Impacts: Alteration to geographical landscapes: Desertification


Desertification is the land degradation in drylands. It's caused mainly by human impacts, causing deterioration to the quality of soil and water sources, causing drastic fall to soil fertility. The final product is desert, making the place almost uninhabitable.

Causes
  • Clearance of forests (deforestation), making the soil exposed to erosions
  • Drought
  • Climate change (to warmer condition), leading to high severity of drought
  • Poor resource management in drylands
Impacts
  • Infertility of soil
  • Degradation of nutrient content of the soil
  • Hunger and higher vulnerability of diseases
  • Economic and social downturn
  • Lost of biodiversity
  • Effects to climate change (no trees to process photosynthesis)
  • Ultimate low rate of rainfall
