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.

Avant-garde filmmaker. Renowned feminist scholar. Revolutionary Prof Laura Mulvey.
2014-06-27

Prof Laura Mulvey – currently a professor at Film and Media Studies at Birkbeck, University of London, is about to visit the Bloemfontein Campus. As a tribute to her achievements, the UFS is bestowing an Honorary Doctorate on her during our Winter Graduation Ceremony. In addition, two events are scheduled during which the public can get to know Prof Mulvey and her films better.

Prof Mulvey is a hugely influential figure in the international arena of film and visual media. She is globally recognised as an eminent feminist film scholar and worked at the British Film Institute for many years. During the 1970s and ‘80s she exploded onto the scene as a prominent avant-garde filmmaker.

During her visit, she will discuss a film with Prof Annie van den Oever (University of Groningen) and some of her most renowned film material will also be screened.

Under the Skin of the City (Iran, 2001), directed by Rakhshan Bani-E'temad, will be screened in full on Thursday 3 July 2014. The film centres on the trials and tribulations faced by an Iranian family. This award-winning film will resonate with a South African audience because of the social issues it addresses. Prof Mulvey and Prof Van den Oever will also discuss the film afterwards.

On Saturday 5 July 2014, Prof Van den Oever and Prof Mulvey will have another discussion and the audience will be treated to snippets from her prominent films.

The details of these events are:
