It has been six years since the world had a famine, but now UNICEF report that nearly 1.4 million children are at ‘imminent risk’ of death from famines in Nigeria, Somalia, South Sudan and Yemen. The World Food Programme says over 20 million lives are at risk in the next six months. Time is running out. Famine was formally declared on Monday in parts of South Sudan, mired in civil war since 2013. The conflict has split the country along ethnic lines, leading the UN to warn of potential genocide. South Sudan has also been hit by the same east African drought as Somalia, where six years ago 260,000 people starved to death. A World Food Programme report said, ‘By 2050, climate change and erratic weather patterns will have pushed another 24 million children into hunger. Almost half of these children will live in sub-Saharan Africa.
