Green Futures Hub
Prof Wayne Truter, who is leading the Green Futures Hub at the UFS, highlights that mining and agriculture are important yet competing industries in South Africa. The hub aims to find sustainable ways for them to coexist.

Our earth is very resilient, and a green future is possible, but we must make changes. At the forefront of this mission is the Green Futures Hub, spearheaded by Prof Wayne Truter at the UFS. Prof Truter holds a PhD in Integrated Agricultural and Environmental Sciences, with more than 25 years of experience. He is a leader in the field of forage, pasture, and land regeneration – particularly those impacted by mining. 

The Green Futures Hub is a virtual platform that bridges academic research and industry gaps, aiming to solve real-world challenges with scientific insights. It is designed to showcase and integrate the research happening across various disciplines at the University of the Free State (UFS), making it accessible to industry and communities alike. “People often lose faith in academic institutions, thinking that the research done there has no practical value,” Prof Truter notes. “The Green Futures Hub aims to change that by making scientific findings accessible and relevant to daily life.” 

This platform offers a unique opportunity for industries to connect with researchers working on solutions related to climate change, sustainable agriculture, or environmental rehabilitation. “Our hub is a space where industries can come to us with their challenges, and we can offer solutions based on research,” Prof Truter explains. “It’s about creating real impact.” 

Collaboration and integration are central to the Green Futures Hub’s approach. “Through interdisciplinary collaboration and a commitment to environmental stewardship, we want to develop solutions to the complex development challenges related to ecosystems, agroecosystems, water resources, biodiversity, infrastructure, and communities,” says Prof Truter. 

One of the hub’s projects that is close to Prof Truter’s heart, is the future coexistence of mining and agriculture. Mining and agriculture are two important industries in South Africa, often competing for land. However, the hub seeks to bridge this gap by exploring how these industries can coexist sustainably.  

“The future coexistence of mining and agriculture is critical,” says Prof Truter. “While mining often uses the land intensively, they have the responsibility and capability to rehabilitate it for agricultural use, ensuring that it is as productive – if not more – than it was before. Farmers and miners have much to gain from each other,” he explains. “By partnering with industries, we can help rehabilitate the land that has been mined, and in turn, farmers can harness and bring back the productivity to that land with the financial inputs of mining companies.” 

Prof Truter also emphasises the importance of science communication. “We need to do better at communicating the value of the research we’re doing. Many times, industries don’t understand the significance of what we’re working on because it’s not explained in a way that resonates with them. The hub ensures that research findings are accessible, understandable, and applicable to real-world issues.”  

The Green Futures Hub is more than just a research platform; it is a testament to the power of collaboration between academia and industry. “We’re not just conducting research,” Prof Truter concludes, “we’re developing solutions.”

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.
