After the referendum in South Sudan, there is still much work that needs to be done. We must urgently focus on:
1) Achieving an agreement between north and south Sudan that protects citizenship rights following the south's likely separation;
2) Upholding commitments made by both parties to protect civilians, especially minority communities in the north and south;
3) Providing basic services and security for people returning home to the south after years in exile.
Tell President Obama that 2011 is a critical year for the peace process in Sudan. He must do everything he can to ensure that the needs of returning and displaced people are met.
