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.

Medical student stars in local movie
2015-10-15


Sung-Hoon as the on-screen character Operator 2

Sung-Hoon Kim’s dream of starring in a movie became a reality with the release of Reconnect on 16 October 2015 in Nu Metro cinemas across the country.

The second-year medical student at the University of the Free State transitioned into a professional actor in December 2013, when he made the leap from his high school drama stage to shooting for the big screen.

“I did plays in high school where I had roles like Simba in The Lion King,” said the first-time movie star. 

The film is a purely South African creation. It is set in Potchefstroom and Klerksdorp, Sung-Hoon’s former and current hometowns. Sung-Hoon plays two major roles: XJ-1- a robot, and the on-screen role of artificial intelligence Operator 2 at SKY CORP - an international intelligence company that protects top secret information from around the world.

Reconnect was directed by the late Marius Swanepoel, who Sung-Hoon described as “a great blessing to all those privileged enough to have known him.” The movie explores the relationship between human beings and artificial intelligence.

Eric Scott discovers XJ-1 at an abandoned warehouse, and transfers him to SKY CORP where he becomes destructive. Eric and his friend, Jason, are then faced with the challenge of containing the situation, and saving the company which XJ-1 has infected with a dangerous virus. As the science-fiction action unfolds, viewers catch a glimpse into the life of XJ-1.

Shooting the movie was an exciting experience for Sung-Hoon. “It was quite fun because I like imitating voices,” he said.
