SEHWAN, Pakistan, Sept 7 (Reuters) – Parts of Pakistan looked “like a sea”, Prime Minister Shehbaz Sharif said on Wednesday, after visiting some of the flood-hit areas covering up to a third of the southern nation Asia. where 18 more deaths took the toll from the rainy days to 1,343. As many as 33 million out of a population of 220 million have been affected in a climate change-driven disaster that has left hundreds of thousands homeless and caused at least $10 billion in damage, officials estimate. “You wouldn’t believe the extent of the devastation there,” Sharif told media after a visit to the southern province of Sindh. “It’s water everywhere as far as you can see.

National disaster officials said eight children were among the dead in the past 24 hours. The floods were caused by record monsoon rains and melting glaciers in Pakistan’s northern mountains. The raging waters have swept away 1.6 million homes, 5,735 km (3,564 miles) of transport links, 750,000 head of livestock and inundated more than 2 million acres (809,370 hectares) of agricultural land. Officials in Sindh expect the waters to recede in the coming days, provincial government spokesman Murtaza Wahab said. “Our strategy right now is to be prepared to grow wheat once the water recedes,” he added. But with more rain expected next month, the situation could worsen further, a senior official of the United Nations High Commissioner for Refugees (UNHCR) has warned. Already, the World Health Organization has said that more than 6.4 million people need humanitarian support in the flooded areas. Pakistan has received nearly 190% more rainfall than the 30-year average in July and August, a total of 391 mm (15.4 in), with Sindh receiving 466% more than average.
