Mountain research Maloti-Drakensberg
Tucked in the foothills of the Maloti-Drakensberg Mountains is the Qwaqwa Campus of the University of the Free State (UFS), the home of the Afromontane Research Unit (ARU).

Mountains and highlands have always played an important role in the history of mankind. They produce economically essential goods and services (such as fresh water), host unique biodiversity, and offer unique recreational and tourism opportunities. Mountains are also a place for spiritual sanctuaries and are often used for journeys of self-reflection through pilgrimage.

In addition to these ‘feel good’ benefits, mountains are hazardous areas for communities and infrastructure and are vulnerable to natural disasters. Mountainous areas are also often natural borders defining geopolitical entities, but in the process splitting and marginalising communities, creating economic shadow zones and sometimes becoming highly militarised areas. 

“Southern African mountains provide enormous opportunities for holistic research as social-ecological systems, with some of the most interesting and least academically explored environments on Earth,” said Dr Vincent Clark, Director: Afromontane Research Unit (ARU) on the UFS Qwaqwa Campus

The Afromontane Research Unit
The Qwaqwa Campus of the University of the Free State (UFS) is the home of the ARU, a multidisciplinary flagship group addressing the largely under-researched mountainous landscapes of southern Africa. 

Research in the ARU is promoted around three broad themes to foster inter- and multidisciplinary discourse: (1) conservation and sustainable use of Afromontane biodiversity; (2) sustainable futures for the people of the Afromontane; and (3) living and doing business in the Afromontane –  with the intention of creating a sustainability science hub to bring the three themes into the ambit of solution-oriented transdisciplinary research, centred in the sustainable development goals and sustainability research in general. 

Continental leader
To achieve its vision of becoming a continental leader in African mountain research, the ARU is positioning itself as a mountain-knowledge generator and interchange by developing key relationships locally and internationally. The most valuable local partnership is with the South African Environmental Observation Network (SAEON), with which the ARU will be sharing a Research Chair. 

The Chair will contain strong expertise in the Social Sciences to complement the existing strong Natural Science element in both the ARU and SAEON. The Sustainability Science component is being built through inter alia a mutually-reinforcing relationship with the University of Tokyo and United Nations University, Tokyo. 

The future
“In tandem with robust collaborations to achieve its goals, the ARU provides an envious capacity-building programme for its early career campus academics, postdoctoral and postgraduate students,” said Dr Clark. 

The scale of influence of the ARU is prioritised as ‘back yard first’, namely solution-oriented research that benefits Phuthaditjhaba, Qwaqwa, Golden Gate Highlands National Park and Royal Natal National Park. Thereafter, the ARU seeks to facilitate research that encourages the sustainable development of the Maloti-Drakensberg as a unique social-ecological system in Africa, and from there facilitate research in the intellectual vacuum that is the southern African mountains. With time, the ARU aims to take the intellectual lead as an Africa-based leader in African mountain research. The success of this will depend on how carefully the development of human infrastructure can be balanced with that of the myriad opportunities presented.”

With a diverse and motivated team, situated in one of the most attractive environments in Africa, the ARU is here to change the way we think about African mountains and what they mean for us all.

H.E.S.S. (High Energy Stereoscopic System) scientists publically revealed their latest galactic discovery in the international science journal, Nature, on 16 March 2016. These scientists were able to pinpoint the most powerful source of cosmic radiation – which, up to now, remained a mystery.

Part of this team of scientists are Prof Pieter Meintjes and Dr Brian van Soelen, both in the University of the Free State (UFS) Department of Physics. Dr Van Soelen explains that they have discovered a proton PeVatron – a source that can accelerate protons up to energies of ~1 PeV (10^15 eV) – at the centre of the Milky Way. The supermassive black hole called Sagittarius A has been identified as the most plausible source of this unprecedented acceleration of protons.

The protons are accelerated to Very High Energy (VHE) gamma rays. The energy of these protons are 100 times larger than those achieved by the Large Hadron Collider at CERN (the European Organization for Nuclear Research).

According to Dr Van Soelen, the fact that this research has been published in Nature demonstrates the importance and pioneering nature of the research conducted by H.E.S.S. The H.E.S.S. observatory – operational in Namibia – is a collaboration between 42 scientific institutions in 12 countries.

In 2006, H.E.S.S. was awarded the Descartes Prize of the European Commission – the highest recognition for collaborative research – and in 2010 the prestigious Rossi Prize of the American Astronomical Society. The extent of the observatory’s significance places it among the ranks of the Hubble Space Telescope and the telescopes of the European Southern Observatory in Chile.

“The next generation VHE gamma-ray telescope,” Dr Van Soelen says, “will be the Cherenkov Telescope Array (CTA), which is currently in the design and development stage.” Both Dr Van Soelen and Prof Meintjes are part of this project as well.

H.E.S.S. has issued a complete statement about the paper published in Nature.
