Southern Sudan at odds with itself:

Dynamics of conflict and predicaments of peace

This report's main undertaking is to deliver information that clarifies the reasons for increased intra-south violence. By reflecting on how people living and working in Southern Sudan have experienced events since the CPA, the report looks at ways in which intra-southern structures and international approaches have created some of the current predicaments of peace, and have contributed to the dynamics of ongoing conflict. It questions established narratives about the influence of the government of Khartoum or ‘tribalism’ being at the heart of the region’s problems. The report finds that other issues, some of which have been ignored or underemphasised – such as the lack of internal border demarcations – have a direct impact on local violence. It also identifies problems with the development/reconstruction/peace-building approach that have exacerbated tensions.In particular, current attempts to establish state institutions, notably at the local level, are actually making outbreaks of violence more likely.

Above all, the report demonstrates the importance of moving away from simplistic categorisations in order to arrive at a more
multi-faceted analysis, one that takes into account the complexities on the ground.

Authority and Identity in Contemporary and Historical Perspectives

Palgrave Macmillan

Current international discourse on the new state of South Sudan seems fixated on 'state construction'. This book aims to broaden the debate by examining the character of regulatory authority in South Sudan's borderlands in both contemporary and historical perspective. The contributions gathered here show that the emerging border governance practices post-independence challenge the bounded categorization of 'state' and 'non-state', especially in the complex interactions between 'state', military, and business actors and power structures. It thus provides a timely and sophisticated contribution to the literature on African borderlands, examining a new state in creation at its borders, and providing an anthropologically and historically informed view of a rapidly evolving situation.
