South Sudanese surgeon Dr. Evan Atar Adaha, 52, recalls that when he announced his decision to embark on humanitarian aid work in 1997 amid the civil war in Sudan, his friends told him, "You will die if you go there. It is too dangerous."
He went anyway — and is still there.
Last month, Atar received the U.N. Refugee Agency's Nansen Refugee Award, in recognition of his more than 20 years of providing medical care for displaced people and refugees amid the ongoing conflict in Sudan and South Sudan.
