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.

We are very proud of our academic achievements, but without the human element, these achievements are not worth anything. This is according to Prof. Jonathan Jansen, Vice-Chancellor and Rector, who attended a meeting with the Thabo Mofutsanyana community in the Eastern Free State.

Prof. Jansen made the community aware that the university has two very important and interlinked projects – the academic and human projects.

“Our university has ambitions to produce the best scholars in various fields, but this cannot be done if we neglect the human aspect of doing things in the right way. We want to produce academic giants as much as we want to produce graduates of life,” said Prof. Jansen to an audience that included representatives from the traditional councils, business, religious and farming communities as well as the Maluti-A-Phofung and Dihlabeng Local Municipalities.

Prof. Jansen said that the memorandum of understanding that the university signed with the Dihlabeng Local Municipality in 2010 was already yielding positive results.

“There has been an enormous improvement in the matric results of the Dihlabeng schools that are part of our efforts to contribute towards building a brighter future for our children. We want to thank the municipality and the Honourable Mayor Tjhetane Mofokeng for being part of this partnership,” added Prof. Jansen.
 
“We are grateful that the university is considerate of its stakeholders in developing this Maluti-A-Phofung area. I am also aware that this institution has contributed towards the building of a crèche in the Mabolela village in Qwaqwa and for this we are very happy,” said Ms Linah Mnisi from Motlotlwane Projects and Consultants.
