Annual area burnt by wildfires by region

GWIS

What you should know about this indicator

  • Burned areas are detected from satellite imagery. NASA's MODIS satellite sensors scan the entire Earth's surface every one to two days, and the burned area product identifies land that shows the characteristic spectral signature of recent fire.
  • Each area of land is assigned to a land cover type — such as forest, savanna, or cropland — based on annual satellite-derived land cover maps.
  • Satellite detection of burned areas is known to underestimate the true extent of fire. Small fires and fires obscured by cloud cover or tree canopy are often missed. Despite this, the dataset provides the longest consistent global record available, making it well suited for tracking long-term trends.

Sources and processing

This data is based on the following sources

Global Wildfire Information System – Global Yearly Burned Area by Land Cover Type

Yearly burned area in hectares by land cover class (2002–2024) for all countries.

Data is fetched via the GWIS country profile API (cprof.effis.emergency.copernicus.eu). Note: the API contains more recent data than the bulk download ZIP on the downloads page, which currently has all-zero values for 2024.

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.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.
