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).
The map shows:
LEFT: Distribution of landslides with human consequences from AD 1300 to 2002. The size of the triangle indicates the intensity of the event.
RIGHT: Landslide susceptibility map of Italy.
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.
