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.

Discourse on statues and symbols puts transformation questions in the spotlight
2015-04-12

 

Amid various protest actions against historical statues across the country over the last two weeks, the University of the Free State’s Institute for Reconciliation and Social Justice presented a three-day discussion session the past week about the role and place of statues, symbols and signs in the transformation attempts of universities.

During these lunchtime sessions, various speakers from different contexts had expressed their opinions about this issue that has become a focal point, not only for universities, but also for the country as a whole.

Thus speakers not only gave their opinions about whether there is a place in present-day South Africa for statues and symbols from colonial and apartheid-South Africa, but also highlighted the cultural-historical values and the more deep-seated issues and symbolism of the statue-debate.

UFS Rector and Vice-Chancellor, Prof Jonathan Jansen, said on the first day of the session that the discourse was not about only one person’s memories, but about everyone’s in the country. He proposed that similar sessions should be held at each university campus.

He also said that, instead of breaking down, people should learn to live together, and everyone should be involved for transformation to occur.

Speakers who served on the panel, included academics from the UFS and Stellenbosch University as well as representatives of the Student Representative Council and of historical and heritage foundations.
