MAAP #196: Mining Impacts Calculator: Analysis in 3 Indigenous Communities of the Southern Peruvian Amazon

Website of the Gold Mining Impact Calculator developed by CSF.

Illegal gold mining has generated massive deforestation in the southern Peruvian Amazon (MAAP #208). This activity also affects several of the main rivers (such as the Madre de Dios, Inambari, Tambopata, Malinowski and Colorado), and also their tributaries and secondary bodies of water. All of them are contaminated by excess sediment and the presence of toxic substances such as mercury and arsenic, which are dumped during the mineral extraction process.

Thus, illegal mining activity generates large economic losses due to the direct impact on ecosystem services and other more sustainable economic activities.

Quantifying these impacts in monetary terms has been a challenge for national authorities lacking adequate instruments capable of establishing economic values of the impact generated by illegal mining activity in the Amazon. In this context, in 2021 the Mining Impacts Calculator was presented, a digital economic valuation tool developed by the organization Conservation Strategy Fund (CSF). This tool allows users to calculate the social and environmental impact of illegal gold mining in the Amazon1, in order to improve decision-making, and establish changes and/or improvements in the regulatory framework around this activity.

This report shows the results of the application of the Calculator in recent (2022 and 2023) illegal mining areas within 3 native communities, all located in the buffer zone of the Amarakaeri Communal Reserve in southern Peru. This is an effort to show from a comprehensive perspective (economic and environmental) the implications of deforestation due to illegal mining in the Peruvian Amazon.

The economic calculations of the socio-environmental impacts were carried out using the Gold Mining Impact Calculator. The results show that from the beginning of 2022 to August 2023, there was a total economic loss amounting to 593 million dollars ($593,786,943) for the socio-environmental impacts, generated by deforestation, sedimentation and contamination of rivers by mercury in three indigenous communities of Madre de Dios. The details about the data that was entered into this tool to obtain the results mentioned in the report are explained in the methodology section.

Base Map

The Base Map shows the location of the case studies of this report, which is focused on quantifying the impact of illegal mining, through economic valuation, in 3 native communities in the buffer zone of the Amarakaeri Communal Reserve: San José de Karene, Puerto Luz, and Barranco Chico, all located in the province of Manu, department of Madre de Dios. Additionally, on the map, you can see historical, recent, and current deforestation.

Impact in the San José de Karene Native Community

The native community of San José de Karene has lost 914 hectares from 2022 to August 2023 (See Map 2). In 2022, they lost 312 hectares and so far in 2023, until the month of August, 602 new hectares have been lost. It should be noted that the community currently has mining rights that overlap with its communal territory. When applying the Gold Mining Impact Calculator, it can be seen that the total socio-environmental impacts for 2022 were 86 million dollars ($86,258,492). On the other hand, so far in 2023, this figure increased significantly, reaching 166 million dollars ($166,657,897), as can be seen in Figure 1.

Impact in the Puerto Luz Native Community

The native community of Puerto Luz has lost 270.6 hectares between 2022 and August 2023 (See Map 3). In 2022, they lost 100 hectares and so far from 2023 until the month of August they have lost 170.6 new hectares. The community currently has mining rights that overlap with its communal territory. Applying the tool, it is estimated that the total socio-environmental impacts for 2022 were 24 million dollars ($24,947,385), while so far in 2023 it was 44 million dollars ($44,205,548).

MAAP #208: Gold mining in the southern Peruvian Amazon, summary 2021-2024

Figure 1. Recent expansion of illegal gold mining in the southern Peruvian Amazon. Data: Planet, NICFI

With the technical support of USAID (United States Agency for International Development) and Norad (Norwegian Agency for Development Cooperation),1 we have published a series of reports on the dynamic situation regarding gold mining in the southern Peruvian Amazon during recent years 2.

Illegal gold mining reached crisis levels between 2017 and 2018 in the area known as La Pampa (Madre de Dios region), eliminating thousands of hectares of primary forest in the buffer zone of the Tambopata National Reserve.

In early 2019, the Peruvian government implemented Operation Mercury, a multi-sectoral intervention against illegal mining, initially focusing on La Pampa. This operation was later replaced (in 2021) by the Restoration Plan, which included interventions in other critical mining areas of the Madre de Dios region in the southern Peruvian Amazon.

In this report, we offer a concise summary of the mining situation during the past three years (between January 2021 and March 2024) in the southern Peruvian Amazon, in the context of the Restoration Plan.

During this period, we recorded a total mining deforestation of 30,846 hectares (76,222 acres), equivalent to over 40,000 soccer fields.8

Of this total, three-quarters (74%) of the deforestation occurred within the official Mining Corridor, a large area (almost half a million hectares) where the government permits artisanal and small-scale mining to organize and promote this activity3. In other words, the vast majority of mining deforestation is not necessarily illegal, because it is in the corridor designated for this activity.

The remaining one-quarter (26%) of the deforestation corresponds to probable illegal mining. That is, mining activities carried out in prohibited areas outside the Mining Corridor, such as protected areas, their buffer zones, territories of Native Communities, and bodies of water.4

Base Map: Mining deforestation in the southern Peruvian Amazon

We highlight several important findings illustrated in the Base Map and Table 1, both presented below. In both cases, we highlight recent mining deforestation (between January 2021 and March 2024). Red indicates deforested areas outside of the Mining Corridor (representing our estimate of illegal mining), while yellow indicates recently deforested areas within the Mining Corridor.

Base Map. Mining deforestation inside and outside the Madre de Dios Mining Corridor, in the southern Peruvian Amazon, between January 2021 and March 2024. Data: ACCA/MAAP.

We found that mining deforestation is concentrated within the Mining Corridor, representing 73.8% of the total (22,756 hectares). This is especially evident in the Guacamayo mining area and along the Madre Dios River.

The rest of the mining deforestation (26.2%) is outside the Mining Corridor. The majority of this deforestation (14.6%) is occurring in the 10 Native Communities of the area, covering a total of 4,494 hectares. The most affected communities are San José de Karene (1,099 ha), Barranco Chico (1,008 ha) and Tres Islas (827 ha), followed by Puerto Luz (305 ha), Boca Inambari (305 ha), Kotsimba (297 ha), San Jacinto (269 ha), Shiringayoc (267 ha), Arazaire (78 ha) and El Pilar (40 ha). However, there are different trends. For example, mining deforestation between 2021 and 2024 has decreased in Barranco Chico, while it has increased in San José de Karene, Tres Islas and Boca Inambari.

We also identified mining deforestation of 2,439 hectares (7.9%) in buffer zones of Protected Areas. The most affected are Tambopata National Reserve (such as the Mangote area, see Figure 1), Bahuaja Sonene National Park, and Amarakaeri Communal Reserve. However, it must be emphasized that mining within the actual Protected Areas has been effectively controlled by the Peruvian government, through the National Service of Protected Natural Areas (SERNANP).

In addition, we detected some mining deforestation (198 hectares) in Brazil nut forestry concessions located in the Pariamanu area.

Finally, it is important to mention that in the critical area known as La Pampa (noted above), the expansion of mining deforestation has been effectively stopped after Operation Mercury. A recent report (MAAP #193), however, showed a large increase in mining activity in previously deforested areas of La Pampa.

Monitoring & Control of Native Communities by FENAMAD

As noted above, a large portion of the illegal mining deforestation in the southern Peruvian Amazon is occurring within the territory of the Native Communities. These Native Communities are part of an articulated federation known as FENAMAD, which is the regional representative organization of the indigenous peoples of the Madre de Dios River basin. FENAMAD defends the fundamental and collective rights of indigenous peoples and native communities, including indigenous peoples in situations of isolation and initial contact.

1. First, FENAMAD identifies priority communities threatened by illegal mining and requiring urgent monitoring.

2. Subsequently, Amazon Conservation leads real-time satellite monitoring in these prioritized communities and delivers confidential reports to FENAMAD.

3. FENAMAD then reviews the reports together with the territory monitors and the results are shared with the affected native communities who decide whether these cases require a legal process.

4. FENAMAD formulates the Environmental Legal Complaint files and delivers them to the corresponding government institutions (Prosecutor’s Office Specialized in Environmental Matters of Madre de Dios –FEMA, National Police of Peru –PNP, Ecological Police of Peru, among others).

5. Finally, in selected cases, the government organizes and directs an on-the-ground operation against illegal mining activity and associated equipment.

This process has led to the execution of 5 government-led operations between 2022 and 2024, in three communities: Barranco Chico, Kotsimba and San José de Karene (see Base Map).

Of these operations, 3 took place in the community of Barranco Chico,5 which has been especially affected by illegal mining deforestation (967 hectares in the last three years). Figure 2 indicates the location of these operations. It should be noted that mining deforestation in Barranco Chico has decreased between 2021 and 2024, likely due to these types of interventions.

Figure 2. Location of operations against illegal mining in the Barranco Chico Native Community.

The other operations occurred in the communities of Kotsimba6 and San José de Karene7.

It is worth noting that this collaboration between FENAMAD and Amazon Conservation, which is supported by the Norwegian Agency for Development Cooperation (NORAD), is currently expanding to additional native communities within the impacted region.

3 The Mining Corridor, named by Legislative Decree No. 1100, as the “Zone of small mining and artisanal mining in the department of Madre Dios”, catalogs mining activities as:

– Formal: It is carried out with authorization for exploration and exploitation in a specific area, with conditions and operations regulated by the legal framework of the mining sector. It has approved environmental, administrative and operational permits.

– Informal: Artisanal and small-scale mining operates in permitted areas for mineral extraction and uses permitted machinery. Although it does not have authorization to carry out mining activity, it is in the formalization process in accordance with the provisions of Legislative Decree No. 1105, which establishes provisions for the formalization process of small-scale mining and artisanal mining activities. Therefore, it is considered an administrative infraction, but not a crime.

– Illegal: Exploration, extraction and exploitation of mineral resources in prohibited areas (such as Protected Areas and bodies of water) and using prohibited machinery, failing to comply with administrative, technical and environmental requirements established in Peruvian legislation. This is a crime stipulated in article 207-A of the Penal Code, which carries a custodial sentence.

4 Although keep in mind that there may be mining concessions within the Native Community territories.

5 FEMA operations in the Barranco Chico community occurred in April 2022 (América Televisión video), April 2023 (El Comercio) and June 2023. There was an initial operation before the project in 2021.

6 FEMA operation in the Kotsimba community occurred in October 2023.

7 FEMA operation in the community of San José de Karene occurred in April 2024.

8 Of this total (30,846 hectares), 28,292 hectares occurred during 2021-2023, while 2,554 hectares occurred in the first quarter of 2024.

9 Undesignated refers to areas without a formal designation and not included in any of the other categories.

Methodology

We used LandTrendR, a temporal segmentation algorithm that identifies changes in pixel values over time, to detect forest loss within the mining corridor between January 2021 and March 2024 using the Google Earth Engine platform. Importantly, this method was originally designed for moderate resolution Landsat imagery (30 meters)1, but we adapted it for higher spatial resolution (4.7 meters) NICFI-Planet monthly mosaics.2

In addition, we created a baseline for the period 2016 – 2020 to eliminate previously deforested areas (pre 2021), to account for rapid changes in the natural revegetation process.

Finally, we manually separated forest loss from mining vs other causes, to report specifically on direct mining-related impacts between 2021 and 2024. We used several resources to help this manual process, such as alerts with radar images (RAMI) from the SERVIR Amazonía program, historical data from the Amazon Scientific Innovation Center – CINCIA (from 1985 to 2021), and forest loss data from the Peruvian state (National Forest Conservation Program for Climate Change Mitigation) and the University of Maryland.
