Small farmers play big role in felling Peru rainforest - satellite maps | Daily Mail Online

D eforestation in the Peruvian Amazon has risen this century - destroying an area of rainforest 14 times larger than Los Angeles - with small farmers behind most of the cutting, according to a new analysis of satellite maps.

Small farmers account for about 80 percent of Peru’s forest loss, the Monitoring of the Andean Amazon Project (MAAP), a Washington, D.C.-based research group, said on Wednesday.

“One of the big findings of this report is that deforestation is not driven by sexier issues such as large-scale oil palm (plantations) or dams, but widespread small-scale agriculture,” said Matt Finer, MAAP’s director.

Small producers clearing forests for farms or cattle grazing along with logging roads and illegal gold mining have caused Peru to lose 1,800,000 hectares of Amazon rainforest since 2001 and the trend is steadily increasing, the analysis said.

Gold mining deforestation in Peruvian reserve surpasses 450 hectares

n the past two months, another 100 hectares of tropical rainforest have been demolished in Tambopata National Reserve, where deforestation from illegal gold mining in the reserve now exceeds 450 hectares – 4.5 square kilometers. This could mean trouble for the region’s wildlife – some 600 species of birds, 1,200 species of butterflies, and 200 species of mammals inhabit Tambopata.

Monitoring of the Andean Amazon Project (MAAP) has been monitoring Tambopata since November 2015, when deforestation was first detected within its borders. According to MAAP’s recent analysis, mining continues in four regions along the Malinowski River, which forms the northern border of the reserve. MAAP researchers quantified the recent uptick in mining-driven deforestation by analyzing high-resolution satellite imagery from July and September within the reserve.

According to Matt Finer, who heads up the MAPP project, illegal mining has a clear signature recognizable through satellite imagery.

Identifying the drivers of Amazon deforestation through high-tech maps and stories

The Monitoring of the Andean Amazon Project (MAAP), launched in 2015 by the Amazon Conservation Association (ACA) and its Peruvian counterpart, Asociación para la Conservación Amazónica (ACCA), creates and presents maps from a near-real-time, high-resolution deforestation monitoring system. Matt Finer, who leads the project, initially came to ACA to help quantify threats to the Amazon—“instead of just saying oil drilling or dams are bad, quantifying impacts to see if and how they are bad”.

As Finer puts it, the MAAP team scours remote sensing data, primarily satellite images of varying resolutions, for new areas of deforestation and revisits known deforestation hotspots. Having seen the power of the timeliness of both monitoring and showing deforestation, the project focuses on high-resolution, high-frequency forest monitoring.

We spoke with Finer about the MAAP project and his team’s capacity to combine several new remote sensing technologies to monitor forest change in Peru. In a second part of this interview, we’ll highlight Finer’s thoughts on the rapid advance of technology in the remote sensing sector and its application to monitoring Amazon forests.
