Within weeks, a famine could be declared in , affecting more than 850,000 people in two of the country's worst drought-affected areas plus thousands of people in displacement camps.
Such a declaration by the and partners is rare and a sign of the dire consequences from the worst drought in decades in the .
Here's a look at famine and its toll.
What does famine mean?
Famine is the extreme lack of food and a significant death rate from outright starvation or malnutrition combined with diseases such as cholera.
A declaration means data show more than a fifth of households have extreme food gaps, more than 30 percent of children are acutely malnourished and over two people out of 10,000 are dying every day.
Formal famine declarations by the United Nations and partners, including food security experts, are rare because data to meet the benchmarks often cannot be obtained because of conflict, poor infrastructure or politics.
Governments can be wary of being associated with a term of such grim magnitude.
How often does famine occur?
The last significant famine declared anywhere in the world was also in Somalia, in 2011.
By then, experts say, the deaths of a quarter-million people were well underway. Half of those dying were children under five.
The only famine declared since then was in two counties in South Sudan in 2017.
"Tragically, by the time a famine is declared, it’s already too late," the UN World Food Programme has said.
But a famine declaration is still seen as useful in drawing international aid and attention, even though it carries no binding obligations for the UN or member states.
By the time of a famine declaration, already weakened people are succumbing to malnutrition and diseases such as cholera more and more quickly.
"Unfortunately, the nature of these crises is such that they go slow and then go very fast," Sarah Charles, assistant to the administrator for USAID's Bureau of Humanitarian Assistance, told The Associated Press earlier this year.
What can famine do to a person?
A vivid description was offered last month by the CEO of the International Rescue Committee, David Miliband, in a warning about Somalia.
"Children with severe malnutrition grow thin, weak and lethargic," he said.
"They have near constant diarrhea. Their muscles atrophy as all but their body's most essential systems shut down. On top of the physical symptoms, they emotionally withdraw, becoming disengaged with the world around them.
"In the longer term, malnutrition can lead to poor immunity to severe infections, stunted growth and restricted ability to learn."
On a recent AP visit to northern Kenya, which is also affected by the Horn of Africa drought, expert Robert Ackatia-Armah noted that when a child slips from moderate to severe malnutrition, their risk of death increases ninefold.
