Mass urbanisation is a phenomenon that is occurring with increasing frequency around the world.
The construction of buildings and roads in rural or natural areas has a major impact on the environment, and one of the most important aspects is the effect on soil health.
Urbanisation involves the destruction of natural vegetation cover, as trees are felled and grasses and shrubs are cleared to make way for construction. Vegetation is essential for maintaining soil moisture and fertility, and its loss can have serious consequences for the ecosystem. In addition, urbanisation can also lead to soil erosion due to the removal of roots and exposure to wind and rain.
Another problem related to urbanisation is soil compaction. The construction of buildings and roads involves the removal of topsoil and the compaction of lower layers. This can hinder the infiltration of water into the soil, which can lead to drainage and erosion problems. In addition, soil compaction can also negatively affect soil microbial life, which can affect soil fertility.
Urbanisation can also have a negative impact on biodiversity, as natural habitats are eliminated and remaining green areas are fragmented. This can make it difficult for many plant and animal species to survive, and can also negatively affect soil health.
Urbanisation in Europe has experienced a large increase in the last ten decades. According to Eurostat data, the percentage of the population living in urban areas in Europe increased from 72% in 1990 to 79% in 2019. This has led to increased pressure on land, as more land is required for housing, infrastructure and services.
In Europe, the main consequences of urbanisation on soil health are soil quality degradation, biodiversity loss, ecosystem degradation, loss of soil function and soil erosion. Many European cities have seen large tracts of rural land lost to urban sprawl, leading to significant loss of biodiversity and degradation of natural ecosystems.
In addition, urbanisation has led to increased soil sealing, which has hindered water infiltration into the soil and increased soil erosion. The construction of buildings and roads has also compacted the soil, making it difficult for plants to grow and negatively affecting soil microbial life.
In recent years, soil conservation has become increasingly important and measures have been implemented to mitigate the negative effects of urbanisation on soil health. Many European cities have adopted sustainable and environmentally friendly approaches to urban planning, and work has been done to minimise the negative effects of urbanisation on soil. However, much remains to be done to ensure that urbanisation in Europe is sustainable and environmentally sound.
In conclusion, massive urbanisation has a major impact on soil health, and it is important to consider these negative effects when planning and developing urbanisation projects. It is necessary to promote a sustainable and environmentally friendly approach and work to minimise the negative effects of urbanisation on the soil. Through education and awareness-raising, we hope to promote more sustainable urban development that preserves the health of the soil and the environment in general.
