Causes of Drought:

Here are the causes of drought and desertification:

• Causes of Drought:

  • Natural climate variability: Long-term shifts in atmospheric circulation patterns, such as those influenced by phenomena like El Niño, can lead to reduced rainfall in certain regions.
  • Reduced precipitation: A sustained period of lower-than-average rainfall is the direct cause.
  • Increased temperatures: Higher temperatures lead to increased evaporation from land and water bodies, exacerbating water shortages even with normal rainfall.

• Causes of Desertification:

  • Overgrazing: Too many livestock consume vegetation faster than it can regrow, leaving soil exposed and vulnerable to erosion.
  • Deforestation: The removal of trees, which help anchor soil and retain moisture, exposes the land to wind and water erosion.
  • Unsustainable farming practices: Intensive cultivation, monocropping, and improper irrigation can deplete soil nutrients, degrade soil structure, and lead to salinization.
  • Climate change: Rising global temperatures and altered rainfall patterns intensify droughts, making drylands more susceptible to degradation.
  • Water mismanagement: Inefficient use of water resources, such as over-extraction of groundwater, can deplete water tables and stress ecosystems.
