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.

Qwaqwa Campus kicked off the 2017 graduations season of the University of the Free State in style when over 550 degrees and certificates were conferred in three sessions on 12 and 13 May 2017. These included five PhDs from the Faculty of Natural and Agricultural Sciences.

In his maiden speech delivered during the two ceremonies on Friday 12 May 2017, the newly-appointed Vice-Chancellor and Rector, Prof Francis Petersen, emphasised the interconnectedness of graduates with other stakeholders in their communities.

“Never forget the role played by other people who sacrificed a lot for you to be here today. Recognise the extra mile that someone was willing to go for you to graduate,” he said to an enthusiastic audience that included Grade 12 learners from neighbouring schools. 

Prof Petersen also reminded the graduates that not everybody had an opportunity to enter, enrol, and eventually graduate at a university. “You are part of the privileged few, and I am confident that the UFS has given you an equal opportunity to reach your full potential. You have had years of exposure to ideas and experiences on diversity. You now have the opportunity to show the world and to use what you have learnt beyond a classroom,” he added.

“Go out there and open doors for others as much as they were opened for you. I implore you to carry over your experiences of diversity and use them to build a better world. Go out there and build a better world, not only for yourself but for everyone in need. Expand your influence, reach out, and be accountable,” he said.

“South Africa needs your skills,
innovation, knowledge, expertise,
and creativity.”

Make your own unique contribution
The session held on Saturday 13 May 2017 saw the Principal of Motheo TVET College and Qwaqwa Campus alumnus, Dipiloane Phutsisi, having a heart to heart with the graduates from the Faculty of Education.

“Our contribution to the world as graduates will not be measured by the wealth we accumulate or the accolades we receive, but rather by the way in which we share our unique gifts with the world. And the only place to find those gifts is to look within yourself. As the class of 2017, make your own unique contribution,” she said.

“Your graduation takes place at a particularly challenging time in the history of our democracy. It happens at a time when our nation is engulfed by racial polarisation, anger, confusion about what democracy and freedom mean to us, and at a time when the pillars of morality are tested.”

“As you graduate, I wish to remind you that our country needs you more than ever before. South Africa needs your skills, innovation, knowledge, expertise, and creativity,” she said.

Three members of the current SRC were also among the graduates. They are the President, Njabulo Mwali (BSc Information Technology), Sports Affairs Officer, Ntokozo Thango (BA Sociology), and Student Development and Environmental Affairs Officer, Ntokozo Masiteng (BA Sociology).
