Flood waters threatened to engulf two towns in Sindh on Saturday, a month after the disaster began, as the United Nations warned that tens of thousands of children risked death from malnutrition.
Floodwaters are beginning to recede across most of the country as the water flows downstream, but high tides in the Arabian Sea meant they still posed a threat to towns in Sindh province such as Thatta, 70 km (45 miles) east of Karachi.
Water had broken the banks of the Indus near Thatta and also broken out of a feeder canal running off the river, compounding the danger, said Riaz Ahmed Soomro, relief commissioner in Sindh.
“The water has not reached the town up to now but it is approaching,” Soomro said.
Tens of thousands of people have poured out of the delta town, which normally has a population of about 300,000, after authorities told people to leave.
The floods began in late July after torrential monsoon downpours over the upper Indus basin.
Even before the floods, Pakistan’s economy was fragile. Growth, forecast at 4.5 percent this fiscal year, is now predicted at anything between zero and 3 percent.
The floods have damaged at least 3.2 million hectares (7.9 million acres) — about 14 percent of Pakistan’s entire cultivated land — according to the United Nation’s food agency. The total cost in crop damages is believed to be about 245 billion rupees ($2.86 billion.)
Authorities have been battling for days to save the town of Shahdadkot in northern Sindh’s rice-growing belt, raising an embankment several kilometres long as the water has crept higher.
The flood barrier was still holding, Soomro said.
The United Nations said aid workers were becoming increasingly worried about disease and hunger, especially among children in areas where even before the disaster, acute malnutrition was high.
“We fear the deadly synergy of waterborne diseases, including diarrhoea, dehydration and malnutrition,” senior Unicef official Karen Allen said in a statement.
UN humanitarian coordinator Martin Mogwanja said the international response to the disaster must be more assertive.
“If nothing is done, an estimated 72,000 children, currently affected by severe malnutrition in the flood-affected areas, are at high risk of death,” he said.
