Dr Ismari van der Merwe was instrumental in establishing the new Department of Sustainable Food Systems and Development.

Dr Ismari van der Merwe believes that by forging strong relationships, women can affect virtually every aspect of their students' lives, teaching them vital life lessons that will help them succeed beyond term papers and standardised tests. 

She states that it is not always easy to change a student's life, so it takes a great teacher to do so. “You, as a teacher, have a very significant, lifelong impact on all your students. This impact involves not only the teaching of particular academic skills, but as importantly, the fostering of student self-esteem.”

“Reinforcing self-esteem in the classroom is associated with increased motivation and learning,” she says.

Dr Van der Merwe is Lecturer and Programme Director in the Department of Sustainable Food Systems and Development at the University of the Free State (UFS).

On 11 February – International Day of Women and Girls in Science – the UFS is celebrating her not only for the impact she has on her students, but also for being instrumental in establishing the new Department of Sustainable Food Systems and Development, putting the UFS on the international forefront.

A sustainable food system

“We want our students to be part of a sustainable food system that provides healthy food that meets food needs, while maintaining healthy ecosystems that can also provide food for generations to come, with minimal negative impact to the environment,” she says. 

“The right to food is a fundamental human right.”

Dr Van der Merwe believes that a healthy personal food system and how it is managed is now more critical than ever before. 

Her current work involves managing the five main food-related values of taste, health, cost, time, and social relationships, as well as other less prominent values of symbolism, ethics, variety, safety, waste, and quality within these personal food systems. She feels the prominence of these values varies among us as well as across our eating situations. “More research on this will be fascinating,” says Dr Van der Merwe. 

A male-dominated field

On the role of women in science, Dr Van der Merwe says it is often considered a male-dominated field. “According to United Nations data, less than 30% of scientific researchers worldwide are women,” she states.

Telling her story about becoming a scientist, she says that science chose her. “Many scientists have reported that their interest and curiosity in science or the natural world started in early childhood.”

“I started as a teacher and ended up working for the Agricultural Research Council, where I was responsible for a research programme on dry beans and started a small-scale research factory.”

“Later when we moved to Bloemfontein, I joined the UFS. Here I am privileged to be able to do research and teach. Science chose me as part of my life journey, and I never looked back.”

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.
