An inconvenient ground-truth

17 November, 2015 by (comments)

New deforestation hotspots point the finger at my favourite fruit I love Terra-i, but today I hate it. A lot. The system uses satellite images to track deforestation in the Amazon in near-realtime. It’s extremely accurate: if a bunch of trees come down somewhere – no matter how remote – Terra-i picks it up. Cool, right? Not today. CIAT’sRead More …

Cutting down on Amazon deforestation: Watch, think, and act

10 December, 2014 by (comments)

Reducing deforestation in the Amazon is possible – Brazil has done it. Now it’s the turn of other Amazon countries to do something. With Terra-i and other Global Forest Watch contributors, let’s start by monitoring land cover changes in the region to better pinpoint drivers of deforestation and formulate appropriate responses.       Between 2004 and 2011, BrazilRead More …

Terra-i: No stranger to controversy

5 February, 2014 by (comments)

Two things tend to happen when people get their hands on a new tool that is fundamentally helpful. First, they discover more uses for it than anyone could have imagined. And second, the more numerous and diverse the uses, the more likely it is that the tool will eventually become associated with conflict and controversy. A recent application ofRead More …

Terra-i snapshots #1: A quick tour of some deforestation hotspots… and at least one reason for optimism

8 May, 2013 by (comments)

Tucked away at the back of the one storey building that is CIAT’s Decision and Policy Analysis Research Area, is a door marked E0-30. Inside is a warren of offices, one of which is the Terra-i nerve centre. Here programmers and GIS experts use images from satellites hundreds of kilometres above Earth to track deforestation in Latin America inRead More …

Eye in the sky: Terra-i keeps track of deforestation

14 February, 2013 by (comments)

The recent launch of Terra-i, a near real-time deforestation monitoring system for Latin America, brings the hotspots of forest loss into sharp focus. Based on satellite information from NASA, Terra-i can zoom-in on the region’s forests to a resolution of 250m x 250m. It’s smart enough to distinguish between natural losses and those caused by human activity – andRead More …

Scientists develop first satellite deforestation tracker for whole of Latin America

19 June, 2012 by (comments)

An international team of researchers in Colombia, the UK, USA and Switzerland have developed the first ever system to monitor deforestation across Latin America in near real-time using satellite data. Preliminary results from the new system reveal that in parts of Colombia, deforestation has increased by 340 per cent since 2004; and over a million hectares of forest haveRead More …
