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.

National U21 Hockey Player of the Year is a Kovsie
2015-09-16

 
The best U21 hockey player in the country
for 2015, Nicole Walraven

Nicole Walraven, a student at the University of the Free State (UFS), had a pleasant surprise waiting for her on 29 August 2015. She had participated at the Women's Interprovincial Tournament in Potchefstroom, and watching the finals from the stands with her family when the announcement was made.

“They announced that they were going to award South Africa’s (SA) Under-21 player of the year. It did not even go through my head that I could stand a chance of winning it. Then next minute, I hear my name being called. ”

“To win such an amazing award means so much to me. To be acknowledged as SA Under-21 player of the year of the entire country is still something that hasn't sunk in yet; I still can't believe it,” remarked Nicole.

Prior to this tournament, the 20-year-old was selected by the South African Hockey Association to represent South Africa, at senior level, at the World League in Spain and has again made the senior squad for selection to play in the Africa Cup of Nations tournament in October.

Nicole, a descendant of hockey players, is ambitious about winning the Africa Cup, which would open doors to the Rio Olympics.  “It is my biggest dream to go to the Olympics. If I had the chance to go, I would be the 4th generation Olympian in my family,” she said.

In addition to her family, the final-year BA Human Movement Sciences student, credits her lecturers for her ability to juggle academics and a thriving sports career successfully.

“I owe it to my lecturers and the University for making it possible for me to pursue my dream as well as my studies,” she said, “It hasn't been easy, and I've had to make a lot of sacrifices but it's most definitely worth it.”

Also representing Kovsies on the SA Women’s Hockey team are Liné Malan and Tanya Britz.
