The Ruforum Wool project strives to ensure sustainable growth for communal wool farmers in the Free State by enabling them to compete in wool quality with commercial wool farmers through end-to-end development of the wool value chain. In this project, small-scale wool farmers and community members are identified and invited to take part in the project where they learn various skills in each component of the wool value chain. As a result, production by the communal wool growers is transformed from an underachieving enterprise to a profitable, sustainable, and renewable venture that will enhance the livelihoods of wool producers in the community.  

An interview with Carien Denner, Project Manager in the Department of Consumer Science at the University of the Free State (UFS), revealed that there is more to this woman who is working hard to enhance the livelihoods of communities. 

Please tell us about yourself: Who are you, and what do you do? 

“I am involved in the Community Gardens Food Security project, as well as the Ruforum Wool project. With the latter project, I serve on the management team that was established to commercialise wool production in the communal areas of the province by developing strategies to overcome the various challenges faced by these growers.”

Is there a woman who inspires you and who you would like to celebrate this Women’s Month? Why?

“My mother, a teacher for more than 43 years, epitomises my idea of a dynamic woman being kind, encouraging, truthful, fun, strong, selfless, and brave through everything that life has thrown at her. I believe that a mother’s love and sacrifices are what makes us as women dynamic – each in her own right.”

What are some of the challenges you have faced in your life that have made you a better woman?

“When my dad passed away (I was 12 years old), I saw my mom being an ironwoman who never gave up and never got tired. Instead, she showed us what courage looks like and set an amazing example of strength and perseverance for my brother and me.”

What advice would you give to the 15-year-old you?

“This is not a good question to ask someone in the middle of a pandemic! I would tell myself to appreciate every day for what it is and not to stress about the future too much.  

What would you say makes you a champion woman [of the UFS]?

“I think a champion woman is someone who – especially during these trying times – supports, empowers, and uplifts her fellow man. The Ruforum Wool project and everyone who is involved in it is doing precisely that. We need to empower, uplift, and encourage our emerging farmers to restore dignity and ensure sustainability in agriculture, food production, and their general participation in the economy. Communities surrounding them are equally in need of sustainable employment opportunities where valuable skills can be learned in order to provide for themselves and their families. This is what we strive to do to make a meaningful difference through our efforts.”

NRF grants of millions for Kovsie professors

Two professors received research grants from the National Research Foundation (NRF). The money will be used for the purchase of equipment to add more value to their research and take the university further in specific research fields.

Prof Martin Ntwaeaborwa from the Department of Physics has received a R10 million award, following a successful application to the National Nanotechnology Equipment Programme (NNEP) of the NRF for a high-resolution field emission scanning electron microscope (SEM) with integrated cathodoluminescence (CL) and energy dispersive X-ray spectrometers (EDS).

Prof Bennie Viljoen from the Department of Microbial, Biochemical and Food Biotechnology has also been awarded R1,171 million, following a successful application to the Research Infrastructure Support Programme (RISP) for the purchase of a LECO CHN628 Series Elemental Analyser with a Sulphur add-on module.

Prof Ntwaeaborwa says the SEM-CL-EDS’ state-of-the art equipment combines three different techniques in one and it is capable of analysing a variety of materials ranging from bulk to individual nanoparticles. This combination is the first of its kind in Africa. This equipment is specifically designed for nanotechnology and can analyse particles as small as 5nm in diameter, a scale which the old tungsten SEM at the Centre of Microscopy cannot achieve.

The equipment will be used to simultaneously analyse the shapes and sizes of submicron particles, chemical composition and cathodoluminescence properties of materials. The SEM-CL-EDS is a multi-user facility and it will be used for multi- and interdisciplinary research involving physics, chemistry, materials science, life sciences and geological sciences. It will be housed at the Centre of Microscopy.
“I have no doubt that this equipment is going to give our university a great leap forward in research in the fields of electron microscopy and cathodoluminescence,” Prof Ntwaeaborwa said.

Prof Viljoen says the analyser is used to determine nitrogen, carbon/nitrogen, and carbon/hydrogen/nitrogen in organic matrices. The instrument utilises a combustion technique and provides a result within 4,5 minutes for all the elements being determined. In addition to the above, the machine also offers a sulphur add-on module which provides sulphur analysis for any element combination. The CHN 628 S module is specifically designed to determine the sulphur content in a wide variety of organic materials such as coal and fuel oils, as well as some inorganic materials such as soil, cement and limestone.

The necessity of environmental protection has stimulated the development of various methods, allowing the determination of different pollutants in the natural environment, including methods for determining inorganic nitrogen ions, carbon and sulphur. Many of the methods used so far have proven insufficiently sensitive, selective or inaccurate. The availability of the LECO analyser in a research programme on environmental pollution/ food security will facilitate accurate and rapid quantification of these elements. Ions in water, waste water, air, food products and other complex matrix samples have become a major problem and studies are showing that these pollutants are likely to cause severe declines in native plant communities and eventually food security.

“With the addition of the analyser, we will be able to identify these polluted areas, including air, water and land pollution, in an attempt to enhance food security,” Viljoen said. “Excess levels of nitrogen and phosphorous wreaking havoc on human health and food security, will be investigated.”
