Monitoring meteorological drought impacts supports policy measures that target, among others, greenhouse gas removals and the adaptation of ecosystems to climate change. In 2022, Europe experienced its hottest summer and second warmest year on record, and consequently the largest overall drought impacted area: over 630,000km2 as opposed to the 167,000km2 annual average impacted area between 2000 and 2022. Between 2000 and 2022 there is an increasing trend in drought-impacted areas in the EU. Drought impacts may increase further if global mitigation and EU and national adaptation strategies are not effectively implemented.
The maps show the long-term average soil moisture contents (left) and the trends in soil moisture values (right), aggregated by NUTS3 regions. Soil moisture is equal to 0 when the soil is severely dry (wilting point) and equal to 1 when the soil moisture is above the field capacity. Low long-term average soil moisture values indicate areas where during the 2000-2019 period the soil moisture deficit was the biggest problem. Trends are expressed in standard deviation from the long term average. Negative trends indicate that soil moisture values show a decreasing tendency during the 2000-2019 period. Areas with lower soil moisture content together with decreasing tendency in the soil moisture are in risk of loosing their land functions of supplying ecosystem services.

Monitoring the pressure from soil moisture deficits can warn of potential impacts on plant development and soil health, supporting the assessment of drought-tolerant, resilient and vulnerable ecosystems. In 2000-2019, soil moisture in the growing season was several times below the long-term average in the EEA member countries plus the United Kingdom. The largest soil moisture deficits occurred in 2003, 2017 and 2019, affecting over 1.45 million km 2 in 2019. Soil moisture content was also low in 2012, 2015 and 2018, contributing to increasingly frequent and intense drought pressure.
The dataset consists of a collection of annual soil moisture (SM) anomalies during the vegetation growing season (GS) for the years 2000-2019 across EEA 38 area and the United Kingdom. The vegetation growing season is defined by EEA´s phenology data series "Vegetation growing season length 2000-2016" [https://www.eea.europa.eu/data-and-maps/data/annual-above-ground-vegetation-season]. The anomalies are calculated based on the European Commission's Joint Research Centre European Drought Observatory (EDO) Soil Moisture Index (SMI) with respect to the 1995–2019 base period. The yearly start and end of GS periods are dynamic and calculated according to the EEA Phenology Indicators. A positive anomaly indicates that the observed SM was wetter than the long-term SM average for the base period, while a negative anomaly indicates that the observed SM was drier than the reference value. Because SM anomalies are measured in units of standard deviation from the long-term SMI average, they can be used to compare annual deficits/surplus of SM between geographic regions. EDO is one of the early warning and monitoring systems of the Copernicus Emergency Management Service. As the dataset builds on EDO's SMI, it therefore contains modified Copernicus Emergency Management Service information (2019).
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.
Agriculture has multiple impacts on the environment, climate and human health. Unsustainable farming practices lead to pollution of soil, water, air and food and over-exploitation of natural resources.
Pollution changes a medium such as air, water or soil in a way that can make it harmful to people or nature. Different types of pollutants include chemicals, dust, noise and radiation. EEA Signals 2020 looks at pollution through different lenses related to the Agency’s work and EU legislation.
Monitoring soil moisture shortages is a precondition for managing drought adaptation and resilience of ecosystems, such as foreseen by the EU Nature restoration plan of the EU Biodiversity strategy 2030. This dashboard analyses 20 years (2000-2019) soil moisture content in Europe (EU27, EEA-38 and the UK). Soil moisture deficits, trends in soil moisture values and the area under pressure are presented by countries and land cover. Scroll down to the More information section for further details.
Yearly vegetation productivity during 2000-2016 are analyzed in areas under drought pressure, measured as precipitation shortages and low soil moisture content. Vegetation productivity values are disaggregated and detailed by year and by detailed land cover categories. Strong negative values indicate strong drought intensity, with vegetation productivity values lower than the long term average normal condition. Scroll down to the More information section for further details.
The map shows the percentage of the average annual change in soil sealing for each of the rectangular 10 km x 10 km grid cells, over the 2006-2015 period
The map shows the density of soil sealing in 2012, based on a 10 km2 reference grid. Green and light orange colors show areas with no or very limited sealing, while red and dark red colors show highly to fully sealed grid cells (mainly urban areas).
For the reference year 2015 , 85 861 km 2 of the total area covered by the EEA-39 countries were mapped and categorised as 'sealed surface' in the Copernicus imperviousness product. This corresponds to 1.466 % of the total EEA-39 area. Between 2006 and 2015, soil sealing (imperviousness) in all EEA-39 countries increased by a total of 3 859 km2 , an annual average increase of 429 km 2 . During this period, the average annual increase in soil sealing relative to country area varied from 0 % to 0.088 %. In 2015, the percentage of a countries' total area that was sealed also varied greatly, with values ranging from 16.17 % (Malta) to 0.07 % (Iceland). The highest sealing values, as a percentage of country area, occurred in small countries with high population densities, while the lowest sealing values can be found in large countries with low population densities. The average annual increase in sealing was 460 km 2 between 2006-2009, increasing to 492 km 2 for the 2009-2012 period and slowing to 334 km 2 for the 2012-2015 period. The slow-down in the sealing increase between the two reference periods occurred in 31 out of 39 countries. The same trend is visible for sealing figures normalised by the size of the country (the % of the country newly sealed on average annually for the three periods). The most problematic situation occurs in countries where there is already a high percentage of sealing and where the annual rate of increase relative to country area is high. Even more problematic are situations where, for 2012-2015, the rate of sealing increase is accelerating, in contrast to the general trend of a slowing rate of increase.
The chart shows the effect of frost frequency variations on vegetation productivity, expressed in standard deviation units of vegetation productivity.
The chart shows the effect of precipitation variations on vegetation productivity, expressed in standard deviation units of 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.
