Soil damage
A soil damage or harmful soil change is for humans a material adverse or dangerous impairment of soil functions. “Harmful soil changes” within the meaning of Section 2 (3) of the Federal Soil Protection Act (BBodSchG) are impairments of soil functions that are likely to cause dangers, significant disadvantages or significant nuisances for individuals or the general public.
In 1999, the soil was declared a third protected asset alongside water and air. In addition to the BBodSchG, guidelines, guidelines, forest construction principles, certification systems, etc.
Examples of possible soil damage
Soil damage can have various reasons and manifestations.
On the one hand there are natural processes of long-term soil development, which include many factors of soil degradation. Soils are always in contact with their environment and are therefore constantly developing. But this process is a constant, natural change. Soil damage in the true sense of the word only occurs when these processes increase sharply through human intervention.
On the other hand, a lot of soil damage is caused by artificial, purely human processes that do not occur in nature.
naturally occurring processes
process | description | Examples of human risk factors that speed up the process |
---|---|---|
Leaching or leaching | Dissolving and flushing out salts
Nutrient loss |
too much watering
Arable land without vegetation (more seepage water) Forest clearance (especially in the tropics) |
Soil erosion | Movement of soil by wind or water |
Overuse and overgrazing (destruction of the vegetation cover)
Agriculture on slopes Arable land without vegetation |
Salinization of the soil | Accumulation of salt in the soil | Agriculture with irrigation in arid / semi-arid zones
Irrigation management not adapted |
Soil acidification | Drop in pH
(natural process in humid zones) Depletion of buffer systems |
Use of acidic fertilizers
Lack of liming |
Desertification | devastation | Overuse / overgrazing
excessive water abstraction from rivers / lakes / groundwater Cultivation of water-intensive crops |
artificial processes
process | description | Example (s) |
---|---|---|
Soil compaction | Change of soil structure to denser storage | Driving on with heavy machinery
Leveling terrain |
Active nutrient extraction | Excessive removal of nutrients
Long-term destruction of the soil |
Plague extraction
Complete removal of all harvest residues |
Earthworks | Breaks / structural damage
Disturbance of the soil biotope |
All major earth movements |
Contamination | Introduction of harmful substances
(Heavy metals, chemicals etc.) |
Use of fertilizers
wild garbage dumps / garbage disposal Spreading of sewage sludge Military contaminated sites |
Surface sealing | Sealing the surface of the earth
Extensive destruction of all natural soil functions |
Buildings such as settlements, industry
Infrastructure like roads or airports |
acid rain | Artificial soil acidification through polluted rainwater
Loss of nutrients and buffer |
Immissions |
Requirements for environmental liability in the event of soil damage
The prerequisites for soil damage, which can be relevant for environmental liability and official intervention in accordance with the Federal Soil Protection Act, include: Introduction of substances etc. on, in or under the soil, thereby impairing soil functions according to Section 2 (2) BBodSchG and causing a risk to human health.
In order to counteract damage to the soil, the functional, regenerative and sustainable usability of the soil must be preserved over the long term.
