Many are put up by relatives in some of the 19 impoverished camps that shelter an estimated 34,000 people in the area.
"There is an emergency situation in terms of nutrition," especially for children under the age of five, in these camps, says Javier Fernandez Espada from Medecins sans Frontieres (Doctors Without Borders).
In Boqolka Bush camp, Obah Abdi, a pretty 23-year-old woman from Mogadishu is still recovering from the grueling seven-day journey from the capital.
"I want to go anywhere, I don't want to be in Somalia any more," she says.
Fatuma Mohamud, 22, is in a similar situation.
"I was told that you can do everything in Bosaso and find a job. I was tired of seeing people injured and bleeding all the time," she says.
"I will never go back to Mogadishu. If I find enough money, I want to cross to Yemen."
