THERE are 20m refugees worldwide, most of them children. Some 1.6m Syrians live in Lebanon; even more in Turkey. Humanitarian agencies struggle to meet their basic needs. In July the World Food Programme (WFP) cut assistance to refugees across the Middle East, saying that its regional operation was 81% underfunded. One way to make scarce aid money go further, argues a report* released this month by the Overseas Development Institute and the Centre for Global Development (CGD), two think-tanks, is for donors to give less in kind and more in cash.
