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.

Six of our students on their way to Stanford Sophomore College
2014-08-21

The university hosted a send-off function for our students who are about to attend a three-week seminar at Stanford Sophomore College (SoCo).

Six Kovsie students were selected to attend the seminar at the Stanford SoCo in September 2014. This programme is an immersive learning experience where participants attend class meetings during the morning. Their afternoons include class activities, explorations of Stanford, field trips as well as organised events.

UFS students were invited to apply for one of six SoCo courses in February 2014. After months of apprehension, the successful Kovsie applicants were announced in May this year.

These outstanding Kovsie students and the courses they will attend are:

  • Sebabatso Makafane, Vuyisile Kubeka and Philip Kitsopoulos – New Millennium Mix: Crossings of Race and Culture;
  • Ulrich Kristen – Resistance Writings in Nazi Germany;
  • Kaylene Pillay – Ghost Stories: Why the Dead Return and What They Want From Us; and
  • Stephan Erasmus – Responses to the AIDS Epidemic.

During the farewell function, Rudi Buys: Dean of Student Affairs, handed the students their flight tickets and visas. This was followed by messages of support from Dr Lis Lange, Directorate for Institutional Research and Academic Planning, and Prof Neil Roos from the Centre for Africa Studies.

Prof Roos concluded the evening’s programme with some advice for these students. “Don’t go there and come back to copy the students and personalities you meet there. Go there and show your own characteristics to them.”

The six Kovsies will depart on 29 August and return home on 19 September 2014.
