VD.70-Introduction to soil erosion - ( RUVIVAL ).

Soil erosion is broadly defined as the accelerated removal of topsoil from the land surface.

It is a process that has a strong impact on economy, society and environment: almost ¾ of the Earth’s lands are in fact being eroded.

Different approaches exist to counteract erosion. Remediation techniques are implemented on already affected sites, while preventing conservation measures aim to protect the soil before the erosive action takes place.
