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.

The University of the Free State (UFS) boasts three hockey players who have been included in the SA u/21 teams that will take part in the interprovincial hockey tournament for seniors during August 2012.

The two Protea players, Izelle Lategang (a second-year B.A. student), and Tanya Brits (a first-year B.A. Arts student), who toured with the Proteas in Europe during May and June this year, are the pride of the university. A further honour for the Kovsie Hockey Club was the naming of Izelle as captain of the SA u/21 team. Nicol Walraven from Eunice Girls’ School is also in the team. Nicol is the sister of Brett Walraven, who plays for both the Kovsies’ men’s first team and the Free State.

For the first time in more than 30 years, the university’s men’s hockey team has produced a SA u/21 player. Richard Pautz, a first-year B.A. student, played for the SA Schools team two years ago and made a return to hockey when he became a student of the UFS this year.

Two other students from this university, Cornelle Botha and Niel Roode, were in the final training group.
