More of Africa scarred by fires than thought
04 February 2019
Wildfires can cause devastation and are also to blame for more than a quarter of greenhouse gases being released into the atmosphere. Satellites play a key role in mapping landscape scarred by fire – but the Copernicus Sentinel-2 mission has revealed that there are more fires than previously thought.
From the vantage of space, satellites can be used to detect fires and monitor how they spread and, in the first instance, this can often help relief efforts. However, satellites are also important for mapping the scars that fires leave in their wake, particularly in remote regions.
