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.

Meet the person behind the title – your new FaceOfFacebook
2015-04-29

Kovsies #FaceOfFacebook was born three years ago out of a need to engage with students, and become a virtual friend. Auditions are held every year to choose the new ‘face’ representing the UFS on Facebook. The successful candidate holds the title as #FaceOfFacebook for the next 12 months, attending events, and filming short video clips to post on our Facebook page.

 

The votes have been counted, and we have a winner. After much excitement and a close contest, Nompumelelo Maseko (whose name, fittingly, means ‘success’) emerged victorious from the top six contestants selected by our panel of judges. We sat down with the soft-spoken Mpumi – as her friends call her – to get a sense of the person who will be our ambassador for the next year.

 

What is your field of study, and how far along are you?

I am studying for a BSc degree in Genetics, and I’m currently in my second year. I have a particular interest in the forensic sciences, which fascinate me!

 

Are you originally from Bloemfontein?

No, I am originally from Pretoria.

 

How is it that you ended up here, studying at the UFS?

Before leaving school, I applied to various universities, but my desires and ambitions brought me here.

 

How do you find your residence?

Akasia ladies are big on sisterhood, very supportive. Res life is very enjoyable.

 

What do you hope to accomplish during your term as the #FaceOfFacebook?

I would like to help people become aware of what is taking place on campus. There are many opportunities to be more engaged with what is happening at the varsity. For instance, there are still many people who don’t really know what the #FaceOfFacebook is, and I would like to help inform them about it.

 

What is your motivation in your studies, in taking part in this contest, and in life?

I am intrigued by the function of life forms, the differences that exist at a cellular level.
For this competition, I fed off my love of people, even though I am shy. I also enjoy presenting.


I have my parents to thank as my motivation, as well as meeting and engaging with people. I find that I achieve a broader perspective when I don’t restrict myself to my own opinions, but strive to be open to differing views.

 

Nompumelelo will be appearing in one of her first Facebook videos shortly, so be sure to keep an eye on our Facebook page.
