Southern Sudan, 2008:

Nya and her mother have taken Akeer to the doctor and she is now much better. They are told that Akeer was sick because the water was dirty. They need to boil the water to kill the germs, but if they boil the water for that long all the water will evaporate. 

Southern Sudan, 1985:

After paddling for hours, the group reaches an island that is a fisherman’s village. They had a lot of food because of their access to water. The villagers give Salva’s uncle food, though Salva doesn’t know if it is because he carries a gun or because he is the leader. The other members of the group have to beg for food. That night, the fishermen go inside mosquito netting while Salva’s group is horribly bitten by the mosquitoes. They are warned to bring lots of water for the next part of their journey: the desert. Some people do not have containers for water and soak pieces of cloth in water instead.
