While the eyes of the world rightly look towards global crises in Iraq, Syria, Gaza, Ukraine and West Africa, there is a serious and worsening humanitarian disaster almost going unnoticed in South Sudan.
It is deeply saddening to see a country that was once so full of hope for the future, now embroiled in such a painful and destructive war with itself. When I first visited South Sudan less than two years ago I was struck by the optimism and hope that filled the air but today it is an entirely different story.
Since December violence has spread through the country forcing 1.7million people to flee their homes. The conflict between the Government and Opposition party supporters has created in its wake one of the world's worst humanitarian crises. Some 400,000 people are now refugees in neighbouring countries, numbers the UN expects to double by December.
And yet the situation could get worse as the threat of famine looms large. This year's planting season has been neglected by people fleeing their home to escape the violence and aid agencies have warned of the risk of food shortage. Already people are dying from food insecurity and the UN predicts that some 50,000 children could die of malnutrition before the year is out, even before famine is formally declared.
It is an increasingly desperate situation and last week I visited South Sudan to see for myself just how severe it is. It is clear that even now there are already chronic food shortages. At an International Rescue Committee nutrition centre in Ganyliel Town, I saw many children suffering from malnourishment. I met a young mother whose infant child was severely under-nourished and had severe medical problems. Her struggle to feed her child with the limited supply of food available to her was deeply moving.
The UK has contributed £125million to help those caught-up in this crisis. This includes £30 million I announced during my visit for refugees who have fled to neighbouring countries. This will help deliver food, shelter, basic hygiene needs, safe water, immunisation and essential supplies such as mosquito nets, kitchen sets and fuel. But the UN's Crisis Response Plan remains under-funded, and we desperately need other donors to contribute more too.
The truly appalling tragedy about this crisis is that it is wholly man-made. Ultimately aid cannot fix the problem, only help deal with the consequences. South Sudan's leaders must accept full responsibility for starting the conflict and now must work to end it. Politicians need to honour the agreements they have already made, but ignored, to stop the fighting. These were the messages I delivered to the South Sudanese Government during my visit, and which they and leaders of the armed opposition need to hear loud and clear from us all.
