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.

Imagine sharks with laser beams attached to their heads and enzymes that wear coats, and yeasts that stage a coup d’état in your body when agitated. This was all explored at the FameLab Science Communication Competition. 

Hosting the FameLab regional competition was a collaborative effort between Dr Mikateko Hoppener, from the University of the Free State’s (UFS), the Centre for Research on Higher Education and Development (CRHED), and Edith Sempe from the Central University of Technology (CUT), Research and Development Unit. Taking place for the first time in the Free State, the event was held at the UFS Centenary Complex on 2 March 2017.

Witty minds make science fun
FameLab is a competition that promotes science and technology by creating a space for scientists to find their voices and reach public audiences. The Free State regional competition had 18 contestants and two emerged victorious on the day. Contestants had to ensure their three-minute talks were fun, charismatic, clear and entertaining.

The two regional winners were Oluwasegun Kuloyo, a PhD student with the department of Microbial Biochemical and Food Biotechnology at UFS, and Zanele Matsane, a Construction Management PhD student at CUT. 

Kuloyo's research deals with the management of the candida yeast which exists in most people’s bodies and which, with a healthy immune system can be kept under control, but when an immune system is compromised, the yeast reacts volatilely and can potentially lead to death in HIV/AIDS patients. 

Matsane’s research is centred on collaborative construction management inspired by the Toyota manufacturing process. She hopes to resolve the silos of construction and bring about a more harmonious and fluid process to construction projects, thus ensuring their successful completion. 

The panel of judges consisted of Oteng Mpete UFS Media Liaison Officer, Dr Elizabeth Conradie from the CUT Innovation Hub, and Prof Willie du Preez from the CUT Centre for Rapid Prototyping and Manufacturing, as well as Robert Inglis from JiveMedia Africa.

Local scientists become jet-setters 
The two regional winners will head to Johannesburg to compete at the FameLab national semifinals, and the South African winner will go on to compete against winners from over 30 countries on an international stage, at the Cheltenham Science Festival in the UK.

FameLab is a programme of the Cheltenham Science Festival and is implemented locally by the South African Agency for Science and Technology Advancement (SAASTA), the British Council, and JiveMedia Africa. The competition has been running in South Africa for the past five years.
