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.

Any phase in a learner’s life can be the right time to explore science. As for Grade R learners at Nzame Primary School in Mangaung, it all started when their Deputy Principal, Charles Busack, attended the Global University for Lifelong Learning (GULL) workshop coordinated by the university’s Community Engagement in October 2016. The GULL network enables its affiliated organisations to recognise the individual and collective efforts of those who are creating progressive transformation in communities and in the workplace. Consequently, a community-based initiative, Science4Fun, was developed and launched at the primary school, where learners would start to experiment with science through play.

University students instrumental in teaching
Every Tuesday morning, these fun science activities form part of the foundation phase programme, in which Dr Elizabeth Conradie of the Central University of Technology (CUT) and four postgraduate Science students from the UFS, engage teachers and learners in exciting experiments and demonstrations. 

Most people just know pyramids as big, impressive structures built a long time ago in Ancient Egypt. However, for Grade R learners at Nzame Primary, their basic Geometry insight about shapes advanced to engineering skills when they built modern pyramids, connecting jelly sweets and sosatie sticks.

Laying a foundation for the future
According to Dr Conradie, more fun exercises are lined up for curious minds, exploring other sciences such as Chemistry and Mathematics, combined with music. The initiative will assist to equip learners with the basics of Science into more advance learning phases of the schooling years, giving them an advantage.
