MAAP #32: Large-Scale vs. Small-Scale Deforestation in the Peruvian Amazon

Posted on by dcadmin

In the previous MAAP #25 and MAAP #26, we illustrated deforestation hotspots in the Peruvian Amazon for the periods 2012-2014 and 2015*, respectively. Here in MAAP #32, we present a complementary analysis based on the size of deforestation events.

Graph 32a shows the comparative results of deforestation patterns between 2013 and 2015, indicating that:
– Small-scale (< 5 hectares) accounted for the vast majority of deforestation events (70-80%) each year.
– Medium-scale (5-50 hectares) accounted for approximately 20% of the deforestation events each year.
– Large-scale (> 50 hectares) deforestation was variable. In 2013, the year with the most activity of new cacao and oil palm plantations, it accounted for 8% of the deforestation events. In 2015 it was only 1%.

In summary, small- and medium-scale deforestation events represent more than 90% of the total and a constant threat, while large-scale deforestation events represents a latent threat. As described below, large-scale projects can quickly cause massive deforestation events, and should therefore remain a high priority.

*We have increased our deforestation estimate for 2015 to 163,238 hectares (403,370 acres), the second highest on record (behind only 2014). This estimate is based on GLAD alerts, produced by University of Maryland, Google, and Global Forest Watch.

Northern Peruvian Amazon

Image 32b shows a zoom of the northern Peruvian Amazon for 2013 (left panel) and 2015 (right panel). In general, there is a pattern of small-scale deforestation along the rivers of Loreto. Additionally, in 2013, there were large-scale deforestation events for a cacao project located to the southeast of the city of Iquitos (see MAAP #27 for more details) and for oil palm plantations along the border of Loreto and San Martin regions (see MAAP #16 for more details). In 2015, the expansion of deforestation continued in these areas, but at a medium-scale.

Central Peruvian Amazon

Image 32c shows a zoom of the central Peruvian Amazon for 2013 (left panel) and 2015 (right panel). In general, there is a concentration of small- and medium-scale deforestation between northwest Ucayali and southeast Huánuco. Additionally, in 2013, there is large-scale deforestation for two new oil palm plantations located northeast of the city of Pucallpa (see MAAP #4 for more details).

Southern Peruvian Amazon

Image 32d shows a zoom of the southern Peruvian Amazon for 2013 (left panel) and 2015 (right panel). In general, there is a pattern of small- and medium-scale deforestation along the Interoceanic highway in Madre de Dios. Additionally, there is the persistence of large-scale deforestation in southern Madre de Dios related to illegal gold mining (see MAAP #12 for more details).

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).

Invasion of Tambopata: Fronts 1-5

Image 30b shows the rapid expansion of deforestation in 5 of the fronts inside the Reserve between the end of January (left panel) and March (right panel) of 2016. This image corresponds to Inset A in Image 30a. Further below, Images 30c and 30d show high-resolution zooms of these 5 fronts.

Major Mining Camp Adjacent to Tambopata Reserve

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 #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 #29: Construction of New Road Between Manu National Park and Amarakaeri Communal Reserve (Madre De Dios)

Posted on by dcadmin

Here in MAAP #29, we describe the Nuevo Eden-Boca Manu-Boca Colorado road project in the southern Peruvian Amazon (Madre de Dios region). The objective of this article is to show the current state of construction and quantify the direct and indirect deforestation caused thus far by the road. This is a controversial road project because it cuts through the buffer zones of two important protected areas, the Amarakaeri Communal Reserve and Manu National Park*.

Image 29a. Data: SERNANP, USGS, MINAGRI, IBC, CLASlite, PNCB/MINAM, Hansen/UMD/Google/USGS/NASA, SPOT

Image 29a shows the general context of the area between Amarakaeri  and Manu where the road is being constructed. The yellow line indicates the section of road built in 2015 (11.6 km) between the towns of New Eden and Shipetiari (see right panel for high-resolution image of this construction). The red line indicates the new section under construction thus far in 2016 (21.8 km). Thus, in total, we have documented the construction of 33.4 km of road within the Amarakaeri Communal Reserve buffer zone. Finally, the pink line indicates the future road section planned to Boca Manu and then to Boca Colorado.

Road Construction in 2015

Image 29b shows a series of satellite images (Landsat) that illustrate the rapid road construction during 2015. The first two panels show the construction of 11.6 km between February (left panel) and October (central panel) 2015. The yellow arrows in the central panel indicate the direct deforestation (20 hectares) associated with construction of the route. The yellow circles in the right panel indicate the indirect (secondary) deforestation associated with the road (12 hectares). Thus, in total, we have documented the deforestation of 32 hectares (or 79 acres) associated with the road as of mid-March 2016.

New Road Construction in 2016

Image 29c shows the continued road construction (2.9 km) between January and mid-March 2016 (see orange arrows in the left panel). Moreover, using high-resolution imagery provided by Planet Labs, the right panel shows a new path (see red arrows) that is likely the leading edge of the current road construction. This path now extends an additional 19 km in the direction of Boca Manu (see Image 29d).
