Heavy monsoon rains continue to devastate Pakistan. Swollen rivers have toppled bridges, decimated crops, and forced hundreds of thousands of people from their homes. The United Nations has appealed for $460 million US to support humanitarian aid efforts. Here is a by-the-numbers look at the effects of the flooding and the bid to bring relief.

Flooding loss and damages

14.5 million: People affected by the flooding, according to the National and Provincial Disaster Management Authorities.

3.5 million: Children at high risk of deadly waterborne disease.

200,000: Number of livestock lost.

160,000 square kilometres: Area of land in Pakistan affected by the flooding, according to the United Nations, which also notes that this area is the equivalent of Austria, Belgium and Switzerland combined.

9,000 millimetres: Amount of rain that fell in Khyber Pakhtunkhwa province over the course of one week in late July, according to the Pakistan Meteorological Department. The UN notes this is ten times the amount of rain the region typically receives in one year.
