Vegetation productivity time-series under drought impact by detailed land cover and countries (2000-2016, EEA-39)

Vegetation productivity loss due to drought impacts and the extent of impacted areas are presented. Vegetation productivity loss is indicated by standardized anomalies of yearly vegetation productivity during 2000-2016, and are analyzed in areas with statistically significant drought pressure, measured as precipitation shortages and low soil moisture content. Anomalies are disaggregated and detailed by year, by country and major land cover categories. Negative anomalies indicate vegetation productivity conditions which are lower than the long term average normal condition. The extent of the impacted area is measured in km2.

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.
