While the overall patterns of erosion are generally sound, the validation of erosion data can be challenging. The data presented are currently being validated through comparisons with national datasets and expert judgement. In this sense, zooming in on a specific locality can give the impression of a situation that differs from reality. In addition, the model used in this exercise does not consider localised intense precipitation.
(upper) Areas affected by three recurrent negative precipitation anomalies (as indicated in the graph: 2000, 2003 and 2006 during the period 1999–2010 based on the standardised precipitation index, a statistical correlation to recurrent anomalies through principal component analysis (PCA) of time series climatic data). The prevalence of recurrent negative precipitation anomalies in the Mediterranean area is very apparent. Such anomalies can also affect areas with traditionally humid climates.
(lower) The effect of these events on ecosystem productivity based on a change index: the steadiness index. This index addresses both the long-term trend and the net change of primary production calculated from satellite time series over the period in which the recurrent negative precipitation anomalies occurred (1999–2010). The areas in red denote regions with a stronger likelihood of decreased productivity relative to the ecosystem capacity.
SMOS provides a global image of surface soil moisture every three days; this map covers the period 8–15 June 2010. Yellow colours indicate drier soil surfaces; blue colours denote wetter conditions. SMOS can measure soil moisture levels to an
accuracy of 4 % at a spatial resolution of 50 km — about the same as detecting a teaspoonful of water mixed into a handful of dry soil.
Global scheme of nitrogen cycle, showing major nitrogen reservoirs (atmosphere, soil and living organisms), major processes (nitrification, denitrification, nitrogen fixation, assimilation etc.) and actors (plants, animals, bacteria, human beings).
Raster data set of built-up and non built-up areas including continuous degree of soil sealing ranging from 0 - 100% in aggregated spatial resolution (100 x 100 m).
Soil contamination requiring clean up is present at approximately 250000 sites in the EEA member countries, according to recent estimates. And this number is expected to grow. Potentially polluting activities are estimated to have occurred at nearly 3 million sites (including the 250000 sites already mentioned) and investigation is needed to establish whether remediation is required. If current investigation trends continue, the number of sites needing remediation will increase by 50% by 2025. By contrast, more than 80000 sites have been cleaned up in the last 30 years in the countries where data on remediation is available. Although the range of polluting activities (and their relative importance as localised sources of soil contamination) may vary considerably across Europe, industrial and commercial activities as well as the treatment and disposal of waste are reported to be the most important sources. National reports indicate that heavy metals and mineral oil are the most frequent soil contaminants at investigated sites, while mineral oil and chlorinated hydrocarbons are the most frequent contaminants found in groundwater. A considerable share of remediation expenditure, about 35% on average, comes from public budgets. Although considerable efforts have been made already, it will take decades to clean up a legacy of contamination.

The CORINE Land Quality project (Version 1990) is an assessment of land quality in southern Europe based on four factors: soil, climate, slopes, land improvements.
