In the Peruvian Amazon, the widespread illegal logging is difficult to detect with satellites because it is selective for high-value species (not clearcutting).
It is possible, however, to detect the associated logging roads.
In this report, we present a novel technique to identify illegal logging: analyze new logging roads in relation to detailed land use data available from government agencies.
Thus, our new method detects the crime in real-time and preventive action is still possible. This is important because when an intervention against illegal logging normally occurs, stopping a boat or truck with illegal timber, the damage is done.
This analysis has two parts. First, we identified the new logging roads built in the Peruvian Amazon during 2019, updating our previous work for 2015-18 (see Base Map).
Second, we analyzed the new logging road data in relation to governmental land use information in order to identify possible illegality.
This data is from 2019, but we are now applying this technique in real time during 2020.
Logging Roads 2019
The Base Map illustrates the location of logging roads built in the Peruvian Amazon during the last 5 years.
Previously (MAAP #99), we documented the construction of 3,300 kilometers of logging roads between 2015 and 2018.
Here, we estimate the construction of an additional 1,500 kilometers in 2019 (see red).
Note that forest roads are mainly concentrated in the Ucayali, Madre de Dios and Loreto regions.
Below, we show three types of possible illegality that detected in 2019:
- Logging roads in areas without forestry concessions or permits (Cases 1-2).
. - Logging roads in existing forest concessions, but whose current status is defined as “Non-Active or Undefined” (Cases 3-5).
. - Logging roads in Native Communities (Case 6).
Cases of Possible Illegality
Logging roads in areas without forestry concessions or permits
Case 1. We detected the opening of a new logging road network (55 km) in an area without forestry concessions or permits, between the limits of the Loreto and San Martín regions. The image shows the digitized logging roads (red, left panel), and non-digitized satellite image (right panel). The arrows provide reference points between panels.
Case 2. We detected the construction of a new logging road network (5.8 km) in the buffer zone of Asháninka Communal Reserve, reaching only 300 meters from the protected area. The image shows the digitized logging roads (red, left panel), and non-digitized satellite image (right panel). The arrows provide reference points between panels.
Logging roads in existing forest concessions, but whose current state is labelled as “Non-Active or Undefined”
Case 3. We detected the construction of a new logging road (45.3 km) that crosses a native community and reaches a forest concession whose status is defined as “Undefined,” in the Loreto region just north of Pacaya Samiria National Reserve. The image shows the digitized logging roads (red, left panel), and non-digitized satellite image (right panel). The arrows provide reference points between panels.
Case 4. We detected the construction of a new logging road network (53.2 km), of which nearly half (21.4 km) crosses a forest concession whose status is defined is “Non Active”, near the town of Sepahua in the Ucayali region. The image shows the digitized logging roads (red, left panel), and non-digitized satellite image (right panel). The arrows provide reference points between panels.
Case 5. We detected the construction of a new logging road (17.7 km) in a forestry concession whose current status is defined as “Non Active,” in the Madre de Dios region. The image shows the digitized logging roads (red, left panel), and non-digitized satellite image (right panel). The arrows provide reference points between panels.
Logging roads in Native Communities
Case 6. We detected the construction of a logging road (23.4 km) within an indigenous community in the Ucayali region. We did not find evidence of a permit for this activity. The image shows the digitized logging roads (red, left panel), and non-digitized satellite image (right panel). The arrows provide reference points between panels.
Methodology
Our analysis included two main steps:
The first step consisted of evaluating linear patterns in the 2019 early warning and final forest loss data, available from Global Forest Watch (data from the University of Maryland) and Geobosques (data from the Peruvian Ministry of the Environment). From the linear patterns, we distinguished between logging access roads and other types of roads and highways. Logging roads tend to have linear patterns that branch into the interior of the forest where the commercial timber is found. Other types of roads have a more defined destination, such as towns or farms. Once logging roads were identified, we downloaded the associated high-resolution imagery (3 meters) from Planet Explorer and digitized the roads in ArcGIS. During this process, additional logging roads detected in the high resolution images were also digitized.
The second step focused on the legality analysis. The new logging road data were overlaid with other types of land use information, such as forestry concessions on the GeoSERFOR portal (SERFOR), permits and concessions on the SISFOR portal (OSINFOR), indigenous communities (IBC 2019), protected areas (SERNANP), population centers (INEI 2019), and official road networks (MTC 2018). For example, as shown above, this process identified logging roads near protected areas, within indigenous communities, and within non-active forest concessions.
We analyzed information on several websites now available from national and regional authorities, such as SISFOR (OSINFOR), GEOSERFOR (SERFOR), and IDERs (Spatial Data Infrastructure of Regional governments). These new resources provide valuable information, however may have limitations in ability to constantly update information on the status of concessions and forest permits, especially from regional governments.

Amazon Conservation’s sister organization Conservación Amazónica – ACCA, with support from Google.org, just finished up a two-year initiative that trained community members to use cutting-edge satellite and field technologies to combat deforestation in the southern Peruvian Amazon, now protecting over 150,000 acres of lowland forests.
Before this program, concessionaires and their communities lacked capacity to monitor these large, remote areas and a way to rapidly and safely report deforestation in their territories. Our innovative methodology of combining real-time satellite imagery analysis and drone field technology (which includes smartapps and other technologies developed by Google) with legal training, gave concessionaires the ability to detect and report deforestation as it happened in their territory. This is a stark contrast from before, when the only way to monitor thousands of acres of forests was through foot patrols that took days to complete.
Through this program, over 153,000 acres (62,000 hectares) of forests are now monitored and protected with technology by the local people we empowered. Moreover, technological kits were donated to each individual or local association, each containing a drone, a maintenance kit, a laptop and a printer, giving them the knowledge and tools needed to safeguard forests..
The project, led by our director of our Southwest Amazon Drone Center, Carlos Castañeda, will continue to provide technical support to maintain the donated drones and training to reinforce what they learned, as well as be available to answer any questions that may arise during monitoring and surveillance of their concessions. Thus, the continuity of the project and its sustainability are ensured.

For the past year our team in Bolivia and Peru have been working with EUROCLIMA+, an initiative of the European Commission focused on combating climate change in Latin America. We are working with local communities to pilot climate change resilience in their sustainable use of forest resources.
n Bolivia, coordinates this project. His team works in the northern part of Bolivia, where local communities heavily depend on these forest goods to make a living. “Almost all the families dedicate themselves to harvesting forest fruits, mainly the Brazil nut, which is their main economic activity.”
Tying the importance of conservation of these forests not only to climate change but also to economic sustainability of local and global economies is vital for countries and communities to see the value of forests. In fact, our area of work in Bolivia holds 85% of the Brazil nut production in the world, and keeping those forests standing through sustainable activities will have a significant impact in the fight against deforestation and carbon emissions.
A key aspect of our work with EUROCLIMA+ is recognizing how these sustainable forest economies help mitigate the effects of climate change on communities and on the planet, which hadn’t previously been as much on peoples’ minds. This pilot work is also helping local communities become aware of how climate is changing the forests on which they depend, so they can plan for their long-term, sustainable use, without needing to turn to destructive practices like timber extraction and cattle ranching if a harvesting season is affected by global warming. This involves not only making sure we have healthy forests, but also helping communities diversify their source of income sustainably, such as harvesting other complementary forest products like açaí berries and sustainably farming paiche fish.
The Escazú Agreement, a regional agreement on access to information, public participation and access to justice in environmental matters in Latin America and the Caribbean whose ratification is soon to be debated in Congress, has generated an intense reaction and discussion. There is a sector that affirms that this agreement would attempt against our sovereignty in the Amazon. Considering that if this agreement is ratified, the important decisions for the economic development of the country would remain in the hands of international spheres. On the other hand, others consider that such an agreement leads to improved information flow and citizen participation. Both are necessary for the development of the country, particularly in Peru where social and environmental conflicts have paralyzed many important works for the economy. Understanding the scope of the agreement and its true implications is crucial for the future of Peru.
How can the Escazú Agreement threaten national sovereignty, and in particular, with our Amazon? To begin with, this is a Latin American regional agreement, which has been signed by 22 democratic nations (including those Amazonian), and so far, has been ratified by 9 of them. The agreement clearly states that decisions are the affairs of each country, within their own regulatory frameworks. It also stipulates that in cases where the conflict is between States, these – and only under a bilateral agreement – can be submitted to arbitration by the International Court of The Hague, as an international instance. That court does not have jurisdiction for internal affairs of a country, such as those between private, communities and the State. The resolution of controversies within a country is another matter, and only after exhausting the national justice mechanisms, they can be resolved by resorting to international bodies, which have nothing to do with the Escazú agreement.







seedlings mixed with biochar. The first 1,250 seedlings were transplanted to a target area of 2.1 hectares (5.2 acres), which had been verified as an ideal area for restoration through reforestation using this species. A tractor and a short boat trip down the river helped bring the seedlings to their new home, where they were planted throughout the end of 2019.
