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 Department of Sociology at the University of the Free State (UFS) recently held a departmental seminar where the former Vice-Rector of the UFS, Prof. Benito Khotseng, was the guest speaker.

He focused on the importance of the engagement between universities and the community. According to him South Africa has one of the most troubled societies in the world.

He said factors that led to people living in stress are, amongst others, unemployment, broken families, slum housing, child abuse, school dropouts, HIV/Aids, illiteracy and crime.

“People in the communities complain about what they don’t have when they should look at what they can do with what they do have,” Prof. Khotseng said.

He said the UFS was filled with people with the necessary expertise who should go to the communities to help where they could. “Universities and communities should start new, collaborating relationships,” he said.

“When we assist communities we should not see them as a bag of needs,” he said. “Each time someone uses his capabilities, the community grows stronger.”

He further said the UFS could certainly play a meaningful role in regional engagement and development.
