Dr Michelle Goliath
Dr Michelle Goliath received her PhD, providing significantly useful insights into artisanal mining. She says it is the prospect of contributing to positive change and advancing understanding in the field that has been the most exciting and fulfilling aspect of completing this research.

Dr Michelle Goliath completed her PhD in the Department of Urban and Regional Planning at the University of the Free State (UFS) and received her qualification during the December graduations. 

The PhD, which she began in 2018 under supervision of Prof Malene Campbell, is titled Urban Pacification Strategies and Solutions: Towards a Contested Space Theory of Artisanal Mining.

The focus of her thesis was on finding strategies to address informal mining in urban areas. “It considers the formalisation of informal miners, adapted land use management, risk management solutions, and action research to solve complex problems. In addition, it also looks at the social, economic, and environmental dimensions of the challenge and proposes a unique practical methodology on how to solve similar complex problems and challenges that urban planners and policy makers face daily,” explains Dr Goliath. 

A foundation for informed decision making

She is of the opinion that her research provides a foundation for informed decision making by town planners who seek to proactively address and mitigate challenges around artisanal mining.

Dr Goliath’s thesis introduces innovative strategies for managing land use specifically designed for the challenges of artisanal mining. She believes that recognising the importance of flexible and innovative land-use policies demonstrates a deep understanding of the spatial aspects involved in effectively accommodating and regulating artisanal mining activities. As reported by Dr Goliath, this customised approach ensures that the rules fit the unique characteristics of artisanal mining, promoting sustainable urban development.

Moreover, by integrating action research methodologies into the thesis, a dynamic and collaborative element is introduced into the decision-making process. She says that engaging in practical, on-the-ground research in collaboration with practitioners – in this instance a community of women artisanal miners in Kimberley – advocates for evidence-based decision making in urban planning. “This approach not only enriches the theoretical foundation of the thesis, but also ensures that the proposed solutions are rooted in the practical realities of the South African context,” she states.

Furthermore, the thesis offers both theoretical insights and practical policy recommendations, ensuring that its research findings extend beyond academia. These insights are directly applicable to the challenges confronted by town planners in South Africa and policy planners in other SADEC countries who are still navigating the policy process for similar challenges. “The incorporation of global trends in artisanal mining allows for a comparative approach, enhancing the relevance and transferability of the recommendations both locally and internationally,” remarks Dr Goliath.

The impact of empowerment

She says it is fulfilling to witness the transformative impact of empowerment. “Engaging with and supporting women in the artisanal mining sector has not only enhanced their economic opportunities but has also contributed to broader social and community development. It is the empowerment of these women, their resilience, and the tangible positive shifts in their lives that stand out as the most rewarding and impactful outcomes of my work in Kimberley.”

Besides the opportunity to help this group of women, she was also excited about the chance to contribute new knowledge and insights to the field. “The process of delving into unexplored aspects of artisanal mining in Kimberley, conducting thorough investigations, and analysing longitudinal data has been intellectually stimulating,” she states.

“The prospect of offering novel perspectives, innovative solutions, and evidence-based recommendations through my research is particularly thrilling. Witnessing the potential for this work to make a meaningful impact on policies, practices, and the lives of individuals involved in artisanal mining adds a sense of purpose and excitement to the research journey,” concludes Dr Goliath.

To tan or not to tan: a burning issue
2009-12-08

 Prof. Werner Sinclair

“Some evidence exists which implies that sunscreens could indeed be responsible for the dramatic rise in the incidence of melanoma over the past three decades, the period during which the use of sunscreens became very popular,” says Prof. Werner Sinclair, Head of the Department of Dermatology at the University of the Free State. His inaugural lecture was on the topic Sunscreens – Curse or Blessing?

Prof. Sinclair says the use of sunscreen preparations is widely advocated as a measure to prevent acute sunburn, chronic sun damage and resultant premature skin aging as well as skin malignancies, including malignant melanoma. There is inconclusive evidence to prove that these preparations do indeed achieve all of these claims. The question is whether these preparations are doing more harm than good?

He says the incidence of skin cancer is rising dramatically and these tumours are induced mostly by the ultra-violet rays.

Of the UV light that reaches the earth 90-95% belongs to the UVA fraction. UVC is normally filtered out by the ozone layer. UVB leads to sunburn while UVA leads to pigmentation (tanning). Because frequent sunburn was often associated with skin cancer, UVB was assumed, naively, to be the culprit, he says.

Exposure to sunlight induces a sense of well-being, increases the libido, reduces appetite and induces the synthesis of large amounts of vitamin D, an essential nutritional factor. The use of sunscreen creams reduces vitamin D levels and low levels of vitamin D have been associated with breast and colon cancer. Prof. Sinclair says the 17% increase in breast cancer from 1981 to 1991 parallels the vigorous use of sunscreens over the same period.

Among the risk factors for the development of tumours are a family history, tendency to freckle, more than three episodes of severe sunburn during childhood, and the use of artificial UV light tanning booths. He says it remains a question whether to tan or not. It was earlier believed that the main carcinogenic rays were UVB and that UVA merely induced a tan. The increase in UVA exposure could have severe consequences.

Prof. Sinclair says the UV light used in artificial tanning booths consists mainly of pure UVA which are highly dangerous rays. It has been estimated that six per cent of all melanoma deaths in the UK can be directly attributed to the use of artificial tanning lights. The use of an artificial tanning booth will double the melanoma risk of a person. “UVA is solely responsible for solar skin aging and it is ironical that tanning addicts, who want to look beautiful, are inflicting accelerated ageing in the process,” he says.

On the use of sunscreens he says it can prevent painful sunburn, but UVA-induced damage continues unnoticed. UVB blockers decrease vitamin D synthesis, which is a particular problem in the elderly. It also prevents the sunburn warning and therefore increases the UVA dosage that an individual receives. It creates a false sense of security which is the biggest problem associated with sunscreens.

Evidence obtained from the state of Queensland in Australia, where the heaviest and longest use of sunscreens occurred, boasted the highest incidence of melanoma in the world. A huge study in Norway has shown a 350% increase in melanoma for men and 440% for women. This paralleled the increase in the use of UVB blocking sunscreens while there was no change in the ozone layer. It did however, occur during that time when tanning became fashionable in Norway and there was an increase especially in artificial tanning.

Prof. Sinclair says: “We believe that sunscreen use does not directly lead to melanoma, but UVA exposure does. The Melanoma Epidemic is a reality. Sunscreen preparations are not the magical answer in the fight against melanoma and the irresponsible use of these preparations can worsen the problem.”
