Millions of people are homeless, roads are destroyed and tens of thousands of schools and hospitals are in ruins months after the floods.
At the COP 27 summit, the country's Prime Minister Shehbaz Sharif called on Western nations to offer compensation to poorer, vulnerable countries.
The figure for losses and rebuilding is more than $30 billion.
More than 1,700 people were killed in the floods and two million homes were damaged. People who survive are living in uncertainty and despair.
Hanifa explained what happened on the day in August when the rains changed everything as she took shade under a tent.
She says that her son's death saved her and her family.
Abdul was worried that the mud brick house in the south-western province of Balochistan was going to collapse as the water hit it.
He was going to take his family to a mosque to stay out of harms way.
Abdul returned to get something before they left. Hanifa says that he didn't come back. He was buried at the mosque.
Her other son used his money to hire a car so they could escape the flooding.
Hours before the bridge collapsed they crossed it. She says that some of Hanifa's relatives got stuck on the other side of the river and were swept away.
We've seen floods before but never like this one. Many villages were destroyed when homes collapsed.
Weak, not just from the weight of grief, but also from hunger, she was in a relief camp when she was interviewed by the British Broadcasting Corporation.
Hanifa mourns the loss of her son, Abdul.
He's always in my thoughts.
With her school underwater, she doesn't think she'll ever become a doctor.
She says she misses her teachers.
She has been unable to study since her books were washed away.
She was forced to stay in a tent far from her village because her home was claimed by the floods.
With her days devoid of purpose, she now spends most of her time sitting, apart from when she prays or helps wash dishes at the camp.
It's left Najma afraid.
My education has been wasted. She wants to finish her secondary education.
Going to school as a girl was already a difficult task. Many families don't allow their daughters to go to school.
It could take a long time for the home and school to be renovated. Some charities and aid agencies have set up temporary learning centers because of the damage done to schools.
Lessons are only available for the youngest at the camp where she is staying.
As she sits in her tent, she can hear a group of children chanting the alphabet in front of her. She wants to return to her class.
I want to open a hospital for people who can't afford medical care.
"If they want anything, we will give it to them."
There are piles of bricks, slabs of concrete, mounds of rubble, and a bright green door that leads to nothing.
Abdul Qayoom told me that the home was in his family for a century.
"My three-year-old daughter keeps asking me when we can move back into her bedroom," he says, gesturing to the space where it used to stand.
He lost his house in the Hana Urak area of Pakistan because of the flash floods at the end of August.
"My uncle is 84 years old and he hasn't seen this kind of flooding before," Abdul says.
Abdul and his family are staying with his brother. One thing he is certain of is that when he rebuilds his home, it won't be here.
I will not rebuild in the same place, I think we will look for a safer place higher up on a hill.
The area surrounding Abdul's home is in a state of disrepair.
Huge chunks are missing from roads and rubble is scattered everywhere in this district, famous for its apples.
Most of the people in this area are poor and have lost their homes and sources of income.
The local said as we left. He says that you either own a house or a grave.
You always come back home when you go to the market. You always want to come home when you travel to Mecca. He said that home is everything.
The home he left has now been turned into nothing.
