The maps shows the time series of yearly vegetation productivity anomalies under drought impact aggregated by NUTS3 regions. Negative anomalies indicate vegetation productivity conditions which are lower than the long term average normal condition. The time series spans over 2000-2016 and individual years can be explored be choosing the year of interest in the drop-down filter.

More 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.

Indicator Assessment Drought impact on ecosystems in Europe Monitoring  vegetation response to water deficit due to droughts is necessary to be able to introduce effective measures to increase the resilience of ecosystems in line with the EU’s nature restoration plan — a key element of the EU biodiversity strategy for 2030. Between 2000 and 2016, Europe was affected by severe droughts, causing average yearly vegetation productivity losses covering around 121 000 km 2 . This was particularly notable in 2003, when drought affected most parts of Europe, covering an estimated 330 000 km 2  of forests, non-irrigated arable land and pastures. Drought impact was also relatively severe in 2005 and 2012.
Indicator Assessment Vegetation productivity Vegetation productivity indicates the spatial distribution and change of the vegetation cover - a key characteristic of ecosystem condition.  Vegetation productivity in Europe on average has a regional pattern of increase and decline. Increase was observed most in South Eastern Europe, over croplands and wetlands in the Steppic region and grasslands and sparsely vegetated lands and in the Black Sea and Anatolian regions. Decline happened most over croplands and grasslands in the Atlantic region as well as over wetlands in the Alpine region. Climate has important influence on vegetation productivity in Europe. Strongest driver is precipitation, especially in the South Eastern regions. Decreasing number of frost days increased productivity in the Pannonian region but decreased productivity in the Atlantic region. Climatic variations are important drivers of vegetation productivity, but land use changes are even stronger. Productivity was most increased by agricultural land management and converting other lands to agriculture, whereas largest decrease was caused by sprawling urban areas.
