What you should know about this indicator

Wildfires are detected through the use of satellite imagery based on the NASA MCD64 MODIS product which offers global assessments of burned areas and fire occurrences. Although widely used, this product is known to consistently underestimate both the extent of burned areas and the frequency of fires. However, in terms of historical trends, it stands out as the most comprehensive dataset, offering the longest time series compared to other available options.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.
