INSIGHT-Locked out by COVID, refugees' lives on hold

* Resettlements suspended for thousands of refugees

* U.S., other refugee intake plummets as climate hardens

* Many stranded in areas vulnerable to spread of COVID-19

DAKAR, Aug 31 (Reuters) - When Michelle Alfaro left her office at the United Nations in Geneva on March 13, her job finding homes for the world's most vulnerable refugees was under control.

Four days later, the new coronavirus had knocked it into chaos. Governments across the world announced border closures, lockdowns and flight cancellations. The United Nations was forced to suspend the programme.

"Everything collapsed that week," said Alfaro, who manages resettlements for the U.N. refugee agency, UNHCR.

Millions of people have been thrown into limbo by the new coronavirus. Those Alfaro works with had been promised escape from war, violence, conflict or persecution. After submitting to a review process that can take years, and winning a chance to make new lives in countries such as the United States and Canada, thousands suddenly learned - often by phone - their flights would no longer take off.

Ubah Mohamed was one of them. A 23-year-old Somalian, she ran away from her husband after he tried to force her to join the Islamist group al Shabaab, militants who would later kill her father. She was due to fly to the United Kingdom on March 24.

"I didn't know where I was going," she said of her five-year ordeal as a refugee. "I was just going. I had no control."

In the first half of 2020, refugee resettlements fell 69% from 2019 levels to just over 10,000, U.N. data show. The programme resumed in June, but at a much slower pace.

The pandemic has hit as attitudes to immigrants have been hardening, loosening another thread in increasingly frayed international efforts to maintain global solidarity.

Nationalism, fear of infection, economic worries and ageing voters' resistance to change are undermining a long-established post-war consensus that people at risk of persecution, abuse or violence deserve to be sheltered.

The British government this month asked the armed forces to help deal with a rise in the number of boats carrying migrants from France. In Greece, the government has rebuffed thousands of migrants from Turkey this year and stiffened patrols to stop refugees arriving by boat. The European Union has pumped billions of dollars into African states in an attempt to stem the flow of migrants to its southern shores .

The United States rehouses the largest share of refugees in the programme, which in recent years has accounted for the majority of U.S. refugee intake. Arrivals under the programme have more than halved under President Donald Trump, who came to power in 2017 on an anti-immigration platform and is running for re-election promising more of the same. America accepted one-third of the refugees resettled by the United Nations last year, but is cutting its intake.
