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.

Prof. Jonathan to take up office on 1 July 2009
2009-03-24

Our new Rector and Vice-Chancellor, Prof. Jonathan Jansen, has indicated that he will take up office on 1 July 2009.

Speaking here at the Main Campus in Bloemfontein today after discussions with members of Council, Prof. Jonathan said he was deeply humbled by the overwhelmingly positive reception he has received from all quarters on and off campus following the announcement of his appointment.

“I have received telephone calls, e-mails, SMSs and messages from people who have nothing but support and seemingly lots of advice for me, which has humbled me tremendously. I am truly grateful for the trust shown in me by so many people I have not even met.

“This generosity and warmth is something that has reinforced my view that the University of the Free State is indeed a very special place for so many people and a place that I am honoured to serve as Rector and Vice-Chancellor.”

Prof. Jonathan said he would dedicate his first few months in office to a listening campaign to learn about the issues and concerns that are on people’s minds as well as the initiatives and developments at our university that make them proud of our institution.

“This is an important step because I don’t want to come across as some know-it-all who can come here and tell people this is what they should do. It is also an important step to get people talking and united about a common vision for the academic institution that the UFS is. It will have to be about the twin imperatives of racial reconciliation and academic excellence.

“In this process of listening and learning no-one will be excluded. I will talk to people on campus and off campus, including academic staff, support staff, the Qwaqwa Campus, students, parents, alumni, local business, the religious community, and our sport persons.

“I must also add that I have now bought my Cheetah and Bloemfontein Celtic jerseys, difficult as it was for me.”
