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.

Miss South Africa is a Kovsie
2014-04-01

 

Twenty-one-year-old Rolene Strauss, a third-year medical student at the University of the Free State (UFS), was crowned as Miss South Africa at a gala event at Sun City the weekend. Rolene was also the favourite on Twitter.

Another Kovsie, Dipalesa Mbolo, honours student in Business Management at the UFS, was also one of the finalists in the Miss South Africa pageant.

In her acceptance speech, Rolene said that she dearly loves South Africa. “This is where I can live, speak, learn and love freely. This is where my dreams come true. I am very proud of our country and shall always have a purpose here,” Rolene said.

Rolene said that Prof Jonathan Jansen, the Vice-Chancellor and Rector of the UFS, is an inspiration to her. “He stands up for what he believes in and enjoys what he is doing. He wants the best for his students and supports them in everything they do,” she said.

The university community is very proud of Rolene, and it is confirmed by Prof Jansen. “I am extremely proud of Rolene Strauss, for she has proved that physical beauty, academic excellence and public duty can come together in one person, and offer a powerful platform for transforming communities in need that would otherwise remain invisible, were it not for such a wonderful young role model,” he said.

On the year which lies ahead, Rolene said: “It will be a year during which I shall give back, say thank you and be a good example of the potential that especially women and South Africans may have in our country.”
