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.”

UFS Department of Computer Science and Informatics motivates programming success among learners
2015-04-23

From Sentraal High School are from the left: Albert Dreyer (full marks, Grade 9); Corlé van der Walt (full marks, Grade 10); Janco Venter (full marks, Grade 10); Soné du Pisanie (full marks, Grade 10) en Handré Venter (Grade 9).

A group of learners from the Free State, who are taught at and by the University of the Free State’s Department of Computer Science and Informatics (under the Python project), came first in the Talent Search round of the South African Computer Olympiad (SACO).

According to Dr Anelize van Biljon, senior lecturer in the Department of Computer Science and Informatics, the Olympiad is presented in three main rounds: the Talent Search, the Application Olympiad, and the Programming Olympiad.

At the UFS’s Department of Computer Science and Informatics’ Python project, pupils from various schools in Bloemfontein attend programming classes where they are taught by staff and students of the department. These students are benefitted by the opportunity to transfer their knowledge to others. All the classes are free of charge.

Anelize explains: “The name was chosen because we use the Python programming language. It is a language with considerable appeal – not one of the fastest – which can be learnt relatively quickly, and which conforms to SACO requirements. The purpose of this programming is to implement algorithms (the learner is given a problem, makes a plan to solve it, and does the necessary programming). Thus, it is not about the looks of the programme, but about its effectiveness and speed.”
Anelize is the initialiser and co-ordinator of the Python project. "I started this project in 2010 in the Department of Computer Science and Informatics for learners from Grades 6 to 12 to encourage them to take the subject. These classes exposed them to something more than school work. I enjoy this kind of competitions and am also very involved with Maths Olympiads.

Achievements such as these are good advertisements for the Department of Computer Science and Informatics,” she said.
