South Sudan, located in northeastern Africa, has a rich variety of flora and fauna in its rainforests and savannahs, with the Nile River running along the entire length of the country. The economy is heavily dependent on oil and agriculture, and the population (which is largely rural) faces high levels of poverty and lack of amenities. One of the most well-known conflicts in the world, the civil war between what has become Sudan and South Sudan raged for nearly 50 years and brought devastation to the country. In addition to political instability, South Sudan faces challenges emanating from its high illiteracy rate, lack of infrastructure and urban development, and low levels of food security. Unfortunately, healthcare is another major concern, with only 17% of children being fully immunized and making the country more vulnerable to outbreaks of disease.
