I think the issue is that many people being targeted are farmers, so that means the crops for the next season are going to be lacking. That's one of the issues causing food insecurity. The second is that three million people are internally displaced. They're not harvesting their own food; they're dependent on receiving food. That is also one of the pressure points. It's also difficult for them to have access to food.
The violence is creating problems in receiving food, and more people are dependent on receiving food and are not able to cultivate or produce their own crops.
