The United Nations and Pakistan have issued an appeal for 160 million dollars (£136 million) in emergency funding to help millions of people affected by record-breaking floods that have killed more than 1,160 people since mid-June.
UN secretary-general Antonio Guterres said Pakistan’s flooding, caused by weeks of unprecedented monsoon rains, were a signal to the world to step up action against climate change.
“Let’s stop sleepwalking toward the destruction of our planet by climate change,” he said in a video message to an Islamabad ceremony launching the funding appeal.
“Today, it’s Pakistan. Tomorrow, it could be your country.”
More than one million homes have been damaged or destroyed in the past two-and-a-half months, displacing millions of people.
Around half a million of those displaced are living in organised camps, while others have had to find their own shelter.
Prime Minister Shehbaz Sharif said the floods badly destroyed crops, and his government was considering importing wheat to avoid any shortage of food.
Mr Sharif said Pakistan was witnessing the worst flooding in its history and any inadvertent delay by the international community in helping victims “will be devastating for the people of Pakistan”.
He promised funds from the international community would be spent in a transparent manner and that he would ensure all aid reaches those in need.
“This is my commitment,” he told reporters, saying his country is “facing the toughest moment of its history”.
According to initial government estimates, the devastation caused 10 billion dollars (£8.5 billion) in damage to the economy.
More than 160 bridges and more than 3,400 kilometres (2,100 miles) of road have been damaged.
Although rains stopped three days ago, large swathes of the country remain underwater, and the main rivers, the Indus and the Swat, are still swollen.
The National Disaster Management Authority on Tuesday warned emergency services to be on maximum alert, saying flood waters over the next 24 hours could cause further damage.
Rescuers continued to evacuate stranded people from inundated villages to safer ground.
Makeshift tent camps have sprung up along motorways.
Meteorologists have warned of more rains in coming weeks.
“The situation is likely to deteriorate even further as heavy rains continue over areas already inundated by more than two months of storms and flooding. For us, this is no less than a national emergency,” Pakistani foreign minister Bilawal Bhutto-Zardari said, urging the international community to give generously to the UN appeal.
Rainfall during that time was three times the average, and up to six times higher in some areas, he said.
The UN flash appeal for 160 million dollars will provide food, water, sanitation, health and other forms of aid to some 5.2 million people, Mr Guterres said.
“The scale of needs is rising like the floodwaters. It requires the world’s collective and prioritised attention,” he said.
A day earlier, the International Monetary Fund’s executive board approved the release of a much-awaited 1.17 billion dollars (£1 billion) for Pakistan.
The funds are part of a six billion dollar (£5 billion) bailout agreed on in 2019.
Mr Khan was ousted through a no-confidence vote in the parliament in April.
Pakistan has risked default as its reserves dwindle and inflation has spiralled, and to get the IMF bailout the government has had to agree to austerity measures.
The flooding catastrophe, however, adds new burdens to the cash-strapped government.
It also reflects how poorer countries often pay the price for climate change largely caused by more industrialised nations.
Since 1959, Pakistan is responsible for only 0.4% of the world’s historic CO2 emissions.
The US is responsible for 21.5%, China for 16.5% and the EU 15%.
“This year, Pakistan has received the highest rainfall in at least three decades,” said Abid Qaiyum Suleri, executive director of the Sustainable Development Policy Institute and a member of Pakistan’s Climate Change Council.
“Extreme weather patterns are turning more frequent in the region and Pakistan is not an exception.”
Pakistan saw similar flooding and devastation in 2010 that killed nearly 2,000 people.
But the government did not implement plans to prevent future flooding by preventing construction and homes in flood-prone areas and river beds, said Suleri.
