Hundreds of thousands of Nigerian children are at risk of acute malnutrition due to food insecurity.

Nigeria has the largest number of food insecure people globally at 31.8 million, according to the UN Food and Agriculture Organization.

Aid workers say they are already overwhelmed with cases of malnutrition among children.

Rising food prices, attacks by armed groups, and climate change are exacerbating a risk of a humanitarian crisis in Nigeria’s northeast, affecting millions.
