N uba Relief, Rehabilitation and Development Organization (NRRDO) was established in 1993, as a membership organization following the meeting called by Nuba Advisory Council in the same year.
The exclusion of the Nuba Mountain Region from Operation Lifeline Sudan (OLS) mandate was the catalyst that prompted people of Nuba Mountains, Southern Khordofan to look for ways in which the suffering of the people of Nuba Mountains in the SPLM/A controlled areas can be alleviated as well bringing it to the attention of the International Community, hence the birth of NRRDO.
The aim at the time was to publicise the Nuba cause to the outside world while at the same time soliciting and managing humanitarian assistance to the Nuba people.
Nuba Relief, Rehabilitation Development Society (NRRDS) as it was then called started its operations in 1995 by coordinating international NGOs, and journalists in highlighting and bringing to the attention of the outside world the plight of the people of Southern Khordofan/Nuba Mountains.
Among the first international NGOs to respond to requests for assistance was Christian AID in 1994, others such as Swiss Agency for Development and Cooperation, Church of Sweden, Dan church Aid (DCA), Diakonia, Koinenia, and HART. Since its formation, NRRDO has continued supporting the communities through the civil authorities in the provision of basic as well as some form of development interventions.
NRRDO continued to offer the much-needed basic assistance to the communities of Nuba Mountains/Southern Khordofan, despite the threats and embargoes by the Government of Sudan (GOS) on any humanitarian assistance to SPLM controlled areas of Nuba Mountains.
