MAAP #76: Proposed Road would cross Primary Forest along Peru-Brazil Border

Posted on by Ana Folhadella

In December 2017, the Peruvian Congress approved a bill that declared it in the national interest to construct new roads in the border zone of Ucayali region, which shares a remote border with Brazil.

The main proposed road in this border area would cover 172 miles and connect the towns of Puerto Esperanza and Iñapari, in the Ucayali and Madre de Dios regions, respectively. Image 76a, a mosaic of satellite images from July 2017, illustrates just how remote and intact is the area surrounding the proposed road route.

Indigenous organizations and the Ministry of Culture have warned that the road would have major impacts on the indigenous peoples in voluntary isolation that are documented to inhabit parts of this remote area.

In this report, we add new information that complements the evaluation of possible impacts by calculating how much primary forest would be threatened as a result of road construction. We found that around 680,000 acres (275,00 hectares) of primary forest are at risk. Much of this area is within protected areas and a reserve for isolated indigenous groups.

 

Primary Forest

Image 76b. Data: GLCF/GSFC 2014, Hansen/UMD/Google/USGS/NASA, UMD/GLAD, PNCB/MINAM, UAC/ProPurús, SERNANP

We generated a primary forest layer based on existing satellite-based forest cover and forest loss data (see Methodology section for more details). We define primary forest as areas with intact forest cover dating back to the earliest available satellite-based data, 1990 in this case.

Image 76b shows the major results:

  • Virtually the entire route (172 miles; 277 km) crosses primary forest (dark green). Note the proliferation of forest roads in recent years around Iñapari (red lines).
  • The road would cross 3 critical protected areas and indigenous reserves: Madre de Dios Territorial Reserve, Alto Purús National Park, and Purús Communal Reserve.

 

 

 

 

 

 

Primary Forest at Risk

The Interoceanic Highway, the main existing road in the area, has experienced substantial deforestation within 5 km* along the length of its route (Image 76c).

Using this estimate of impact range (10 km), we calculated that at least 274,727 hectares of primary forest would be at risk if this road is constructed.

*We estimate that approximately 80% of forest loss has occurred in a 5 km radius on both sides of the Interoceanic highway.

 

 

 

 

 

 

 

 

Methodology

To generate our primary forest layer, we combined three satellite-based data sources. As baseline, we used data from the Global Land Cover Facility (2014), which identifies forest cover as of 1990. We also used this dataset to remove areas with detected forest cover change between 1990 and 2000. Next, we removed areas with detected forest loss between 2001 – 2017 identified by Hansen/UMD/Google/USGS/NASA (Hansen et al 2013) and early warning data from GLAD alerts and the National Program of Forest Conservation of the Peruvian Environment Ministry (PNBC-MINAM). As a result, combining all datasets, this methodology defines primary forest as area with intact forest from the first available satellite-based data, 1990, until 2017.

MAAP #75: Pope to visit Madre de Dios, region with Deforestation Crisis (Peru)

Posted on by Ana Folhadella
Table 76. Data: PNBC/MINAM (2001-16), UMD/GLAD (2017, until the first week of November).

Pope Francis, as part of his upcoming visit to Peru in January, will visit the Madre de Dios region in the southern Peruvian Amazon. He is expected to address issues facing the Amazon and its indigenous communities, including deforestation.

In this article, we show that Madre de Dios is experiencing a deforestation crisis, due mainly to impacts from gold mining, small-scale agriculture, and roads.

Table 76 shows the increasing trend of annual forest loss since 2001, peaking in 2017. In fact, in 2017 forest loss exceeded 20,000 hectares (49,000 acres) for the first time, doubling the loss in 2008.*

The table also shows the ranking of Madre de Dios in respect to the annual forest loss compared to all other regions of the Peruvian Amazon (see red line). For the first time, Madre de Dios is the region with the second highest forest loss total, behind only Ucayali.

Next, we present a map of deforestation hotspots in Madre de Dios in 2017, along with satellite images of a number of the most intense hotspots.

*The total estimated forest loss in 2017 was based on early warnings alerts generated by the University of Maryland (GLAD alerts) and the Peruvian Environment Ministry (PNCB/MINAM). The estimate is 20,826 hectares as of the first week of November.

Deforestation Hotspots in Madre de Dios

Image 76 shows a map of deforestation hotspots in Madre de Dios in 2017, based on early warning forest loss data. The colors yellow (low), orange (medium/high), and red (very high) correspond to the areas with the highest concentration of alerts, i.e. the main deforestation hotspots of 2017. Note how the majority of the forest loss is concentrated along the recently paved Interoceanic highway.

Next, we show satellite imagery for 7 hotspots (Insets A-G) that together account for the deforestation of 6,000 hectares (15,000 acres). We show that the main deforestation drivers are gold mining and small-scale agriculture.

La Pampa (Inset A)

The area known as La Pampa continues to experience significant deforestation due to the advance of gold mining. Despite a series of field interventions by the Peruvian Government, we documented the deforestation of 1,385 acres (560 hectares) in 2017 (Image 76a). Since 2013, the total deforestation in La Pampa is 11,270 acres (4,560 hectares).

Image 76a. Data: Planet

Upper Malinowski (Inset B)

Upstream of La Pampa, the headwaters of the Malinowski River represent a second area devastated by the recent advance of gold mining. We documented the deforestation of 1,795 acres (726 hectares) in 2017 along the upper Malinowski (Image 76b). Since 2015, the total deforestation along the upper Malinowski is 5,260 acres (2,130 hectares).

Image 76b. Data: Planet

Santa Rita and Guacamayo (Insets C y D)

To the north of the La Pampa and Upper Malinowski mining areas, and on the other side of the Interoceanic highway, are two areas with significant recent deforestation due to small-scale agriculture. In these two areas, we documented the deforestation of 2,890 acres (1,170 hectares) in 2017 (Images 76c, 76d). Additional research focused on the exact type of crops is required, but local sources indicate an increase in papaya and cacao in the area.

Image 76c. Data: Planet, ESA
Image 76d. Data: Planet

Iberia (Inset E)

On the other side of Madre de Dios, along the Interoceanic Highway near the border with Brazil and Bolivia, is the town of Iberia. This area has become a major deforestation hotspot in recent years. We documented the deforestation of 2,250 acres (910 hectares) in 2017 (Image 76e). Since 2014, the total deforestation around Iberia is 6,795 acres (2,750) hectares. A large part of the deforestation is within forestry concessions, indicating that these concessions have been invaded. The cause of the deforestation is small-scale agriculture (specifically, according to local sources, corn, papaya, and cacao).

Image 76e. Data: Planet

Tahuamanu (Inset F)

To the west of Iberia, an isolated hotspot emerged caused by the rapid proliferation of logging roads. This hotspot is located within a forestry concession, but its impact is troubling due to the extension and density of the new road network. We estimate the construction of 130 km of new logging forest roads in this area in 2017 (Image 76f).

Image 76f. Data: Planet

Las Piedras (Inset G)

Finally, deforestation continues within two ecotourism concessions along the Las Piedras River, a remote area famous for its exceptional wildlife (see this video). We documented the deforestation of 300 acres (134 hectares) in 2017 (Image 76g). Since 2013, the total deforestation along the Las Piedras River is 1,495 acres (605 hectares). Note that the Las Piedras Amazon Center Ecotourism Concession represents an effective barrier against deforestation impacting the surrounding concessions. According to local sources, the main causes of deforestation are cacao plantations and cattle pasture.

MAAP Interactive: Deforestation Drivers in the Andean Amazon

Posted on by Ana Folhadella

Since its launch in April 2015, MAAP has published over 70 reports related to deforestation (and natural forest loss) in the Andean Amazon. We have thus far focused on Peru, with several reports in Colombia and Brazil as well.

These reports are meant to be case studies of the most important and urgent deforestation events. We often use forest loss alerts (known as GLAD) to guide us, and satellite imagery (from Planet and DigitalGlobe) to identify the deforestation driver.

Here we present an interactive map highlighting the drivers identified in all published MAAP reports. These drivers include gold mining, agriculture (e.g. oil palm and cacao), cattle pasture, roads, and dams (see icon legend below map). We also include natural causes such as floods and blowdowns (fire included under agriculture since most human caused). Furthermore, we highlight deforestation events within protected areas. Note that you can filter by driver by checking boxes of interest.

We hope the result is one of the most detailed and up-todate resources on patterns and drivers of deforestation in the Andean Amazon. Over the coming year we will continue to focus on Peru and Colombia, and begin to include Ecuador and Bolivia as well.

MAAP #74: Landslides in the Peruvian Amazon

Posted on by Ana Folhadella
Image 74. Base Map. Data: SERNANP

In addition to the human-caused deforestation emphasized in MAAP, there is also natural Amazonian forest loss. The causes include meandering rivers, wind storms (see MAAP #70), and the subject of this report: landslides.

Amazon landslides may be caused by heavy rains in rugged areas. Many landslides occur in protected areas, which often include steep and unstable areas.

Here, we show satellite images of 3 recent examples of large landslides in protected areas in the Peruvian Amazon. We document the natural forest loss of 685 acres (280 hectares) in these examples, indicating that landslides are an important natural phenomenon in the Amazon.

Example A: Sierra del Divisor National Park
Example B: Cordillera Azul National Park
Example C: Bahuaja Sonene National Park

 

 

 

 

 

Example A: Sierra del Divisor National Park

Image 74a shows landslides within Sierra del Divisor National Park between October 2016 (left panel) and October 2017 (right panel). The natural forest loss is 74 acres.

Natural Forest Loss in the Peruvian Amazon

The Resilient Amazon project, executed jointly by UNDP (United Nations Development Program) and the Peruvian protected areas agency (SERNANP), estimates that natural forest loss is around 2.95% of the total documented forest loss in Peru. This estimate is based on a detailed analysis in the central and southern Peruvian Amazon. If this finding is extrapolated to the entire Peruvian Amazon, there is an estimated natural forest loss of 11,365 acres (4,600 hectáreas) every year (based on the previous 5-year average of 159,000 hectares total forest loss).

MAAP #72: New Gold Mining Deforestation Zone in Peruvian Amazon: the Upper Malinowski (Madre de Dios)

Posted on by Ana Folhadella

In a series of previous reports (MAAP # 60), we have described the dire gold mining deforestation in the southern Peruvian Amazon, most notably in the area known as “La Pampa” (see Base Map). However, over the past 3 years another critical area has emerged in the region: the Upper Malinowski. This area is located near the headwaters of the Malinowski River, upstream of La Pampa (see Base Map).

Here, we show satellite images of the rapid advance of gold mining deforestation in two sectors of the upper Malinowski. In total, we document the deforestation of 3,880 acres (1,570 hectares) between 2015 and 2017 inside the buffer zone of the Bahuaja Sonene National Park.

Upper Malinowski – Sector A

Sector A has experienced the rapid deforestation of 704 acres (285 hectares) over just the past 2 years. Figure 72a shows satellite images (courtesy of the company Planet) of this rapid mining deforestation between October 2015 (left panel) and October 2017 (right panel). In addition, we show a very high resolution image (0.32 meters) over an active part the sector (Inset A2); note the visible presence of mining camps and organized mining pits. There are no mining concessions in this sector, thus all mining activity is illegal.

MAAP #71: Gold Mining Threatens Amarakaeri Communal Reserve, Again

Posted on by Ana Folhadella

In an earlier series of articles (MAAP #6, MAAP #44, MAAP #64), we showed the illegal gold mining invasion of a section of Amarakaeri Communal Reserve (see yellow box in Base Map), as well as the rapid response by authorities to remove the miners. It was an important case given that Amarakaeri is an important Peruvian protected area, co-managed byPeru’s protected areas agency (SERNANP) and indigenous communities (represented by the ECA Amarakaeri).

However, here we highlight the rapid advance of gold mining deforestation towards another section of Amarakaeri Communal Reserve, in the region of Cusco to the south (see purple box in Base Map).

*According to a statement from SERNANP, they are jointly coordinating with the ECA Amarakaeri and competent authorities such as the National Police, Prosecutor’s Office, and National Forest Service (SERFOR), regarding actions to stop the advance of illegal gold mining, and generating and comprehensive solutions to the problem.

Image 71. Base Map

Advance of New Gold Mining Invasion

Over the past year, gold mining has rapidly advanced in the buffer zone of the Amarakaeri Communal Reserve, along a tributary of the Nuciniscato River in the Cusco region. This mining activity has caused the deforestation of 158 acres (64 hectares) of primary Amazon rainforest between September 2016 and September 2017 (Image 71a). The most recent deforestation, during September 2017, is only 1 km from the border of the Amarakaeri Communal Reserve.

Image 71a. Data: Planet, SERNANP

Below, we show a series of satellite images (obtained from the company Planet) showing the rapid advance of gold mining deforestation towards the Communal Reserve during 2017 (May, July, August, and September). To enlarge, click the bottom right of the images.

MAAP #70: “Hurricane Winds” in the Peruvian Amazon, a 13 Year Analysis

Posted on by Ana Folhadella

In an earlier report, MAAP #54, we described the natural phenomenon of “hurricane winds” in the Peruvian Amazon. These strong wind storms (not true hurricanes) cause a chain reaction of fallen trees and may blow down hundreds of acres of Amazonian forest (see Drone Image below).

This report presents an analysis of the frequency and intensity of hurricane winds in the Peruvian Amazon over the past 13 years (2005-17). The analysis is based on the annual forest loss data and early warning alerts data.

Drone Image. Source: ACCA

Temporal Patterns

Graph 70 shows the temporal patterns for two important annual variables: Number of hurricane wind events (red line) and the total forest blowdown area (green bars). We found a total of 37 hurricane wind events resulting in the blowdown of 19,275 acres (7,800 hectares) between 2005 and 2017 in the Peruvian Amazon. Note the major increase in 2013, 2014, and 2016; these three years account for two-thirds of the total events and blowdown area.

Graph 70. Data: MAAP.

Spatial Patterns

Image 70. Data: MAAP, SERNANP

Image 70 shows the spatial patterns of the hurricane winds. Note the following highlights:

– Most of the events occurred in the regions of Loreto and Madre de Dios.

– In Loreto, most of the events occurred since 2013; in Madre de Dios, most occurred since 2016.

– There were 7 major events over 150 hectares (370 acres) each. The largest of these events was 2,255 acres (912 hectares).

 

 

 

 

 

 

 

 

 

Satellite  Images

Below, we show satellite images of some of the major hurricane wind events. The letters (A-F) correspond the the locations in Image 70.

Data: Planet, NASA/USGS

Methodology

  1. To determine the natural forest loss areas, we utilized the forest loss data from the GEOBOSQUES’ portal of the PNCBCC – MINAM, as well as the forest loss data from the University of Maryland, through their Global Forest Change portal that provides data from 2001 – 2015. We decided to evaluate both database due to the different criteria for excluding areas in remote locations. For the analysis, it was only considered events resulting in forest loss of 30 hectares or higher.
  2. We determined the natural forest loss through the visual interpretation of the fan-shaped pattern of these natural phenomena. This pattern was then validated with the high and medium resolution images from the years where the loss were detected.
  3. Identifying the period in the year where these events happened, for the years 2015, 2016 and 2017 was determined initially under the Julian calendar that is compatible with the table of attributes of the forest loss database. Consequently, we utilized major series of continuous high resolution images to reduce the timeframe in which these event could have occurred.

MAAP #69: Alarming Deforestation Patterns in the Central Peruvian Amazon

Posted on by Ana Folhadella
Image 69. Base Map.

Thanks to early warning forest loss alerts (known as GLAD), we recently detected several alarming new deforestation patterns within remote, primary forest of the central Peruvian Amazon.

They appear to be related to medium or large-scale agricultural activities due to their distinct characteristics: straight access paths extending from secondary roads built deep into primary forest, and deforestation of rectangular/square plots.

These patterns are significant because they are very different than the usual patterns observed with small-scale agriculture in the Peruvian Amazon: scattered plots with no major linear features.

Here, we show satellite images of 3 areas in the central Peruvian Amazon (see Base Map) that have recently experienced these alarming patterns, and deserve urgent attention due to the threat of rapid deforestation of large swaths of primary forest.*

 

 

 

 

 

 

 

North of Imiria Regional Conservation Area (Ucayali)

Image 69a. Data: Planet

Just north of Imiria Regional Conservation Area (Ucayali region), we documented the construction of a new access road and deforestation of 445 acres (180 hectares) of primary forest between June and September 2017 (Image 69a). In the September image (right panel), the linear features of the access path and agriculture plots are clearly seen. It also appears that there is much potential for continued deforestation into the surrounding primary forest. Sources indicate that this deforestation is linked to a farming association, however it is not yet known for what type of crop. The deforestation is only 2 km away from the Imiría Regional Conservation Area.

Nueva Requena (Ucayali)

Image 69b. Data: Planet

In the remaining primary forests of the Nueva Requena district (Ucayali region), we documented the clearing of three linear paths, totaling 9 km, and the subsequent deforestation of 188 acres (76 hectares) (Image 69b). These paths are located within national forestry lands (known as Permanent Production Forest), indicating that the new deforestation is part of an illegal invasion. It is important to note that this area was recently in the news regarding the killing of six farmers over land rights dispute and is close to controversial large-scale oil palm projects (MAAP #41).

Orellana (Loreto)

Image 69c. Data: Planet

Further north, near the town of Orellana (Loreto region), we documented the rapid clearing of a series of linear paths, totaling 19 km, followed by the deforestation of 255 acres (104 hectares) of primary forest (Image 69c). Note the deforestation in the form of numerous rectangular plots. As in the above examples, there is much potential for continued deforestation into the surrounding primary forest.

Notes

*According to the Supreme Decree (No. 018-2015-MINAGRI) approving the Regulations for Forest Management under the framework of the new 2011 Forestry Act (No. 29763), the official definition of primary forest in Peru is: “Forest with original vegetation characterized by an abundance of mature trees with species of superior or dominant canopy, which has evolved naturally.” Using methods of remote sensing, our interpretation of that definition are areas that from the earliest available image are characterized by dense closed-canopy coverage and experienced no major clearing events.

MAAP #68: 2017 DEFORESTATION HOTSPOTS IN THE PERUVIAN AMAZON (Part 2)

Posted on by Ana Folhadella
Image 68. Base map. Data: PNCB/MINAM, UMD/GLAD, SERNANP.

In a previous report, MAAP #65, we presented information about deforestation hotspots in 2017 in the Peruvian Amazon, based on early warning alert data from January until mid-July.

Between July and August, the amount of alerts greatly increased, likely due to arrival of the dry season. Thus, this report includes new updated data until mid-August.*

We find new deforestation hotspots in the regions of Madre de Dios and Ucayali (see base map).** At the national level, we now estimate the forest loss of 111,200 acres (45,000 hectares) thus far in 2017 (thru August 17).***

Below, we present satellite imagery of the following hotspots:

– La Pampa, Madre de Dios (Inset A)
– Guacamayo, Madre de Dios (Inset F)
– Iberia, Madre de Dios (Inset G)
– South of Sierra del Divisor, Ucayali (Inset H)
– Nueva Requena, Ucayali (Inset I)

**The data were generated by the National Program of Forest Conservation for Climate Change Mitigation, Peruvian Ministry of Environment (PNCB/MINAM).

**See Hotspots A-E in MAAP #65

***We emphasize that our calculations are just estimates. Official forest loss data are produced annually by the Peruvian Ministry of Environment.

 

La Pampa, Madre de Dios (Inset A)

Illegal gold mining deforestation continues to expand in the buffer zone of Tambopata National Reserve in the southern Peruvian Amazon. The Peruvian Government has conducted several interventions this year, most notably in July. However, between July and August we documented the additional loss of 67 acres (27 hectares), increasing the 2017 total deforestation in this zone to 1,280 acres (517 hectares). Image 68a is a GIF illustrating the gold mining deforestation from January to September 2017.

Image 68a. Data: Planet

Guacamayo, Madre de Dios (Inset F)

North of La Pampa, in another gold mining zone, known as Guacamayo, we have documented the rapid deforestation of 182 acres (74 hectares). This newly deforested area is located next to the mining zone (within a forestry concession), and appears to be caused by agricultural activity.

Image 68f. Data: Planet

Iberia, Madre de Dios (Inset G)

Around the  town of Iberia, located along the Interoceanica highway near the border with Brazil, has recently become a major deforestation hotspot (see MAAP #28 and MAAP #47). Between June and August 2017, we detected the deforestation of 1,075 acres (435 hectares). Much of this deforestation is within forestry concessions, indicating that the concessions have been invaded. The deforestation appears  to be caused by agriculture (according to local sources, the clearing is for corn plantations).

Image 68g. Data: Planet.

South of Sierra del Divisor, Ucayali (Inset H)

In the central Peruvian Amazon, just south of Sierra del Divisor National Park, we detected the new construction of 25 km of logging roads in the forestry concessions surrounding the park. We also detected the deforestation of 138 acres (56 hectares), close to the National Park’s limit for what appears to be agricultural activity.

Image 68h. Data: Planet, SERNANP

Nueva Requena, Ucayali (Inset I)

Also in the central Peruvian Amazon, in the Nueva Requena district near two controversial oil palm plantations (MAAP #41), we detected the deforestation of 1,130 acres (457 hectares) in state forestry lands (known as Permanent Production Forest). This includes 26 km of new logging and agricultural roads. It is important to note that this area was recently in the news regarding the killing of six farmers over land rights dispute.

MAAP #65: Deforestation Hotspots of 2017 in the Peruvian Amazon

Posted on by Ana Folhadella
Image 65. Data: MINAM/PNCB, UMD/GLAD, SERNANP, MAAP

In an earlier report, MAAP #40, we highlighted the power of combining early warning GLAD* alerts with analysis of high-resolution satellite images (for example, from the company Planet), as part of a comprehensive near real-time deforestation monitoring system.

In the current report, we analyze the GLAD alerts for the first half of 2017 (through July 17) to identify current deforestation hotspots in the Peruvian Amazon.** These alerts indicate an estimated total forest loss of 37,000 acres (15,000 hectares) thus far during the year.

Image 65 (see right) highlights the 2017 deforestation hotspots, defined here as areas with medium to high density of forest loss.

Below, we describe and show images of the most intense hotspots, indicated in red and orange.

These areas include:

  • Buffer zones of Tambopata National Reserve and Cordillera Azul National Park
  • Natural loss due to blowdowns from “hurricane winds,” in the Madre de Dios region
  • Northwest border with Colombia

 

 

 

 

Buffer Zone of Tambopata National Reserve 

Inset A indicates an area of high intensity deforestation due to gold mining activity in the buffer zone of Tambopata National Reserve in the southern Peruvian Amazon (Madre de Dios region). Image 65a shows the deforestation of 1,210 acres (490 hectares) in this area in 2017. The Peruvian government recently (early July) led a major raid in this area. However, the most recent satellite images (late July – early August) indicate that mining camps are still present in the area.

Hurricane Winds

Insets B and C indicate two areas in the southern Peruvian Amazon (Madre de Dios region) that experienced the natural forest loss of 980 acres (400 hectares) caused by hurricane winds, localized thunderstorms with strong winds. Images 65b and 65c show the recent 2017 forest loss. See MAAP #54 and MAAP #55 for more details about hurricane winds.

Buffer Zone of Cordillera Azul National Park

Inset D shows an area of medium intensity deforestation in the buffer zone of Cordillera Azul National Park, in the central Peruvian Amazon (San Martin region). Image 65d shows an example of the deforestation (138 acres) in this area in 2017. The main cause of the deforestation appears to be agricultural activity.

Northwest Border with Colombia

Inset E indicates a medium intensity hotspot in the extreme northern Peruvian Amazon (Loreto region), along the border with Colombia. The deforestation is approaching the limit of the Huimeki Communal Reserve. Image 65e shows the deforestation of 390 acres (158 hectares) in this area in 2017. The driver appears to be linked to agricultural activities and illicit crops (The United Nations has confirmed coca in this area).

Notes

*GLAD alerts are a powerful new tool to monitor tropical forest loss in near real-time. This early warning system, created by the GLAD (Global Land Analysis and Discovery) laboratory at the University of Maryland and supported by Global Forest Watch, was launched in March 2016 as the first Landsat-based (30-meter resolution) forest loss alert system (previous systems were based on lower-resolution imagery). The alerts are updated weekly and can be accessed through Global Forest Watch.

**We performed a kernel density estimation, an analysis that calculates the magnitude per unit area of a particular phenomenon, in this case, forest loss.
