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.

Postgraduate students and their academic 'parents' at the University of the Free State (UFS) now have a dedicated physical, emotional and electronic space to provide for their specialised needs in order to further promote research excellence at the UFS.

The university's Postgraduate School was launched in May 2011, but ventured further in the quest to fulfil and expand its mandate with new initiatives. These different aspects of the school were launched on Wednesday 8 May 2013 in the CR Swart Auditorium on the Bloemfontein Campus. The postgraduate strategy, postgraduate prospectus, the website and the headquarters of the Postgraduate School in the Johannes Brill Building were all unveiled and launched.

Prof Driekie Hay, Vice-Rector: Academic, who was a major driving force behind the formation of the Postgraduate School, during her address at the opening emphasised the multifaceted and unique relationships which often exist between students and supervisors.

Prof Hay, who has a distinguished academic background in postgraduate teaching, made plain her expectations for the Postgraduate School. She said it aims to "create an intellectual space for postgraduate students and supervisors" in order to produce world-class intellectuals at this university.

She said the school will empower both students who often don't know what to expect from supervision, as well as supervisors who often lack supervision skills. Through this it will be possible to create healthy, productive relationships between the distinct pairs in often misunderstood, unbalanced and intricate interactions.

Dr Henriette van den Berg, Director of the Postgraduate School, introduced the strategic plan of the school and emphasised the great strides that have already been made and what still needs to be done at the UFS in terms of postgraduate teaching. According to her, the Postgraduate School aims towards "holistic development of postgraduate students with transferable skills," through a multi-level and institution-wide approach at the university.

"Our aim is to develop a one-step service for postgraduate students, involving all the different stakeholders," she said.

The new Postgraduate School website was also showcased during the event. Reachable through a number of avenues on the main website, the site offers a digital version of the Johannes Brill Building. Brimming with features catering specifically for local, international, current and prospective students, the website provides crucial information.

The Johannes Brill Building's refurbished interior, with staff offices, seminar rooms and social spaces, were also showcased to UFS' staff and students. The initial phase of the Supervisors' Wall of Fame was also unveiled. According to Dr van den Berg , the wall will after completion bestow much-deserved praise on a hand-picked group of 60 supervisors who have respectively been responsible for more than 300 and more than 500 successful PhD and master's candidates over the past decade.
