Dr Martin Clark
Dr Martin Clark, the founder of the MAGIC (Multi-purpose Aerial Geological Image Classification) initiative. MAGIC can obtain geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes.

Mining has historically been described as a boom-and-bust industry, where fluctuations in mineral prices could result in extreme success or bankruptcy. Successful mining companies closely monitor assets/expenditures, risks, and other parameters associated with their business to best ensure their longevity. In most mineral industries, there are a few competitors that dominate the delivery of a mineral resource. As a result, technological development, along with other factors, are critical to ensure that these companies’ business remains viable and protected.

This is according to post-doctoral fellow in the Department of Geology, Dr Martin Clark.

Drone technology: better, faster, safer

He says technological development in mining generally translates to how a company can extract a resource from the ground better, faster, and safer. 

Dr Clark believes the rapid development of drone technology represents a shift in the toolbox that mining companies can employ.

“Drones can collect a great deal of data randomly over vast or small areas within hours, historically accomplished by mapping campaigns which can last months to years. Drones can also collect data in areas which are difficult and dangerous for humans to get to. These include cliff faces or rock walls that are difficult and dangerous to get close to, as well as stretches of land where dense vegetation, inaccessible terrain, and even atmospheric dangers become factors which reduce or modify the scope of exploration work,” he said. 

Expanding application of drones

Dr Clark’s work specifically focuses on expanding the applications for which drones are used. “I assess what and how good the imaging capabilities of drones are, use the imagery to generate 3-D models to drive scientific observation, and yield results which can help companies to extract resources. This initiative is called MAGIC (Multi-purpose Aerial Geological Image Classification),” he said. 



“MAGIC aims to collect geological and structural information that is critical for making informed decisions in exploration and mineral extraction processes,” he added.

Dr Clark is not only the founder of MAGIC; he also drives multiple aspects of the initiative including education, research, and business development. 

In 2013, when he was busy with his doctorate, there was already a spark of interest in using drones to address geological questions. At that time, Dr Clark was working with remotely sensed high-resolution LiDAR imagery to better understand geological structures at the Sudbury Mining Camp in Canada. The interest became a reality in 2018, when he applied this initiative during his post-doctoral fellowship at the UFS.

Now and the future

“At present, there are no direct mining projects underway, but projects are expected to begin in 2020. Drone operation and image-analysis techniques are currently being refined for industry,” he said. 

Besides his work with drones, Dr Clark also work in the fields of structural geology, remote sensing, and geospatial data analysis.

Self-help building project helps to change lives

UFS PhD student Anita Venter did not know it in the beginning, but her doctoral research would eventually change her life and the lives of many others. 

The research was whether South Africa’s housing policies were socially and culturally responsive to grassroots reality in informal settlements. Venter agreed her research approach might have raised a few eye brows, but it was a journey she holds had more benefits than failures. 

Green living
For her case studies, Venter looked at ‘Start Living Green’ as a concept and further examined the implementation models of Earthship Biotecture Academy in New Mexico and Central America and the Long Way Home non-profit organisation in Guatemala. 

These groups train people with no specialised construction skills in applying and managing environmentally sound self-help building projects. Furthermore, their primary objectives were not building-related, but people-centred, with an advocacy role to create social, environmental and educational change through utilising the building technologies. 

It resulted in Venter signing up for a course in Guatemala to get the skills to implement her case studies here at home in Bloemfontein. 

An experimental mud, straw and waste material structure in her back yard grew into similar houses built in informal settlements, through the transfer of knowledge of indigenous building methods.  

Are rickety corrugated iron shacks only alternative?

Her case studies, one in Freedom Square in the Mangaung Metro Municipality, highlighted, among others, baffling tenure insecurities and “tangible conflicts” entrenched between Westernised and African perspectives on home ownership.

Venter says her thesis, in essence, did not oppose existing housing strategies but did challenge the applicability of an economically inclined model as the most appropriate housing option for millions of households living in informal settlements. 

The main findings of the case studies were that self-help building technologies and skills transfer could make a significant contribution to addressing housing shortages in the country; in particular in geographical locations such as the Free State province and other rural areas.

Venter’s own words after her academic endeavour are insightful: “These grassroots individuals’ courage to engage with me in unknown territories, gave me hope in humanity and inherent strength to keep on pursuing our vision of transforming informal settlements into evolving indigenous neighbourhoods of choice instead of only being living spaces of last resort.”

Positive results 
The study has had many positive results. The City of Cape Town is now looking at new innovative building technologies as a result. Most importantly Venter's study will open further discussions that necessarily challenge the status quo views in housing development.
