War between Ukraine and Russia will likely make the world’s hunger crisis even tougher to fight. The countries are two of the world’s major suppliers of staple grains like wheat, and a protracted crisis increases the likelihood of supply interruptions and higher food prices for many people — including those who can least afford them.

Gallup data offer insight into the populations most likely to suffer from a prolonged disruption: People in countries reliant on wheat from Ukraine or Russia, where large segments of their populations were also struggling to afford food before the war broke out.

Many of the countries on this list, including Egypt, Turkey and Kenya, are also dealing with political instability and conflict, situations only made worse when populations go hungry.
