WHAT IS SOIL/LAND POLLUTION?

Soil Pollution: A Hidden Reality - World | ReliefWeb
Land pollution refers to all forms of pollution affecting any type of soil: agricultural, forestry, urban, etc. Soil pollution is a disruptive element for many biological resources and ecosystems. A soil is polluted when it contains an abnormal concentration of chemical compounds potentially dangerous to human health, plants or animals.


WHAT ARE THE CAUSES OF SOIL/LAND 
POLLUTION?

1) Agricultural activities

It is one of the major sources of land pollution. The spreading of plant protection products such as pesticides and herbicides, as well as the emissions of livestock buildings and farms are at the origin of soil pollution, in particular by nitrogen and phosphates.

2) Deforestation

Because of deforestation and forest fires, soils lose their vegetation cover. The erosion process is thus accelerated, creating soil degradation as well as water pollution. Deforestation leads to the loss of the land’s value as, once converted into a dry or barren land, it can never be made fertile again.

3) Urbanization

Urbanization is another source of land degradation. The artificialisation of soils can cause a rapid and consequent carbon depletion, which contributes to climate change. Besides, it fragments natural habitats, ecosystems and landscapes, affecting biodiversity.

4) Mining

Mining waste is usually left behind in the form of spoil tips. These pit heaps can contain a wide variety of toxic substances that then seep into the ground as a result of rain. This can have a big impact on the regeneration of the vegetation.

5) Industrial waste

Industrial waste
Heavy industry often produces quantities of undesirable chemicals. If cleaning agents such as detergents are released irresponsibly, they can cause significant pollution on the ground. Storage tanks can also be a major source of land pollution in case of leakage.

6) Waste disposal

We produce large quantities of household waste every year, many of which could and should be recycled or degrade naturally. Much of our waste is either incinerated, causing potential air pollution issues or buried in landfills, causing soil pollution problems.
