On July 9, 2011, South Sudan gained independence from Sudan to the north. Since then, however, various ethnic groups have been fighting for power. From 2013 to 2018, a civil war raged between the ethnic groups Dinka and Nuer - hundreds of thousands of people died and several million fled to other parts of the country or to neighboring countries. Most of the medical infrastructure was destroyed. In addition to the consequences of the armed conflict, the challenges in the East African country include a very high illiteracy rate as well as droughts and floods. In addition, the drinking water of hundreds of thousands of South Sudanese is polluted by the oil industry. According to the Human Development Report 2021/2022, more than ten million people live in the landlocked country.
