Which is not the cause of watershed deterioration?

  • A.Unscientific mining and quarrying
  • B.Faulty road alignment and construction
  • C.Apathy of the people
  • D.Poor water yield in terms of quantity and quality

Answer: D

Poor water yield in terms of quantity and quality is not a cause of watershed deterioration.

Poor water yield is a result of a degraded watershed: when the catchment is damaged, rain runs off quickly, springs dry up and the water carries silt.

Unscientific mining and quarrying, faulty road alignment and construction, which cause erosion and landslides, and the apathy of the people towards conservation are all causes of watershed deterioration.
