What you should know about this indicator

  • Wildfires are detected through the use of satellite imagery obtained from MODIS (Moderate Resolution Imaging Spectroradiometer) and VIIRS (Visible Infrared Imaging Radiometer Suite). These satellite systems are capable of identifying thermal anomalies and alterations in landscape patterns, which are indicative of burning.
  • The data provider is presently engaged in a global accuracy assessment and acknowledged that they might be underestimating the genuine impact of wildfires, primarily due to constraints imposed by the spatial resolution of the sensors they employ.
Weekly share of the total land area burnt by wildfires
The total area consumed by is recorded for each fire event, even if fires occur in the same location multiple times. The 2024 data is incomplete and was last updated 24 November 2024.

Sources and processing

This data is based on the following sources

The dataset provides a weekly comprehensive overview of fire activity and its environmental impact, incorporating data from the Global Wildfire Information System (GWIS) and satellite imagery from MODIS and VIIRS. It includes metrics such as the area of land burnt, cumulative burnt areas, carbon dioxide emissions from fires, cumulative carbon emissions, the number of fires, and cumulative fire counts.

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.

Notes on our processing step for this indicator

The share of the total land area burnt by wildfires is calculated by dividing the area burnt by wildfires by the total land area of the country.
