This report investigates the rural inter-communal conflict as a threat to community livelihood in Jonglei State, one of the ten states in South Sudan. Jonglei State has a long history of unrest, which has also affected other parts of the country. Cattle raiding and conflict have manifested in Jonglei State and the surrounding communities for many years. Many people have lost their lives, and livestock losses have been abundant. It is vital that local government understands and contextualises these challenges so that appropriate interventions may be developed. This study proposes to provide a brief historical background on the evolution of inter-communal conflict in Jonglei. There have been recent changes in the security situation and increased access to weapons. Advanced weaponry has also led to a rise in insecurity and increases in the number and scale of cattle raids. Political tensions and political instability have also emerged. The political situation is unstable and political factions are in constant disagreement. Furthermore, there are limited economic opportunities there is also limited access to natural resources such as water and grazing land for cattle. Climate conditions and migration patterns are also discussed and explained. The cross sectional descriptive survey was used in this study. Various recommendations flowing from the results of the study are proposed in the final chapter. If adopted, these recommendations could enable the Government of South Sudan and the residents of Jonglei to overcome inter-communal conflict
