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.”

Summit programme

The third world summit in the International Year of Crystallography (in Africa) will be hosted by the UFS Department of Chemistry here on the Bloemfontein Campus. Prof André Roodt, Head of the Department of Chemistry, was elected as the President of the European Crystallographic Association in 2012. Earlier this year he unveiled the Max von Laue 'Plaque' in Posnan, Poland.

The Pan-African Meeting of the International Year of Crystallography consists of a congress and summit. The details are as follows:

Congress
12–15 October 2014
CR Swart Senate Hall, UFS Bloemfontein Campus

Summit
15–17 October 2014
CR Swart Senate Hall, UFS Bloemfontein Campus
Summit opening: Wednesday 15 October 2014 at 14:00 in the CR Swart Senate Hall

This event will be opened and attended by:
•    the UFS Rector and Vice-Rector – Profs Jonathan Jansen and Corli Witthuhn;
•    the acting Director-General of the Department of Science and Technology – Dr Thomas Auf der Heyde;
•    the acting CEO of the National Research Foundation – Dr Gansen Pillay;
•    the UNESCO Vice-Director for Science Extension – Dr Jean-Paul Ngome-Abiaga (Paris, France);
•    the representative of the Executive Committee for the International Union of Crystallography (IUCr) – Prof Santiago Garcia-Granda (Oviedo: Spain);
•    the marketing director of the IUCr – Prof Michele Zema (Pavia, Italy);
•    the President of the European Crystallographic Association (ECA) – Prof André Roodt, who will officially open the summit on Wednesday 15 October 2014 from 14:00–15:30.

Presenters from across Africa and Europe will deliver papers at this event which will be attended by more than 100 delegates from twenty-plus countries, including Spain, France, Italy, Croatia, Germany, Russia and India.

Numerous crystallographic research areas will be covered. This includes:
•    powder diffraction,
•    small molecule crystallography,
•    biological crystallography,
•    industrial crystallography,
•    surface crystallography,
as well as techniques such as
•    electron microscopy and
•    synchrotron work.

“At this event we hope to establish an African Crystallographic Association,” said Prof Roodt.

The United Nations declared 2014 as the International Year of Crystallography. It was recently officially opened at the UNESCO headquarters in Paris, France, by the Secretary General of the UN, Ban Ki-moon.

The International Year of Crystallography celebrates the centennial of the work of Max von Laue and the father and son, William Henry and William Laurence Bragg. More generally, it celebrates what crystallography can do for humanity – which proves to be a significant amount.
