The growing humanitarian crisis in Abyei area triggered the idea of founding “Abyei Community Action for Development” that first emerged during 1999-2000 towards the end of the 20th during 1999-2000 towards the end of the 20th Century and the Second Millennium. A group of concerned sons and daughters from Abyei area started informal discussions and consultations in Nairobi, Kenya of what they could do as a community to address the humanitarian crisis in the area. These consultations culminated in tasking late Deng Mading, the first executive director of ACAD, and Dr.Luka Biong Deng, the first chairperson of the Board of Trustees of ACAD, to work on a concept paper for the establishment of a community-based organization to address not only the humanitarian crisis but also to advance community-centric development not only in Abyei area but also in the neighboring communities in northern Bahr el Ghazal region and northern Upper Nile region. The draft concept paper for the establishment of ACAD became available in 2001 at the beginning of the 21st Century and the Third Millennium. This draft concept paper became the basis for consultation among the sons and daughters of Ngok Dinka of Abyei area in Nairobi, Kenya and refugee’s camp in Kakuma, Kenya. These consultations resulted in the production of the revised draft concept paper that became a basis for launching in 2001 at Abyei Primary School in Panlit village, Twic County, the birth of ACAD in a community meeting attended by over 500 participants representing the nine chiefdoms of the Ngok Dinka, women and youth. This community meeting had not only endorsed the revised concept paper for the establishment of ACAD but it also blessed the birth of ACAD through traditional ritual ceremony.
