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.

Prof Luyt says young researchers should not allow circumstances to determine their future

Young researchers, who spend their life at a disadvantaged and rural campus like the University of the Free State’s Qwaqwa Campus, should not be deterred from achieving their dreams.

This is the view of Prof Riaan Luyt, former Assistant Dean in the Faculty of Natural and Agricultural Sciences, who achieved his B-rating by the National Research Foundation (NRF) late in 2015. This was by far the highest-ever rating on the Qwaqwa Campus.

“When I moved to the Qwaqwa Campus many years ago, having had the opportunity to do a post-doctoral fellowship in Polymer Science at the Leeds University in the United Kingdom, I was determined to get the Department of Chemistry off the ground, and to embark on serious research,” said Prof Luyt, who is now the Affiliated Professor in the Department of Chemistry and Research Associate Professor at the Centre for Advanced Materials, based at Qatar University.

“It was through sheer determination that I managed to obtain enough funds to equip a decent research laboratory. There were many obstacles over the years, but I managed to attract more and more postgraduate students and published more,” he said.

At first, Prof Luyt was not successful with his NRF-rating applications.

“My first couple of attempts to get rated produced no success. I was then awarded a C3-rating, which was later followed by C2 and then C1,” he added. “Getting a B-rating is the highlight of my research career. It shows that it can be done. Young researchers should not allow their past or present circumstances, or their work environment to stand on their way,” said Prof Luyt, who has supervised 38 master’s and doctoral students as well as 11 postdoctoral fellows. He has also published 185 papers in international and accredited journals.

Although abroad, Prof Luyt will continue to supervise eight postgraduate students at the Qwaqwa Campus.
