The map shows the long-term impact of water deficit on vegetation productivity, and the area of low vegetation productivity under water deficit impact, aggregated by NUTS3 regions. Negative anomalies are expressed in standard deviation and indicate vegetation productivity conditions that are lower than the long-term average under normal, non-drought conditions.

Additional information

Standardized anomalies of yearly vegetation productivity during 2000-2016 are analyzed in areas with statistically significant drought pressure measured as precipitation shortages and low soil moisture content.

Anomalies are expressed in standard deviations compared to the long term average vegetation productivity conditions for each 500m grid cell in the EEA39 region. Negative vegetation productivity anomalies indicate vegetation productivity conditions that are less than the long term normal condition.

The extent of the impacted area is calculated from the sum of those grid cells where the vegetation productivity anomaly was below -1 standard deviation in the given year.

In order to exclude low vegetation anomaly signals in the time series, only those grid cells were considered in this analysis where the Corine Land Cover (CLC) 2000-2018 series indicated no land use change between 2000-2018.
