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.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
