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.

Thabo Sithole, a PhD student at the University of the Free State’s (UFS) Faculty of Education, was recently awarded a prestigious award during the provincial National Teaching Awards in November at which he was celebrated along with other teachers from the Free State.

Sithole was awarded for excellence in teaching Physical Sciences, using a variety of strategies to appeal to the different abilities of learners.

He holds a BSc Medical Microbiology, BSc Chemistry, BCom Economics, BSc Hons in Chemistry, BCom Hons in Economics and MA in Mathematics. To qualify to become an educator, he completed his Postgraduate Certificate in Education (PGCE) at UFS.

Apart from teaching, Sithole assists youths confronted with substance abuse and was instrumental in getting funding to assist young people in Jacobsdal. The Albertina Sisulu Youth Recreation Centre in the town now receives annual funding from the Free State Department of Social Development.

Through the National Teaching Awards, the Department of Basic Education acknowledges the extraordinary efforts of teachers, often achieved under very difficult conditions and in service to children from underprivileged families and economically depressed communities.

Leadership is a crucial element to all schools functioning at optimum with all teachers, learners and parents moving forward with a common vision for the improvement of the school.

Sithole’s work also focuses on clustering childhood development centres to work together in order to enhance the preparedness of learners entering primary school. The MEC for Education, Mr Tate Makgoe, said the National Teaching Awards recognised and promoted excellence in teaching.

The UFS Faculty of Education congratulated all teachers in South Africa who worked tirelessly to build a better future for all learners.
