NEWS: [ECOBASE SOIL FACT] What is Soil Degradation?
Soil degradation is the decline in soil quality caused by various factors, reducing its ability to support plant life and perform essential ecosystem functions. This process can result from natural events or human activities and can have significant environmental, economic, and social impacts.
Causes of Soil Degradation
- Erosion: The removal of the topsoil layer by wind, water, or human activity. This layer is rich in nutrients and organic matter, essential for plant growth.
- Deforestation: Clearing forests for agriculture or urban development reduces the amount of organic matter returned to the soil and disrupts the soil structure.
- Overgrazing: Excessive grazing by livestock can lead to soil compaction, reduced vegetation cover, and increased erosion.
- Agricultural Practices: Intensive farming, monocropping, and the excessive use of chemical fertilizers and pesticides can deplete soil nutrients and harm soil organisms.
- Urbanization: Construction and development activities can lead to soil sealing, where the soil surface is covered by impermeable materials, reducing its ability to absorb water and support plant life.
- Climate Change: Changes in temperature and precipitation patterns can affect soil moisture levels and increase the risk of erosion and desertification.
