(The Guardian) – At the world humanitarian summit next week in Istanbul, Turkey, governments have a rare opportunity. By getting behind an initiative aimed at delivering education to some of the world’s most vulnerable children, they could make this a summit that delivers something more than vague promises and a communique that is long on words and short on action. The initiative comes in the form of a ground-breaking financing mechanism. The Education Cannot Wait fund will be launched at the summit by the UN special envoy for education, Gordon Brown, and a group of development agencies, including Unicef, UNHCR – the UN refugee agency – and the Global Partnership for Education.
