The civil war has displaced more than 4 million southerners. Some fled into southern cities, such as Juba; others trekked as far north as Khartoum and even into Ethiopia, Kenya, Uganda, Egypt, and other neighbouring countries. These people were unable to grow food or earn money to feed themselves, and malnutrition and starvation became widespread. The lack of investment in the south resulted as well in what international humanitarian organizations call a "lost generation" who lack educational opportunities, access to basic health care services, and little prospects for productive employment in the small and weak economies of the south or the north.
