causes and consequences of soil
erosion and desertification -
removal of vegetation, overgrazing,
overcultivation, clearance of slopes,
poor irrigation; food shortage and
water shortage, displacement of
people
--- End quote ---
How is water shortage a consequence of Soil Erosion?
Also, why would it cause the displancement of people?
Fastal:
since the soil is gone, people cant farm anymore, they have to migrate
water shortage because since there are no trees, there is less evapotranspiration, so less rainfall, resulting in water shortage. all the water that does come down is lost as trees are no longer there to store it.
Aayesha:
thanks Keyur and Fatsal :)
