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.

Colloquium focuses on protection of reproductive and sexual health in Africa

Our Department of Constitutional Law and Philosophy of Law of the Faculty of Law recently convened a two-day colloquium with the theme, ‘Strengthening protection of reproductive and sexual health in Africa through human rights’.

The colloquium built upon the work of the university’s LLM Programme in Reproductive and Sexual Rights, which trains law graduates to become specialists in reproductive and sexual health as human rights. The LLM Programme was first established in 2005. The colloquium brought together delegates from different professional backgrounds, including academia, health sciences and human-rights advocates from across the African region as well as from abroad.
 
Delegates addressed the theme of the colloquium in sessions  organised around the topics: HIV/Aids and human rights; sexual health and sexual rights; reproductive health and rights; abortion-related issues; and the intersection between cultural and religious perspectives and sexual and reproductive health and rights.
 
According to Prof. Charles Ngwena, Director of the LLM Programme, and co-convener of the colloquium together with Dr Ebenezer Durojaye, Postdoctoral Fellow in the Department of Constitutional Law at the UFS, the discussions flowing from the papers were to:
  • identify a persistent gap or challenge in the respect, protection and realisation of reproductive and/or sexual health as a human right under African human rights systems; and
  • advance arguments and suggestions that are aimed at addressing the gap or challenge and ultimately strengthening African human rights systems.
To address the regional dimension of the colloquium, the papers  delivered ultimately addressed selected reproductive and/or sexual health or right issues from a regional rather than a mere country perspective so that the experiences and challenges of the African region are captured.
