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.

UFS attracts excellent and diverse students

When Thato Monkoe and Matshediso Mokoena sat for their final matric examinations in 2014, all they had on their minds was not just passing, but passing well. Little did they know at that time that passing well would place so much responsibility on their shoulders.

 

Both Thato and Matshediso come from rural and disadvantaged backgrounds. They are first-year students at the Qwaqwa Campus of the University of the Free State, and are the first in their respective families to study at a university.

 

Thato describes his situation as “sad and good at the same time”.

 

“It is good, because I am the first one at home to have completed my matric and to have gone on to study at a tertiary institution. At the same time, it is sad as I feel sorry for my siblings who, for various reasons, did not have similar opportunities when they opted out of school”, said Thato, a BEd student.

 

”Now my sister and brother, as well as the entire family, perceive me as the one with brains, and this makes me uncomfortable. However, I am up for the challenge to be the first one to graduate with a degree in my family”.

 

Matshediso Mokoena, a BSc student, who obtained distinctions in Mathematics, Physical Sciences, and Life Sciences last year, concurs with Thato.

 

”As much as my family is supportive, there is always pressure as they expect the best from me,” she said.

 

“The pressure does not only come from my family. My entire community looks up to me, and they can’t stop talking about my achievements”, Matshediso revealed.

 

Both Thato and Matshediso are, however, happy that the dark cloud of doubt about academic achievement in their families has finally disappeared.

 

“At least someone in my family is hard at work carving her future, and willing to set a good example. That person is me”, said Matshediso, who aspires to be a medical doctor, and has a younger sister in Grade 8.

 

Thato and Matshediso are just two of hundreds of students making good use of the University of the Free State’s commitment to attract excellent and diverse students at both undergraduate and postgraduate levels, as reflected in the Strategic Plan 2015-2020.
