Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide.

Why does soil erosion occur?

Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.

When did soil erosion start?

A Dirty Truth: Humans Began Accelerating Soil Erosion 4,000 Years Ago. Recent research combining analysis of carbon dating, sediment accumulation rates, and pollen records from 632 lake beds worldwide finds deforestation tied to increased soil erosion.
