MAAP #78: Deforestation Hotspots in The Peruvian Amazon, 2017

Posted on by dcadmin

As we begin a new year, we make an initial assessment of 2017, estimating deforestation hotspots in the Peruvian Amazon based on early warning alert data.*

We estimate the annual forest loss of 354,410 acres (143,425 hectares) across Peru in 2017. If confirmed, this total represents the lowest in 5 years (average of 394,600 acres since 2012), and a decrease of 13% from last year.**

Deforestation, however, is still widespread. The base map shows the most intense hotspots (areas with highest density of forest loss).

The two main deforestation areas are clearly seen: the central Amazon (Ucayali/Huánuco regions) and the southern Amazon (Madre de Dios). Also, there are several additional hotspots scattered throughout the country.

We present satellite images (slider format) of the most intense hotspots. The images reveal that the main deforestation drivers include gold mining, oil palm, and general agriculture (crops and livestock).

The hotspots detailed below are:

A. Central Amazon (Ucayali/Huánuco)
B. Southern Madre de Dios
C. Iberia (Madre de Dios)
D. Northeast San Martín
E. Nieva (Amazonas)

MAAP #76: Proposed Road Would Cross Primary Forest Along Peru-Brazil Border

Posted on by dcadmin

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.

MAAP #75: Pope to Visit Madre De Dios, Region With Deforestation Crisis (Peru)

Table 75. 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.

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.

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

MAAP #73: United States’ Only National Tropical Rainforest Ravaged by Hurricane Maria (Puerto Rico)

MAAP usually focuses on deforestation in the Andean Amazon region, but has a larger interest in tropical forests in general. Thus, we present this analysis in that larger framework.

The New York Times recently reported that Hurricane Maria “obliterated” the United States’ only national tropical rain forest as the powerful Category 4 hurricane (with 150 mph winds) passed over Puerto Rico on September 20.

Here, we present a series of fresh satellite images from October that indeed show the severe impact to nearly all 28,400 acres of El Yunque National Forest (see Base Map). El Yunque is managed by the United States Forest Service and is the only tropical rain forest in the US national forest system.

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

Posted on by dcadmin

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.

MAAP #70: “Hurricane Winds” In the Peruvian Amazon, A 13 Year Analysis

Posted on by dcadmin

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.

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

Posted on by dcadmin

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.*

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.
