Water footprint important but misunderstood indicator
Water footprinting is the future of water conservation

The Water Footprint (WF) of a product, process or person provides an indication of how much fresh water is used, both direct and indirect, to produce a product, drive the process or lead a lifestyle. Although it is a very important indicator it is often misunderstood. Popular media contribute to this misunderstanding as they often use the WF to illustrate the large quantities of water used to produce a product without explaining what the footprint actually means.  

An example is a single kilogram of beef that has an average global WF 15 415 litres. This indeed sounds scary, but when one places it in context, the total WF includes 14 414 litres green water, 550 litres blue water and 451 litres grey water. Green water is the evapotranspiration of precipitation (rain), blue water is the fresh water from dams, rivers and underground sources, while grey water is the amount of fresh water required to dilute polluted water to acceptable levels.

According to Frikkie Maré, a lecturer at the Department of Agricultural Economics at the University of the Free State (UFS), the WF concept provides a new look at water conservation and sustainability. “Although the WF is not an indicator of sustainable water use, it is a useful tool to calculate total water demand and is used in the estimation of sustainability. Traditionally, water conservation was focused on the direct water use of individuals (time taken to shower, leaking taps etc.), but the WF now provides a tool to focus attention on total water demand.”

The Water Footprint Network assists individuals with this new trajectory on the water conservation front with the personal water footprint calculator that allows individuals globally to determine their personal water demand through their direct and indirect water usage. Maré believes this can cause the necessary paradigm shift in the aqua status quo by creating awareness among consumers on their total water demand.

With Water Week underway from 17-23 March 2018, UFS students and staff members are urged to make use of the personal water footprint calculator in order to become aware of the real importance of fresh water in our everyday lives.

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.
