This thesis discusses the conditions of social interaction in development projects in the rural Nuba Mountains (Sudan) between 2005 and 2011. Above all, the study examines conditions of structural instability in the region, which are also reflected in processes of planning and implementation supposedly technical in nature. The concepts ‘problematization’, ‘translation’ and ‘organizing principles’ are used in order to grasp the complex relation between political and technical problems. The analysis is based on the results of overall 12 months of fieldwork (participant observation, narrative interviews) at different places in the Sudan (Khartoum, Kadugli, Heiban, Abol, Kubang). Beside relevant regional studies, the written sources included historical documents (letters, reports of the colonial administration) from the Sudan Archive in Durham, recent governmental documents, as well as documents of national and international development organizations.
