Genesis of the crisis in Sudan-Current Affairs

Sudan, once Africa's biggest country, has been in conflict for decades. The mainly African south and predominately Arab north fought for almost 40 years over the past six decades over differences in ideology, politics, resources, land and oil.

The most recent war raged from 1983 to 2005, claiming the lives of at least two million people and leaving another four million displaced.

When South Sudan became independent in July 2011, it was supposed to usher in a new period of peace and stability in the region.

But Sudan is still highly unstable with a continuing humanitarian crisis in Darfur in the west and fighting in oil-rich regions bordering South Sudan together known as the “Three Areas”. The country is also recovering from a conflict in the east.

Southern Kordofan is region that used to be the geographical centre of Sudan, but when the south won independence, it found itself on the southern border.

At its heart is the Nuba Mountains where some 50 black African tribes have lived for thousands of years.

There was heavy fighting in the region during the north-south civil war, but the comprehensive peace agreement that ended the conflict never resolved its status.

The conflict has stopped people from tending their fields and food is running out. Aid agencies have been banned from the region, and the UN warns of a looming humanitarian disaster.
