Text: The aim of this article was to assess and identify social vulnerability of communal farmers to drought in the O.R. Tambo district in the Eastern Cape province of South Africa using a survey **data** and social vulnerability index (SoVI). Eleven social vulnerability indicators were identified using Bogardi, Birkman and Cardona conceptual framework. The result found that an SoVI estimated for O.R. Tambo district was very high with a Likert scale of 5 for cultural values and practices, security or safety, social networks, social dependence, preparedness strategies and psychological stress attributed for the high value of social vulnerability to drought. Indigenous knowledge and education had an SoVI value of 2, which was of low vulnerability, contributing positively to resilience to drought. The study also found that government involvement in drought risk reduction is limited; as a result, the study recommends that a national, provincial and district municipalities policy on drought risk reduction and mitigation should be developed. White and Howe (2002) argued that there is a realisation that effective natural hazard prevention and mitigation will need to address not only the hydrological-meteorological factors but also the economic and social factors which influence the greater society and reinforce the impact of hazardous events. Wilhite (2005) stated that social vulnerability to drought is increasing at an alarming rate in many parts of the world and South Africa and O.R. Tambo district is not an exception.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
