Pakistan floods: Satellite images and maps show scale of disaster

·2-min read

The little boy in blue could be around nine or 10 years old. He's sat with his family on rescued furniture and they are surrounded by floodwaters.

He lives in Mehar, one of the areas in Pakistan worst hit by the monsoon floods which have submerged a third of the country.

This slider shows you what the boy's home district looked like on 29 August compared to the same time a month ago.

Fields surrounding the central urban area have disappeared under dark green water. Only the centre of Mehar, roads leading to it and some small parts of the landscape can still be seen.

Behind the little boy and his younger siblings, you can see a makeshift shelter made of mismatched sheets of plastic inside the damaged walls of buildings.

It's a sight familiar across the country.

More than 317,000 houses have been destroyed and another 734,000 partially damaged, according to the Internal Displacement Monitoring Centre.

The little boy lives in the Sindh province which has suffered some of the worst damage, according to this map made by the UN and published on 26 August.

The boy in blue and his family are from an area with a population of about 460,000 people, according to the 2017 census. Mehar is part of the Dadu district, which is home to more than 1.6 million people and has been widely impacted by the floods.

In this before and after image, which shows Mehar and the city of Dadu, swathes of blue and green water can be seen flooding the Dadu district.

It is not only the Dadu district that is being overwhelmed with floodwater.

Across the country, more than 33 million people, about 15% of the population, have been affected by the flooding. More than 1,000 have died.

The red dots on this map from NASA Worldview, a satellite imagery interface, indicate where evidence of flooding over a two- or three-day period has been recorded. Issues such as cloud coverage can affect the number of dots on the map.

Satellite images also show heavy flooding in Gandakha to the east of the country.

As well as in Mianwali, in the north east.

Pakistan's prime minister has said the devastating floods are "probably the worst in the country's history".

The destruction has prompted the UN to appeal for $160m (£136m) in emergency funding to help the nation.
