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.

Dr John Purchase, Chief Executive of the Agricultural Chamber of Commerce, was honoured as Kovsie Alumnus of the Year by the University of the Free State (UFS) during the annual Kovsie Alumni Awards Dinner on 2 September 2011. Dr Purchase and four other former Kovsies were honoured for exceptional achievements and contributions made to the UFS at this glittering event.

The well-known columnist Mr Willem Theron who writes columns for Beeld and Volksblad, was honoured with the Kovsie Ambassador Award. Another well-known Kovsie, the radio and television personality Mr Maurice Carpede was honoured with the Kovsie Cum Laude Award. Carpede shares this award with Mr Koert Pretorius, Chief Executive of Mediclinic South Africa, they received the award jointly. Mr Arie van der Bijl, retired Financial Director of the UFS, was honoured with the Alumnus Award for exceptional service delivered to the UFS.
 
Dr Purchase, who was unable to attend the award ceremony, expressed his appreciation in a pre-recorded message. He said that Kovsies taught him how to be a leader. Theron, a marketer for the Kovsie Alumni Trust who received the Centenary Medal from the UFS in 2004, said in his acknowledgement speech that he feels humbled by this award. He said Kovsies became both his home and his family.
 
Both Carpede and Pretorius mentioned the impact Kovsies had on their lives. Carpede said he became a Kovsie in the years of transition, a time when words like “whites only” were printed on some doors, but despite all of that, he learnt that not all whites were bad. Pretorius, who was honoured for his contribution to private healthcare in the country, said that Kovsies were the key that unlocked several doors for him.
