“Strengthening the Livelihoods Resilience of Pastoral and Agropastoral Communities in South Sudan’s Cross-border Areas with Sudan, Ethiopia, Kenya and Uganda” is a three-year project funded by European Union that aims to improve governance and conflict prevention to reduce forced displacement and irregular migration in the cross-border areas of South Sudan. This publication is a baseline study and its main objective is to collect information on the indicators that will be used to estimate the impact of the cross-border project after its three year implementation. An additional objective is to gain a better understanding of the drivers of instability and irregular migration, as well as of the determinants of food security and resilience. The primary tool used in this study is the RIMA-II model developed by FAO. This report presents the results of the baseline survey; it is based on data collected by FAO and partners during July - August 2017 under the nationwide Food Security and Nutrition Monitoring Survey (FSNMS), triangulated with qualitative data from secondary sources.
