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.

Nothing beats hard work, says Kovsie
2011-10-13

 

Khethiwe Mtshali

Khethiwe Mtshali is a classic example of a go-getter. This hard-working 23-year-old student from Ladysmith, who is currently studying at our Qwaqwa Campus, strongly believes in her own abilities. She believes that hard work pays off and that a person will be richly rewarded if you give it your best. Khethiwe has recently returned from a month-long visit to China where she was stationed at the Fresh Water Fisheries Research Centre of the Chinese Academy of Fishery Sciences in Wuxi City.

“I was nominated to go to China to learn and conduct research, as South Africa lacks expertise in the field of food security and related fields of science,” says Khethiwe, a 2011 recipient of the Golden Key Award and an M.Sc.in Zoology student who specialises in Parasitology.
 
“The Chinese is a hard-working nation that I wish we could emulate as South Africans. Doing my research on parasitology of fish and other related agricultural diseases over there was a worthwhile experience that will not only benefit me as an individual, but the entire Parasitology Division of the Department of Zoology and Entomology at the Qwaqwa Campus. This research is surely going to put the university and the entire country in a better position to compete with the best in the field of parasitology,” Khethiwe said.
 
After completing her B.Sc. degree in 2008, Khethiwe worked as a teacher at Ezakheni High School for a year before she was summoned back to our university by her mentor and Head of the Department of Zoology and Entomology, Dr Oriel Thekisoe, where she studied towards an honours degree, which she passed with distinction last year.
 
“If it had not been for Dr Thekisoe, I think I would still be a teacher whose potential would not have been tapped to the maximum. I wish to thank him for pushing me to do my best at all times. He has taught me that where there’s a will, there’s a way,” Khethiwe said.
 
The best is yet to come for this proud Kovsie who can teach you a thing or two in Chinese!
