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

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 […]


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

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 […]


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

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 […]


MAAP #68: 2017 Deforestation Hotspots in The Peruvian Amazon (Part 2)

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 […]


MAAP #66: Satellite Images of Belo Monte Dam Project (Brazil)

The Belo Monte hydroelectric dam complex, located on the Xingu River in the state of Para in the eastern Brazilian Amazon (see Image 66a), has been controversial since its inception over 15 years ago, due to both environmental and social concerns related to building and operating one of the largest dams in the world in a sensitive environment. […]


MAAP #65: Deforestation Hotspots Of 2017 in The Peruvian Amazon

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 […]


MAAP #64: Good News Deforestation Stories (Peruvian Amazon)

  We admit that most MAAP stories are about the bad news of Amazon deforestation. But fortunately    there is good news as well. Here we highlight 5 good news stories from the Peruvian Amazon that show how near real-time monitoring may lead to halting deforestation from emerging threats, such as gold mining and large-scale agriculture […]


MAAP #63: Patterns of Deforestation in the Colombian Amazon

We are excited to present our initial analysis of the Colombian Amazon, a work that reflects an important collaboration with our colleagues at Amazon Conservation Team. It is also our first report in the more interactive “Story Map” format. This report has two objectives: 1) Illustrate the major deforestation hotspots in the Colombian Amazon between 2001 and 2015 […]


MAAP #62: Fire, Rain, And Deforestation in The Peruvian Amazon

In 2016, Peru experienced an intense forest fire season (MAAP #52, MAAP #53). A leading hypothesis was that intense drought facilitated the escape of agricultural burns. To investigate, this report analyzes the dynamic between fires and precipitation over the past 15 years, finding a strong temporal correlation (Image 62a). We also investigate the link between fires […]


MAAP #61: Illegal Gold Mining Decreases in Tambopata National Reserve

In the previous MAAP #60, we showed the rapidly increasing illegal gold mining deforestation in the buffer zone of Tambopata National Reserve. In contrast, here we show that the rate of illegal gold mining deforestation is decreasing within Tambopata National Reserve, due to the active interventions by the Peruvian Government. Tambopata is an important protected […]
