MAAP #182: Gold Mining Deforestation in the Ecuadorian Amazon

Posted on by dcadmin
Base Map. Major cases of recent gold mining deforestation in Ecuadorian Amazon.

Gold mining is one of the major deforestation drivers across the Amazon, with well-known cases in Peru, Brazil, and Venezuela.

In a recent series of technical articles*, in collaboration with the Ecuadorian organization Foundation EcoCiencia, we have also shown that gold mining is escalating in the Ecuadorian Amazon.

Here, we summarize the results from the series and present 5 major cases of recent gold mining deforestation in Ecuador (see Base Map).

These cases, which include gold mining expansion in protected areas, indigenous territories, and primary forests, are:

  • Punino River, located between Napo and Orellana provinces, has experienced the rapid mining deforestation expansion of 217 hectares since 2019.
    l
  • Yutzupino, located in Napo province, has experienced mining deforestation of 125 hectares since 2021. Surrounding sites in Napo have added 490 hectares since 2017.
    l
  • Shuar Arutam Indigenous Territory, located in Morona Santiago province, has experienced 257 hectares of mining deforestation since 2021.
    l
  • Podocarpus National Park, located in Zamora Chinchipe province, has experienced 25 hectares of mining deforestation within the park since 2019.
    k
  • Upper Nangaritza River Protected Forest, also located in Zamora Chinchipe has experienced 545 hectares of mining deforestation since 2018.

In total, we have documented the recent gold mining deforestation of 1,660 hectares (4,102 acres) in the Ecuadorian Amazon. This is equivalent to 2,325 soccer fields.

For each case, we show high-resolution satellite images of the recent gold mining deforestation.

Case Studies – Recent Gold Mining Deforestation in the Ecuadorian Amazon

For each of the five cases presented below, we show both a high-resolution (3 meters) example of the recent mining deforestation (left panel) and very-high resolution (0.5 meters) zoom of the mining activity (right panel).

Punino River

Along the Punino River, located between Napo and Orellana provinces, we have documented the rapid mining deforestation expansion of 217 hectares since November 2019. Alarmingly, much of this activity (85%) occurred most recently in 2022. See MAAP #176 for more details.

Case 1. Punino River.

Yutzupino/Napo

In this area, located in Napo province, we have documented the mining deforestation of 125 hectares since October 2021, including major impacts along the Jatunyacu River. Surrounding sites in Napo have added 490 hectares since 2017. See MAAP #151 and MAAP #162 for more details.

Case 2. Yutzupino/Napo.

Upper Nangaritza River Protected Forest

In Upper Nangaritza River Protected Forest, also located in Zamora Chinchipe province, we have documented the mining deforestation of 545 hectares since 2018 along the Nangaritza River. See MAAP #167 for more details.

Case 3. Upper Nangaritza River Protected Forest.

Shuar Arutam Indigenous Territory

In the Shuar Arutam Indigenous Territory, located in Morona Santiago province, we have documented the mining deforestation of 257 hectares since 2021. See MAAP #170 for more details.

Case 4. Shuar Arutam Indigenous Territory.

Podocarpus National Park

In Podocarpus National Park, located in Zamora Chinchipe province, we have documented the mining deforestation of 25 hectares since 2019 within the park, including the presence of over 200 mining camps. See MAAP #172 for more details.

MAAP #181: Illegal Gold Mining in Yanomami Indigenous Territory (Brazil)

Posted on by dcadmin
Base Map. Illegal mining deforestation alerts in Yanomami Indigenous Territory (northern Brazilian Amazon).

The Brazilian government recently launched a series of raids against illegal gold mining in Yanomami Indigenous Territory, located in the northern Brazilian Amazon (see inset of Base Map).

These raids highlight the severe consequences brought by illegal mining activity, particularly deforestation, contamination, malnutrition, and disease.

Here we present the results of a new machine learning algorithm that analyzes satellite imagery archives across large areas to quickly and precisely detect new gold mining deforestation fronts.

The resolution of these mining deforestation alerts is 10 meters, based on the European Space Agency’s freely available Sentinel-2 satellite imagery data.

These alerts reveal the extent of the gold mining deforestation in Yanomami Indigenous Territory is much greater than realized (see Base Map).

In the Base Map, the red dots indicate the most recent gold mining deforestation alerts, occurring in 2022.

Note that while the raids appear to be concentrated along the Uraricoera River, active gold mining deforestation is actually occurring all throughout the vast northern section of the territory, including the Parima and Mucajai Rivers as well.

We estimate the new gold mining deforestation of over 2,000 hectares since 2019. Much of this deforestation (67%, or 1,350 hectares) occurred most recently in 2022.

Below, we show five examples of this recent gold mining deforestation with high-resolution satellite imagery (3 meters) that confirm the alert detections.

Zooms of Illegal Gold Mining Deforestation, 2020 – 2022

Below, we show five examples of this recent gold mining deforestation with high-resolution (3 meter) satellite imagery that confirm the alert detections (see insets A-E in the Base Map). Note that two of the examples are on the the Uraricoera River, while the other three examples are from other parts of the territory.

Methodology

Gold mining deforestation alerts were generated by Amazon Mining Watch’s updated machine learning algorithim based on Sentinel-2 satellite imagery data.

The Amazon Mining Watch is a partnership between the Pulitzer Center´s Rainforest Investigations Network and Earthrise Media. These two nonprofit organizations have joined forces to bring together the power of machine learning and investigative journalism to shed light on large-scale environmental problems in the Amazon.

 

MAAP #180: Mennonites & Soy Deforestation in the Bolivian Amazon

Posted on by dcadmin
Base Map. Soy deforestation by Mennonite colonies in the Bolivian Amazon.

We continue with the second part in our series on soy deforestation in the Bolivian Amazon.

In the first part, see MAAP #179, we documented the massive soy-driven deforestation of 904,518 hectares (2.2 million acres) between 2001 and 2021 in the Bolivian Amazon.

During this time period, a large number of farming-based Mennonite colonies have been established in the southern Bolivian Amazon, helping drive the increase in soybean expansion in the region.1,2

Here, we incorporate colony location data to estimate the role of Mennonite colonies in this soy deforestation.

In summary, we find that Mennonites have caused a third (33%) of the soy deforestation in the Bolivian Amazon over the past 5 years (see Base Map).

Overall, Mennonites caused nearly a quarter (23%) of the total soy deforestation over the past 20 years (210,980 hectares, or 521,344 acres).

 

 

 

 

 

 

Mennonites & Soy Deforestation in the Bolivian Amazon

We estimate that Mennonite colonies have caused the deforestation of 210,980 hectares (521,344 acres) for soy expansion in the Bolivian Amazon between 2001 and 2021 (see Base Map). This accounts for 23% of the total soybean deforestation in Bolivia over the past 20 years.

This Mennonite-driven soy deforestation peaked in 2016 (31,728 hectares), following a previous peak in 2008 (see Graph 1). In general, note that Mennonite soy deforestation has been relatively high (>2,000 hectares) every year from 2001 to 2020.

Focusing on just the past five years (2017-21), Mennonites have cleared 33,234 hectares (82,123 acres). This represents an increase to 33% of the total soybean deforestation during this time period.

Satellite Images of Mennonite Colonies in the Bolivian Amazon

We present a series of recent satellite images showing examples of Mennonite colonies in the Bolivian Amazon. See the Base Map above for the location of the three zooms (A-C). Note that they are made up of highly-organized and connected agricultural plots that have been created following deforestation events over the past 20 years.

Methodology

For this series of reports, we employed a three-part methodology.

First, we mapped out “soy planted area” for 2001 to 2021 based on the data from Song et al 2021. This data is available on the University of Maryland’s GLAD site “Commodity Crop Mapping and Monitoring in South America.”3

Second, on top of the soy planted area noted above, we mapped out forest loss for 2001 to 2021, also based on data from the University of Maryland.4 This served as our estimate of soy-driven deforestation.

Third, on top of the soy planted area noted above, we incorporated an additional dataset from a recent study on the expansion of Mennonite colonies in Latin America.1 Spatial data from this study available here. We then estimated forest loss for these select Mennonite soy areas.

Base Map. Soy-driven deforestation in the Bolivian Amazon, 2001-2021. Click on map to enlarge.

It is generally known that commodities such as oil palm, soy, and cattle are major tropical deforestation drivers, but concise estimates are often difficult.

New satellite-based datasets are improving this situation. Notably, researchers recently published the first overview of soybean plantations for South America.1

Here, we use this data to estimate recent soy-driven deforestation in the Bolivian Amazon.

In the second part of this series, see MAAP #180, we incorporate additional data to estimate the role of Mennonite colonies in this soy deforestation.

In summary, we document the massive soy-driven deforestation of 904,518 hectares (2.2 million acres) between 2001 and 2021 in the Bolivian Amazon (see Base Map).

Of this total, Mennonites have caused 23% (210,980 hectares, or 521,344 acres).

 

 

 

 

 

Soy Deforestation in the Bolivian Amazon, 2001 – 2021

Soy has covered 2.1 million hectares of the southern Bolivian Amazon over the past 20 years, with current coverage around 1.2 million hectares.

We documented an extremely high level of soy-driven deforestation in the Bolivian Amazon: 904,518 hectares (2.2 million acres) between 2001 and 2021 (see Base Map above). This is a massive area, similar to the size of the U.S. state of Vermont.

This soy deforestation peaked in 2008 (92,000 hectares), but has been high (>18,000 hectares) every year between 2001 and 2019, meaning this is a long-running and persistent issue.

The vast majority of the total deforestation occurred in the Santa Cruz department, plus a small corner of adjacent Beni department.

Below, Figure 1 shows the overall massive soy deforestation over the past 20 years in the Bolivian Amazon, comparing 2001 (left panel) with 2021 (right panel).

Soy Deforestation in the Bolivian Amazon, 2017 – 2021

Of the total soy deforestation noted above, 11% (101,188 hectares, or 250,000 acres) occurred in just the past 5 years (2017-21).

Below, Figures 2-4 show examples of this recent soy deforestation, comparing 2017 (left panel) with 2021 (right panel). See the Base Map above for locations of insets A-C.
