Annual area exposed to drought (top) and impacted by drought (bottom) in the EU, in 2000-2024

The chart shows the annual area in km² affected by drought during the period 2000-2024, where vegetation productivity did not recover to the 2000-2020 baseline condition. The values are summed for the EU-27 region, by ecosystems types. Note: the reported figures refer to the thresholds and input data used. The reported absolute values may be different if different method and different data are used.

Note: The reported absolute values may be different if different method and different data are used. Here, drought exposure is defined as the area experiencing strong deficit in soil moisture compared to the 2000-2020 baseline. Strong deficit is defined as anomalies that are lower than -1 standard deviation from the baseline. Drought impact is defined as the area in km2 where vegetation productivity did not recover to the 2000-2020 baseline conditions due to drought. Non-recovery was defined as anomalies that are lower than -0.5 standard deviation from the baseline. See more under the supporting information section.

Methodology

Drought exposure is defined as the area experiencing strong deficit in soil moisture compared to the 2000-2020 baseline. Strong deficit is defined as anomalies that are lower than -1 standard deviation from the baseline. Drought impact is defined as the area in km² where vegetation productivity did not recover to the 2000-2020 baseline conditions due to drought. Non-recovery was defined as anomalies that are lower than -0.5 standard deviation from the baseline. The vegetation productivity is estimated using the Medium Resolution Vegetation Phenology and Productivity datasets of the Copernicus Land Monitoring Service.
