Water-wise expert says Is there a solution to pollution
Next time you want to throw something away, think twice. Look for ways to reuse, recycle, or repurpose.

Dr Cindé Greyling completed her PhD in Disaster Management with DiMTEC (Disaster Management Training and Education Centre for Africa) at the University of the Free State (UFS). Built on prior studies and years of communication experience, she opted to study ways in which to communicate drought mitigation information. Part of the mitigation process included saving water and reducing pollution.

A practical approach

“Look, we are all here now. And we need to eat, live, work, survive, and ultimately thrive using our planet’s resources,” she says. “But I think we’ve become so fixated on thriving, that we don’t consider survival anymore. Of course, some people do! There are wonderful projects around the world aiming at more responsible consuming, ranging from pre-loved baby clothes, to water harvesting for individual dwellings and larger compounds.” However, she understands that people may get so overwhelmed by the vast pollution problem that they consider any of their own efforts as insignificant. “That is not true. Every single bit of plastic (or cloth, glass, iron, etc.) that is recycled or repurposed, and does not end up in a landfill, makes a difference.” And here is why…

The tip of the iceberg
“Whatever you are holding in your hand and aiming for the bin is much larger than what you see. Take a piece of paper, for example. A tree was planted – the process involved fossil fuels, water, fertiliser, time, wages, administration, etc. And many years of that! Once it was felled, the resource usages continued, and expanded to processing plants, wholesalers, retailers, and then you – who also used resources to acquire that piece of paper. Do you see how large the wastage is? The same is true for food waste … that rotten tomato you forgot in the fridge is a grave loss.”

“Whatever you are holding in your hand,
aiming for the bin, is much larger what
you see.”


Little by little  

Fortunately, all is not lost. “Respect stuff,” Dr Greyling says, “it is as simple as that. To survive, we must take from the resources that the Earth provides. Because we became clever, we were able to alter these elements to make, from high-rise buildings to tiny technology. But we simply cannot keep on taking and taking without giving back Start with giving respect. Next time you want to throw something away, think twice. Look for ways to reuse, recycle, or repurpose. Consider that the denim you are wearing possibly used up to 10 000 litres of water to produce.”

Researchers focus on parrots, poultry and phage therapy

Veterinary biotechnology focuses on microbial and molecular biological approaches to veterinary illnesses. The group working on veterinary biotechnology research at the University of the Free State (UFS) consists of two academic staff members, Prof Rob Bragg and Dr Charlotte Boucher, two post-doctoral fellows, Drs Chris Theron and Arina Hitzeroth, five PhD and three honours students.

The group has three research focus areas.

Dr Boucher says, “Our main focus area is infectious coryza in poultry, caused by the bacterium Avibacterium paragalliarum. The aim is the control of the disease, mainly through improvement of vaccines, understanding the immune response and improved biosecurity. A key objective is improving methods for serotyping; studying of selected surface antigens and investigating the influence recently discovered bacteriophages might have on virulence. We have co-operative projects with research groups in China, India and Israel.

“The second focus area is an expression system co-developed with the National Institute for Agronomic Research (INRA), France. The flagship project is the expression of the coat protein gene of the beak and feather disease virus, a disease affecting parrots, currently threatening the endangered Cape parrot. This system has led to the development of serological tests, currently under patenting. The application of this system has been extended to human-related diseases, with two interdisciplinary projects underway, co-working with Profs Muriel Meiring and Felicity Burt. Prof Meiring is working on diseases causing bleeding disorders, such as blood-clotting impairment, while Prof Burt is working on viral infections causing haemorrhagic (bleeding) disorders.

“We are also researching disease control in a post-antibiotic era, investigating the potential of phage-therapy by targeting and destroying pathogenic islands within a host, with reduced side-effects on the host itself.

“We have smaller projects, including an interdisciplinary project with Zoology, looking at the protein profile of amphibian (frog) secretions with the focus on antimicrobial activity, as these secretions assist with protecting amphibian skin against infections.”
