacinto (177 hectares), Kotsimba (174 hectares), Puerto Luz (171 hectares), Boca Inambari (140 hectares), Shiringayoc (126 hectares), Arazaire (57 hectares), and El Pilar (23 hectares).

Regarding the buffer zones of protected areas, the most affected were the buffer zones of the Tambopata National Reserve, the Bahuaja Sonene National Park, and the Amarakaeri Communal Reserve. On the other hand, it has been found that mining within the actual protected areas, such as the Tambopata National Reserve and the Amarakaeri Communal Reserve, has been effectively controlled by the Peruvian government through the National Service of Natural Protected Areas (SERNANP).

Regarding forest concessions, deforestation due to mining was identified in 141 hectares within Brazil nut concessions in the Pariamanu and Pariamarca river basins.

Next, we continue with a series of zooms showing some emblematic examples of recent deforestation due to mining in the following prohibited areas: indigenous communities (Barranco Chico, Image D), buffer zone of the Bahuaja Sonene National Park (Chaspa, Image E), and Brazil nut concessions (Pariamanu, Image F).

We also present an important area in the buffer zone of the Tambopata National Reserve known as La Pampa (Image G). La Pampa was the epicenter of destructive deforestation due to gold mining between 2014 and 2018. We show that after Operation Mercury, which began in early 2019, the expansion of gold mining in La Pampa was essentially halted.

Notes

1The Mining Corridor, designated by Legislative Decree No. 1100 as the “Zone for small-scale and artisanal mining in the department of Madre de Dios,” categorizes mining activities as follows:

  • Formal: Completed formalization process with approved environmental and operational permits.
  • Informal: In the process of formalization; Operates only in authorized extraction areas, uses permitted machinery, and is considered an administrative offense, not a crime.
  • Illegal: Operates in prohibited areas such as bodies of water (e.g., rivers or lakes), uses prohibited machinery, is considered a criminal offense, and is punishable by imprisonment.

2 Due to the possibility that these activities could be existing operations prior to the declaration of Natural Protected Areas and their buffer zones.

3 The data for 2017-2018 were obtained from the Amazonian Scientific Innovation Center – CINCIA.

Methodology

Mining Corridor

We used LandTrendR, a temporal segmentation algorithm that identifies changes in pixel values over time, to detect forest loss within the Mining Corridor in 2021 and 2022 using the Google Earth Engine platform. It is important to note that this method was originally designed for Landsat images with moderate resolution (30 meters)1, but we adapted it for higher spatial resolution NICFI-Planet monthly mosaics (4.7 meters).2

Additionally, we created a baseline for the period 2016-2020 to eliminate old deforested areas (prior to 2021) due to rapid changes in the natural regrowth process.

Finally, we manually separated forest loss due to mining and other causes in 2021 and 2022 to specifically report on direct impacts related to mining. For this part of the analysis, we used various resources to aid the manual process, such as radar image alerts (RAMI) from the SERVIR Amazonia program, historical data from CINCIA from 1985 to 2020, forest loss data from the Peruvian government (National Forest Conservation Program for Climate Change Mitigation), and the University of Maryland.

  2.  Erik Lindquist, FAO, 2021

Outside the Mining Corridor

These places were identified as the main active fronts of deforestation due to gold mining, based on historical data from the Amazon Scientific Innovation Center – CINCIA and automatic alerts of forest loss generated by both the University of Maryland (GLAD alerts) and the Peruvian government platform (PNCBMCC-Geobosques).

The analysis combines the LandTrendr method (described earlier) with a photo interpretation based on high-resolution satellite images from Planet (3 meters). In each of the sites, we have detected, identified, and analyzed deforestation due to gold mining between 2021 and 2022. For areas with overlap between native communities and buffer zones, priority was given to the areas of the native communities.
