The Somali people of Ethiopia's southeast have a name for the drought that has killed livestock, dried up wells and forced hundreds of thousands into camps: sima, which means "equalized".

It's an appropriate name, they say, because this drought has left no person untouched, spared no corner of their arid region. And it has forced 7.8 million people across the whole of Ethiopia to rely on emergency food handouts to stay alive. But by next month, that food will have run out, aid agencies say.

Droughts are common in Ethiopia, and in past years the government and international community have mounted impressive efforts to curb starvation. This year though, Africa's second most-populous country is struggling to find the money for food aid, say aid agencies.

"We're looking at the food pipeline actually breaking, so the food is running out in about a month's time," said John Graham, country director for Save the Children. "After that, we don't know what's going to happen."

Once a global byword for starvation and poverty after a famine in 1984-85 killed hundreds of thousands, Ethiopia has seen its economy grow rapidly in the last decade. Health indicators such as infant mortality and malaria deaths have also improved.

A stronger economy allowed Ethiopia to spend an impressive $766 million (683 million euros) fighting one of its worst droughts in decades in 2015-16. This year however, things are different. Economic growth has slowed, due in part to protests spurred by long-simmering grievances against Ethiopia's one-party state. Donors have also been distracted by other regional crises. To the southeast, Somalia is suffering from severe drought, with warnings it could tip into famine.

Ethiopia's western neighbor, South Sudan, has suffered four months of famine, and extreme hunger is at its highest levels ever after more than three years of civil war. Ethiopia by contrast has a strong central government and is relatively free from conflict.

Even though Ethiopia has contributed $117 million of its own money this year and the international community $302 million, a funding gap of $481 million remains, according to the United Nations. In the drought ravaged town of Warder, the hundreds of displaced families crowding a ramshackle camp say handouts of rice and sugar are becoming less frequent.

"Skipping meals is common," said Halimo Halim, a grandmother living with her children in a shelter made of sticks and pieces of plastic. "Skipping is the order of the day." Families of nomadic herders such as Halimo's are central to the economy of Ethiopia's southeastern Somali region. The drought has deprived goats, sheep and donkeys of water, killing them or making them so weak that by the time the rains come they perish in the cold. Around 465,000 people who have lost their livestock have migrated to an estimated 250 camps in the region.
