Counting trees to save the woods: using big data to map deforestation

October 2, 2014

Forests provide benefits few of us appreciate. They store carbon and mitigate the impacts of climate change, preserve biodiversity and ecosystem stability. They provide resources we all use, and more than a billion people around the world depend on forests directly for their livelihoods. But forests are under more pressure today than ever. Between 2000 and 2012, the world lost a net 1.5 million square kilometres of tree cover, an area roughly the size of Mongolia. The clearing and burning of forests is responsible for between 12-20% of greenhouse gas emissions.
