Sudan faces multiple crises.  The CPA, which ended the southern conflict, has not been fully implemented.   International support has been patchy.   Demarcation of the North/South border has again been postponed. Preparations for the southern and Abyei referenda, due to be held in January, are well behind schedule, as are the popular consultations in Blue Nile and South Kordofan, where state elections have been put off until November.  Inter-tribal conflict troubles the South.  Opinion is increasingly polarized as the southern referendum approaches and the risk of renewed conflict grows, with damaging implications for the region and Africa as a whole.
