M.A. / This mini-dissertation establishes the extent to which small scale artisanal diamond mining impacts on the environment. There has, in the past, been research undertaken specifically on the water related impacts of small scale artisanal diamond mining. This study however, looks at the environment holistically, and gauges the total degradation to the receiving environment. Small scale artisanal diamond mining is considered to be a major contributor to the local economy and improved quality of life for the communities participating in this mining and is being actively supported through the National minerals and mining policies. It is for this reason that it was deemed imperative to understand the nature of the mining and the associated environmental impacts so that the outcome of this report could be used to inform decision makers when considering the licencing and management of artisanal diamond mining operations. In order to achieve the aim of the study, a literature review needed to be conducted focusing on the nature of small scale diamond mining operations, its influence on the social and economic spheres and the known environmental damage induced by such mining activities. However, in order to internalize the impacts, the literature review also drew a comparison with large scale artisanal diamond mining. The problems identified at the four sample sites were evaluated through the OWL Risk Assessment method to gauge the high risks and major impacts. This study showed that water pollution, biodiversity depletion and waste generation were some of the main problems traversing all four sites. In all cases assessed, artisanal diamond mining impacts on the water regime as mining takes place within the riverine environment. This study also underscored the fact that there is very little, if any rehabilitation, of disturbed areas and this impacts upon fitness for use of the receiving environment in the long term. An urgent need exists for monitoring and regulating artisanal diamond mining so as to reduce the impacts to the receiving environment. More enforced regulation will also ensure that the mining operations practice responsibly with due care for the environment coupled to a legal undertaking for rehabilitation of the mining area.
