Gaza and Haiti are on the brink of famine, experts say. Here’s what that means.

Catastrophic hunger is so dire in two world hotspots that famine is imminent in northern Gaza and approaching in Haiti, with hundreds of thousands of people in both places struggling to avoid starvation.

That’s according to international food security experts and aid groups, who are warning about the toll from hunger caused by the ongoing war between Israel and Hamas in Gaza and the crisis in Haiti caused by gangs attacking the country’s key government institutions.

In Gaza, virtually every resident is struggling to get enough food and 1.1 million people — half the population — are expected to face the highest level of severe hunger in coming weeks, according to a report from the Integrated Food Security Phase Classification, an agency that monitors hunger globally. On Monday, the group warned that famine could occur in Gaza any time between mid-March and May without an end to hostilities and immediate access to essential supplies and services.

In Haiti, about 1.4 million people are on the verge of famine and more than 4 million need help accessing food, aid groups say.
