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.

The University of the Free State (UFS) is well on course for delivery on its most important academic duty as a research university. This was the message that came forward at the launch of the 2010 Annual Research Report of the UFS on 30 August 2011.

Speakers at the launch, which included Prof. Jonathan Jansen, Vice-Chancellor and Rector, as well as Prof. Driekie Hay, Vice-Rector: Academics outlined the key strategies and achievements of the UFS for the 2010 academic year. This included the establishment of a Postgraduate School at the UFS, the first of its kind at a public university in South Africa. Prof. Hay told guests that the aim of the Postgraduate School was to broaden research and deepens scholarship on postgraduate education in the country. She highlighted some initiatives the UFS undertook in 2010 to build and maintain its intellectual capital. Some of these initiatives included the appointment of seven senior professors and recruiting more female and black scholars and academics.   
Also speaking at the event was Mr Robert Kriger, the director for Policy and Strategy at the National Research Foundation (NRF). Kriger reflected on the brilliant minds of scholars such as Archie Mafeje, Lewis Nkosi and Dennis Brutus and argued for efforts to increase the country’s research output.
Some highlights of the 2010 Annual Research Report:
  • The total funding available for research at the UFS increased from approximately R199 million in 2009 to just over R210 million in 2010. A total of R31.8 million was made available from central university funds.
  • In 2010 the UFS was home to 92 NRF-rated researchers. During 2010, four researchers applied for re-evaluation and of these, two improved their rating, while a further five received a first-time rating.
  • The Faculty of Natural and Agricultural Sciences continue to be the most prolific producer of publications in accredited journals, while the Faculty of Education has shown a 54% increase in its publication output.
  • Staff members in the Physics department at the UFS Qwaqwa Campus published 22 papers in international peer-reviewed journals during 2010.
  • Also at the Qwaqwa Campus: Ms Khethiwe Mtshali,a postgraduate student in the parasitology research unit of the Department of Zoology and Entomology, received a best Honours presenter award at the 1st Annual Research symposium of the National Zoological Gardens of South Africa.
