Did you know that one can photograph a plant so clearly from a distance that it is likely to detect the health of its leaves? Or can you contemplate the possibility of taking a photograph of three similar-looking rocks, being able to distinguish them from each other due to spectral properties associated with their internal mineral content?

This and other drone-based geological imaging are made possible by the Merensky group for Aerial Geological Image Classification (MAGIC) at the University of the Free State (UFS).

Recently (24 March 2022), the President of the Hans Merensky Foundation (HMF), Dr Khotso Mokhele, signed a R11 million five-year research grant agreement with the UFS. Merensky research projects are currently limited to three South African universities – Stellenbosch University (for forestry research), the University of Pretoria (for avocados), and now the UFS.

Demonstration and application

Dr Mokhele, who is also the former Chancellor of the UFS, states: “When I walked into the MAGIC Lab, I knew that something special was going to happen here. What we are launching today will become a world-class and world-leading facility.”

According to him, Dr Hans Merensky, whose legacy is facilitated by the foundation, was one of the most influential geologists in South Africa. He discovered, among others, deposits of gold, platinum, diamonds, phosphates, and vermiculite. After several decades of operating in the geological sciences and with his knowledge of soil health, Merensky became a conservationist of note and played a key role in the establishment of the country’s agricultural practices.

“The main objective of the Hans Merensky Foundation is to promote and assist in the development of the resources of South Africa and neighbouring territories – particularly such natural resources as soil, water, flora, and fauna – and to promote the health and welfare of the inhabitants; more specifically, through research, experimentation, and demonstration and through the correlation and application of scientific knowledge.” 

“You have to take the knowledge and translate it into demonstration of what that knowledge can do, and then apply it,” says Dr Mokhele.

The grant is also evidence of Dr Merensky’s generosity. He is well quoted saying: “This country has given to me so much, that I am only too happy to be allowed to help it to develop in some way, and I am grateful to be able to give back to it a fraction of what it has given to me.” 

Next generation of scientists

The Rector and Vice-Chancellor of the UFS, Prof Francis Petersen, said at the signing ceremony that this is an exciting project. “For us as a university, research and the development of the next generation of scientists are critical. This is part of our mandate. This project is one of those catalysts for the development of what the mandate is all about – research output, capacity building, and impact through our students and our research in a broader society.”

He thanked Dr Mokhele for facilitating the project and introducing the UFS to the Hans Merensky Foundation, having the confidence that the university has the capacity to deliver.  

“For Dr Mokhele, it is all about the science. To a certain extent, his driving force was to use science to make a difference in the lives of people,” says Prof Petersen. 

He continues: “The institution is highly committed to this project and will make sure that it receives the maximum support to make it a success.”

The grant has been allocated to MAGIC and funds will be used to support research programmes. “This includes student bursaries, staff salaries, capital expenditure acquisitions such as high-performance computers, as well as the drones that the project makes use of,” states Dr Martin Clark, Lecturer in the Department of Geology.

According to him, the group aims to develop drone-based geological imaging in South Africa, with specific attention to mineral and groundwater exploration endeavours.

Impacting society 
 
“What makes me excited about this project is how the research impacts society.  This includes developing geological imaging capacity in South African geologists with a 4IR skillset, ensuring that they remain competitive in a global market,” says Dr Clark.

He is also of the opinion that many industries will be able to see for themselves how this technology can improve their businesses. “Drone-based geological imaging can be quicker, cheaper, and safer for collecting much of the initial information that informs more expensive exploration processes, such as drilling. Additionally, it is non-invasive, and has little to no impact on the environment during data collection. Drones can also, in terms of safety, collect data from unstable rock walls – historically, geologists would have to take those measurements themselves, with rock falls resulting in a significant number of deaths every year.”

Recent research

Dr Clark says drone-based imaging has supported research initiatives in the Vredefort Dome. “Using drone-collected high-resolution images of meteorite impact melt rocks, along with field observations of how much and where foreign rock components were contained within (clasts), we could make a case for turbulent flow in the migration of impact melt material within the deep crust.”
 
He adds that three papers are currently underway, each predicated on drone imagery that enables new insights into geological processes or the ability to digitally translate geological information inside and outside the classroom.

The growing research group, with Dr Clark as the principal investigator, consists of one PhD student, two master’s students, and two honours students, with several postdoctoral research fellows to follow soon. 

The difference

Although several universities in the country have started using drones, the UFS has significant support to grow drone applications. With assets such as the high-performance computing cluster, very large drone-borne datasets can be resolved in record time.  

“The UFS also has a wealth of world-class researchers focused on topics such as farming and environmental management, who will be able to benefit from the drone infrastructure being established on campus. We are aiming to be the go-to geological drone imaging group in South Africa,” he says. 




About mineral and groundwater exploration


Dr Martin Clark explains that drones can carry several types of cameras, from regular photographic cameras that capture photos as we know it, to thermal cameras showing differences in hot and cold bodies, to spectral cameras capturing beyond what our eyes can see into other portions of the electromagnetic spectrum.  The MAGIC group mainly uses regular and spectral cameras for their applications. 

He says with mineral exploration, a high-resolution understanding of the geometry of rock bodies enables us to better identify where more costly mineral exploration techniques (e.g., drilling) should go.  This process allows for a better understanding of how geological areas have developed from a structural perspective – in essence, from where and how rocks have been displaced and deformed, and by association, the mineral deposits contained within.

“In terms of groundwater exploration, regular cameras are used to understand where rocks are fractured, where specific groundwater-influencing lithological bodies are located, and how they are orientated.” 

Dr Clark continues: “With spectral cameras, we can perceive the level of access that surface plants have to water resources. It is also possible to spot the distribution of plant types associated with, or strongly dependent on, available near-surface groundwater resources.  By using spectral data, which was historically collected from satellites, we can understand how areas of land have been affected by growing, shrinking, or shifting underground bodies of water.”

Institutional research culture a precondition for research capacity building and excellence
2004-11-16

A lecture presented by Dr. Andrew M. Kaniki at the University of the Free State Recognition Function for research excellence

16 November 2004
The Vice Chancellor, Prof. Frederick Fourie
Deputy Vice Chancellors, Deans
Awardees
Colleagues and ladies and gentlemen

It is a great pleasure to be here at the University of the Free State. I am particularly honoured to have been invited to present this lecture at the First Annual Recognition Function for Research Excellence to honour researchers who have excelled in their respective fields of expertise. I would like to sincerely thank the office of the Director of Research and Development (Professor Swanepol), and in particular Mr. Aldo Stroebel for facilitating the invitation to this celebration.

I would like to congratulate you (the UFS) for institutionalizing “celebration of research excellence”, which as I will argue in this lecture is one of the key characteristics of institutional research culture that supports research capacity building and sustains research excellence.

Allow me to also take this opportunity to congratulate the University of the Free State for clocking 100 years of existence.

Ahmed Bawa and Johan Mouton (2000) in their chapter entitled Research, in the book: Transformation in higher education: global pressures and local realities in South Africa (ed. N. Cloete et. al Pretoria: CHET. 296-333) have argued that “…the sources of productivity and competitiveness [in the knowledge society and global economy] are increasingly dependent on [quality] knowledge and information being applied to productivity”. The quality knowledge they refer to here is research output or research products and the research process, which (research) as defined by the [OECD] Frascati Manual (2002: 30) is:

“…creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of man, culture and society, and the use of this stock of knowledge to devise new applications”

The South African Government has set itself the objective of transforming South Africa into a knowledge society that competes effectively in the global system. A knowledge society requires appropriate numbers of educated and skilled people to create quality new knowledge and to translate the knowledge in innovative ways. To this end a number of policies and strategies like the Human Resource Development [HRD] Strategy for South Africa, the National Plan for Higher Education (NPHE) and the South Africa’s Research and Development [R&D] Strategy, have highlighted human resource development and the concomitant scarce skills development as critical for wealth creation in the context of globalization. The key mission of the HRD Strategy for instance is:

To maximize the potential of the people of South Africa, through the acquisition of knowledge and skills, to work productively and competitively in order to achieve a rising quality of life for all, and to set in place an operational plan, together with the necessary institutional arrangements, to achieve this.

The R&D Strategy emphasizes that maximum effort must be exerted to train the necessary numbers of our people in all fields required for development, running and management of modern economies. Higher education institutions like the University of the Free State have a key role to play in this process, because whatever form or shape a university takes, it is expected to conduct research (quality research); teach (quality teaching – and good graduates); and contribute to the development of its community! Thus the NPHE states that the role of higher education in a knowledge-driven world is threefold:

Human resource development;

High-level skills training and

Production, acquisition and application of knowledge.

Quality research output or knowledge which as argued is critical in determining the degree of competitiveness of a country in the knowledge economy is dependent upon quality research (process). Both the process of producing quality research and its utilization cannot and does not happen in a vacuum. It requires an environment that facilitates the production of new knowledge, its utilization and renewal. It requires skilled persons that can produce new knowledge and facilitate the production of new skills for quality knowledge production. Such an environment or in essence a university must have the culture that supports research activity. Institution research culture (that is a conducive and enabling institutional research culture) is a precondition to research capacity building. Without an institutional research culture that facilitates the development and nurturing of new young researchers it is difficult, if not impossible for a university to effectively and efficiently generate new and more quality researchers. Institutional research culture is also necessary to sustain quality research and quality research output or research excellence. It facilitates the development and sustenance of the institutional and people capacities required to do research produce quality research and generally attain research excellence!

We do recognize that the patterns of information and knowledge seeking, and knowledge generation vary among field or disciplines. For example, we know that in the humanities knowledge workers often work individually, and not as collaboratively as do those of the sciences, they all however, require supportive environments – institutional research culture to achieve and sustain research excellence. An institution does not simply attain a supportive research culture, but as Patricia Clements (English Department, University of Alberta, Edmonton) in her presentation Growing a research culture argues, research culture has to be grown [and maintained]. It unifies all natural and engineering scientists; medical researchers, humanists, and social scientists.

I therefore am of the view that Institutional Research Culture is critical to research capacity building and research excellence. I therefore want to spend a few minutes looking at the characteristics of research culture. To be effective, institutional research culture has grown and sustained not only at the institutional level, but also at the faculty, school and departmental levels of any university.

What is Research Culture?

In the process of researching on institutional research culture I identified several characteristics. Many of these overlap in some way. I want to deal with some of these characteristics; some in a little more detail while others simply cursorily. In the process what we should be asking ourselves is the extent to which an institution, like the University of the Free State, and its faculties, individually and severally, is growing and or sustaining this culture.

Institutional Research Strategy: As a plan of action or guide for a course of action, the institutional research strategy must spell out research goals that a university wants to achieve. It must be a prescription of what the university needs to be done with respect to research. As a strategy it is neither an independent activity nor an end in itself, but a component part and operationalization of the university policy or mission. ( Related to this is the Establishment of Institutional research policies)

Includes and makes public the targets, e.g. achieve so many rated scientists and make sure that every year we have so many SAPSE publications. That way people keep an eye on research agendas of the university and nation.

The UFS is obviously on its way, having launched its own Research strategy (A Strategic framework for the development of research at the University of the Free Sate. August 2003). Note that this strategy refers specifically to the “Culture of research” Fig 1

A set of administrative practices to support and encourage research. Patricia Clements (English Department, University of Alberta, Edmonton) in her presentation Growing a research culture argues that that research activity and output within the her Faculty (Arts) were very low and, in spite of the numbers of staff, with no Associate Dean for Research in the Faculty as though they had accepted that research belonged to Medicine and Science and Engineering, and teaching, separated from inquiry, belonged to the Arts. With the change in the thinking about research and development of research culture, it became clear that there was a major role for research support in a faculty her size (now about 360 full time continuing academic staff). The faculty developed a support system for research and began to address the SSHRC issues.

Reduce the bureaucracy system and micromanagement of research! This however, also implies that there is capacity and policies and procedure to manage and guide research processes

Establishment of Intellectual Property regulations and assistance

Research ethics policy and safeguarding by research administration

Focused, applied and suitable nature of the delivery mode (an institution open to new methodologies for conducting research

Programmes suited both full and part-time study particularly at graduate level (Mainly at Faculty/school and department level, and depending on what’s manageable)

Hiring senior academics to engage in, teach on and supervise postgraduate students to facilitate exchange of and transfer ideas and most importantly mentorship especially in view of declining numbers of researchers in particular fields

Quality instruction and facilitation in learning about research processes

A high retention rate of students maintained by the supportive and challenging learning environment and the use of online facilities to support collaboration and in-class learning

Availability of research grants: and awareness of sourcing funds from external sources like the National Research Foundation; Water Research Commission; Medical Research Council, private philanthropies and others outside the country. For example an institution should be able to assess how much of the slice the available funds (NRF etc) its able acquire and possibly top slice from institutional budget.

Adequacy of the financial reward system to encourage university staff members to do research (General Celebration of achievement for research excellence and achievement. This ranges form Annual reports mention; celebratory dinner. At Alberta researchers were given lapels. I don’t know of any academic who do not feel a sense of achievement to get into print or recognised. Access to research facilities within and outside the institution

Provision of infrastructure to support university-based research (e.g. equipment, admin support, etc.) – but also awareness of publicly funded and available research facilities and equipment!

Internet connectivity and changes in the bandwidth of the internet to download articles

Subscription to related bodies by the library so that researcher can download articles

Facilities and resources to attend international conferences to keep one updated

Number of visiting professors/speakers targeting senior scholars and invite them to lunch to ask them to participate and to encourage their best graduate students to do so within the institution and across institutions

Research training seminars for research students including young academics

Participation of staff/students in delivering research papers to national and international conferences

Establishment of research groups to provide interaction frameworks to achieve critical mass of research-active staff

Facilitation for more research time: Targeting new scholars and giving them reduced teaching loads in their first year or two for the purpose of developing their research programs. For the purpose of helping new colleagues to see the shape of South African research support, personalizing it, and creating research community

Take research to the community and argue its necessity, and utility

And, finally celebrating excellence. We must recognize achievement - parties and public recognition for colleagues who achieve splendid things in their research.

In conclusion, I want to reemphasize that research culture has to be grown it does not simply exist in an institution. If it is grown it needs to be nourished, nurtured and sustained. An institution cannot simply leave on borrowed reputation and expect to remain research excellent. It is on this basis that instruments like the National Research Foundation rating system recognizes excellence within a given period of time and not necessarily for a life time! This it is believed encourages continued research excellence.
