Some 30 percent of Kibera's 3 million residents go without food.
This is according to a recent study in the area by City Hall in partnership with the Kenya Red Cross, World Concerns and Oxfam.
According to the survey, some of the children in the slums are at a risk of dying of malnourishment.
The Early Warning and Action Mechanism Strategy survey revealed that poverty was a key factor in denying the residents the basic needs.
“It is very unfortunate that while a section of the city residents have enough food and only focus on its safety, the other section cannot afford even a meal in a day,” said Nairobi Agriculture executive Njuguna Wachira.
“People in Mukuru, Kibera, Korogocho, Kawangware and most of these slums are suffering and hungry. In Korogocho, we found about 200 families in pathetic situation and they need help,” Wachira revealed.
