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.

Two degrees in three years for former teacher
2013-12-17

Jacqui Middleton

When Jacqui Middleton entered university in 2011, she did so alongside her daughter, both women enrolling for their first-year studies at the University of the Free State. Three years later and the mother of three have completed two degrees – a double feat achieved with distinction.

Middleton, a former teacher, will receive a BA degree in Corporate and Marketing Communications at the April 2014 graduation ceremony and a master’s degree in Sustainable Agriculture at the June graduation ceremony. With these two qualifications in the bag, Middleton will pursue her studies with a BCom Honours degree next year, as well as a PhD degree in Sustainable Agriculture.

“It was my first full-time studies since 1988,” says Middleton. “I was a teacher for 22 years and my husband kept saying that I needed to get out of the classroom and into the corporate world. I was reluctant because I was so passionate about education and my children were still at school.”

Things changed when Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, visited the Ikanyegeng Primary and High School in Jacobsdal – where she was a teacher – to deliver a motivational talk. Middleton approached Prof Jansen about a bursary. The next year, with the support of her family, she moved to Bloemfontein and stayed on campus studying for two degrees.

“For me it was a major step of faith because we were relying on my salary and I had to give that up to study, so we had to believe there is something bigger beyond the three-year period.”

Something bigger definitely awaited. Her study record of the last three years reflects a dedicated student who passed most of her subjects with marks higher than 80%. 

With her new qualification, Middleton will follow a career in agriculture and farming with her husband. ”I am still passionate about education, but now I am passionate about educating farmers to assist with the land reform process. Land reform is crucial for food security in our country and at the moment we need more success stories of black farmers moving from emerging to commercial farming. I believe that whatever you studied in life should not be wasted.”
