'Green hunger' as starvation stalks fertile Guatemala

"Luis Alexander is nine months old and suffers from acute malnutrition. He appears weak and tiny in his mother's arms in front of their mudbrick house.

Ronald Estuardo Navas, a hunger monitor at the international non-profit Action Against Hunger, measures Luis's arm with a tape that evaluates the nutritional health of a child via the size of the upper arm.

'He has a perimetre of 9.9 centimetres — there's a high risk he could die,' he said."
