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.

A journey into self-discovery
2011-08-17
Sandy Little

The launch of the film and book Africa meets Africa: Pathways through the Interior at our university was a huge success.

It forms part of the The Africa meets Africa Project that is known for making connections between knowledge systems in pursuit of learning. It integrates amongst others beadwork and weaving with mathematics.

The film takes one through the Free State and some parts of the Northern Cape. The two actors, Mr Lerato Mokhitli and Ms Sandy Little, are both art students at Kovsies. During the trip they reveal some historic events not known to all. Prof. Jonathan Jansen, Vice-Chancellor and Rector, said: “Our history is a lot more complex and interesting than current texts allow. Much of what happened laid the foundations for trauma, and triumph is poorly understood. More so, is the history of the ordinary.”

The film and book are funded by National Heritage Council and FirstRand. It was launched in other provinces, among them KwaZulu-Natal. The Africa meets Africa Project aims to use the book in the Free State and Northern Cape in the Further Education and Training (FET) phase for educators and university students.

Prof. Jansen furthermore said: “I would definitely recommend the book with some additions, such as representation of excluded cultures. This would include white ethnographic histories and cultures and the intersections across black/white, African/European histories. I would also make the subject history compulsory to ensure that children would be exposed to our complex history.”

Ms Moipone Kabaoe, a third-year B.Soc.Sc. student at UFS, said: “The film was very informative and clarified some things. I also believe the actors have actually grown from the experience and they did a great job.”

Mrs Anna Mokhitli was ecstatic at the launch, as any proud mother would be. “I knew they were working so hard, but I never thought it would be something this big,” she said. Ms Helene Smuts, Director of Africa meets Africa, said: “You cannot learn until you start with what you know. This is the journey we took; now you must take your own.”
