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.

The Department of Economics in the Faculty of Economic and Management Sciences held a reception for its top 50 students on 10 October 2016 on the Bloemfontein Campus.

Speaking at the event, Mr Rocco Carr, business development manager at Glacier Investments by Sanlam, encouraged students to enrol for postgraduate studies in Economics and Financial Economics. He said the South African economy was not stable at the moment due to various factors such as politics. However, it was interwoven with the global economy and circumstances might change to make the country prosperous again in the future. ”The interest rates, the upcoming presidential election in the US, the economic changes in China, Brexit, and the economic changes in the European Union are some of the factors that are at play in the South African economy,” he said.

He further encouraged students to be prepared for the workplace by developing their work ethic and learning to take responsibility as this would help them grow a successful career despite economic volatility.

Dr Johan Coetzee, acting head of the Department of Economics, said the three honours programmes – Economics, Financial Economics and Investment Management, and Applied Econometrics – were internationally accredited and could open many doors to students. “Training is not only about what you can do, also how you think and how you manage people. Managing people has become more important than ever before,” Coetzee said.

The department hosts its top 50 students each year to expose them to courses they can take at postgraduate level and the career opportunities that lie ahead.
