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.

Reclassification of giraffe status pivotal in public action, says UFS researcher

Great news for those who care about the conservation of giraffes is today’s (8 December 2016) announcement by the International Union for the Conservation of Nature (IUCN) that giraffes are now classified as ‘Vulnerable’. The species, formerly classified as ‘Least Concern’ on the IUCN Red List — an index on the likelihood of extinction of animals worldwide — is threatened with extinction.

“Until recently, few people were aware of the situation facing giraffes. It is time to show the world giraffe numbers are in danger. This reclassification by the IUCN is pivotal to get the public to stand up and take action for giraffes,” said Dr Francois Deacon, specialised researcher in the Department of Animal, Wildlife, and Grassland Sciences at the University of the Free State (UFS).

Research is essential to develop effective conservation plans for a species

Key to this announcement was the status report submitted by Dr Deacon. He was the lead author responsible for the submission of the Southern African Giraffe subspecies (Giraffa camelopardalis giraffa) status report that was part of the larger species report submitted for review by the (IUCN). The UFS has been doing many research projects in the past couple of years on giraffe-related issues and topics to address this problem.

The UFS is one of only a few universities in Africa that is committed to studying giraffes to ensure the conservation of this species for generations to come.

“The reclassification of giraffes to ‘Vulnerable’
status, by the IUCN, is pivotal to get the public
to stand up and take action for giraffes.”

A 40% decline in the giraffe population over the past two decades is proof that the longnecks are officially in trouble. According to Dr Deacon, this rate of decline is faster than that of the elephant or rhino. The main reasons for the devastating decline are habitat loss, civil unrest and illegal hunting.

Dr Deacon, pioneer in the use of GPS technology to study giraffes and their natural habitat, said “This vulnerability clearly stipulates we are quickly losing grip on our last few natural populations”. He and a team of researchers at the UFS in South Africa are leading various research and conservation projects to help save the last remaining giraffes in Africa.

Giraffes moved from ‘least concern’ to ‘vulnerable’ on the Red List

The IUCN, a health check for our planet, is the highest level at which decision-makers can prove how many species (fauna or flora) are surviving or not. The update from ‘Least Concern’ to ‘Vulnerable’ on the Red List was released at the 13th Conference of the Parties to the Convention on Biological Diversity in Cancun, Mexico.

A wildlife documentary, Last of the Longnecks clearly shows how the number of giraffes has plummeted in the past two decades from 154 000 to fewer than 98 000 today — with numbers of some giraffes, such as Kenya’s reticulated giraffe, declining by as much as 80%.
