As part of USAID’s Prevent Project (dedicated to combating environmental crimes in the Amazon), we conducted an updated analysis of illegal gold mining deforestation in the southern Peruvian Amazon.

In early 2019, the Peruvian government launched Operation Mercury, an unprecedented crackdown on the rampant illegal gold mining in the region.

The Operation initially targeted an area known as La Pampa, the epicenter of the illegal mining. In 2020, it expanded to surrounding critical areas.

In this report, we compare rates of gold mining deforestation before vs after Operation Mercury at six key sites (see Base Map and Methodology below).

We report four major results:

1) Gold mining deforestation decreased 90% in La Pampa (the most critical mining area) following Operation Mercury.

2) Gold mining deforestation increased in three key areas –Apaylon, Pariamanu, and Chaspa – indicating that some miners expelled from La Pampa moved to surrounding areas. The Peruvian government, however, has recently carried out major interventions in all three of these areas.

3) Overall, gold mining deforestation decreased 78% across all six sites following Operation Mercury.

4) Illegal mining does persist, however. We documented 1,115 hectares of gold mining deforestation across all six sites since Operation Mercury (but, compared to 6,490 hectares before the Operation).

Below, we provide a more detailed breakdown of the major results across all six sites. We also present a series of very high resolution satellite images (Skysat) of the recent gold mining deforestation.

Base Map – 6 Major Illegal Gold Mining Sites

The Base Map illustrates the results across the six major gold mining fronts in the southern Peruvian Amazon. Red indicates gold mining deforestation post Operation Mercury (March 2019 – October 2020), while yellow indicates the pre Operation baseline (January 2017 – February 2019).

In La Pampa, we documented the dramatic loss of 4,450 hectares within the buffer zone of Tambopata National Reserve (Madre de Dios region) prior to Operation Mercury. Following the Operation, we confirmed the loss of 300 hectares. Note the main mining front in the core of the buffer zone has essentially been stopped, with most recent activity further north near the Interoceanic Highway.

In neighboring Alto Malinowski, located in the buffer zone of Bahuaja Sonene National Park (Madre de Dios region), we documented the loss of 1,558 hectares prior to Operation Mercury. Following the Operation, we confirmed the loss of 419 hectares.

In Camanti, located in the buffer zone of Amarakaeri Commuanl Reserve, we documented the loss of 336 hectares prior to Operation Mercury. Following the Operation, we confirmed the loss of 105 hectares.

In Pariamanu, located in the primary forests along the Pariamanu River (Madre de Dios region), we documented the loss of 72 hectares prior to Operation Mercury. Following the Operation, we confirmed the loss of 98 hectares. In response, the government conducted a major intervention in August 2020.

In Apaylon, located in the buffer zone Tambopata National Reserve (Madre de Dios region), we documented the loss of 73 hectares prior to Operation Mercury. Following the Operation, we confirmed the loss of 78 hectares. In response, the government has conducted a series of interventions in the area during 2020.

Chaspa, located in the buffer zone of Bahuaja Sonene National Park (Puno region), represents a unique case of a new gold mining front that appeared following Operation Mercury. Starting in September 2019, we documented the deforestation of 113 hectares impacting the Chaspa River watershed. In response, the government conducted a major intervention in October 2020.

Gold Mining Deforestation Trends

The following chart illustrates that gold mining deforestation fronts decreased following Operation Mercury in the three largest fronts (La Pampa, Alto Malinowski, and Camanti), and increased in three smaller areas (Pariamanu, Apaylon, and Chaspa). Thus, overall gold mining deforestation decreased 78% across all six major sites following Operation Mercury.

Table 1. Rates of gold mining deforestation before (orange) and after (red) Operation Mercury. Data: MAAP.

In La Pampa, the gold mining deforestation averaged 165 hectares per month prior to Operation Mercury. Following the Operation, the deforestation dropped to 17 hectares per month, an overall 90% decrease.

In Alto Malinowski, the gold mining deforestation dropped from 58 hectares per month to 23 hectares per month following Operation Mercury, an overall 60% decrease.

In Camanti, the gold mining deforestation dropped from 12.5 hectares per month to 6 hectares per month following Operation Mercury, an overall 54% decrease.

In Pariamanu, the gold mining deforestation increased from 2.8 hectares per month to 5 hectares per month following Operation Mercury, an overall 87% increase.

In Apaylon, the gold mining deforestation increased from 2.8 hectares per month to 4 hectares per month following Operation Mercury, an overall 43% increase.

Chaspa, located in the buffer zone of Bahuaja Sonene National Park, represents the unique case of a new gold mining front that appeared following Operation Mercury (8.5 hectares per month).

Very High Resolution Satellite Imagery (Skysat)

We recently tasked very high resolution satellite imagery (Skysat, 0.5 meter) for the major illegal gold mining areas. Below, we present a series showing some of the highlights from these images. Note that insets (in the upper corner of each image) show the same area before the mining activity (see red points as a reference).

Methodology

We analyzed high-resolution imagery (3 meters) from the satellite company Planet obtained from their interface Planet Explorer. Based on this imagery, we digitized gold mining deforestation across six major sites: La Pampa, Alto Malinowski, Camanti, Pariamanu, Apaylon, and Chaspa. These were identified as the major active illegal gold mining deforestation fronts based on analysis of automated forest loss alerts generated by University of Maryland (GLAD alerts) and the Peruvian government (Geobosques) and additional land use layers. The area referred to as the “mining corridor” is not included in the analysis because the issue of legality is more complex.

Across these six sites, we identified, digitized, and analyzed all visible gold mining deforestation between January 2017 and the present (October 2020). We defined before Operation Mercury as data from January 2017 to February 2019, and after Operation Mercury as data from March 2019 to the present. Given that the former was 26 months and the latter 20 months, during the analysis the data was standardized as gold mining deforestation per month.

The data is updated through October 2020.

Thanks to the support of the USAID, via the Prevent Project, dedicated to the prevention and combat of environmental crimes in the Amazon, we conducted a detailed analysis of recent illegal gold mining deforestation in the southern Peruvian Amazon.

The objective is to understand the trends from early 2017 to June 2020 (which includes the first part of the mandatory quarantine issued by the Peruvian government as of March 16, 2020 due to the coronavirus pandemic).

We focus on the buffer zones of two protected areas in the Madre de Dios region: Tambopata National Reserve and Bahuaja Sonene National Park (see Base Map).*

This area includes La Pampa, the current highest intensity illegal mining zone in the country. In February 2019, the Peruvian government launched Operation Mercury  to confront the illegality in La Pampa and surrounding areas.

The Base Map shows that gold mining deforestation in La Pampa decreased over 90% following Operation Mercury.

However, illegal gold mining does continue after Operation Mercury (including during the coronavirus state of emergency), but at lower rates. Thus, current snapshots may be misleading and recent context is important.

On the Base Map, the red arrows indicate the areas with the most recent illegal activity (click the image to enlarge). See below for more details.

Main Results

Table 1. Illegal gold mining deforestation before (yellow) and after (red) Operation Mercury in the buffer zones of Madre de Dios. Data: MAAP.

The Base Map and Table 1 illustrate the following key results:

• In La Pampa, we documented mining deforestation of 173 hectares (428 acres) per month before Operation Mercury (January 2018 – February 2019). After the intervention, deforestation was reduced to 14 hectares (36 acres) per month (March 2019 – May 2020), a decrease of 92%.
  .
• Upstream, in the Alto Malinowski, we documented the mining deforestation of 61 hectares (150 acres) per month before Operation Mercury. After the intervention, deforestation was reduced to 28 hectares (69 acres) per month, a decrease of 53%.
  .
• Downstream, in the Apaylon area, we documented the mining deforestation of 2.9 hectares (7 acres) per month, before Operation Mercury. After the intervention, deforestation increased to 4 hectares (10 acres) per month, an increase of 41%. Apaylon is main area in the buffer zone where deforestation has increased.
  .
• Within Tambopata National Reserve, we documented the mining deforestation of 6.5 hectares (16 acres) per month, before Operation Mercury. After the intervention, deforestation was reduced to 0.5 hectares (1.2 acres) per month, a decrease of 93%.
  .
• Overall, illegal gold mining does continue in the buffer zones of Madre de Dios, but at lower rates than the previous two years. We documented the gold mining deforestation of 797 hectares (1,670 acres) after Operation Mercury.
  .
• Regarding the speculation that illegal activity would increase during the coronavirus pandemic, we have not documented any major increase or surge in the buffer zones of Madre de Dios.* Illegal mining does continue, however, we documented the deforestation of 80 hectares (198 acres) during the quarantine.

Displaced Miners?

Table 2. Deforestation by illegal gold mining before (yellow) and after (red) Operation Mercury in two other threatened areas. Data: MAAP.

There has also been speculation that the focus of Operation Mercury in La Pampa would lead to illegal miners moving to other areas.* Base Map 2 shows two of the most threatened areas: Camanti and Pariamanu.

These are the main results for these two areas:

• In Camanti (located in the buffer zone of Amarakaeri Communal Reserve), we documented the gold mining deforestation of 13.3 hectares (33 acres) per month before Operation Mercury. After the intervention, deforestation was reduced to 6.1 hectares (15 acres) per month, a decrease of 54%.
  .
• In Pariamanu, we documented  the mining deforestation of 2.5 hectares (6 acres) per month before Operation Mercury. After the intervention, it increased to 4.2 hectares (10 acres) per month, an increase of 70%.
  .
• In summary, illegal gold mining continues in these two areas outside La Pampa. We documented the mining deforestation of 175 hectares (432 acres) after Operation Mercury (including 22 hectares during the pandemic). There is some evidence that miners are being displaced to Pariamanu, but there has not been a surge in Camanti.

Statement of the Peruvian Protected Area Agency (SERNANP)

El Servicio Nacional de Áreas Naturales Protegidas por el Estado (SERNANP) nos ha comunicado lo siguiente:

• La actividad de control y vigilancia en la Reserva Nacional Tambopata es permanente y las autoridades (SERNANP, Policía Nacional del Perú, Fiscalías Especializadas en Materia Ambiental, y Marina de Guerra del Perú) continúan interviniendo a todas las actividades de minería ilegal, manteniendo el 100%.

• Las zonas de amortiguamiento son espacios que están sujetos a la intervención de las autoridades de la Operación Mercurio (no del SERNANP). Se han realizado intervenciones continuas e interdicciones tanto en  las zonas indicadas en el reporte, como en Apaylon y Camanti.
  ,
• Cabe mencionar que la Operación Mercurio, durante el 2019 y sobre todo en el 2020 (Incluyendo el período de cuarentena) ha ampliado sus operativos mas allá de la Pampa, lo cual explica porque en Camanti las cifras también se ha reducido.  En el segundo semestre de 2020 y en el 2021, se espera que los operativos es amplíen a otras zonas de Madre de Dios.

*Notes

• The area referred to as the “mining corridor” (see Base Map) is not included in the analysis.
  .
• Mining deforestation rates (hectares per month) during the coronavirus pandemic state of emergency (starting mid-March): La Pampa 16.3, Alto Malinowski 11.7, Apaylon 3.5, Tambopata National Reserve 0.4, Camanti 3.8, Pariamanu 4.7.
  .
• Speculation in the media:
  Mineros de La Pampa amenazan la Reserva Comunal Amarakaeri
  Incremento de minería ilegal durante la cuarentena
