MAAP #60: Gold Mining Increases in Buffer Zone of Tambopata National Reserve

Posted on by dcadmin

In the previous MAAP #50, we presented an analysis of the extent of gold mining deforestation in the southern Peruvian Amazon as of September 2016. Here, we partially update the data for the area within the buffer zone of Tambopata National Reserve.* We document the increase of 1,135 acres (460 hectares) of illegal mining deforestation during the last 8 months, from September 2016 to May 2017 (see red in Image 60). That brings the total deforested area in the buffer zone to 10,970 acres (4,440 hectares) since 2012.

*The buffer zone does not form part of the respective protected area, thus it is not under the jurisdiction of the Peruvian national protected areas agency, SERNANP. However, the illegal activities that are being carried out in the buffer zone are putting the conservation values of the protected area at risk, and are under the jurisdiction of other entities in the Peruvian government.

High-Resolution Zooms

Image 60a shows the buffer zone’s most active deforestation front between September 2016 (left panel) and May 2017 (right panel). Inset A1 highlights the most recent deforestation, showing the advance just between March (left panel) and May (right panel) 2017. The red points (•) indicate the same place on both panels.

Movement of Illegal Mining Camps

Image 60b is a GIF that shows the continual movement of illegal mining camps towards the active deforestation front, between November 2015 and March 2017. Note that previous camps are abandoned after the relocation.

Legal Implications

Recently, a bill has been presented in the Peruvian Congress that proposes that illegal mining should not be classified as an organized crime. However, as evidenced in this report, the illegal gold mining camps operate in a highly organized manner.

MAAP 59: Power of “Small Satellites” from Planet

Posted on by dcadmin

The company Planet is pioneering the use of high-resolution “small satellites” (Image 59a). They are a fraction of the size and cost of traditional satellites, making it possible to produce and launch many as a large fleet. Indeed, Planet now operates 149 small satellites, known as Doves, the largest fleet in history. The Doves capture color imagery at 3-5 meter resolution, and will line up (like a string of pearls) to cover everywhere on Earth’s land area every day.

Over the past year, MAAP* has demonstrated the power of Planet imagery to monitor deforestation and degradation in near real-time in the Amazon. A consistent flow of new, high-resolution imagery is needed for this type of work, making Planet’s fleet model ideal. Below, we provide a recap of key MAAP findings based on Planet imagery, for a diverse set of cases including gold mining, agriculture deforestation, logging roads, wildfire, blowdowns, landslides, and floods.**

*MAAP has been fortunate to have access to Planet imagery via the Ambassador program.

Illegal Gold Mining

Image 59b. Data: Planet, SERNANP

We used Planet imagery to closely track the recent illegal gold mining invasion of Tambopata National Reserve, a mega-diverse protected area in the southern Peruvian Amazon. Image 59b is a GIF showing the full invasion: from the initial invasion in January 2016, to subsequent deforestation advances in July and November 2016, and the most recent image in March 2017. The total deforestation from the invasion is over 1,235 acres. These images were an important resource for authorities, civil society, and the media responding to the situation.

Illegal Agriculture Deforestation

Image 59c. Data: Planet, SERNANP

We used Planet imagery to document numerous cases of small-scale deforestation for illegal agricultural practices. These examples are important because, cumulatively, small-scale deforestation represents the vast majority (80%) of forest loss events in the Peruvian Amazon (see MAAP Synthesis #2). Image 59c shows the rapid appearance of several new agricultural plots between May (left panel) and June (right panel) 2016 within an important natural protected area in the central Peruvian Amazon, El Sira Communal Reserve.

Logging Roads

Image 59d. Data: Planet

We used Planet imagery to show the rapid construction of logging roads. For example, Image 59d shows the construction of a logging road in the buffer zone of an important national park in the central Peruvian Amazon (Cordillera Azul) between November 2015 (left panel) and July 2016 (right panel).

Wildfire

Image 59e. Data: Planet

Planet imagery was also an important resource to monitor the intense wildfires in Peru last year. Image 59e shows forest loss from an escaped agricultural fire in the northern Peruvian Amazon between May (left panel) and October (right panel) 2016. Note the imagery even caught the smoke from the fires in September (middle panel).

Blowdowns

Image 59f. Data: Planet

We used Planet to help document a little-known, but important, type of natural forest loss in the Peruvian Amazon: blowdown due to strong winds from localized storms known as “hurricane winds.” Image 59f shows a high-resolution view of a recent major blowdown event between January (left panel) and August (right panel) 2016 in the northern Peruvian Amazon.

Landslides

Image 59g. Data: Planet

Planet imagery recently revealed an interesting natural phenomenon: a major landslide within a remote, rugged section of Peru’s newest national park, Sierra del Divisor. Image 59g shows the area between October 2016 (left panel) and March 2017 (right panel).

Floods

Image 59h. Data: Planet

Finally, Planet imagery played a key role in monitoring the impacts of the recent deadly floods that hit the northern Peruvian coast. Image 59h shows the rapid flooding of agricultural plots along a river in northern Peru between February (left panel) and March (right panel) 2017.
