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.

Digital Storytelling empowers and liberates students
2014-10-17

In January 2014, Jode Brexa, an American Fulbright scholar, came to our university and moved into the guest room at Welwitschia residence.

It so happened that Brexa and Elize Rall, residence head of Welwitschia – better known as Wel-Wel – started talking about digital storytelling. Brexa’s Digital Storytelling project captured Rall’s imagination. Shortly thereafter, Brexa convinced the RC members of Wel-Wel to participate in the project.

Digital storytelling is, on the most basic level, the use of computer-based resources to tell stories. The idea is to combine the art of storytelling with multimedia – including graphics, photos, text, audio, image and/or music.

The Wel-Wel students were taught storytelling skills and each student’s unique story was recorded and edited. It was so successful that they then showed their stories to the Rector and Dean of Students. Brexa will now – with their permission – take their stories to America with her, where she will share it with her community.

During the weekend of 10–12 October 2014, the RC of Wel-Wel introduced 12 learners, who are currently in Grade 10 at the Christiaan Liphoko School, to the project. The learners stayed in the gazellie for the weekend and, in the course of a few days, learned how much power is locked up in their personal stories. They learned that everyone’s story has the power to inspire and empower.

Wel-Wel has been involved in various outreach projects to the community. However, this was the first time that Wel-Wel literally brought the community to their doorstep. This is also not a charitable project. It is uplifted students reaching out to the youth to empower them in order to empower others in turn.

Meanwhile, Brexa also linked the project to the university’s Schools Partnership Project. The programme works through mentorship programmes to uplift previously disadvantaged schools. Hands were also taken with Columba Leadership NGO – financed by Old Mutual.
