Millions are suffering terribly in this flood 'mega-disaster' ...it's the worst I've ever seen

The Pakistan flood is the worst emergency I've ever seen. It's bigger than both the Haiti and the 2005 Pakistan earthquakes put together.

Much of the Pakistani population now has nowhere to go -- millions of homes that were made out of mud and straw have been washed away.

We estimate that around 80pc of houses in Charsadda -- one of the country's worst hit areas -- have been destroyed.

The harsh reality facing Pakistan is that all of its crops of wheat and tobacco have been destroyed and all of the seed that was for planting this October has been wiped away.

Receded

That leaves a dangerously low supply of food for the future.

If aid workers and the country's people don't rehabilitate and work on the land and get new seed, there won't be any crops and it'll leave millions without jobs and without food.

Yesterday I visited Charsadda, where the waters have receded, and you can see where the waters had reached on the buildings, up to levels over 10 feet high.

All of the houses are full of mud and a lack of equipment, such as tractors and trucks, leaves people with no option but to remove the debris with their hands.

One village I visited had to move to higher ground to escape the flooding, and the only higher ground was their local graveyard.

Eventually the flood even attacked that, and its power was so strong that bodies were removed from the graves.

Ferocious

It's just incredible how ferocious the flood waters are and they're now wreaking havoc in the south of the country.

There are now villages being cut off by the floods and they're so remote that people have no shelter or blankets for when it gets cold.

There are hundreds of thousands of people who are living under the threat of not having enough food or water.

We've seen children with scabies on their hands and feet, and with eye infections.

And while we're distributing food items, our major concern is hygiene so that people don't contract malaria or water- borne diseases.

We are giving out hygiene kits, plastic sheeting, blankets, and cooking utensils.

I'm now in a southern city called Sukkar, which hasn't yet been affected, and thousands of people are just finding any place possible where they can put their tents up.

But the Pakistani people seem to be very united, even though they have nothing.

Generous

They're still giving what they can and buying blankets, and giving them to others when they only have two for themselves.

They're getting their food rations and giving half to their neighbour. Even though they have so little, they're being so generous.

The money people donate to Concern is getting to the beneficiaries.

It is going to Pakistan and its people, and we're battling against time to avoid a potential nightmare scenario developing on your behalf.

Concern is targeting 500,000 people with supplies including food, clean water, and other basic necessities, as well as setting up mobile medical clinics to treat and prevent the spread of disease.

The Pakistan flood has been so devastating that it's being called a mega-disaster.

I have found the Pakistani people extremely friendly and welcoming, and they go out of their way to help people around them, but they're living on a precipice.
