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.

Prof Jeanet Conradie, professor in the Department of Chemistry at the University of the Free State (UFS), was the runner up in the senior category for Distinguished Women Researchers: Physical and Engineering Science in the Department of Science and Technology’s 2014 Women in Science Awards. With this award, female scientists and researchers are encouraged and rewarded, and also profiled as role models for younger women. 
 
Science and research, by which new concepts are discovered, is her great passion. Due to this keen interest in science, Prof Conradie studied a variety of subjects during her undergraduate years, providing her with a vast knowledge and the necessary background for her current main research interest, which is a combination of various scientific fields. Her PhD in Chemistry, as well as her strong background in Physics, Computer Science, Mathematics and Applied Maths, influenced her choice of research interest and expertise to gradually develop in the direction of computational chemistry, which is a beautiful combination of chemistry and physics. 
 
Today, Prof Conradie’s research expertise is in computational chemistry, using the super computer and appropriate software to simulate, understand and predict the behaviour of atoms and molecules in real life. The use of computational chemistry makes it possible to study chemical reactions and phenomena that are impossible or too dangerous to study experimentally. Her research team also performs experimental work in the laboratory to combine and compare with the computational analysis. Based on the results obtained, new materials with specific properties are developed. 
 
“We are very proud of Prof Conradie. This award is the result of 14 years of hard word, a lot of it after hours. We are fortunate to have someone like you as colleague who puts guidance to students and learners first in research, teaching and community service,” said Prof André Roodt, Head of the Department of Chemistry at the UFS. 
 
Prof Corli Witthuhn, Vice-Rector: Research said: “Prof Conradie serves as a role model for younger academic scholars in higher education through her motivation, productivity and drive. She also serves as an example of how female scientist can reach the top of their profession while juggling both professional and family responsibilities. This is well deserved recognition for her outstanding research achievements”
