Fires in Amazonia have made headlines around the world, but there’s more to the story. Analysis by Conservation International is revealing where the fires are and why that matters.

A tipping point
Protected areas and indigenous lands can help us save this vital ecosystem. Up to 15% of the Amazon has already been lost, and researchers suggest that if this reaches 25% to 30%, the entire biome will be permanently altered, with global ramifications for our climate.
Where there's smoke, there's Firecast
Developed in part by Conservation International, Firecast is an online platform that uses satellite observations to track ecosystem disturbances such as fires, fire risk conditions, deforestation and delivers this time-sensitive information to decision-makers through email alerts, maps and reports.
- The Amazon forest-agriculture frontier represents an approximately 1 km buffer that straddles the boundary of large contiguous forests and agricultural lands. This is a critical zone where tropical forests are dying back due to degradation and drying-out. It is also an area that contains an incredibly high concentration of fires.
- Due to uncertainties of the exact locations of the satellite-detected fires, we use a 1-km buffer to confidently separate fires inside protected areas and IP areas from fires that that occur within 50 meters of the boundary edge, either inside or outside. We refer to this edge zone as the “Protected Area and IPLC accuracy buffer.” Read an explanation of fire detection accuracies.
- Brazil's Legal Amazon (or Amazônia Legal) is the largest socio-geographic division in Brazil, containing all nine states in the Amazon basin. It is an official designation covering 59% of Brazil but only 12.34% of the Brazilian population lives there. Although called Amazônia Legal, the region overlaps three different biomes: all of Brazil's Amazon biome, 37% of the Cerrado biome and 40% of the Pantanal biome.
