Sudan is in a critical political, socio-economic and demographic transition, particularly in the post-cessation era, together with emerging national opportunities and challenges vis-à-vis the changing governance in the Arab region and the internationally down-turning economies. The newly two established post-cessation countries (Sudan and Southern Sudan) have serious disputes and a long trail to reach a peaceful coexistence. Although the Government has recently signed Peace Agreement in Doha with some of the Darfuri rebel movements, brutal fighting is perpetual in South Kordofan, Blue Nile, and some pockets in Darfur.
