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.”

Breeding of unique game requires a balance between conservation and sustainable use
2014-05-20

 

Game bred for qualities such as unconventional hair colour or horn quality, may on the long term have unexpected consequences for biodiversity and game farming.

This is according to the inaugural lecture of Prof Paul Grobler from the Department of Genetics at the University of the Free State (UFS).

Prof Grobler feels that the consequences of selective breeding should be examined carefully, as there is currently much speculation on the subject without sound scientific information to back it.

“At the moment, colour variation invokes much interest among game farmers and breeders. Unusual colour variants are already available in different game species. These unusual animals usually fetch much higher prices at auctions compared to prices for the ‘normal’ individuals of the species.”

Examples of these unusual variants are springbuck being bred in white, black or copper colours, the black-backed or ‘saddleback’ impala, and the gold-coloured and royal wildebeest.

A black-backed impala was recently sold for R5,7 million.

“Based on genetic theory, good reason exists why these practices need to be monitored, but one should also take care not to make the assumption that selective breeding will inevitably lead to problems,” warns Prof Grobler.

Grobler says that negative characteristics in a species can sometimes unwittingly be expressed during the selection process for a unique colour. “It is seen, for example, in purebred dogs where the breeding of a new race sometimes brings underlying genetic deviations in the species to the front.” He also believes that some of these animals may not be able to adapt to changing environmental conditions.

“However, one should also look at the positive side: because of the good demand for game, including unusual variants, there is much more game in South Africa today than in many decades. Balance should be found between the aims of conservation and the sustainable utilisation of game.”

Research at the UFS’s Department of Genetics is now trying to establish the genetic effects of intensive game breeding and predict the impact on biodiversity.
