“The benefits of the first weeks of truce are already significant,” said Erin Hutchinson, Yemen Director for the Norwegian Refugee Council. The group has been able to give aid to 12,000 people in one district of Hajjah province that has not been reached for more than three years.

More than seven years of conflict in Yemen have devastated the economy, displaced millions and pushed food prices out of the reach of many. Spiking global grain and commodity prices are adding further strain.

“Tens of millions of people in Yemen are living hand-to-mouth,” said Richard Ragan of the World Food Programme (WFP), which is trying to feed half of Yemen’s 30 million people in one of its largest ever programmes.

Stunted and weakened by severe malnourishment, one-year-old Jiad Jalal’s skin is dry and wrinkled over his protruding skull, limbs and stomach. Living in a makeshift displacement camp in Khadish, Hajjah, one of Yemen’s poorest regions, Jalal is one of 2.2 million children under five — including 538,000 severely malnourished — who will suffer acute malnutrition this year, according to pre-ceasefire UN estimates.

“We eat only what we can get from aid agencies. Wheat, beans and such items. If we don’t receive food, then some days we eat and other days we go hungry,” said his grandmother Zahra Ahmed.
