The objective of the study was to assess the current sustainability of small-scale sheep farming systems in the Hantam Karoo, Northern Cape Province (South Africa). The influence of economic, social, and environmental variables (indicators) in promoting the development of sustainable sheep farming was taken into account. Thirty-two small-scale sheep farmers were interviewed using questionnaires which consisted of structured and unstructured questions. The results showed that the sheep farming

Secure tenure was a major challenge to small-scale farmers. With regard to environmental variables, grazing conditions were poor. In 2017, stocking density was within the norm, which means that frequent droughts and continuous grazing methods rather than sheep stocking rates were probably responsible for poor grazing conditions. Extension advisors could teach the practice of rotational grazing and it might be a good idea to promote gender equality in order to alleviate poverty and increase food security.
