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.

Kovsie athletes set the world alight
2009-08-05

Kovsie athletes Johan Cronjé, Thuso Mpuang and Kagisho Kumbane recently left for Berlin to participate in the World Senior Athletics Championships that will take place from 15-23 August 2009. It is an extraordinary achievement for the University of the Free State (UFS) that three of its athletes were included in the South African senior group that will participate in the world athletics championships in Berlin.

Johan will participate in the 1 500 m. Thuso, who earlier this year won a bronze medal in the 200 m at the World Student Games that were held in Belgrade, Serbia with a time of 20,69 seconds, will again participate in the 200 m at the championships in Berlin. Together with Kagisho he is also included in the South African relay team that will participate in the 4 x 100 m relay at these championships. Both Thuso and Kagisho were included in the South African team that ended third in the 4 x 100 m relay in Belgrade.

Kagisho also participated in the World Student Games in Belgrade, Serbia and progressed to the third round in the 100 m. Boy Soke, also a Kovsie athlete, ended in ninth place in the 5 000 m finals in Belgrade.

Windy Jonas, also from Kovsies, has left for Mauritius where he will participate in the Africa Junior Championships that will take place from 30 July to 3 August.
