UN Secretary General Antonio Guterres on Tuesday urged the international community to take action to avert famine in Somalia where a biting drought has left three million people going hungry.
Somalia is facing its third famine in the 25 years that it has been embroiled in civil war and anarchy. A 2011 famine left 260,000 people dead in the Horn of Africa nation.
"There is a chance to avoid the worst... but we need massive support from the international community to avoid a repetition of the tragic events of 2011," said Guterres.
"It justifies a massive response," he added.
Guterres arrived in Mogadishu Tuesday morning for a whirlwind visit which will also take him to a camp of internally displaced persons in one of the hardest-hit parts of the country.
He met President Mohamed Abdullahi Mohamed, a popular leader whose recent election has sparked hope among Somalis of a more stable future for a country notorious for being the world's foremost failed state.
"The reason (Guterres) came here today is to show support and solidarity to the Somali people at this time of humanitarian crisis," said the president, better known by his nickname Farmajo.
"We have a drought which could result in a famine if we don't receive any rain in the coming two months."
While Somalia is inching closer to stability, Farmajo warned after his election that there would be no quick fixes for the country.
"Your problems were created during twenty years of conflict and droughts. A solution will need more than another twenty years," he said in an address to the Somali people last month.
The Horn of Africa nation is one of three countries -- along with Yemen and Nigeria -- on the verge of famine which has already been declared in South Sudan.
- Conflict and drought -
Conflict and severe drought are the common denominators that have led to an unprecedented number of famine alerts at one time around the world.
The United Nations said last month that $4.4 billion (4.1 billion euros) in emergency funding is needed to address the crisis in the four countries, where more than 20 million people face starvation.
In South Sudan, 100,000 people are already suffering from a "man-made" famine due to three years of civil war.
An official declaration of famine is made when 20 percent of the population in the affected area has extremely limited access to food, acute malnutrition is higher than 30 percent, and more than two per 10,000 people are dying every day.
In Somalia, the drought has led to a spread of acute watery diarrhoea, cholera and measles, and nearly 5.5 million people are at risk of contracting waterborne diseases.
On Saturday Prime Minister Hassan Ali Khaire said at least 110 people had died in 48 hours from "droughts and acute watery diarrhoea" caused by lack of food, medicine and access to safe drinking water.
"The combination of conflict, drought, climate change, diseases and cholera is a nightmare," Guterres told journalists during the flight to Mogadishu.
Several failed rainy seasons have also severely impacted other east African nations such as Ethiopia and Kenya, and much of southern Africa.
East Africans are holding their breath just weeks ahead of the main annual rains. If they fail, the situation will turn from crisis into catastrophe.
Guterres' visit to Somalia is only the third by a UN secretary general since 1993 -- two years after then president Siad Barre was overthrown, plunging the country into civil war.
Guterres' predecessor Ban Ki-moon visited in 2011 just months after the country's last famine which was Africa's worst in 20 years. He returned in 2014.
