Now to the horn of Africa - specifically Somalia, where hundreds of thousands of people - many trapped by conflict - are facing extreme hunger and death after the worst drought in 40 years.
With more, here’s our World News Editor, Kate Gregan.
Over the past two years, the drought has killed millions of livestock and destroyed crops.
And now - the situation in Somalia is getting even worse.
A full-blown famine - where households have no food, children suffer malnutrition, and people die every day from starvation - is now likely within a matter of weeks.
The BBC’s Andrew Harding visited a hospital in Baidoa - a city at the heart of the crisis.
"The images here are just horrific. Bed after bed with emaciated, with desperately thin limbs, you can see their bones poking out of their rib cages, many of them with broken, raw skin that's caused by malnutrition, some of them with horrifically swollen ankles and feet too."
And the doctor in charge says - even at this relatively early stage of the crisis - there’s already a lack of supplies.
"It's actually terrifying because people are dying and you cannot support them."
The horn of Africa and eastern parts of the continent have a long history of droughts.. but the climate shocks are becoming more frequent, and they're leaving less time to recover and prepare for the next.
The situation is also made much worse by the presence of al-Shabab [Al Sha-baab] insurgents.
They control quite a few parts of the country, and they are making humanitarian work pretty much impossible.
It's thought a quarter of a million people died in the 2011 famine -- many because al-Shabab wouldn’t allow most aid in or, often, suffering people out.
And while some help is reaching the country, a distracted world has been slow to focus on Somalia’s latest struggles.
"My name is Charles Nzuki and I'm the head of UNICEF office in the central-south of Somalia.
"Time is of the essence and I think if we are going to ___ the catastrophe of famine we need to act now. We need more help, we need more supplies, we need more people on the ground and people moving around to provide support for the population."
The World Food Programme says tens of millions of people in Africa are at risk of famine and death.
In Kenya, half a million are on the brink of a hunger crisis.... and in Ethiopia, more than 20 million people need food support.
