evidence: The Abyei Area covers 4,000 square miles of desert, farmland, and oil fields located along the ill-defined border between Sudan and South Sudan. Abyei is claimed by both countries and has been a source of conflict in the Sudans for over 50 years. Abyei’s rich oil reserves make the region economically desirable to both Sudan and South Sudan. Its border location has also led to conflicting ethnic, cultural, and linguistic claims. Resolving the status of the Abyei Area is one of the essential steps Sudan and South Sudan need to take to ensure long-term peace in the region. [...] Abyei is the traditional homeland of the Ngok Dinka, a tribal group with strong ethnic, cultural, and linguistic ties to the Dinka of South Sudan. Misseriya herders, members of a northern nomadic Arab tribe, seasonally traverse Abyei and other North-South border areas with their cattle in search of water and pasture in the dry season and to trade goods.
