Mass starvation looms over Yemen, Africa amid donations shortfall
Conflicts, drought and failed harvests have exacerbated food insecurity and acute malnutrition in areas where around 20 million people live, UNHCR said.
In South Sudan alone, around one million people are already "on the brink of famine," according to Edwards.
The situation in Somalia is also "vey, very dire," the ICRC's coordinator for the country, David Hermann, said. Increased displacement due to the crisis is also impacting neighbouring countries like Ethiopia, Uganda, Tanzania and Rwanda.
In Yemen, the Middle East's most impoverished nation, roughly 60 percent of the country's population is going hungry amid continued conflict.
So far, UNCHR's work in helping those affected has been impeded by a significant shortfall in funding, despite the UN agency stepping up operations.
Its efforts in South Sudan, Somalia and Yemen have only received between 3 to 11 percent of what is needed, Edwards said.
According to Jens Laerke of the UN's Office for the Coordination of Humanitarian Affairs, the UN has appealed for $4.4 billion for the four afflicted countries, but has received less than $984 million.
