Pakistan’s deadliest floods in decades killed more than 1,500 people and overwhelmed government efforts to provide aid, officials and relief workers said. More than 1,500 people have died in Pakistan’s northwestern province, Khyber Pakhtunkhwa, said Noor Muhammad, a press officer for the provincial development ministry. Government and private relief agencies are managing to provide “only 5 percent of what’s required,” Mujahid Khan, provincial spokesman for the Edhi Foundation, which runs Pakistan’s largest ambulance and rescue services, said by phone from Peshawar.

The flood’s death toll may rise to 3,000, said Edhi Foundation’s Khan. He spoke from Peshawar, the capital of Khyber-Pakhtunkhwa, previously called the North-West Frontier Province.

Officials in Pakistan’s other provinces — Punjab, Sindh and Baluchistan — braced for the floodwaters moving down the Indus River and its tributaries. The Sindh government ordered residents evacuated from locales along the Indus.

The floods, which according to U.K. charity Oxfam may be Pakistan’s worst in 35 years, may cut the production of rice, sugarcane and corn by about 10 percent to 15 percent, said Nasir Cheema, president of Pakistan’s Chamber of Agriculture.

Pakistani television networks showed survivors clinging to trees or debris in muddy, raging mountain rivers.
