Why did Karachi sink in the rain?

  • As per the Meteorological Department’s near accurate prediction, Karachi experienced torrential rain this month.
  • In the recent past, Karachi has seen intense densification in existing neighbourhoods due to the street commercialisation policy enforced by the erstwhile City District Government since 2002.
  • Spot densification alters the rain and sewage water flow gradients.
