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.

Since the 1800s the manipulation of photographs has been common practice, and who can forget the OJ Simpson Time magazine cover in 1994? Albe Grobbelaar, lecturer in the Department of Communication Science at the University of the Free State (UFS), asked in a special lecture on 18 August 2017 whether “Photo manipulation in Journalism” was an evil habit, a crutch or a lifebuoy.

“As a journalist I have always been interested in photography. And the principle of photo manipulation or tampering with photos, as we call it, is something that has interested me ever since,” Grobbelaar said. Photo manipulation is an area that has garnered many academic interest and is not a new trend but a practice that started in the 1830s when photos came into popular use. “It is not always done with ulterior motives, artists played with photographs to get unique effects.” Photo manipulation is not only to create fake news, but is sometimes used to convey novelty and create shock to news readers. 

Different viewpoints for different circumstances
He talked about the spectrum of viewpoints on photo manipulation. Some conservative journalism schools say photos should never be retouched while other feel it is fine to tamper with pictures. “What I tried to convey in the lecture was that one should consider different circumstances differently,” Grobbelaar said. As a journalist he believes that news photos should never be manipulated.

He mentioned the example of the mugshot of OJ Simpson that the Los Angeles Police Department released to the media. “Newsweek and Time both used the photo on their front pages, but Time deliberately darkened the picture so that OJ, a black man, would appear more sinister,” Grobbelaar said. It is, however, common practice in the fashion industry to retouch images that are used in fashion magazines. 

Use own judgment to validate photos
In the age of social media it has become easy to manipulate photos and which has been labelled fake news. “I would advise people to use their own judgment when validating the authenticity of photos,” Grobbelaar said. It is important to verify whether they are from a reliable news outlet.
