Over one-third of Pakistan underwater amid its worst floods in history

More than one-third of Pakistan is underwater amid its worst floods in history, according to satellite images from the European Space Agency (ESA).

As deadly floodwaters threaten to create secondary disasters, food is in short supply after water covered millions of acres of crops and wiped out hundreds of thousands of livestock, reported CNN.

Torrential monsoon rainfall -- 10 times heavier than usual -- has caused the Indus River to overflow, effectively creating a long lake, tens of kilometres wide, according to images from the ESA on August 30.

Pakistan is facing twin food and health crises brought by the unprecedented floods.

According to the charity Action Against Hunger, 27 million people in the country did not have access to enough food prior to the floods, and now the risk of widespread hunger is even more imminent, reported CNN.

"Our priority right now is to help save and protect lives as waters continue to rise. The scale of these floods has caused a shocking level of destruction -- crops have been swept away and livestock killed across huge swathes of the country, which means hunger will follow," said Saleh Saeed, chief executive of the Disasters Emergency Committee, a United Kingdom-based aid coalition.

Prime Minister Sharif said on August 30 that people were facing food shortages and the price of basic items such as tomatoes and onions had "skyrocketed."

"I have to feed my people. Their stomachs cannot go empty," Sharif said.

The WHO has also classified Pakistan's worst floods on record as an emergency of "the highest level," warning of a rapid spread of disease due to the lack of access to medical assistance.

World Health Organization (WHO) chief Tedros Adhanom Ghebreyesus warned of new outbreaks of diarrheal diseases, skin infections, respiratory tract infections, malaria and dengue in the aftermath of the floods, while a litany of waterborne diseases also posed health risks.

Meanwhile, aid agencies have warned of an uptick in infectious diseases, leaving millions vulnerable to illness caused by what the United Nations has called a "monsoon on steroids."

More than 1,100 people have died from the floods since mid-June, nearly 400 of them children, while millions have been displaced, according to Pakistan's National Disaster Management Authority (NDMA).

Pakistan, which was already grappling with political and economic turmoil, has been thrown into the front line of the human-induced climate crisis.

Pakistan's monsoon season usually brings heavy downpours, but this year's has been the wettest since records began in 1961, according to the Pakistan Meteorological Department

In the southern Sindh and Balochistan provinces, rainfall has been 500 per cent above average as of August 30, according to the NDMA, engulfing entire villages and farmland, razing buildings and wiping out crops.

Pakistan is responsible for less than 1 per cent of the world's planet-warming gases, European Union data shows, yet it is the eighth most vulnerable nation to the climate crisis, according to the Global Climate Risk Index.

And it's paying a hefty price -- the South Asian country faced dramatic climate conditions this year, from record heat waves to destructive floods -- as the climate crisis exacerbates extreme weather events, reported CNN.

UN Secretary General Antonio Guterres has warned the world is "sleepwalking" into environmental destruction.

"South Asia is one of the world's global climate crisis hotspots. People living in these hotspots are 15 times more likely to die from climate impacts," said Guterres.

"As we continue to see more and more extreme weather events around the world, it is outrageous that climate action is being put on the back burner as global emissions of greenhouse gases are still rising, putting all of us -- everywhere -- in growing danger," he added.

Pakistan is also home to more glaciers than anywhere outside the polar regions. But as the climate warms, it's becoming more vulnerable to sudden outbursts of melting glacier water.

Pakistan's Prime Minister Shehbaz Sharif said that the floods were "the worst in the country's history" and estimated the calamity had caused more than USD 10 billion in damages to infrastructure, homes and farms.

More than 33 million people have been affected, or about 15 per cent of the population, according to Pakistan's climate change minister Sherry Rehman. More than 1 million homes have been damaged or destroyed, while at least 5,000 kilometers of roads have been damaged, according to the NDMA.

Floods have impacted 2 million acres of crops and killed more than 794,000 heads of livestock across Pakistan, according to a situation report from the UN Office for the Coordination of Humanitarian Affairs.

More than 800 health facilities have been damaged in the country, of which 180 are completely damaged, leaving millions of people lacking access to health care and medical treatment, as reported in many affected districts, according to WHO.
