Find out its causes and effects, but most importantly the solutions to control and prevent land pollution, and how you can contribute to reduce it.
Land pollution is a heavy topic. With its direct impact on the environment and consequently on the health of humans, animals, and plants, soil pollution is a real problem that involves both political powers and citizens.
Soil is not a renewable resource.
Its degradation can be rapid (a few years or decades) while it takes several thousands of years to form and regenerate.
What causes land pollution, what are its effects and what are the possible solutions to prevent it?

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.
There are different types of land pollution:
Human activities are the main causes of land pollution:
Agricultural activities are 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.
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.
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.
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.
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.
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.
Is land degradation only resulting from human activities?
Natural disasters, such as drought, floods and volcanic eruptions, or technological events - like radioactive fallout following a nuclear test - also produce soil degradation.
Soil pollution can harm public health and animals, as well as the quality of groundwater and surface water. Its effects are of several kinds, namely deferred or immediate, but also direct or indirect.
On the environment
Contamination of groundwater, loss of topsoil, water nutrient enrichment and increased risk of wildfires (because of the dry conditions created by the pollutants in the soil) are among the consequences of land pollution.
As land pollution and soil erosion progress, animals are forced to shift habitats and adapt to new conditions. As a result, some species are at risk of extinction.
On human health
The potential effects of soil contamination on human health include breathing disorders, birth defects, skin diseases, and cancer.
How to solve land pollution? Here’s a list of soil pollution solutions:
Environmental remediation consists of removing pollution from the soil, groundwater or surface water. Bioremediation (microbes) and phytoremediation (plants) can be used to convert the pollutants into harmless products. These are natural solutions that need to be supported by in-depth actions.
2. Green agriculture
Sustainable agriculture is essential as it is meant to control the impact on the cultivated environment, by minimizing the external contributions (phytosanitary products), by diversifying the cultures and by using biological treatments.
3. Sustainable forest management
Conservation of the forests is key. Without the protection of the trees, the land becomes dry and starts to erode. Therefore, sustainable forestry or logging is crucial to saving the soil from pollution.
4. Proper waste disposal
Be it for industrial or household waste, efficient waste disposal is one of the most effective ways of curbing land pollution. This especially applies to toxic and hazardous waste disposal.
5. The "3 R's" Rule & Education
Reducing the use of non-biodegradable products will lower plastic pollution and eventually have an impact on land pollution. This is why it is very important to reuse and recycle every possible item. Education should also play a major role in efforts to protect the environment from land pollution.
