Hello and welcome to the documentary from the BBC World Service.

Welcome to People Fixing the World from the BBC World Service with me, Myra Anubi.
This is the programme that looks for solutions to some of the world's toughest problems,
like the impact of war.
Today we'll hear about innovative ways to get people the medical help and support that they need when their lives are turned upside down.
That's the number of people that are estimated to be living in areas affected by conflict,
according to the UN.
Now that's a quarter of the world's population.
And when fighting starts, a lot of lives are lost and crucially, governments are torn apart.
Conflict can shut down hospitals, cut off power and water,
leaving communities without even the most basic healthcare.
But on People Fixing the World, we are all about solutions.
In Sudan, we'll find out how communities have created their own emergency response networks.
And in Syria, we'll find out how broken hospital equipment is cleverly being repaired.
But first, let's talk about an innovation that could revolutionise surgery during war.
