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.

Understanding the nature of prominence
2014-03-14

 

What did Hendrik Verwoerd and Steve Biko have in common? Or perhaps Johannes Kerkorrel and Brenda Fassie?

“They all possessed a certain natural predisposition to prominence,” says Prof Paul Fouche, reseacher in psychobiography at the University of the Free State’s Department of Psychology.

Prof Fouche and a team of researchers from other South African universities released findings on psychobiographical studies done on personalities that played a great role in our history.

The studies show that notable historical figures were very often prolific readers with a passion for literature since childhood. Generally, they also had a great love for nature and a sense of the sacredness of it, as well as a love for the cosmos.

The study further reveals that many of them were forced to take up leadership roles in the family from a very young age and were driven to succeed in order to take care of their own.

In many of these cases, there was a strong partner who supported the leader while they went about the business of governing their world.

Psychobiography is the systematic and descriptively-rich case study of renowned, enigmatic or even contentious individuals in socio-historical contexts within a psychological frame of reference. Over the past decade, psychobiography has become an established research genre and a methodology used by various academics and scholars in the field of life history research.
