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 Mary Kay Blakely from the Missouri School of Journalism (USA) speaks about the age of misinformation

Living in an age where misinformation is as common as loadshedding in South Africa, we all tend to ask who we can trust when reading or hearing the news media.

Prof Mary Kay Blakely from the Missouri School of Journalism (Columbia, USA) presented a public lecture recently entitled The age of misinformation: Who do you trust? at the UFS. She stressed the point of how, with the social media revolution and the rise of the citizen journalist, our news interests of old are being fed by many more new channels, influences, and opinions. This leaves us to question what is still true and what is still objective

For example, Blakely mentioned that “gossip, scandal, and celebrities have always been our fascination – even more so today.”

“But nowadays, we have to become even more critical thinkers.”

During Blakely’s presentation, she stated the harsh reality that objectivity is extremely difficult. True objectivity, which means keeping  yourself completely out of the story you cover, is virtually impossible.

“It is not just about covering both sides of the story. Often, there are far more sides to a story than just two, probably even five.”

Therefore, it comes down to fairness, balance, and truth, which are really important in covering a story. Hence, it is the obligation of the media to be fair, balanced, and truthful while recognising their own biases.
