Arresting Soil Erosion - Visualizing Its Causes, Effects and Conservation

SOIL EROSION

  • Naturally occurring process that affects all landforms.
  • It is the washing or blowing away (by water or wind) of the top layer of soil.

Soil Erosion

Rain and Cloud for Soil Erosion

  • Impact of raindrops on the soil surface can break down soil aggregates and disperse the aggregate material.

Wind for Soil Erosion

  • It is a serious environmental problem.
  • Attracting the attention of many across the globe.
  • Occurring mostly in:
    • Flat, bare areas
    • Dry, sandy soils
    • or anywhere the soil is loose, dry, and finely granulated

Effects of Soil Erosion

  • Effects of soil erosion can be felt on-site, meaning at the site of soil disruption. So, soil quality is reduced.
  • Crops are damaged due to sand storms.

SOIL CONSERVATION

  • It is the prevention of soil loss from erosion or reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination.
Soil Conservation

AFFORESTATION

  • It is the establishment of forest or stand of trees in an area where there was no previous tree cover.
  • It is the process of planting large numbers of trees on land.
  • It is necessary to combat the issues of:
    • Global warming
    • Soil erosion
    • Pollution
  • Maintenance of biodiversity and ecological balances.
