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.

UFS hosts Nobel Laureate
2010-01-15

The University of the Free State (UFS) will host the 1991 Nobel Laureate in Chemistry, Prof. Richard Ernst from Switzerland, on its Main Campus in Bloemfontein from 22-26 January 2010.

Prof. Ernst’s visit to the UFS is part of an extended tour of South African higher education institutions and the National Research Foundation. His visit will coincide with the fourth presentation of the Cheese fondue that had previously been presented with great success in Europe.

The Cheese fondue concept is the brainchild of Prof. Hartmut Frank of the University of Bayreuth in Germany, who is currently a visiting fellow at the UFS Department of Chemistry.

This concept posits that technical advances alone are insufficient for an agreement to be reached on the minimum respect between the various groups and individuals within a society. It proposes that for this to be achieved there has to be a concurrent development of empathy and emotional synergy. In other words, there has to be spiritual acceptance and tolerance of the different cultural or religious ways of coming to terms with the deep-seated need for a spiritual home.

To this effect the UFS will host a Braai Workshop on Saturday, 23 January 2010 to promote this understanding, hence this year’s theme Justice, a matter of respect, ethics and empathy. The invitation to the workshop is open to the public and those who are interested should confirm their attendance with Ms Stefanie Naborn on 051 401 2531 before Monday, 18 January.

Prof. Ernst will present a paper on Justice – the Culture of Responsibility;  Prof. Patrizio Bianchi, the Rector of the University of Ferrara in Italy, will focus on the topic After the Global Crisis: Justice and Wellbeing – the Goals of Economy; while Judge of Appeal, Fritz Brand will talk about Justice – the South African reality.

Prof. Ernst, Prof. Bianchi and Judge Brand will also take part in a panel discussion, together with the Rector and Vice-Chancellor of the UFS Prof. Jonathan Jansen and Prof. Johan Henning, Dean of the UFS Faculty of Law.

Subsequent to that, Prof. Bianchi will present a lecture on the topic Globalisation, Agriculture and Industrial Development in the CR Swart Auditorium on the Main Campus on Monday, 25 January 2010 from 10h00 - 12h00. Prof. Ernst's lecture is from 12h30 - 14h30.
