This week 148,000 Syrian child refugees in Lebanon are back in school. This is thanks to an innovative initiative that has dramatically changed the way we think of provisions for children in conflict.

Having been deprived of an education by a war entering its fourth year, 88,000 of these children are now benefiting from a unique timeshare experiment. The local Lebanese children, who study in French and English in the mornings, are sharing their schools to allow Syrian refugees to learn in their native Arabic during a second afternoon shift. Some Syrian refugees also attend the morning school and the shift system is allowing many more children to be educated.

In one pilot area in Akroum, northern Syria, a Scottish charity is providing the funds for Syrian volunteers and Lebanese teachers to work together. Over the past few weeks, an idea that was once merely a concept has been debated by international organisations and turned into reality. The project has got off the ground — thanks to aid given by 10 donor countries, allowing Unicef and the United Nations High Commissioner for Refugees (UNHCR) to mobilise and work in partnership with the Lebanese government.

This month, in New York, I was able to report to the UN Secretary-General, Ban Ki-moon, that the idea of education without borders is coming alive in one of the most dangerous areas of the world. This is thanks to the efforts of the UN voluntary organisations and aid agencies that have now pledged approximately $100 million (Dh367.8 million) to make the initiative work. The education of Ban himself is testimony to what can be achieved when international organisations are determined to provide education in the midst of conflict. The secretary-general was educated under a tree during the 1950s civil war between North and South Korea. He benefited from a unique scheme under which, Unesco and Unicef provided aid for child refugees of that country’s devastating war. He told me that the books he used were received — thanks to Unesco — and that printed on their back cover was a message from the UN. It said: “Work hard and you will repay your debt to the United Nations.” This is something Ban did many times over as he rose to become the first secretary-general of the UN who was brought up in the midst of a civil war.

However, 60 years on, we have yet to establish the principle that even in the throes of conflict, children will be provided not just with food and shelter, but with education as well. And we have yet to persuade aid donors that the one thing that education can provide is the vital ingredient of hope: Hope that there is a future worth preparing and planning for. Today, more than 20 million of the 57 million children who are not in school are denied education because they are victims of war. And while the Red Cross long ago proved that health care can be provided even in the most difficult and turbulent of wars, we have not yet made sure that schooling can continue uninterrupted. As a result of our failure, children who should be at school are often involved in child labour, begging on the streets, condemned to early marriage, trafficked or even recruited as child soldiers and trained to kill.

Now Lebanon can become the country where we achieve for education in 2014 what was achieved for health a century ago. We can give education to every one of the 435,000 child refugees and vulnerable children.

The provision of education beyond borders is not just a concept. It is coming alive in the most difficult of conflict zones, but it will take a demand from the public to persuade governments to do what is necessary to maintain support over the coming years. We must make sure that the right of every child to go to school — in war as well as in peace — can become a reality.
