Back to the drawing board to save water
We’ve managed to damage nature’s ‘filter’ with air, ocean, and soil pollution, and by destroying wetlands.

Dr Cindé Greyling, a University of the Free State (UFS) DiMTEC (Disaster Management Training and Education Centre for Africa) alumni, studied drought mitigation with a strong focus on communicating important water-saving information. 

Can we run out of water?
Yes, and no, says Dr Greyling. “To our knowledge, water is not ‘leaking’ through our atmosphere. We have what we have, but that doesn’t mean we will have enough clean, fresh water forever. Nature has a magnificent way of purifying water through the water cycle. We, on the other hand, must use a lot of money and energy to purify water. Also, we’ve managed to damage nature’s ‘filter’ with air, ocean, and soil pollution, and by destroying wetlands. The other problem is a simple supply and demand scenario. More people will need more water, but not only that, population growth calls for industry development and increased food supplies – all of which require more water.”    

A war over water
Besides some Hollywood impressions, it is difficult to imagine a war over water, but it is possible. “Some experts are convinced that we are heading there, and others claim that such tensions already exist. Personally, I don’t favour these kinds of shock tactics (or truths) – social research has shown us that it rarely leads to behavioural changes. We can learn a lot from what was has been done in Cape Town. Although we all think people were bombarded with ‘Day-Zero’-scares, they were actually encouraged to adapt their behaviour with a communication campaign that hardly ever used the term ‘Day-Zero’. This approach mobilised citizens to reach record lows of water usage.” 

Adapt a new normal
Dr Greyling encourages the “new normal” set in motion by Capetonians. “Water consciousness is needed, even when the rain comes again. We’ve taken water for granted for too long. As consumers, we have the power to turn this situation around – drop for drop. Be aware about the amount of water you use, how you use it, and for what. Keep in mind that any wastage and pollution (of ‘dry’ things) also wastes and pollutes water. Generally, we need to behave better regarding consumption.”

Snow on our campuses
2012-08-07

Qwaqwa Campus
7 August 2012

Kovsies have been treated to the rather unusual sight of snow Tuesday, with the Qwaqwa Campus covered in a blanket of snow and the Bloemfontein Campus also dusted in white.

Snowflakes on the Bloemfontein Campus had people clicking away on their cameras and cellphones to capture this rare picture. The last time the City of Roses experienced this much snow was about six years ago.

Prof. Sue Walker, Head of Agricultural Meteorology in our Department of Soil, Crop & Climate Sciences, says the snowy weather over the Free State was caused by a cut-off low pressure system in association with a strong anticyclone ridging in behind the cold front.

“This draws a pool of very cold air, in the upper air, from the far southern ocean area in Antarctica driven by a strong southerly wind. This caused the freezing level, which is normally high in the atmosphere, to be lowered to the ground surface level, resulting in the snow.”

Prof. Walker says a little snow is forecast for Wednesday although rain can be expected before it clears and becomes sunny for the long weekend.
