Mariam, a mother of five, is sitting outside the small shelter her family built after they fled to Kongoussi, in northern Burkina Faso, after armed groups made life in their village unbearable. "My biggest worry as a mother is that my children are hungry, and I don't have enough food to feed them. Sometimes they cry because they are so hungry, and it breaks my heart. They don’t grow like they used to do in our village. They are losing weight, and so am I. Some days I skip my meal to save a small portion for them for the evening. I used to be a beautiful woman but look at me now. I’m hungry all the time. It’s hard," said Mariam.
