The United Nations has paid nearly $8 million in salaries to some 23,500 health workers across Afghanistan over the past month, bypassing the health ministry in a test case to inject much-needed liquidity into a dire Afghan economy.

The U.N. development agency UNDP and the Global Fund health aid organization teamed up to resurrect a program that had been funded by the World Bank until it suspended assistance when the Western-backed Afghan government collapsed and the Islamic Emirate of Afghanistan (IEA) took control in August.

The United Nations has been struggling to get enough cash into Afghanistan to help deliver humanitarian aid to millions of people on the brink of famine and prevent the collapse of the economy and health and education services, Reuters reported.

“Someone had to step in. We were confronted not just with a health system that was collapsing, but also a financial system that was collapsing,” UNDP Regional Director for Asia and the Pacific, Kanni Wignaraja, told Reuters.

“Global Fund took the financial risk, we took the implementation risk to make these payments happen,” she said. “We’ve shown it’s possible, it can work … it goes a huge long way to saving at least the people’s economy in the country.”

The Global Fund provided $15 million, of which nearly $8 million was used for salaries, while much of the rest was spent on providing basic medical equipment, essential drugs and supplies, Reuters reported. UNDP worked out how to get the funds into the country and into the hands of health workers in 31 of Afghanistan’s 34 provinces.

Wignaraja said UNDP wired some of the money to the Afghanistan International Bank and then used a large money service provider, which UNDP declined to identify for security reasons, to distribute the rest.

The health workers paid so far – working in nearly 2,200 health facilities – had money deposited into bank accounts, while another 2,500 health workers will shortly be paid in cash because they are in remote areas.

“It’s given hope to these families. It’s reignited healthcare services,” said Wignaraja, adding that the program would now be run by the World Health Organization and the U.N. children’s agency UNICEF for the next three months.

“Without this, you literally would have all the Afghan doctors, nurses, technicians, heading across borders,” she added.

During that time Wignaraja said the United Nations would talk to the World Bank to see if it was then able to take over the program again or find a hybrid solution if the bank is unable to get any approvals needed to do so.

Wignaraja said the payment of health workers salaries over the past month had helped spark the re-opening of some banks.

“The minute you start the local community economic activity and people are able to deposit money and take money these banks are able to open their local branches,” she said.

After showing it could work, the United Nations would continue using the formal banking system and money service providers to get cash into Afghanistan for the next few months, Wignaraja said, although she added that U.N. agencies were also considering a need to bring U.S. dollars into the country.

“This has been for us a pretty crazy test run of the system,” she said of the payments to health workers, adding that she hoped international donors were “watching it really closely.”
