A major deforestation surge continues in the northwest Colombian Amazon (MAAP #97). In 2018, it resulted in the loss of 199,000 hectares (491,700 acres)*, making it the most concentrated deforestation hotspot in the entire western Amazon (MAAP #100). Here, we provide a real-time...

For the 100th MAAP report, we present our first large-scale western Amazon analysis: Colombia, Peru, Ecuador, Bolivia, and western Brazil (see Base Map). We use the new 2018 data for forest cover loss, generated by the  University of Maryland (Hansen et al 2013)...

In the Peruvian Amazon, most of the logging is selective (not clearcutting), with the targets being higher-value species. Thus, illegal logging is difficult to detect with satellite imagery. In MAAP #85, however, we presented the potential of satellite imagery in identifying logging roads,...

Thanks to early warning forest loss alerts,* we are able to make an initial assessment of the 2018 deforestation hotspots in the Peruvian Amazon. The Base Map highlights the medium (yellow) to high (red) hotspots. In this context, hotspots are the areas with the...

  The Colombian Amazon is currently experiencing a deforestation surge (see graph). The surge started three years ago (2016) and peaked in 2017 with the highest annual deforestation on record (214,744 hectares).* Deforestation remains high in 2018: 156,722 hectares (based on early warning alert data).* If this estimate is confirmed,...

MAAP, an initiative of the organization Amazon Conservation, uses cutting-edge satellite technology to monitor deforestation in near real-time in the megadiverse Andean Amazon (Peru, Colombia, Ecuador, and Bolivia). The monitoring is based on 5 satellite systems: Landsat (NASA/USGS), Sentinel (European Space Agency), PeruSAT-1, and the companies Planet and DigitalGlobe. For more information about our...

When tropical forests are cleared, the enormous amount of carbon stored in the trees is released to the atmosphere, making it a major source of global greenhouse gas emissions (CO2) that drive climate change. In fact, a recent study revealed that deforestation and...

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...

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...

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...
