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.

Former Kovsie wins Absa L’Atelier

A former Kovsie has taken top honours at the Absa L’Atelier Art Competition.

Elrie Joubert, who completed her master’s degree at the Department of Fine Arts in 2010, is the first Free Stater who has won the competition for young artists between 21 and 35. This puts her in the company of previous winners such as Penny Siopis and Diane Victor. As the overall winner, Joubert receives a cash prize of R110 000 and a six month stay at the Cité Internationale des Arts in Paris, France.

Her winning entry, Selective Unveiling, consists of a light-table with a private collection of miniature natural objects, a digital microscope used by the viewer to inspect the objects, as well as a projector that projects the microscope’s image directly on a screen.

“By making my private collection public, I expose myself to possible investigation and criticism,” says Joubert about her winning entry. “The process is, however, reversed when the viewer is also robbed of his/her ‘privacy’ in collecting images with the microscope, which are projected on a screen for other viewers to see.”

Joubert, who lectures in Drawing and History of Art of Graphic Design at the Midrand Graduate Institute’s Bloemfontein Campus, says the Absa L’Atelier is the biggest competition she has won thus far. In 2007 and 2010 she reached the final rounds of the SASOL New Signatures Art Competition.

Her advice to art students: “Keep on doing what you do, learn to handle criticism selectively, and above all, if you take no risks you’ll never win.”
