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.

Get your dual-frequency card
2015-07-28

 Staff members and students, who are the owners/drivers of motor vehicles, are kindly requested to purchase the dual-frequency cards that replace their current student or personnel cards.

The dual-frequency cards can be read by the distance readers at the entrance gates. Card holders will no longer have to swipe their cards or stop; the boom will open automatically and card holders will be able to drive through.

Please note that this arrangement only applies to valid card holders entering the campus – on leaving the campus, they will again have to swipe their cards past the card readers.

This improves the traffic flow and prevent possible delays at the gates.

Pay for your card

Electronic fund transfers: Absa Bank: 1 570 8500 71, Ref: 1 413 07670 0198, OR pay the R65 at the UFS Cashiers, Thakaneng Bridge. 

Take your existing personnel or student card, together with proof of payment, to the UFS Card Division, Bloemfontein Campus, Thakaneng Bridge, to have your photo taken and your new dual-frequency card issued.

The UFS Cashiers will provide assistance between 09:00 and 14:30, and the UFS Card Division between 09:00 and 15:00.

Your new card

Permission to access specific UFS buildings or facilities linked to your existing card, will automatically be linked to the new card.

The new card is marked ‘dual’ on the back in the right, bottom corner.

The UFS would like to thank you for your cooperation in the successful implementation of access control on the UFS Bloemfontein Campus.
