MAAP #43: Early Warning Deforestation Alerts in the Peruvian Amazon, Part 2

Posted on by dcadmin

In the previous MAAP #40, we emphasized the power of combining early warning forest loss GLAD alerts with analysis of high-resolution satellite imagery as part of a comprehensive near real-time deforestation monitoring system for the Peruvian Amazon.

In the current MAAP, we present 3 new examples of this system across different regions of Peru. Click on the images below to enlarge.

Example 1: Illegal Gold Mining in buffer zone of Bahuaja Sonene National Park (Madre de Dios)
Example 2: Logging Road in buffer zone of Cordillera Azul National Park (Ucayali/Loreto)
Example 3: Deforestation in Permanent Production Forest (Ucayali)

Example 1: Illegal Gold Mining in buffer zone of Bahuaja Sonene National Park (Madre de Dios)

In the previous MAAP #5, we discussed illegal gold mining deforestation along the upper Malinowski River, located in the buffer zone of the Bahuaja Sonene National Park. As seen in Image 43a, the upper Malinowski is just upstream of the areas invaded by illegal gold mining in Tambopata National Reserve and its buffer zone (see MAAP #39 and #31, respectively). In MAAP #5, we documented the deforestation of more than 850 hectares between 2013 and 2015 along the upper Malinowski. Here, we show that gold mining deforestation continues in 2016, with an additional loss of 238 hectares (806 acres). Insets A-C correspond to the areas featured in the high-resolution zooms below.

Example 2: Logging Road in buffer zone of Cordillera Azul National Park (Ucayali/Loreto)

In the previous MAAP #18, we discussed the proliferation of logging roads in the central Peruvian Amazon in 2015. Here, we show the expansion of two of these logging roads in 2016. (see Image 43e). Red indicates construction during 2016 (47 km). Insets A1-A3 correspond to the areas featured in the high-resolution zooms below. Note that the northern road (Inset A3) is within the buffer zone of Cordillera Azul National Park. Evidence suggests that this road is not legal because it extends out of the permited area (see MAAP #18 for more details).

The following images show, in high-resolution, the rapid construction of these logging roads. Image 43f shows the construction of part of the southern road (Inset A1), and the deforestation for a nearby agricultural parcel, between April (left panel) and July (right panel) 2016. Image 43g shows the construction of 1.8 km in just three days along this same road (Inset A2) between July 21 (left panel) and July 24 (right panel) 2016.

Example 3: Deforestation in Permanent Production Forest  (Ucayali)

Image 43i shows recent deforestation of 136 hectares (336 acres) in 2016 in southern Ucayali region within areas classified as Permanent Production Forest and Foresty Concession. These types of areas are generally zoned for sustainable forestry uses, not clear-cutting, thus we question the legality of the deforestation. Tables A-B correspond to the areas featured in the high-resolution zooms, below.

MAAP #39: Gold Mining Deforestation Within Tambopata National Reserve Exceeds 350 Hectares

Posted on by dcadmin

Based on analysis of satellite imagery, we have documented that the deforestation due to illegal gold mining activities within Tambopata National Reserve (Madre de Dios region) now exceeds 350 hectares (872 acres) since the initial invasion in late 2015 (see Image 39a). Although the rate of deforestation has decreased since April, when the Peruvian government installed a permanent control post* in the area, it is clear that the deforestation continues to expand.  In the Image, we highlighted the most recent deforestation (June and July 2016) in red to emphasize the current fronts. Insets A and B indicate the areas detailed in the zooms below.

*A recent article in the New York Times highlighted the extreme difficulty faced by the Peruvian government in cracking down on the illegal mining. Yesterday, the leading Peruvian newspaper El Comercio reported that the control post has been abandoned due to lack of resources.

MAAP #36: New Gold Mining Frontier in the Northern Peruvian Amazon

Posted on by dcadmin

In several previous MAAP articles, we have detailed gold mining deforestation in the southern Peruvian Amazon. Here, we provide evidence of the first known case of gold mining deforestation in northern Peru.

A recent news article published by the Peruvian organization DAR reported that gold mining activity continues to increase in the Santiago River (see Image 36a), located in the Amazonas region of the northern Peruvian Amazon. The article also mentions that this gold mining activity is no longer restricted to the river, but is now entering the forest. There are mining concessions in the area, but according to a recent article published in The Guardian, the miners are not operating legally with permission from the concessionaire.

Here, we show the first satellite images that confirm that the mining activity is indeed causing deforestation along the Santiago River (see below). Click each image to enlarge.

MAAP #33: Illegal Gold Mining Alters Course of Malinowski River (border of Tambopata National Reserve)

Posted on by dcadmin

In MAAP #30, we described the illegal gold mining invasion of Tambopata National Reserve, an important protected area in the southern Peruvian Amazon (department of Madre de Dios). Here in MAAP #33, we show that illegal gold mining is also altering the course of the Malinowski River, which forms the natural boundary of the Reserve. Image 33a shows the two areas where we have documented a total artificial deviation (cutting) of 4.4 km (2.7 miles) of the river (see details below).

Zoom B: An Earlier Deviation of the Malinowski River

In February 2016, Peruvian specialists presented how mining activity had recently changed the natural course of the Malinowski river in the area indicated in Inset B*. Image 33d shows the progressive change: from the increase in mining activity along the normal course of the river in June 2013 (left panel), to the new stretch of riverbed in June 2015 (center panel), and finally to the expansion of mining activity along the previous course (right panel). The red dot indicates the same place over time in the three images. A total of 2.7 km was cut from the previous river course.

Ecological Impacts

According to Dr. Carlos Cañas**, coordinator of the Amazon Waters Initiative for Wildlife Conservation Society in Peru, the deviation of the natural course of the Malinowski River will have significant ecological impacts, including:

  • Although the Malinowski River’s course has natural movement, the changes documented in MAAP #33 definitely represent an artificial alteration caused by mining activity.
  • These artificial changes are altering the course of the Malinowski from one that is “narrow and defined” to one that is “wide and scattered.” This change impacts the river’s flood patterns by changing the intensity, timing, and frequency of flooding along the river’s banks. This implies an effect on the migratory behavior of many species of fish downstream, which receive and interpret signals from the river to guide vital functions like feeding and reproduction.
  • The river’s new wider course also causes the velocity of water downstream to decrease, which will lead to increased levels of sediment in the discharge zone of the largest tributary, the Tambopata. Given the nature of the Tambopata, this could provide the almost-permanent damming of the Malinowski, as greater volume of the Tambopata means more sedimentation at the mouth of the river. Among other things, this could hinder the entry of fish to their feeding zones.
  • As seen in Image 33d, fish access to certain areas will be interrupted by the blockade and closure of channels. Also, the connection between the floodable forest and the river channel is completely altered, if not interrupted, in this section of the river. Many fish species that eat fruit or vegetation from the adjacent forest depend on this seasonal connection for food.
  • The Malinowski River, since it is a tributary of the Tambopata River, has natural áreas that are crucial to the reproduction of many local species. Its tributary streams represent habitats that differ from the main river and harbor an incredible variety of fish and invertebrates that contribute to the biodiversity of the river basin. These streams have little sediment, and are thus highly transparent. Mining will destroy or drastically alter these environments, severely impacting this biodiversity.

MAAP #31: Deforestation Continues Expansion in La Pampa (buffer zone of Tambopata National Reserve)

Posted on by dcadmin

Illegal gold mining deforestation continues to expand in La Pampa, an area located in the buffer zone of Tambopata National Reserve in the Madre de Dios region. Here, we present a series of high-resolution (0.5 m) images that clearly illustrate this expansion. Image 31a shows the large, expanding mass of deforestation in La Pampa (as of November 2015) in relation to the Tambopata National Reserve and its buffer zone. Insets A and B indicate the high-resolution zoom areas, where further below we show the rapid deforestation of 76 hectares (188 acres) between November 2015 and April 2016.

MAAP #30: Gold Mining Invasion of Tambopata National Reserve Intensifies

Posted on by dcadmin

As described previously in MAAP #21, the illegal gold mining invasion of the Tambopata National Reserve began in late 2015. Here in  MAAP #30, we confirm that this invasion continues to intensify in 2016.

Image 30a shows the invasion zone, where we document that the illegal mining is advancing on seven fronts within the northwest section of the reserve and has thus far directly caused the deforestation of 130 hectares (320 acres) since September 2015. Below, we show high-resolution zooms of fronts 1-5 (Inset A) and a major mining camp recently established just outside of the Reserve (Inset B).

Using Radar to Confirm Invasion Continues

In early 2016, the Peruvian government led two major interventions (on January 21 and February 23, respectively) against the illegal miners operating in the interior of the Reserve. However, Image 30f shows in red the continued advance of deforestation (44 hectares) between March 1 (left panel) and March 25 (right panel). In other words, using radar technology (which can pierce through cloud-cover) we can confirm that deforestation continued to advance after the government interventions.

MAAP #25: Deforestation Hotspots in the Peruvian Amazon, 2012-2014

Posted on by dcadmin

Deforestation continues to increase in the Peruvian Amazon. According to the latest information from the Peruvian Environment Ministry1, 2014 had the highest annual forest loss on record since 2000 (177,500 hectares, or 438,600 acres per year). 2013 and 2012 had the third and fourth-highest annual forest loss totals, respectively (behind only 2009).

To better understand where this deforestation is concentrated, we conducted kernel density estimation. This type of analysis calculates the magnitude per unit area of a particular phenomenon (in this case, forest loss).

Image 25a shows the kernel density map for forest loss in the Peruvian Amazon between 2012 and 2014 and reveals that recent deforestation is concentrated in a number of “hotspots” in the departments of Loreto, San Martin, Ucyali, Huanuco, and Madre de Dios.

Insets A-D highlight four areas with high densities of forest loss described in previous MAAP articles. We are currently studying the other high density deforestation areas not included in the insets.

Inset A (from Image 25a) indicates the deforestation of over 2,000 hectares (4,940 acres) on property owned by the company United Cacao (through its wholly owned Peruvian subsidiary, Cacao del Peru Norte) near the town of Tamshiyacu in the department of Loreto. MAAP #9 demonstrated that much of this deforestation took place at the expense of primary forest. Image 25b highlights this area, showing the forest loss between December 2012 (left panel) and September 2013 (center panel; the pinkish areas indicate recently cleared forests). The right panel shows the cumulative deforestation between 2012 and 2014. See MAAP #9 and MAAP #2 for more details.

Inset D (from Image 25a) indicates the extensive illegal gold mining deforestation in the buffer zone of Tambopata National Reserve in the department of Madre de Dios. Image 25e highlights this area, showing the forest loss between September 2011 (left panel) and September 2014 (center panel; the lighter areas indicate recently cleared forests). The right panel shows the cumulative deforestation between 2012 and 2014 (4,738 hectares, or 11,700 acres). See MAAP #1 for more details.

It is important to emphasize that in this case, extensive deforestation continued in 2015. See MAAP #12 and MAAP #24 for more details.

Methodology

We conducted this analysis using the Kernel Density  tool from Spatial Analyst Tool Box of ArcGis 10.1 software. Our goal was to emphasize local concentrations of deforestation in the raw data while still representing overarching patterns of deforestation between 2012 and 2014. We accomplished this using the following parameters:

Search Radius: 15000 layer units (meters)

Kernel Density Function: Quadratic

Cell Size in the map: 200 x 200 meters (4 hectares)

Everything else was left to the default setting.

MAAP #24: Illegal Gold Mining Penetrates Deeper into Tambopata National Reserve

Posted on by dcadmin

*Note: During the preparation of this analysis, the Peruvian government conducted an operation against the illegal gold mining activity in the area described below (see this news article in Spanish for more information).

In MAAP #21, we revealed, using high-resolution images, the first sign of an invasion into the Tambopata National Reserve (an important natural protected area in the southern Peruvian Amazon) by illegal gold mining activities. Here in MAAP #24, we show two additional types of satellites imagery (due to lack of new high-resolution image) indicating that the illegal gold mining deforestation continues to penetrate deeper into the Reserve.

Image 24a. Landsat images showing the expansion of deforestation inside the Tambopata National Reserve between December 2015 (left panel) and January 2016 (right panel). Data: USGS, SERNANP.

Image 24a shows a comparison between two Landsat images (30 m resolution) indicating that the deforestation continued to increase within the Reserve between December 2015 (left panel) and January 2016 (right panel). The red circles indicate the general location of the newly deforested areas, which appear pink (soil without forest cover) and blue (wastewater pools) in contrast to the green (standing forest). The deforestation inside the Tambopata National Reserve between December 2015 and January 2016 is approximately 20 hectares (49 acres).

Image 24c shows, for the first time in MAAP, information from a radar satellite (Sentinel-1 from the European Space Agency). Unlike multi-spectral Landsat imagery that is vulnerable to clouds blocking the view, radar imagery is useful year-round (even the Amazon rainy season) because it can penetrate through cloud cover. In the displayed images, the shades of gray are related to the topography and the height of the forest. Lower areas, such as recently deforested lands and bodies of water, appear darker (almost black) in color, while higher areas such as standing forests appear lighter in color. Image 24c confirms the increase in deforestation between November 2015 (left panel) and January 2016 (right panel) within the area indicated above (see the red boxes).

MAAP #21: Illegal Gold Mining Deforestation Enters Tambopata National Reserve (Madre de Dios, Peru) [High-Resolution View]

Posted on by dcadmin

*Note: During the review process for this article, a major operation against illegal mining activities was carried out by the Peruvian government in the area described below.

Image 21a illustrates a recent illegal gold mining invasion of the Tambopata National Reserve. Tambopata is an important protected area in the southern Peruvian Amazon (department of Madre de Dios). Image 21a compares two high-resolution (0.5 m) images taken two months apart over the same area along the northern border of the reserve. One can clearly see the beginning of the illegal gold mining activity and deforestation within the reserve between September (left panel) and November (right panel) 2015. For more context regarding the area in question, see the yellow box in Image 21b.

Reference Map

Image 21b is a reference map showing the above detailed area in the larger context between the northern border of the Tambopata National Reserve and the illegal gold mining zone known as La Pampa. The yellow box corresponds to the area detailed in Image 21a. Note that the original boundary of the reserve created in 2000 no longer coincides with the route of the Malinowski River due to its natural movement over time.

Deforestation Data

Image 21c presents an updated analysis of the deforestation in the area between La Pampa and the Tambopata National Reserve. In this specific area, we documented the deforestation of 2,518 hectares (6,222 acres) between 2013 and 2015, the vast majority of which is clearly linked to illegal gold mining activities. The majority of this recent deforestation has occurred in La Pampa, a bit north of the reserve (but within its buffer zone). However, recent deforestation has also occurred along the Malinowski river, which forms the northern boundary of the reserve in this area.

In MAAP #5, we described the intensifying deforestation along the Upper Malinowski River in the department of Madre de Dios, Peru. Here in MAAP #19, we update this information and confirm that the deforestation continues at a rapid pace. This finding is based on analysis of three high-resolution images between September 2014 and November 2015. As described below, we document the deforestation of 392 hectares (969 acres) between September 2014 and November 2015 due to gold mining along the Upper Malinowki River.

Image 19a shows a comparison of two high resolution (0.5 m) images taken one year apart over the same area along the Upper Malinowski River (left panel is from September 2014, while the right panel is from September 2015). Comparison analysis of these images reveals two primary findings. First, deforestation is rapidly spreading upstream along the Upper Malinowski and its tributaries.

Second, this deforestation is nearing the border of the Bahuaja Sonene National Park boundary (see Image 19b).

Deforestation Analysis

Image 19c is a detailed deforestation analysis between the two images. We documented the deforestation of 352 hectares (870 acres) due to gold mining activities between September 2014 and September 2015 along the Upper Malinowski (note: this calculation covers the area displayed in Image 19a).

During preparation of this article, a new high resolution image over the same area from November 2015 became available. As an indication of how rapidly the gold mining is advancing, we documented an additional deforestation of 40 hectares (99 acres) between September and November 2015.

Thus, we documented a total deforestation of 392 hectares (969 acres) between September 2014 and November 2015 along the Upper Malinowki.

Two Gold Mining Deforestation Fronts

The Upper Malinowki is just west (and upstream) of the mining zone known as La Pampa featured in MAAP articles #1, #12, and #17. These currently appear to be the two major gold mining deforestation fronts in Madre de Dios. Image 19b illustrates the general location of these two areas (“C” indicates La Pampa and “D” indicates the Upper Malinowski). Note that La Pampa is within the buffer zone of the Tambopata National Reserve and the Upper Malinowski is within the buffer zone of the Bahuaja Sonene National Park.
